OSHA 1910 vs 1926: which standard applies to your workers?

Last updated 2026-07-11

What is 29 CFR 1910 and who does it cover?

29 CFR Part 1910 is OSHA's general industry standard. It applies to any workplace that isn't agriculture, maritime, or construction. Manufacturing plants. Warehouses. Restaurants, retail stores, hospitals, printing shops, auto repair bays, offices. ^[1]

The standard runs across dozens of subparts, each aimed at a specific hazard category. Subpart D covers walking-working surfaces. Subpart H covers hazardous materials. Subpart J covers general environmental controls, Subpart O covers machinery and machine guarding, and it goes on from there. When people talk about OSHA compliance in most small businesses, they're almost always talking about 1910.

Here's the part that trips people up. Your company's industry code (NAICS or SIC) doesn't decide which standard applies. What decides it is what your workers are physically doing on a given day.

What is 29 CFR 1926 and who does it cover?

29 CFR Part 1926 is OSHA's construction standard. It covers employers and employees engaged in construction work, which OSHA defines in 29 CFR 1926.32(g) as "construction, alteration, and/or repair, including painting and decorating." ^[2]

Part 1926 has its own subparts that mirror many general industry topics but with construction-specific rules. Subpart C covers general safety and health provisions. Subpart K covers electrical, Subpart L covers scaffolds, Subpart M covers fall protection, Subpart R covers steel erection.

The construction standard grew partly out of the Construction Safety Act of 1969, which predates the OSH Act itself. OSHA folded those requirements in and has built on them ever since. ^[3]

Roofing company, plumbing contractor, concrete crew, general contractor: 1926 is your primary rulebook. The OSHA 30 training courses for construction workers are built around 1926 topics for exactly this reason.

How do you know which standard applies to a specific worker?

The test is activity-based, not employer-based. OSHA has said in multiple letters of interpretation that the answer follows the work being performed, not the employer's primary business classification. ^[4]

The practical rule: if a worker is doing construction work (building, altering, or repairing a structure), 1926 applies to that work. If the same worker is back in the shop maintaining equipment or moving pallets in the warehouse, 1910 applies to that activity.

A hospital facilities manager who hires outside contractors to renovate a wing is still a general industry employer under 1910. The contractors doing the renovation are under 1926. The hospital's own maintenance staff doing minor drywall repairs in that same building? That's the gray zone. OSHA has indicated that maintenance work that is "minor" and "incidental" to general industry operations falls under 1910, not 1926, but the line is genuinely blurry and has been litigated more than once. ^[4]

The cleanest mental model I use: ask whether the end product of the work is a structure or a change to a structure. If yes, 1926 probably applies.

What happens when both standards seem to apply at the same time?

When your employees are doing construction work, 1926 controls. When they're doing general industry work, 1910 controls. That much is simple. The confusion starts when both happen on the same site during the same shift.

OSHA's position, stated in letters of interpretation, is that each standard applies to the operations and hazards it was written to address. ^[4] If a manufacturing plant shuts down a production line to rebuild it, the renovation crew works under 1926 even if the same company signs their checks. The workers keeping the other lines running during that shutdown work under 1910.

There's a second wrinkle. Some 1910 standards apply directly to construction employers. 1910.1200, the hazard communication standard (HazCom/GHS), applies to general industry and construction alike. ^[5] 29 CFR 1926.59 adopts 1910.1200 by reference, so the requirements are word for word identical. Some lockout/tagout requirements work the same way.

Third wrinkle. Where no 1926 standard covers a specific hazard that construction workers face, OSHA can cite the construction employer under the General Duty Clause (Section 5(a)(1) of the OSH Act) or, in some cases, under 1910. OSHA has done exactly this with ergonomic hazards and certain chemical exposures.

Which standard covers mixed-use employers, like contractors who also do maintenance?

Specialty contractors who split their time between building things and maintaining equipment (HVAC contractors, elevator mechanics, utility crews) hit this question constantly. The character of the work at any given moment controls.

An HVAC tech installing a new commercial unit in a building under construction is doing construction work under 1926. The same tech running a routine maintenance call on an existing system in an occupied building is doing general industry work under 1910. ^[4] Same person, same truck, two different standards depending on the day.

So some contractors need written safety programs that address both standards. Their OSHA training has to cover both, which is why OSHA 30 training exists in a construction version and a general industry version. Different courses, different content, different focus. Don't send your construction crew to the general industry OSHA 30 and assume you're covered.

If your workers regularly do both kinds of work, the honest answer is you need a safety program built for both. That's more work. It's also the only defensible position when OSHA shows up.

What are the most important differences between 1910 and 1926 on specific topics?

The two standards often handle the same hazard differently because the physical environments differ. A fixed manufacturing platform isn't the same risk as a jobsite scaffold going up in a week.

Topic	1910 (General Industry)	1926 (Construction)
Fall protection trigger height	4 feet (walking/working surfaces, 1910.28) [6]	6 feet for most tasks (1926.502) [7]
Scaffolding	1910.28 (general; limited detail)	1926 Subpart L (detailed scaffold types, load ratings)
Electrical safety	1910 Subpart S	1926 Subpart K
Hazard communication	1910.1200 (direct requirement)	1926.59 (adopts 1910.1200 by reference)
Lockout/tagout	1910.147 (direct requirement)	No equivalent in 1926; OSHA uses 1910.147 via General Duty or 1926.417 for electrical
Forklift safety	1910.178 (powered industrial trucks) [8]	1926.602 (construction vehicles; different standard)
Personal protective equipment	1910 Subpart I	1926 Subpart E
Recordkeeping	29 CFR Part 1904 (applies to both)	29 CFR Part 1904 (same)

The fall protection height gap is the single most consequential practical difference. A 5-foot work platform in a warehouse requires fall protection under 1910 because it's at or above the 4-foot threshold. The same 5-foot height on a construction site triggers nothing, because 1926 sets the line at 6 feet. That one number changes how OSHA writes the citation.

Forklift certification is another spot where employers mix up the standards. Forklifts in warehouses and manufacturing fall under 1910.178. Construction forklifts fall under 1926.602. The training requirements and equipment specs are not the same.

Does 1926 apply to temporary workers or staffing agency employees on a construction site?

Yes. The standard follows the work, not the paycheck. A temp placed by a staffing agency who is doing construction work on a jobsite is covered by 1926. ^[1]

OSHA's multi-employer worksite policy matters here too. Under that policy, OSHA can cite the creating employer (the one that made the hazard), the exposing employer (the one whose people face it), the correcting employer, and the controlling employer. A general contractor can be cited for a hazard a subcontractor's crew created, and the reverse happens too. ^[9]

Staffing agencies and host employers share the duty for temp worker safety. The host controls the day-to-day work conditions and usually handles site-specific training. The staffing agency has a continuing obligation to place workers in safe conditions and make sure they know the hazards. Neither one gets to fully hand off the responsibility.

What about state OSHA plans: do they follow the same 1910 and 1926 structure?

Mostly yes, but not always to the letter. Twenty-nine states and territories run their own OSHA-approved state plans. ^[10] Each plan has to be "at least as effective" as federal OSHA, which in practice means it adopts the federal structure (1910 for general industry, 1926 for construction) and then can stack stricter rules on top.

California's Cal/OSHA is the best-known example. Cal/OSHA uses Title 8 of the California Code of Regulations instead of CFR numbering, but the general industry versus construction split is the same. Cal/OSHA also carries extra requirements in areas like heat illness prevention and silica that go past the federal floor. ^[10]

Washington (L&I), Michigan (MIOSHA), and North Carolina (NC OSH) all follow the same structural split while carrying their own specific standards that can differ. In a state plan state, check your state agency's site on top of federal OSHA. Don't assume the federal rule is the whole story.

What are the most common OSHA violations under each standard?

OSHA publishes its top 10 most frequently cited standards every fiscal year. ^[11] For fiscal year 2023, the leaders looked like this.

1926 (Construction) top citations: 1. 1926.501: Fall protection (scaffolding, roofing, leading edges) 2. 1926.1053: Ladders 3. 1926.503: Fall protection training 4. 1926.20: General safety and health provisions 5. 1926.451: Scaffolding

1910 (General Industry) top citations: 1. 1910.1200: Hazard communication 2. 1910.134: Respiratory protection 3. 1910.147: Control of hazardous energy (lockout/tagout) 4. 1910.212: Machine guarding 5. 1910.178: Powered industrial trucks (forklifts)

Fall protection tops the 1926 list year after year, and that's no accident. Falls are the leading cause of construction fatalities. The Bureau of Labor Statistics reported that in 2022, falls, slips, and trips accounted for 395 of 1,069 total construction fatalities, about 37 percent. ^[12]

Knowing the top violations under your standard pays off when you build a program or run a self-audit. If you're in general industry and you don't have a written hazard communication program, you're statistically the most likely person in the room to get cited.

Do I need a written safety program under 1910, 1926, or both?

Both standards require written programs for specific hazards, and being small doesn't get you out of it.

Under 1910, written programs are required for hazard communication (1910.1200(e)), respiratory protection (1910.134(c)), lockout/tagout (1910.147(c)(1)), hearing conservation (1910.95), bloodborne pathogens (1910.1030), and emergency action plans (1910.38), among others. ^[5]

Under 1926, written programs are required for hazard communication (via 1926.59 adopting 1910.1200), excavation safety plans (1926.652), fall protection plans (1926.502(k) for certain work), and confined space entry (1926.1204), among others.

Here's the honest reality for small employers. Most of them are missing at least two or three required written programs and don't know it. That's not a judgment, it's just what small business citation data shows. If you're building these from scratch and don't want to pay a consultant, a tool like SafetyFolio's safety program generator gets you to a compliant first draft in a fraction of the time a blank page takes. The incident report process is another place where small employers run informal practices that miss the 29 CFR Part 1904 recordkeeping requirements, which apply under both standards.

What if OSHA cites me under the wrong standard?

It happens more than you'd think. If OSHA cites you under 1910 for work that was clearly construction under 1926 (or the reverse), that's a real basis for contesting the citation. The citation has to name the correct standard for the specific hazard and work activity.

You have 15 working days from receipt of the citation to file a notice of contest. ^[1] If you think the wrong standard was cited, build your record: what the work actually was, what standard should apply, and why the cited standard doesn't fit.

One caveat. If the underlying hazard is real and the penalty is your main worry, an informal settlement with OSHA's area director is often faster and cheaper than a formal contest. Area directors have discretion to cut penalties and adjust citations in informal conferences. Have that conversation before you decide to fight.

How do you build a safety program when both standards apply to your company?

The method is the same as a single-standard company, just wider. Map every job task your workers do, then match each task to the standard that governs it. Task-by-task beats picking one standard and hoping it stretches to cover everything, and it holds up better if OSHA questions it.

For a company doing both maintenance and construction, your written program should carry sections for 1910 hazards (machine guarding, HazCom, lockout/tagout on maintenance work) and sections for 1926 hazards (fall protection, scaffold safety, excavation on construction work). One program with clearly labeled sections beats two separate binders that nobody keeps in sync.

Training follows the same logic. Workers who do both kinds of work need training on both sets of requirements. The OSHA 30 hour online course for construction covers 1926 content; the general industry version covers 1910 content. If your people cross the line, decide whether supervisors need the construction version, the general industry version, or both.

SafetyFolio's safety program generator asks about your work activities rather than your industry code, because this distinction is the whole ballgame. You can build separate written programs for your general industry and construction operations, or one combined program, depending on how your crews actually work.

Frequently asked questions

My company does landscaping. Are we under 1910 or 1926?

Landscaping falls under 29 CFR 1910 (general industry) for routine tasks like mowing and pruning. But if your crew builds retaining walls, installs hardscape, or runs irrigation lines that involve significant excavation, those activities can trigger 1926 (construction) requirements. OSHA has addressed landscaping in letters of interpretation, and the activity, not the industry label, controls the determination.

Does 29 CFR 1926 apply to homebuilders and residential contractors?

Yes. Residential construction is squarely covered by 1926. OSHA issued a 1995 memorandum and later enforcement guidance making clear that residential builders must meet 1926 fall protection requirements. Compliance directive STD 03-11-002 covers residential construction enforcement. The 6-foot fall protection trigger and the rest of the 1926 requirements apply to houses just like they apply to commercial jobs.

Can OSHA cite a general industry employer under 1926?

Generally no, unless the employer's workers are doing construction work. OSHA can't cite a manufacturing plant under 1926.501 for a fall hazard when the plant's workers are doing general industry tasks. But if that same employer sends its own maintenance crew to build an addition onto the building, those workers doing construction can be cited under 1926 for that specific work.

What is the General Duty Clause and when does it apply instead of 1910 or 1926?

Section 5(a)(1) of the OSH Act requires employers to provide a workplace free from recognized hazards likely to cause death or serious physical harm. OSHA uses it when no specific standard covers the hazard. It applies to general industry and construction employers alike. To cite under it, OSHA has to show the hazard was recognized, a feasible fix existed, and the hazard was likely to cause serious harm.

Are there separate OSHA 10 and OSHA 30 courses for 1910 vs 1926?

Yes. OSHA 10 and OSHA 30 both come in two versions: one for construction (1926 content) and one for general industry (1910 content). They're not interchangeable. A worker who took the construction OSHA 30 has received no training on general industry hazards, and vice versa. Pick the version that matches the standard covering your workers' actual tasks.

Does 29 CFR Part 1904 recordkeeping apply to both general industry and construction?

Yes. 29 CFR Part 1904 (injury and illness recordkeeping) applies to employers in both general industry and construction who have more than 10 employees and aren't in a partially exempt low-hazard industry. The OSHA 300 Log, 300A Summary, and 301 Incident Report requirements are identical no matter which work standard (1910 or 1926) covers your operations.

If I run a demolition company, am I under 1910 or 1926?

Demolition is construction work. 29 CFR 1926 Subpart T covers demolition specifically (1926.850 through 1926.860). Demolition employers must comply with 1926, including fall protection, hazard communication via 1926.59, and the demolition subpart. If your company also maintains equipment in a shop or yard, those non-construction activities fall under 1910.

What standard covers electrical safety: 1910 or 1926?

Both, depending on who's doing the work. 1910 Subpart S covers electrical safety for general industry workers. 1926 Subpart K covers it for construction workers. The two subparts have real differences. The approach boundaries and shock protection requirements for qualified electrical workers, for example, differ between the two. Use the standard that matches the work being performed.

Does the standard change if construction workers come inside an occupied building?

No, not automatically. If workers are inside an occupied building doing construction work (remodeling, adding walls, installing systems), 1926 still applies to their activities. The building being occupied by other workers under 1910 doesn't convert the construction into general industry work. The multi-employer worksite policy may mean the building owner and the contractor both carry responsibilities under their respective standards.

How does OSHA handle hazard communication (HazCom) for construction employers?

Construction employers must comply with 29 CFR 1910.1200, the hazard communication standard. 29 CFR 1926.59 adopts 1910.1200 in full by reference, so the requirements are identical: written HazCom program, safety data sheets for all hazardous chemicals, container labeling, and employee training. HazCom is consistently one of the top cited standards for both general industry and construction employers.

Is lockout/tagout required for construction employers?

1926 has no dedicated lockout/tagout standard equal to 1910.147. OSHA has addressed this through letters of interpretation and enforcement guidance: construction employers must control hazardous energy, and OSHA may cite them under the General Duty Clause or under 1926.417 (electrical lockout) when energy control procedures are missing. In practice, construction employers with servicing and maintenance work should follow 1910.147 as best practice.

What should I do first if I'm not sure which standard covers my company?

List every task your workers perform, not your industry category. Match each task to the definition of construction work in 29 CFR 1926.32(g): building, altering, or repairing a structure. Tasks that meet that definition fall under 1926. Everything else falls under 1910. If you have both, you need written programs and training for both. OSHA's site carries letters of interpretation for specific scenarios.
