SOC 47-2121 · O*NET 47-2121.00
Glaziers correspond to O*NET/SOC47-2121.00: installing glass in windows, skylights, store fronts, display cases, building fronts, interior walls, ceilings and tabletops, including mirrors and repair. US 2025 wages use this occupation's own data; the current 2025—2035 projections come from the BLS Occupational Outlook Handbook and are kept separate from the older O*NET trend. Specific tasks, training and authority are checked against the real role.

H1 only observes unit recalculation, evidence stratification and traceable correction; it cannot verify glass handling, real product acceptance, qualifications, safety competence, long-term fit or employment outcomes.
Caution signals | O*NET also shows (47-2121.00, percentage response basis): using hands to handle, control or feel objects, tools or controls 82% continually or almost continually; standing 61% continually or almost continually; being outdoors exposed to all weather 54% daily; wearing common protective or safety equipment 74% daily; physical proximity to others 69% moderately close (at arm's length) and 27% very close; importance of being exact or accurate 49% extremely important. This occupation works with glass (including at various sizes), curtain walls, windows and doors, mirrors, lifting and work at height, and one failure to protect work at height, lifting, or scaffolding and rigging, one unchecked glass specification, appearance or toughened and laminated marking, one out-of-tolerance layout or plumb deviation or unhandled mismatch between frames and embedments, or one unisolated broken or falling glass can cause personal injury, falls and cuts, product scrap and structural safety hazards, and may also involve construction safety, work-at-height, lifting and hoisting and special equipment and occupational health management systems. This occupation is mainly on-site hands-on work; the entry education requirement is not high, but the safety requirements for work at height, lifting and transport are high. If you find it hard to face work at height, the outdoors and heavy lifting long term, find it hard to accept cutting and fall risk and schedule pressure, or are unwilling to take responsibility for the traceability of layout, installation and acceptance records, these should be treated as real costs that need careful weighing.
O*NET profile of this occupation: 27 tasks and a work context of handwork, face-to-face contact, exactness and teamwork; wages use the 2025 figures for this occupation and the current projections come from the BLS OOH; the O*NET page this round has also been updated to 2025—2035. The 2025 US national wage for this occupation 47-2121 has a median of 57,080 USD per year and 27.44 USD per hour. OEWS includes production bonuses and commissions and excludes non-production bonuses, overtime premiums, shift differentials, benefits and self-employment; it is not total compensation or actual personal take-home pay. Percentiles are positions in the distribution and do not correspond to experience, qualifications or starting pay. BLS Occupational Outlook Handbook current 2025—2035: Glaziers 47-2121 employment 59,200 to 60,300 people, growth 2% (rounded in the Handbook), a net gain of 1,100 and an average of 3,900 openings per year; openings include growth and replacement and are not net gains or job advertisement counts. The direct projection table shows growth of 1.9% and employment including self-employment; the O*NET detail page this round already shows 2025 employment of 59,200 people, a 2025—2035 growth band of 1% to 2% and 3,900 openings, consistent with the current BLS period; the growth band does not equal the direct table's precise 1.9%.
Career direction comparison
Preface | the comparison below is laid out in four columns: occupation direction, core work and outputs, key differences, and which choice fits better. Curtain walls, windows and doors, interior fit-out, metalwork and unit paving often connect within the same main contract or fit-out project, but connection does not mean they are interchangeable; when choosing across directions, the object, process, codes, permits and responsibility boundaries of that direction must be learned anew.
| Occupation direction | Core work and outputs | Key differences | Which choice fits better |
|---|---|---|---|
| This occupation: Glaziers (O*NET/SOC 47-2121.00, Glaziers) | Core work and outputs: read and interpret blueprints and specifications, set out and determine plumb and measure dimensions, install frames, embedments, stops and hardware, cut, prepare and grind glass, set, fix, caulk and seal, hoist large and heavy glass with suction-cup cranes and hoists, erect and dismantle scaffolding and rigging, communicate with clients, select materials and treat surfaces; the outputs are installation results meeting the specification, sealing and safety requirements together with layout and acceptance records (O*NET/SOC 47-2121.00). |
AI's impact on the occupation
Insufficient evidence: no precise generative AI exposure level, adoption rate, substitution rate or income causality for 47-2121.00 was obtained. Editorial analysis may explore assistance with drawings, lists and record drafts, which must be verified against the original, and ordinary software or automated questionnaires must not be equated with AI. The O*NET detail page lists six software categories — CAD, work orders, Office, Windows, project management and Excel; the hot technologies page lists only Office and Excel with job-posting mentions each below 1% and Windows with an NA share, based on 2025 US Lightcast unique job advertisements. These are not on-site usage rates, AI adoption rates or productivity evidence. AI Impact Score 8% is an editorial estimate.

Occupation fit guide
First complete the H1 paper area, joint width, missing permit and version checks, which only observe recalculation and traceable correction; they do not verify glass feel, real safety, qualifications or long-term fit.
You may be better suited to： Fit signals: willing to be responsible for installation quality and site and personnel safety within the scope of codes and authorization; able to switch between construction sites, workshops and transport while keeping dimensions and sealing in focus; able to hold to the codes and review under schedule, height and hoisting pressure and to report per the system when anomalies occur or authority is exceeded.
These situations require caution： Caution signals: difficulty facing work at height, the outdoors, heavy lifting and cutting risk long term; or difficulty accepting schedule pressure and rework accountability; or unwillingness to report and hand over per the system when authorization is exceeded.
Do an entry exercise： First complete the H1 paper area, joint width, missing permit and version checks, which only observe recalculation and traceable correction; they do not verify glass feel, real safety, qualifications or long-term fit.
Work pressure, risks and occupational boundaries
O*NET responses show 82% using their hands continually, 61% standing continually, 54% outdoors daily and 74% wearing common protection daily, with 24% exposed to minor injuries daily. These are category proportions, not accident rates or severity; the following are editorial risk checking scenarios.
Risk basis: O*NET tasks and context are used to identify the process, and the BLS Handbook describes risks such as cuts, falls and solvents without giving accident probabilities for this page. For mainland China, verify against the actual activity: Article 28 of the Work Safety Law covers training and Article 30 provides for special operation qualifications; Article 2 of the Special Equipment Safety Law covers the catalogue and Article 14 covers the qualifications of relevant personnel, while Articles 39—42 cover maintenance, inspection and handling of abnormal conditions, so ordinary rigging or suction cups are not automatically all listed in the catalogue on the strength of their name; statutory inspection is checked separately against Articles 50—51 on bodies and personnel. Articles 34—35 of the Occupational Disease Prevention and Control Law cover training and health examinations for those exposed to hazards. The Ecological Environment Code takes effect on 2026-08-15 and repeals the old Environmental Protection Law, and Articles 80/150—151 on monitoring authenticity, emissions and permits are checked against the activity. Articles 4/6/13/19 of the Personal Information Protection Law apply to identifiable personal information, and ordinary glass drawings, dimensions and coordinates are not automatically personal information. On-site protection, scaffolding, hoisting and construction conditions are checked against the real process and the applicable systems, and no nationwide uniform certificate is inferred from the occupation name.
Entry, qualifications and career development
Editorial preparation path: check training and apprenticeship, mentoring and assessment, applicable qualifications and job authorization against the real target tasks; if interested, explore installation, cutting or technical documentation directions further. This is not a uniform promotion ladder and no transfer success rate or duration was obtained. O*NET asks what education new entrants need; 44% answered a high school diploma or equivalent, 36% less than high school and 12% a postsecondary certificate; this is not the education already held by existing workers. Job Zone 1—2 and SVP below 6.0 are a general preparation description, not a uniform apprenticeship duration for this occupation. In the US, learning usually takes 3—4 years through an apprenticeship or on-the-job training, and most apprenticeship programmes require a high school equivalent and being at least 18 years old; some states require licensing, which is checked by specific state and cannot be used as a uniform mainland China entry requirement.

Pre-employment verification notes | the following six items are for checking one by one before applying and starting work, to avoid inferring actual duties and authorization from the job title or promotional wording; the results should be based on written recruitment information, the labour contract, the job description and the construction, safety and quality system documents, and should be confirmed continuously after starting. This page only lists verification directions and does not constitute a formal list of conditions for any institution or project. Special note: this occupation often involves work at height, at edges and at openings, hoisting, temporary electrical supply and transport and glass cutting, so be sure to confirm the role's specific requirements for safety training, protective equipment, work permits, certification and data disclosure.
Verification point notes | similar job titles can differ greatly in duties and authorization: some focus on curtain wall and unitised panel hoisting and installation, some on commercial and residential windows, doors and glass doors, some on mirrors, enclosures and partitions, some on cutting, machining and preparation, and some on vehicle glass removal and installation; institutions and jurisdictions also differ in authorizing work at height, hoisting and temporary electrical work, glass specification changes, concealed work, acceptance and data disclosure.
| This occupation covers glass installation in building windows, skylights, facades and mirrors and tabletops; adjacent directions are compared by vehicle, wood and similar material, interior panel, sheet metal and unit paving tasks, and job authority is checked separately. |
| Better suited to people who are willing to work on construction sites, in workshops and during transport, can complete layout, measurement, cutting, installation and sealing to blueprints and codes, work in line with work-at-height, hoisting and protection requirements, and are willing to coordinate with the main contractor, supervisor and crews. |
| Automotive Glass Installers and Repairers (49-3022.00) | Vehicle glass tasks: removing and replacing or repairing windscreens and windows, cleaning adhesive layers, bonding and condition checks and restoring related components; ADAS requirements are checked separately by specific role. | Vehicle glass covers vehicle window removal and installation, bonding and repair; this occupation covers building and interior glass. ADAS calibration must be checked separately by vehicle model and actual role, and it cannot be said that all 49-3022.00 roles do it. | Editorial choice note: if you prefer vehicle glass, check the repair tasks and training further; interest alone does not prove fit. |
|---|
| Carpenters (47-2031.00) | Carpenters measure, mark and machine to drawings and make and install structures, frames and so on of wood and similar materials; it is not only wooden decoration. | Carpenters make, install and repair structures and fixtures of wood and similar materials; this occupation mainly installs glass, and training and authority are checked against the real role. | Better suited to people who want to work on timber structures and woodwork machining and installation; this occupation leans more towards glass, profiles, hoisting and sealing processes. |
|---|
| Drywall and Ceiling Tile Installers (47-2081.00) | Core work and outputs: set out and install framing, ceiling panels and gypsum board to drawings, treat joints and closures and inspect flatness and appearance; the outputs are ceiling and partition interior results. | Key difference: drywall and ceiling tile installers work with light steel framing, gypsum board, ceiling panels and partitions, including joint treatment, and their outputs are ceiling and partition interior results; this occupation works with glass (including at different sizes) and curtain wall and window nodes, and its outputs are glass installation results, and it normally does not carry conclusion responsibility for panel and framing system layouts or fire compartmentation (though it must coordinate with the fit-out and main contractor). | Better suited to people who want to install framing, panel ceilings and partitions and treat joints; this occupation leans more towards glass, profiles, hoisting, sealing, waterproofing and airtightness processes. |
|---|
| Sheet Metal Workers (47-2211.00) | Core work and outputs: lay out to drawings and shear, bend, seam or weld sheet metal, fabricate and install ducts and metal components and inspect; the outputs are sheet metal parts and installation results. | Key difference: sheet metal workers work with the layout, cutting, forming, joining and installation of sheet metal (including ducts and metal components), and their outputs are sheet metal parts and installation results; this occupation works with flat glass, profile frames and seals, and its outputs are glass installation results, and it normally does not carry conclusion responsibility for metal component load-bearing or duct system performance (though the two often need to coordinate on curtain wall metalwork and closures). | Better suited to people who want to work on sheet metal layout, forming and joining; this occupation leans more towards glass, profiles, sealing and hoisting processes. |
|---|
| Tile and Stone Setters (47-2044.00) | Core work and outputs: set out to drawings, prepare the substrate and lay tile or stone, level, grout, clean and inspect flatness and hollow spots; the outputs are unit paving results. | Key difference: tile and stone setters work with floor and wall units, bonding, levelling and grouting, and their outputs are unit paving results; this occupation works with facade and opening glass (including at different sizes), windows and doors and hoisting, and its outputs are glass installation results, and it normally does not carry conclusion responsibility for units, substrate bonding or waterproofing layers (though the two need to coordinate on waterproofing and closures in the same project). | Better suited to people who want to lay units, level and grout; this occupation leans more towards facade glass, profiles, hoisting and sealing processes. |
|---|
Compared by main material, task and outputs; occupation classification does not determine authority. Glazing covers building facades and interior tabletops and mirrors; vehicle glass is mainly vehicle windows, carpentry covers wood and similar material structures, and the other directions each require checking the added skills.
Transition | this page sets adjacent roles side by side by object and outputs and actual job duties and authorization, to help you judge which kind of building installation or component machining role you want to commit to long term. Whichever direction you choose, what really determines whether you can take the job is the object, process, codes, permits and qualification requirements of that direction, the ability to write measured values, deviations and acceptance records clearly, and the willingness to take responsibility for site safety and project quality; the interest questionnaire is only for raising questions.
Editorial ratings use the existing occupational responsibilities and AI task analysis on this page. They are not adoption rates, measured effects, job-disappearance or personal-unemployment probabilities, or official scores from Stanford or another external institution. No measured time weights or future robot deployment are assumed.
Technically feasible: a task may technically be reachable by a tool; this is only a feasibility judgment, it does not mean use is permitted, nor that an institution has adopted it.
Institutional and regulatory adoption: whether to introduce it depends on work-at-height, lifting and hoisting, transport, occupational health and product safety requirements and the institution's construction and quality systems; safety and quality responsibilities cannot shift because a tool is introduced.
The current BLS projection rounds to 2% growth and the direct table shows 1.9%, which is not an AI-caused increase or decrease or a guarantee for an individual job; the causality of role restructuring still needs evidence.

Task importance, context responses, advertised software mentions and AI exposure are different measurements. The O*NET detail page lists six software categories — CAD, work orders, Office, Windows, project management and Excel; the hot technologies page lists only Office and Excel with job-posting mentions each below 1% and Windows with an NA share, based on 2025 US Lightcast independent job advertisements. These are not on-site usage rates, AI adoption rates or productivity evidence.
Editorial AI trial comparison: drawings, lists and records can be explored with draft assistance, but no actual adoption rate or productivity gain for this occupation was verified; on-site measurement, process, safety, approval and acceptance follow the real duties and jurisdiction.
What AI mainly changesEditorial trial suggestion: check units, dimensions, versions and errors against the original drawings or lists and the tool-assisted version; no data showing that this occupation has adopted the tools or gained productivity was obtained.
Still the human's responsibilityOn-site plumb and dimensional measurement, cutting and grinding
What AI mainly changesInstallation, acceptance and deviation records, progress, quotations and training material drafts can be assisted by tools
Still the human's responsibilitySetting, fixing, caulking and sealing, and hoisting and rigging judgments
What AI mainly changesProject statistics, quality, cost and knowledge base material can be generated by tools
Still the human's responsibilityStructural safety, design changes, acceptance conclusions and external disclosure responsibility
Editorial trial responsibility note: assistance with drafts may be explored, but real responsibility and records must be kept for measurement, work, review and approval; no productivity gain for this occupation was verified.
Requirements and boundaries: drawings, specifications, codes, safety and work permits must be determined by personnel with the corresponding authorization; tools do not replace judgment on drawings, layout, work at height or hoisting.
On-site confirmation and quality: structural dimensions, embedded parts, openings, glass specifications, toughened and laminated markings and hoisting conditions must be checked by the individual against the codes; tools do not replace on-site measurement and verification.
Data and judgment: layout, measured values, deviations, installation and sealing data must be checked and reviewed by the individual; tool output must not be used directly as the basis for acceptance, rectification or external submission, and judgments must not exceed what the codes and data support.
Trial synthetic materials only in an environment where you have permission; trade secrets, copyright and identifiable personal information are checked separately, and not all drawings are treated as personal information.
Disclosure and change: glass specification and node adjustments, acceptance materials, external submission and process changes must take place within the scope of authorization and construction and quality requirements; when structures, specifications or conditions do not match, report per the system.
Tool drafts may contain unit or dimensional errors affecting cutting or installation.
Control method:Check the original drawing, units, version and real measurements before cutting or installing; do not deliver on the basis of a draft.
Misdirecting controlled materials, trade secrets or identifiable personal information exceeds authority.
Control method:Check authority, basis and necessity by type of material, and do not upload to unauthorized environments.
Text tools have not verified actual dimensions, plumb or on-site hoisting conditions.
Control method:Real measurements and on-site conditions are checked by trained personnel with the applicable qualifications or authorization.
Fabricated measurements and approvals destroy records and responsibility traceability.
Control method:Keep the original records and traceable corrections; fabricating measurements, backdating or approving is prohibited.
Unclear responsibility for measurement, work, review and approval hinders problem handling.
Control method:Clarify each role and the real records in advance; tools do not carry on-site authorization.
Use tools in reversible supporting steps: organizing drawings, work orders and layout data, organizing glass lists and batch ledgers, and drafting installation, acceptance and quotation records; on-site layout, cutting, hoisting and work at height follow the codes, mentoring and authorization.
Use digital tools for entering measured data, summarizing deviations, checking lists, and drafting records and repair orders; plumb, dimension, setting and sealing judgments remain the individual's own responsibility under the drawings and codes.
Use tools to consolidate multi-project data, deviation and rework trends, process knowledge bases and training materials; complex or controlled matters (mismatched structures or embedments, hoisting plan adjustments, concealed work and acceptance determinations) are confirmed by the individual together with the technical lead and quality roles.
Use tools for progress, quality and cost statistics, acceptance documentation, documentation and knowledge management; structural safety, design changes, acceptance conclusions and external disclosure must be human-approved with an audit trail.
This round cannot assert from existing materials whether it will or will not be replaced by AI; on-site work and record assistance are checked separately, and a trial creates no permit.

Judge with three layers of evidence: technical feasibility; institutional and regulatory adoption (depending on work-at-height, lifting and hoisting, transport, occupational health and product safety requirements); and job outcomes (this page uses this occupation's own 47-2121.00 measure). Combine local construction, curtain wall and window workload and retrofit and energy-saving demand and the supply of skilled installers rather than looking only at tool demonstrations.

| Educational background | Common role directions | Notes and verification suggestions |
|---|---|---|
| Education and training in construction, decoration, mechanical or materials related fields | Some roles | O*NET asks what education new entrants need; 44% answered a high school diploma or equivalent, 36% less than high school and 12% a postsecondary certificate; this is not the education already held by existing workers. Job Zone 1—2 and SVP below 6.0 are a general preparation description, not a uniform apprenticeship duration for this occupation. In the US, learning usually takes 3—4 years through an apprenticeship or on-the-job training, and most apprenticeship programmes require a high school equivalent and being at least 18 years old; some states require licensing, which is checked by specific state and cannot be used as a uniform mainland China entry requirement. |

Wage item | May 2025 BLS OEWS SOC47-2121 regular pre-tax wages, with national percentiles presented via O*NET; employment is separately the BLS2025 to 2035 projection, which includes self-employment while the wage series excludes it. The industry medians come from the BLS OOH2025 and are not the education questionnaire or the average of all industries.
Usage suggestion: read the median, percentile and employment figures together with the background that they use this occupation's own (47-2121.00) measure, do not represent adjacent occupations, and must not be mixed across the two projection periods, and check them against local industry and certification requirements; the official O*NET wage page can also be queried by region and period, and no single figure should be used to infer personal pay.

BLS notes that apprentice wages are lower than trained workers and rise with experience; national percentiles cannot be mapped item by item to seniority or used to infer the return on other factors.
Region verification suggestion: compare location, commuting and pay composition; national percentiles are not regional wages.
Skill verification suggestion: ask about the actual glass, frame and hoisting tasks and training; there is no income return estimate for individual skills.

Which Holland interest type is closer to glaziers?
Holland (RIASEC) | for understanding your relative position on Realistic and Conventional preferences. The O*NET interest code for this occupation is RC (Realistic—Conventional), corresponding to a willingness to handle, install and cut with hands, tools and equipment at height and on site (Realistic) and to execute according to blueprints, codes, tolerances and records (Conventional); this is consistent with the occupation's activity profile, which is dominated by inspecting equipment, structures or materials (84), getting information (82), handling and moving objects (79) and identifying objects, actions and events (77). The questionnaire is only for raising questions, not for judging suitability or fitness to work.
Do not use it like this:If you find it hard to face work at height, the outdoors, heavy lifting and cutting risk long term, or find it hard to accept schedule pressure and the constraints of transport and hoisting, a high interest questionnaire score cannot change that real cost; this occupation also requires confirming the institution's work-at-height, lifting and hoisting and occupational health protection and training requirements.
Test my Holland occupational interestsWhich Big Five traits are more relevant to this job?
The Big Five is only for self-questioning: whether you are willing to review units, record real problems and accept feedback; no particular score can be said to prove occupational fit.
Do not use it like this:Do not use a personality assessment saying I am not suited as a reason to give up or stay out of the field; rely instead on internships, shadowing, simulated layout and installation tasks, and mentor evaluations and assessment results.
See my Big Five personality traitsCan MBTI be used to judge whether I am suited to being a glazier?
MBTI | typology is used for self-reflection on communication and work preferences; this occupation requires communicating and coordinating with foremen, crews, the main contractor, the supervisor and the owner (face-to-face or in-person and team discussions 87% daily, continuous contact with others 55%), and preferences do not determine competence.
Do not use it like this:Treat the type only as a reference for communication style; do not use it to infer whether you or others can do installation at height, hoisting and sealing work well.
Understand my MBTI preferencesCan the Enneagram show whether I am suited to this occupation?
The Enneagram is used for self-questioning. Record how you check drawings, evidence and procedures when facing deviations, leaks or schedule pressure; the relative validity of task observation against type labels was not obtained, so which matters more is not judged.
Do not use it like this:Do not use type labels to explain quality defects or safety incidents; go back to whether drawings, codes, layout, hoisting and sealing were in place.
Explore my Enneagram patternCan I be a glazier if I am not good at math?
Observable learning performance this time in drawing reading, dimension and unit checking, cause verification and communication; the relative validity of IQ against these observations was not obtained, so it is not claimed that this occupation relies more on one of them, and real ability requires trained assessment.
Do not use it like this:A score level cannot show whether someone can learn layout, hoisting, sealing and cutting; this should be tested through internships, shadowing, simulated installation tasks and mentor evaluation.
Understand my intelligence and reasoning performanceDoes being a glazier require high emotional intelligence?
Emotion-related self-questioning: when out-of-tolerance results or disputes occur, can you clearly state what is known and unknown and ask for help per procedure; there is no predictive validity evidence for this occupation.
Do not use it like this:Do not limit yourself by assessment scores; after training, continue to observe actual communication and pressure handling, as this round obtained no effect of training in this occupation and improvement from work or practice is not guaranteed.
Understand my emotional intelligenceBetter match:Can independently complete layout, installation, sealing and hoisting coordination work within the scope of authorization and codes

Note:Editorial comparison note: check that direction's actual materials, tasks, training and job conditions; do not infer hiring, fit or transfer success from personality labels.
See related occupations:Tile and Stone Setter directionWhat kind of personality is better suited to being a glazier? This occupation values rigour about dimensions, plumb and sealing, adherence to work-at-height and hoisting safety procedures, stability and physical capacity under outdoor and schedule pressure, and a sense of responsibility for deviation and leak problems, rather than a particular personality type; the O*NET interest code is RC (Realistic—Conventional), which can serve as a starting point for exploration.
Actual collaboration is checked against the role. O*NET contact with others is 55% continually and 33% most of the time, with 87% face to face daily; this cannot be summarized as mainly independent work.
Introversion and extraversion are not used as an entry conclusion; observe whether the H1 handover distinguishes calculations, unknowns and items pending verification.
No evidence was obtained that a particular MBTI type is best for this occupation, and types are not used for hiring or qualification judgments; check skills, safety, training and authorization against the real role and do not claim they have been proven to determine fit.
Which Holland interest type is better suited to this occupation? The O*NET interest code is RC: Realistic (handling, installing and cutting with hands, tools and equipment at height and on site) and Conventional (executing according to blueprints, codes, tolerances and records); it can be used to explore task preferences, not to predict performance.
There is no personality or assessment predictive validity for this occupation, and general population trends are not used to infer performance in it.
Can someone who is bad at math do this occupation? It requires basic dimension, angle, area and quantity take-off and material quantity calculation and instrument reading ability; a quantitative foundation can be made up through training, but being wholly uncomfortable with readings, calculations and drawings would be a clear limitation.
Does this occupation require high emotional intelligence? It requires emotional stability, patience and crew and main contractor collaboration, but not a particular assessment score. Work at height, schedule pressure and rework disputes require self-regulation and communicating and reporting per procedure.
Can the Enneagram be used to judge whether I am suited? No. The Enneagram is a self-exploration tool and does not constitute a conclusion about occupational ability or fit; fit should be judged by whether one can complete layout, installation, hoisting and sealing work under safety and code requirements.
First complete the H1 paper area, joint width, missing permit and version checks, which only observe recalculation and traceable correction; they do not verify glass feel, real safety, qualifications or long-term fit.
Typical scenarios：Scenario | a high-level hoisting window is approaching, strong winds are forecast, the parties want to hoist first and fill in the protection and briefing records later, and the rigging and suction cups have not been inspected.
Main roles：The individual together with safety and hoisting roles; on-site personnel, property and third parties
Possible consequences：Inadequate protection at height, at edges and at openings, or unchecked harnesses, rigging, suction cups and lifting gear, or hoisting without a dedicated signaller, or overloading, or forcing work in bad weather; may cause fatalities and injuries, property loss and stoppage
Reducing risk：Before work, complete the safety briefing, risk assessment and inspection of tools, rigging and suction cups and correctly wear harnesses and protective equipment; set up a warning zone and a dedicated signaller for the hoisting area and stop immediately in bad weather or when conditions do not match; if protection, equipment or conditions are inadequate, stop immediately and report
Basis：O*NET tasks and context · Work Safety Law
Typical scenarios：Scenario | after installing a batch of curtain wall units, slight deviations and local signs of water seepage appear, the schedule is tight, and the site is asked to conceal them as conforming first and fill in the inspection and rectification records later.
Main roles：The individual together with technical and quality roles; the project, the owner and users
Possible consequences：Opening dimensions, embedded parts, plumb and layout deviations exceeding limits, or insecure frames, embedments and stops, or inadequate caulking, sealing and hardware, or unchecked glass specifications and toughened and laminated markings; may cause leaks, rework and structural or service safety risks
Reducing risk：Complete layout, measurement and installation to drawings and codes and control deviations within tolerance, install after verifying glass specifications, markings and appearance, and perform caulking, sealing and hardware to the process with concealed-work and acceptance records; process and acceptance records must be traceable and left alongside the work.
Basis：O*NET tasks and context · BLS Glaziers current occupational outlook (2025—2035)
Typical scenarios：Scenario | at handover, the previous shift's layout, measurement and concealed-work records are missing and the measured values do not match the records, and completing them from a template and signing later is suggested.
Main roles：The individual together with document and record roles; the institution, main contractor, supervisor and client
Possible consequences：Missing records, records inconsistent with measurements or untraceable alteration affect traceability; lawful correction must retain the original value, actual time, reason and review status and is not the same as falsification.
Reducing risk：Record truthfully; when errors are found, correct them with a trace and explain, and backdating, fabricating measurements or approving is prohibited; without review, keep the status as pending review.

Typical scenarios：Scenario | when staffing is tight, untrained personnel are asked to adjust glass specifications or nodes themselves, or to state conclusions about structural safety and acceptance conditions so they can be delivered the same day.
Main roles：The individual together with the technical lead and compliance roles; structural and acceptance conclusions
Possible consequences：Changing glass specifications, nodes or plans beyond authorization on one's own, or treating on-site results as confirmed conclusions in place of structural safety, curtain wall design changes, glass load-bearing calculations or acceptance conclusions; may give rise to quality, safety, compliance or legal liability
Reducing risk：Glass specification, node and plan changes must be approved per procedures with a trace, and structural safety, design verification, load-bearing calculations and acceptance conclusions are handed to the corresponding role or body; when faced with a request beyond authorization or for a conclusive statement, state the boundary first and hand over per the process.
Basis：O*NET tasks and context · Work Safety Law
Typical scenarios：Scenario | the only foreman familiar with a certain type of unitised curtain wall and hoisting process goes on vacation, and untrained personnel are asked to take over a key node temporarily.
Main roles：The individual together with crew and supply chain roles; schedule and construction continuity
Possible consequences：Key skills, lifting machinery and rigging, or supply and transport resting on a single point; vacation, resignation, equipment failure, supply delay or weather interrupting installation; may delay the schedule and affect quality consistency and safety redundancy
Reducing risk：Establish backup and handover rules for skills, equipment, rigging, materials and subcontractor resources so that key nodes and processes can be reproduced with a trace; when staff, equipment or materials are insufficient, report per the plan and adjust priorities rather than working with unaddressed hazards
Basis：O*NET tasks and context · NIST AI RMF
Typical scenarios：Scenario | after delivery or installation, a transport or subcontracting unit asks for settlement and handover without submitting specification, appearance, breakage and sealing inspection records, and the site is asked to sign first and supplement later.
Main roles：The individual together with subcontractors, transport and supply parties; quality, safety and responsibility
Possible consequences：Unclear delivery, acceptance, responsibility and cost-change terms for subcontracted installation, transport, incoming materials or hardware, or unclear responsibility for packaging, transport and storage of glass and curtain wall finished products; may lead to breakage, rework, cost disputes and unclear responsibility
Reducing risk：Subcontracting and cooperation must define scope, standards, acceptance, breakage liability, safety responsibility and cost-change rules with a trace, and incoming materials and deliverables must be reviewed and accepted; when delivery, breakage or ownership disputes arise, pause, review and report

Current verification on 2026-10-03: wages 2025 and projections 2025—2035, with the older O*NET period serving only as a version note. The Chinese legal sources already read in force are reused as real consultation, and it is not claimed that each was reread this round.
Sources by use: O*NET occupation descriptions, wages and software; the current BLS outlook and OEWS concepts; the AGMT, FGIA and NACC issuers; the Flynn employer requirement; and the Chinese legal sources that were read. Internal field rules are not treated as external evidence.
Usage limits：An occupation-level description that does not cover mainland China's construction safety, lifting and hoisting, special equipment and occupational health management systems.
Usage limits：BLS Occupational Outlook Handbook current 2025—2035: Glaziers 47-2121 employment 59,200 to 60,300 people, growth 2% (rounded in the Handbook), a net gain of 1,100 and an average of 3,900 openings per year; openings include growth and replacement and are not net gains or job advertisement counts. The direct projection table shows growth of 1.9% and employment including self-employment; the O*NET detail page still shows the older 2024—2034 figures of 60,500 people, 3% to 4% and 5,100 openings, and the older period serves only as a version note and is not mixed into the current indicators.

Usage limits：The 2025 US national wage for this occupation 47-2121 has a median of 57,080 USD per year and 27.44 USD per hour. OEWS includes production bonuses and commissions and excludes non-production bonuses, overtime premiums, shift differentials, benefits and self-employment; it is not total compensation or actual personal take-home pay. Percentiles are positions in the distribution and do not correspond to experience, qualifications or starting pay.
Usage limits：Insufficient evidence: the National Bureau of Statistics 2025 urban unit wage release read this round contains industry and five-category aggregation but does not provide national wage percentiles or employment scale precisely matching 47-2121.00; the legacy MOHRSS link is kept only as a search lead, and it is not asserted from unread text that no national statistics exist, nor are industry averages, job-posting offers or US figures substituted.
Usage limits：Only the legacy search entry is retained; the absence of national statistics for this occupation cannot be inferred from unread text, and it is not used as a wage proxy.
Usage limits：Articles 4/6/13/19; ordinary drawing dimensions are not automatically personal information.
Usage limits：Article 28 covers training and Article 30 provides for special operations, not a uniform glass certificate.
Usage limits：In force from 2026-08-15 with the old Environmental Protection Law repealed; Articles 80/150—151 are checked against the activity.
Usage limits：Articles 34—35 cover training and health examinations for those exposed to hazards, not the same medical examination for every role.
Usage limits：Articles 2/14/39—42/50—51; rigging and suction cups are not all catalogue items on the strength of their name.
Usage limits：Insufficient evidence: no precise mapping for this occupation was obtained; this is not an adoption or substitution rate.
Usage limits：Response category proportions, not every person's experience, an accident rate or a qualification.
Usage limits：Not construction safety, lifting and hoisting or product safety standards.
Usage limits：The 2025 US national wage for this occupation 47-2121 has a median of 57,080 USD per year and 27.44 USD per hour. OEWS includes production bonuses and commissions and excludes non-production bonuses, overtime premiums, shift differentials, benefits and self-employment; it is not total compensation or actual personal take-home pay. Percentiles are positions in the distribution and do not correspond to experience, qualifications or starting pay.
Usage limits：The O*NET detail page lists six software categories — CAD, work orders, Office, Windows, project management and Excel; the hot technologies page lists only Office and Excel with job-posting mentions each below 1% and Windows with an NA share, based on 2025 US Lightcast unique job advertisements. These are not on-site usage rates, AI adoption rates or productivity evidence.
Usage limits：Insufficient evidence: no complete job posting with an explicit posting date and pay was obtained; the requirements verified are at least 3—5 years of commercial glass experience and a valid driver's licence; the page has no explicit posting date or pay, so no hiring volume, representativeness or hiring outcome is inferred.
Usage limits：Certifications are checked by subject separately: AGMT targets experienced architectural glass installers and requires 7,500 hours of experience within 5 years, OSHA-10 or an equivalent Canadian requirement, and a written and practical test, with renewal every 4 years; FenestrationAssociate has no minimum education or experience, while Master requires meeting one of the issuer's three experience or education paths and completing the course and examination, and 19.5/23 hours are only the course running time; InstallationMasters covers new installation and replacement of windows and exterior glass doors for residential and light commercial use, and those with less than one year of installation experience are trainees; NACC certifies contracting firms, not individuals' installation qualifications. None of the above replaces government permits or employer authorization.
Usage limits：Installers and non-field professionals differ; less than one year of installation experience is a trainee, and this is not a uniform threshold for all curtain wall work.
Usage limits：An adjacent occupation measure, not equal to this occupation.
Usage limits：An adjacent occupation measure, not equal to this occupation.
Usage limits：Associate has no minimum education or experience; Master requires one of three conditions: 4 years of industry experience plus a PE or a specified four-year degree, 5 years plus one valid Associate year, or 6 years of industry experience; the course and examination are completed within December, with a 4-year certificate term.
Usage limits：It assesses firm capability and quality and safety methods; it is not an individual installer qualification or a government permit.
Usage limits：Construction72%, Retail13%, are employment shares; these are employment shares, not 2025 industry wages, and the periods must not be mixed.
Usage limits：An occupation description creates no design or acceptance authority, and measurement subjects are labelled separately.
Usage limits：Editorial ratings use the existing occupational responsibilities and AI task analysis on this page. They are not adoption rates, measured effects, job-disappearance or personal-unemployment probabilities, or official scores from Stanford or another external institution. No measured time weights or future robot deployment are assumed.
Insufficient evidence: no precise China occupational wage or employment mapping, no regional wage percentiles, no current complete recruitment posting with a date and pay, no generative AI adoption, substitution or income causality and no assessment occupational validity were obtained. The existing national and four-industry wages for this occupation are no longer counted as a gap; the editorial H1 and the path are not survey facts.

For mainland China, verify against the actual activity: Article 28 of the Work Safety Law covers training and Article 30 provides for special operation qualifications; Article 2 of the Special Equipment Safety Law covers the catalogue and Article 14 covers the qualifications of relevant personnel, while Articles 39—42 cover maintenance, inspection and handling of abnormal conditions, so ordinary rigging or suction cups are not automatically all listed in the catalogue on the strength of their name; statutory inspection is checked separately against Articles 50—51 on bodies and personnel. Articles 34—35 of the Occupational Disease Prevention and Control Law cover training and health examinations for those exposed to hazards. The Ecological Environment Code takes effect on 2026-08-15 and repeals the old Environmental Protection Law, and Articles 80/150—151 on monitoring authenticity, emissions and permits are checked against the activity. Articles 4/6/13/19 of the Personal Information Protection Law apply to identifiable personal information, and ordinary glass drawings, dimensions and coordinates are not automatically personal information. On-site protection, scaffolding, hoisting and construction conditions are checked against the real process and the applicable systems, and no nationwide uniform certificate is inferred from the occupation name.
| Adjacent object check: vehicle glass is checked by vehicle model; carpentry covers wood and similar material structures; 47-2042 is floor covering other than carpet, wood and hard tile and differs from 47-2044 tile and stone unit paving.

|---|
| Responsible party | Responsible party for this occupation | this occupation is responsible for the layout, measurement, installation, fixing, sealing and records that the individual performs, and for the work and verification completed according to blueprints, codes and safety requirements; matters involving structural safety, curtain wall design changes, glass load-bearing calculations, special equipment and hoisting plans and acceptance conclusions are decided by the role or body holding the corresponding qualifications according to the system, and this occupation does not replace their decisions. | Responsible party for adjacent roles | responsibility in the same and adjacent groups is usually defined by the employing institution together with codes and authorization, and the objects of responsibility are mostly construction safety, project quality, user safety and property. |
|---|
| Authority and approval | Authority and approval of this occupation | on-site work and work at height, at edges, at openings, hoisting, temporary electrical supply and transport must take place within the scope of safety technical measures, the dedicated plan and authorization; glass specification changes and curtain wall and window node adjustments must be approved per procedures; concealed work, acceptance and rectification must follow the quality system and authorization; matters involving structural safety, curtain wall design changes, glass load-bearing, special equipment and hoisting plans, and environmental protection and occupational health must obtain the corresponding job or institutional approval or be handed over per the system, and no operation or conclusion may exceed authority. | Authority and approval of adjacent roles | authority in the same and adjacent groups comes from institutional authorization, codes, qualifications and systems and usually does not include the authority to decide on conclusions, signatures or data provision beyond one's own authorization or scope; matters involving structural changes, design verification, inspection, compliance and personal information should be handed to the corresponding role or body. |
|---|
| Conclusion boundaries | Conclusion boundaries of this occupation | work conclusions state only verifiable layout, measurement, installation, sealing and acceptance records, and distinguish on-site measured facts from judgments, inferences and items pending verification; no unauthorized judgment or promise may be made on matters beyond the individual's authorization (structural safety, curtain wall design changes, glass load-bearing calculations, acceptance conclusions); when structures or embedded parts do not match, or glass specifications do not match, or hoisting and protection conditions are inadequate, or deviations exceed limits, or records conflict with the site, work must stop and be escalated or handed over, and conclusions must also withstand review by supervisors and by the main contractor, supervisor and competent authority. | Conclusion boundaries of adjacent roles | conclusions in the same and adjacent groups are mostly limited to the project, process and duty in question and usually do not constitute a determination of structural safety, compliance or legal liability; conclusions that cross disciplines or are used for engineering, inspection or legal purposes have limits on their applicability. |
|---|
Verification point notes | this occupation often involves work at height, at edges and at openings, hoisting, heavy lifting, glass cutting, the outdoors and noise, and usually requires work-at-height, lifting and hoisting, construction safety and occupational health training, protective equipment, work permits and emergency drill requirements.
O*NET asks what education new entrants need; 44% answered a high school diploma or equivalent, 36% less than high school and 12% a postsecondary certificate; this is not the education already held by existing workers. Job Zone 1—2 and SVP below 6.0 are a general preparation description, not a uniform apprenticeship duration for this occupation. In the US, learning usually takes 3—4 years through an apprenticeship or on-the-job training, and most apprenticeship programmes require a high school equivalent and being at least 18 years old; some states require licensing, which is checked by specific state and cannot be used as a uniform mainland China entry requirement.
Contract review suggestion: ask about base pay, production and non-production bonuses, overtime and shift differentials, benefits, hours, training, travel and weather stoppage arrangements; these are items to ask about, and it is not proven that all roles have them.
Verification point notes | the interfaces with the main contractor, supervisor, technical lead, safety and supply chain parties determine the boundaries of work, records and responsibility and must be clarified in advance.
Verification point notes | the traceability and audit-trail requirements for layout, measurement, glass specifications, installation, sealing, hardware, concealed work, acceptance and training records determine how quality, safety and responsibility are defined, and the templates, time limits, modification, archiving, access and retention rules must be clarified in advance (data that is controlled or involves trade secrets, drawings, client information or personal information must also be managed under confidentiality and minimum-necessary requirements).
Matters involving structural safety, curtain wall design changes, glass load-bearing calculations, special equipment and hoisting plans and acceptance conclusions must be performed by the role or body holding the corresponding qualifications.
The retention, provision and disclosure of controlled materials, or materials involving trade secrets, drawings, client information or personal information, must be managed under confidentiality and minimum-necessary requirements; controlled materials must not be sent to unauthorized environments.
The work context (percentage response basis) shows using hands to handle, control or feel objects, tools or controls 82% continually or almost continually, face-to-face or in-person and team discussions 87% daily, wearing common protective or safety equipment 74% daily, being outdoors exposed to all weather 54% daily, standing 61% continually or almost continually, and importance of being exact or accurate 49% extremely important.
The interest and work context data are only for self-questioning and do not constitute hiring or performance conclusions.
Judgments about dimensions, plumb, sealing and hoisting safety depend on professional knowledge, experience and on-site confirmation, while digital tools are used for drawings, lists, records and document management.
Authority over glass specification changes, node adjustments, acceptance and disclosure follows institutional authorization and codes and quality requirements; tools and software do not produce authorization.
Reference issues table: C and D exceed the teaching dimensional limits; the blank scaffolding inspection, the unapproved hoisting and the missing post approval for the person remain unknown or unapproved. No glass specification, material, calibration, wind load or real approval standard was given, so construction qualification or safety cannot be judged.
V1 to V2 reference: 1,920,000 square metres to 1.92 square metres (converting square millimetres to square metres by dividing by 1,000,000); all four joints conforming to only A and B being within limits; retain the original value, actual time and reason, with S pending review, and no backdating or fabricated approval.
Time and cost reference: 11:15 − 10:47 = 28 minutes; 10:47 − 10:29 = 18 minutes. Glass 520 CNY + labour 225 CNY + seal strip 105.60 CNY = 850.60 CNY. Handover example: verified area 1.92 m², perimeter 8 m and teaching allowance 8.8 m; C and D exceed the limits by 0.5 mm. Permit and inspection items are missing, V2 is pending review, Q has waited 18 minutes and there are 28 minutes to handover. The subtotal of 850.60 CNY is not a quotation and no on-site work was performed.
The work sample only shows unit recalculation, evidence stratification, traceable correction and handover; it cannot prove product acceptance, hands-on work, safety competence, qualifications or occupational fit.

Articles 4/6/13/19 of the Personal Information Protection Law apply to identifiable personal information, and ordinary glass drawings, dimensions and coordinates are not automatically personal information. On-site protection, scaffolding, hoisting and construction conditions are checked against the real process and the applicable systems, and no nationwide uniform certificate is inferred from the occupation name. | According to the actual activity and jurisdiction | Training and specified special operation qualifications are checked separately | No specific programme duration or cost was verified | Not a uniform certificate for all rigging or suction cups |
|---|
| Industry certification subjects are checked separately | Installing individuals, window and door professionals and contracting firms | Certifications are checked by subject separately: AGMT targets experienced architectural glass installers and requires 7,500 hours of experience within 5 years, OSHA-10 or an equivalent Canadian requirement, and a written and practical test, with renewal every 4 years; FenestrationAssociate has no minimum education or experience, while Master requires meeting one of the issuer's three experience or education paths and completing the course and examination, and 19.5/23 hours are only the course running time; InstallationMasters covers new installation and replacement of windows and exterior glass doors for residential and light commercial use, and those with less than one year of installation experience are trainees; NACC certifies contracting firms, not individuals' installation qualifications. None of the above replaces government permits or employer authorization. | According to the target programme; the catalogue does not set a general threshold | AGMT, FGIA, InstallationMasters and NACC conditions differ | Course duration is not the certification cycle; check the issuer for specific enrolment | NACC is for firms and cannot serve as an individual certificate |
|---|
