HazCom Compliance, by Industry
Every sector handles different chemicals and faces different OSHA enforcement priorities — construction trades under 29 CFR 1926 and general industry under 1910. Pick yours to see the specific hazards, the citations inspectors write most, and what HazComFast puts on your crew's phones for each one.
One standard, many rulebooks: HazCom (1910.1200) is OSHA’s #2 most-cited standard (FY2025), but the chemicals, exposure limits, and citation part number change with the trade. Pick yours below.
Why hazard communication is trade-specific
Hazard Communication (29 CFR 1910.1200, adopted for construction by 1926.59) is the same standard for everyone — but the chemicals, the exposure limits, and the OSHA enforcement priorities are not. A concrete crew's biggest risk is respirable silica; an electrical crew's is energized equipment and dielectric fluids; a painter's is isocyanates and solvents.
HazCom itself is OSHA's #2 most-cited standard, and on a shared jobsite the Multi-Employer Citation Policy means one trade's unlabeled container can cite several employers at once. Pick your sector below for the specific chemicals, citations, and controls.
The sector also decides which rulebook applies. Construction trades answer to 29 CFR 1926; general industry — manufacturing, warehousing, and fixed facilities — answers to 29 CFR 1910, with a Subpart Z Table limit for hundreds of chemicals plus stricter, expanded substance-specific standards. The citation an inspector writes carries the matching part number.
What OSHA actually cites in construction (FY2025)
Federal OSHA's ten most-cited construction (NAICS 23) standards, with the real citation counts and penalties (current amounts) — and which trades each one typically lands on. Five of the ten are fall-related; Hazard Communication is the one standard that reaches every trade on this page.
| Standard | Citations | Penalties (current) | Trades typically exposed |
|---|---|---|---|
| 1926.501 Duty to have fall protection | 6,772 | $44.9M | Roofing, framing, concrete decks — any work at 6 ft |
| 1926.1053 Ladders | 2,758 | $9.6M | Every trade that climbs — HVAC, electrical, painting |
| 1926.503 Training requirements (fall protection) | 2,171 | $4.6M | Same crews as 1926.501 — the training half of the duty |
| 1926.451 Scaffolds — general requirements | 2,152 | $7.6M | Masonry, concrete, painting, plaster — supported scaffolds |
| 1926.102 Eye and face protection | 1,926 | $6.6M | Welding, concrete (splash), demolition — eye and face |
| 1926.20 General safety and health provisions | 866 | $3.5M | All trades — the accident-prevention program duty |
| 1926.100 Head protection | 852 | $2.6M | All trades — head protection where overhead work exists |
| 1903.19 Abatement verification | 805 | $0.3M | Any employer with a prior citation — abatement proof |
| 1910.1200 Hazard Communication | 698 | $1M | Every trade — chemicals cross all of them |
| 1926.502 Fall protection systems criteria and practices | 665 | $2.1M | Same fall-protection systems — criteria and practices |

1926 vs 1910 — what changes when the rulebook changes
The same chemical can sit under two different rulebooks depending on where it is used. HazCom itself is identical — construction adopts 29 CFR 1910.1200 verbatim through 1926.59 — but almost everything wrapped around it differs:
| Requirement | Construction (29 CFR 1926) | General industry (29 CFR 1910) |
|---|---|---|
| HazCom | 1926.59 — adopts 1910.1200 unchanged | 1910.1200 directly |
| Air-contaminant limits | 1926.55 (Tables 1 and 2) | 1910.1000 Subpart Z Tables Z-1 / Z-2 / Z-3 |
| Silica | 1926.1153 — Table 1 task controls | 1910.1053 — action-level monitoring path |
| Inspections | 1926.20(b)(2) — frequent & regular, by a competent person | Per-standard (e.g., 1910.147(c)(6), 1910.134(h)) |
| Emergency plans | 1926.35 — when a standard requires one | 1910.38 — same trigger, same elements |
| Typical citation reads | 1926.501, 1926.1053, 1926.451… | 1910.1200, 1910.147, 1910.134… |
A crew that does both — a mechanical contractor fabricating in the shop (1910) and installing on site (1926) — owes both rulebooks; the written HazCom program is the one document that carries across.
Choose Your Industry
Sector-specific HazCom guidance for the trades and industries we serve.
Construction Trades
Field crews under 29 CFR 1926 — the hazard changes with the trade.
Concrete Contractors
Crystalline silica is OSHA's #1 construction enforcement priority. Table 1 compliance, admixture SDS, and alkaline burn first aid on every pour.
Demolition Contractors
Lead, asbestos, silica, and unknown legacy chemicals. Pre-demo surveys and SDS access for the hazards hidden inside every structure.
Electrical Contractors
Solvents, cleaners, PCBs in old transformers, and cable-pulling lubricants. Digital SDS and LOTO documentation for the field.
HVAC Contractors
Refrigerants, brazing fluxes, coil cleaners, and sealants. SDS and GHS labels for techs working across dozens of sites a week.

Laboratories
Governed by the Laboratory Standard (1910.1450) and a Chemical Hygiene Plan, not plain HazCom. Formaldehyde, ethylene oxide, and solvents controlled at the fume hood.
Auto Repair
Solvents, legacy brake asbestos, lead, isocyanate paint, and engine exhaust — five serious hazards in one bay. SDS and controls for the whole shop.
Janitorial & Facilities
Almost pure HazCom — and the mixing trap: bleach with ammonia or acid makes toxic gas. Secondary-container labels and SDS on the cart.
Food & Beverage
Ammonia refrigeration (PSM at 10,000 lb), CIP caustics and acids, chlorine and peracetic sanitizers, and CO2 in tanks and cellars.
Warehousing & Distribution
The charging station is the chemical program: hydrogen off the cells, sulfuric acid in them, and carbon monoxide from the propane truck beside them.
Building Maintenance
Mechanical-room chemistry — chlorine, caustic, acid — plus the asbestos and lead a pre-1980 building puts in reach of a routine repair.
HazCom by industry — FAQ
Why is HazCom different for each trade or sector?
Every trade and industry brings different chemicals and faces different OSHA enforcement priorities — respirable silica for concrete, lead and asbestos for demolition, refrigerants for HVAC, and the widest chemical variety of all in manufacturing. Your written program, labels, SDSs, and training must reflect the specific chemicals your team actually handles.
What's the difference between construction and general-industry HazCom?
The Hazard Communication standard is the same, but the surrounding rulebook differs. Construction trades work under 29 CFR 1926 (HazCom adopted by 1926.59); general industry — manufacturing, warehousing, fixed facilities — works under 29 CFR 1910, which adds a Subpart Z Table Z limit for hundreds of air contaminants plus expanded substance-specific standards (lead, hexavalent chromium, methylene chloride, formaldehyde, and more), each with its own monitoring and medical surveillance. The citation an inspector writes carries the matching part number.
Does every contractor need a written HazCom program?
Yes. Any employer whose employees may be exposed to a hazardous chemical under normal conditions or in a foreseeable emergency must have a written Hazard Communication program (29 CFR 1910.1200(e); construction 1926.59) covering labels, SDSs, training, and the chemical inventory.
Which OSHA standards do the trades get cited for most?
Fall Protection (1926.501) is OSHA's #1 most-cited standard, Hazard Communication (1910.1200) is #2, Ladders (1926.1053) is #3, and Control of Hazardous Energy / LOTO (1910.147) is #4 (FY2025). Five of the ten most-cited standards are construction standards, so most trades meet several at once.
Who is liable for chemicals on a shared multi-employer jobsite?
Under OSHA's Multi-Employer Citation Policy (CPL 02-00-124), OSHA can cite the creating, exposing, correcting, or controlling employer for the same hazard — so a subcontractor's unlabeled container can put the general contractor at risk too.
Get the Binder in Order Before the Inspector Arrives. Are You Ready?
OSHA does not give advance notice of inspections (29 CFR 1903.6). Get the binder in order before the opening conference, not during it.
