Almost no workplace is fully exempt from OSHA's Hazard Communication Standard. Under 29 CFR 1910.1200(b), the standard applies to any chemical known to be present in the workplace in a way that employees may be exposed under normal conditions of use or in a foreseeable emergency. What 1910.1200(b) actually does is create three tiers: fully covered workplaces (most manufacturing, construction, salons, shops and healthcare), partially covered workplaces (laboratories under 1910.1200(b)(3) and sealed-container operations under 1910.1200(b)(4)), and a narrow list of exempted substances and articles under 1910.1200(b)(5) and (b)(6) — such as hazardous waste regulated by RCRA, tobacco, wood products, food and drugs for personal consumption, and manufactured articles that don't release a hazardous chemical.
The distinction that trips people up: the exemptions in paragraph (b) are mostly substance-based, not workplace-based. "We're just an office" is not a defense if there's a gallon of floor stripper in the janitor's closet and an employee handles it.
The three tiers at a glance
| Setting | Status under 1910.1200(b) | What's required |
|---|---|---|
| Manufacturing, shops, salons, cleaning crews, healthcare with chemical handling | Fully covered | Written program, labels, SDSs, chemical inventory, training per (h) |
| Laboratories meeting the (b)(3) definition | Partially covered | Keep incoming labels intact, maintain and provide access to SDSs, train per (h); also 1910.1450 Lab Standard |
| Sealed containers never opened on site, (b)(4) | Partially covered | Labels intact, SDSs on request and when received, training on hazards from leaks/spills |
| Office with only consumer-quantity products used as a consumer would | Effectively out of scope for those products | No SDS/label duties for those specific items — but duration/frequency test applies |
| Hazardous waste (RCRA), tobacco, food, drugs for personal consumption, articles | Exempt substances | No HazCom duties for those items specifically |
| Construction sites | Fully covered via 29 CFR 1926.59 | 1926.59 adopts 1910.1200 in its entirety; multi-employer rules apply |
Laboratories: partially covered, not exempt
A "laboratory" under 1910.1200(c) means a facility where relatively small quantities of hazardous chemicals are used on a non-production basis. If you meet that definition, 1910.1200(b)(3) limits your HazCom duties to three things:
- Ensure labels on incoming containers of hazardous chemicals are not removed or defaced.
- Maintain any safety data sheet received with incoming shipments and ensure it is readily accessible to lab employees during each work shift.
- Provide employees with information and training per paragraph (h).
Note what is not required: a written hazard communication program covering lab operations. But labs are separately governed by the Occupational Exposure to Hazardous Chemicals in Laboratories standard, 29 CFR 1910.1450, which requires a Chemical Hygiene Plan, a designated Chemical Hygiene Officer, and annual review. Labs that also ship chemicals out of the lab lose the (b)(3) break for that activity and must comply as a distributor.
Pilot plants and production labs
If your "lab" is producing material for commercial sale — a pilot plant, a quality-control line running production batches — OSHA treats it as a production operation. Full 1910.1200 coverage applies, including the written program under (e).
Sealed-container warehouses and retail
Paragraph (b)(4) covers operations where chemicals arrive in sealed containers and are not opened under normal conditions of use — classic distribution warehouses, freight terminals and many retail stockrooms. You must:
- Keep incoming labels on sealed containers intact and legible.
- Maintain SDSs received with shipments and provide them to employees on request.
- Obtain an SDS as soon as possible if an employee requests one you don't have.
- Train employees per (h) on hazards they could face from spills, leaks or ruptures — the foreseeable-emergency scenario.
The exemption evaporates the moment a container is opened on site. Breaking a drum to repackage, opening a case to sample, or decanting into a spray bottle moves that operation into full coverage — including secondary container labeling under (f)(6). Warehouses also tend to stack other exposures on top: forklift traffic, racking, and chemical drums in the same aisle. If your crew runs powered industrial trucks around hazardous materials, pair HazCom with Forklift Safety (Theory) so the hazard picture is complete.
Salons, barbershops and body art studios: fully covered
Salons are one of the most commonly misclassified workplaces. Hair color developers, bleach powders (persulfates), relaxers, acrylic monomers, disinfectants and formaldehyde-releasing smoothing treatments are all hazardous chemicals, used repeatedly, in quantities and frequencies well beyond consumer use. That means a written hazard communication program under 1910.1200(e), a chemical list, accessible SDSs, labeled mixing bowls and spray bottles, and documented training.
The consumer-product argument generally fails here. OSHA's position is that an exemption applies only when employee exposure duration and frequency are not greater than what a typical consumer would experience. A stylist mixing color for eight hours a day is not a typical consumer. Tattoo and piercing studios face the same analysis, and also have a separate Bloodborne Pathogens (Body Art & Tattoo) obligation under 1910.1030.
Offices: it depends entirely on what's in the closet
An office where employees use toner cartridges, correction fluid and a can of disinfectant spray the way a household would is effectively outside HazCom for those products — OSHA has said office workers who encounter hazardous chemicals only in isolated instances are not covered. But coverage attaches if:
- You employ janitorial or maintenance staff who use industrial-strength cleaners, floor finishes or drain openers.
- You have a print shop, shop area, generator, or chemical storage room.
- Anyone handles bulk quantities rather than retail packaging.
In those cases, the cleaners are covered, and the employees who use them need training. The rest of the office staff may not.
Construction sites: no separate exemption
Construction employers are covered by 29 CFR 1926.59, which states plainly that the requirements of 1910.1200 apply. There is no construction carve-out. The practical complications are multi-employer: on a shared site, each employer must inform other employers of hazardous chemicals they bring on site, the labeling system used, and where SDSs can be accessed — typically addressed through the GC's site-specific program.
Common construction chemicals that require coverage include silica-containing products, epoxies, solvents, curing compounds, adhesives, fuels and welding consumables. Where exposure controls involve respirators, HazCom training does not substitute for the medical evaluation and fit testing required by 1910.134; see Respiratory Protection for that side of the program.
The "article" exemption — and its limits
Under 1910.1200(c), an article is a manufactured item that has a specific shape or design, whose function depends on that shape, and that does not release more than trace amounts of a hazardous chemical under normal use. A steel beam sitting in a yard is an article. That same beam being cut, welded or ground releases metal fume — at which point the exemption no longer covers the operation. Lead-acid batteries, treated lumber being sawn, and brake pads being machined follow the same logic.
Frequently asked questions
Does an online HazCom course satisfy OSHA's training requirement?
Not by itself. Paragraph (h) requires training on the specific hazardous chemicals in your work area, where your written program and SDSs are kept, your labeling system, and the detection methods and protective measures used at your site. Online training covers the GHS framework, pictograms, label elements and SDS sections; the employer must add documented site-specific instruction on its own chemical inventory. Our Hazard Communication (GHS) course is built to handle the general component so your supervisors only need to cover the site-specific piece.
How often is HazCom retraining required?
OSHA sets no fixed annual interval in 1910.1200(h). Training is required at initial assignment and whenever a new chemical hazard is introduced into the work area. Most employers retrain annually as a practical refresher and to document ongoing competence; some state plans and contracts impose their own annual requirement.
Do we need SDSs for hazardous waste?
Hazardous waste as defined by RCRA and regulated by EPA is exempt under 1910.1200(b)(6)(i), as is hazardous substance released and regulated under CERCLA. That exemption does not extend to the chemical before it becomes waste, and it does not relieve you of other OSHA duties such as HAZWOPER where applicable.
Are drugs and cosmetics in a healthcare setting exempt?
Only in narrow circumstances. Drugs in solid final form for direct administration to a patient (tablets, pills) are exempt, as are drugs intended for personal consumption by employees. Compounding, crushing tablets, or handling hazardous drugs in liquid or powder form is covered, and NIOSH hazardous-drug handling expectations apply on top of HazCom.
