Industry-specific OSHA standards that override general industry rules

Last updated 2026-07-10

How does OSHA's standard hierarchy actually work?

OSHA has no single rulebook that treats every workplace alike. It has sector-specific sets of standards, and one principle runs through all of them: the more specific standard wins.

Four parts of Title 29 of the Code of Federal Regulations (CFR) cover most private-sector workplaces:

• 29 CFR 1910, General Industry (manufacturing, warehousing, retail, healthcare, and most service businesses)
• 29 CFR 1926, Construction
• 29 CFR 1915, 1917, 1918, Maritime (shipyard employment, marine terminals, and longshoring)
• 29 CFR 1928, Agriculture

When OSHA has written a standard for a hazard in your sector, that standard is the one that applies. A construction employer who cites a general industry lockout/tagout rule during an audit is citing the wrong book. The construction-specific rules in 1926 Subpart S cover electrical safety, and when they address a topic, they control ^[1].

The gaps are where it gets interesting. If your sector standard says nothing about a particular hazard, OSHA can reach back to general industry standards. If those don't apply either, it cites the General Duty Clause, Section 5(a)(1) of the OSH Act, which requires employers to keep the workplace free from recognized hazards likely to cause death or serious physical harm ^[2]. That's the catch-all, and it's broader than most employers think.

Which industries have their own separate OSHA standards?

Four sectors have dedicated subchapters in 29 CFR because their hazards are different enough to need tailored rules.

Construction (29 CFR 1926). This is the most heavily regulated specific-industry sector. It covers scaffolding (Subpart L), fall protection (Subpart M), excavations (Subpart P), and cranes (Subpart CC). Construction also draws the most enforcement attention. In fiscal year 2023, fall protection in construction (1926.501) was OSHA's single most-cited standard for the 13th straight year ^[3].

Maritime (29 CFR 1915, 1917, 1918). Shipyard employment, marine terminals, and longshoring each get their own part. These aren't minor variations. The confined space rules in shipyard employment (1915.12) look meaningfully different from the general industry permit-required confined spaces standard (1910.146), because the hazards inside a ship's hull are genuinely different from those in a manufacturing tank.

Agriculture (29 CFR 1928). Agriculture has the thinnest specific-industry coverage of any sector. It handles tractor safety (1928.51), field sanitation (1928.110), and a handful of others. Because the coverage is so light, ag employers fall back on general industry or the General Duty Clause far more often than construction employers do.

General Industry (29 CFR 1910). This is the default. If you're not construction, maritime, or agriculture, this is your primary standard. It covers manufacturing, warehousing, healthcare, retail, food processing, and most of the American economy. It's also the fallback for specific-industry employers when their own subchapter is silent.

One category surprises people: federal contractors and federal agencies are covered by 29 CFR 1960, the basic program elements for federal employee occupational safety, which is administered differently from private-sector standards ^[4].

What does it actually mean when a specific standard overrides a general one?

It means your compliance obligations change, sometimes a lot.

Take fall protection. Under general industry (1910.28), workers on walking-working surfaces must be protected from falls of four feet or more. Under construction (1926.501), the trigger is also four feet for most surfaces, but the methods and specific triggers differ by activity. Leading edges, holes, roofing work, and steel erection each get their own provisions. A construction employer can't adopt 1910.28 and call it done. They have to work through 1926.501 and its subpart.

Or take hazard communication. The general industry standard, hazard communication (1910.1200), requires Safety Data Sheets, labels, and employee training. Construction and shipyard employers are covered by 1910.1200 too, applied through their sector's rules. Agriculture adds a pesticide-specific labeling requirement under 1928.1027 that runs alongside 1910.1200 rather than replacing it.

Here's the practical rule. Don't search "OSHA rule" generically. Search your CFR subchapter first. If a rule directly addresses your hazard, that's the one OSHA will cite you under. If nothing does, then you work backward toward general industry and the General Duty Clause.

OSHA has confirmed this hierarchy in its letters of interpretation and its Field Operations Manual, which states that the General Duty Clause is used only where no specific standard applies to the hazard ^[2]. That policy is the clearest statement of the rule you'll find outside the CFR itself.

How do construction-specific standards differ from general industry?

Construction has the most fully built-out sector standard set, so the differences are many and they matter operationally.

Hazard	General Industry (1910)	Construction (1926)
Fall protection threshold	4 ft (1910.28)	4 ft most surfaces, specific rules by task (1926.501)
Scaffolding	1910.28 walking-working surfaces	Dedicated Subpart L (1926.450-452)
Excavation/trenching	Not addressed specifically	Dedicated Subpart P (1926.650-652)
Cranes and derricks	1910.179-180	Dedicated Subpart CC (1926.1400-1442)
Electrical safety	1910.301-399	1926.400-449 (different training/approach requirements)
Lockout/tagout	1910.147 (very specific)	1926.417 (briefer; 1910.147 often cited as the practical standard)

The crane rules in construction (1926 Subpart CC) show how specific the differences get. They require operators to be certified, either through an accredited certifying organization or an employer-audited program ^[5]. That certification requirement doesn't exist the same way in 1910's general overhead crane rules.

Workers who do both construction and general industry work create real headaches. A company that runs in-plant maintenance and renovation construction may have the same crew covered by different standards depending on what they touch that day. OSHA's position is plain: the nature of the work determines the applicable standard, not the employer's primary industry classification.

What are the maritime-specific standards and how are they different?

Maritime is the sector most outside employers know least about, which is a problem, because the penalties for getting it wrong are identical.

29 CFR 1915 covers shipyard employment. 29 CFR 1917 covers marine terminals. 29 CFR 1918 covers longshoring. They aren't interchangeable. A marine terminal employer can't just apply 1915 rules because the site sits near water.

The confined space rules in 1915 Subpart B show how far the standards drift apart. In general industry, 1910.146 defines permit-required confined spaces and mandates a permit system, attendants, and rescue procedures. In shipyard employment, 1915.12 covers the same hazard but adds requirements built around ship structures. Inerting with CO2 or nitrogen is common in ship holds, the geometry of the spaces is different, and the rescue access problems are unique. The training and atmospheric testing rules overlap heavily but aren't identical ^[6].

A blanket general industry safety program misses all of this. If OSHA walks into a shipyard and finds the general industry confined space program running unchanged, that's a likely citation under 1915.12, not 1910.146.

How does agriculture's standard coverage differ from other sectors?

Agriculture has the sparsest specific-industry coverage of the four sectors. 29 CFR 1928 currently addresses:

• Agricultural equipment (1928.51-57, mostly tractor rollover protection)
• Field sanitation for hand-labor operations (1928.110)
• Temporary labor camps
• Hazardous chemicals in agriculture (1928.1027)
• A limited set of general environmental controls

That's a short list for an industry with one of the highest fatality rates in the country. The Bureau of Labor Statistics reported a fatal injury rate of 20.4 per 100,000 full-time equivalent workers in agriculture, forestry, fishing, and hunting in 2022, against 3.7 per 100,000 for all private industry ^[7]. Roughly five and a half times the average.

Because 1928 covers so little, OSHA leans hard on the General Duty Clause for ag hazards that have no specific standard. Grain handling is one exception. 1910.272, a general industry standard, specifically covers grain elevators, feed mills, and flour mills even when they sit on farms or in agricultural settings. Its scope language pulls those facilities into general industry coverage regardless of the broader business category ^[11].

Small farms carry a complicated exemption. Since the 1970s, Congress has attached appropriations riders that limit OSHA enforcement on farms with 10 or fewer employees that don't run a temporary labor camp. This isn't in the CFR. It's annually renewed legislation. The exemption doesn't erase legal obligations. It means OSHA doesn't enforce against those farms. The General Duty Clause technically still applies ^[8].

What happens when no specific standard covers a hazard?

This is where the General Duty Clause does most of its work.

Section 5(a)(1) of the OSH Act reads: "Each employer shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees" ^[2]. That's the full text of the clause. Short and broad.

For a General Duty Clause citation to hold, OSHA has to prove four things: the employer failed to keep the workplace free of a hazard; the hazard was recognized (by the employer, the industry, or common sense); the hazard was causing or likely to cause death or serious harm; and a feasible means existed to reduce or eliminate it.

Common 5(a)(1) citation areas are heat illness (no specific general industry heat standard exists yet, though OSHA has published guidance and proposed a rule), workplace violence in healthcare and social services, and ergonomic hazards. OSHA has cited employers for all three under 5(a)(1) when no specific standard applied.

Having a stack of specific standards doesn't buy you immunity. If a construction employer has a recognized hazard that 1926 simply doesn't address, OSHA can still cite under 5(a)(1).

Do state OSHA plans have their own industry-specific standards?

Yes, and it's an underrated source of compliance complexity.

OSHA authorizes state plans under Section 18 of the OSH Act. As of 2024, 22 states and two territories run state plans that cover private-sector employers ^[9]. These states must adopt standards at least as effective as the federal ones, and they can go further.

California's Cal/OSHA is the clearest example. It has sector-specific standards for tunnel construction, logging, petroleum refining, and heat illness, including an outdoor heat illness standard at 8 CCR 3395 that predates federal OSHA's proposed rule by nearly two decades. California's Indoor Heat Illness Prevention standard took effect in 2024 and covers indoor workplaces at or above 82 degrees Fahrenheit. Nothing comparable exists federally.

Washington (L&I) and Oregon (OR-OSHA) also have sector rules that run past their federal counterparts in logging, agriculture, and forest activities.

The practical rule in a state plan state: check your state standard first, then federal. Where the state standard is stricter, it controls. The full list of state plan states and links to their rules is at OSHA.gov ^[9].

How do you figure out which standard applies to your specific workplace?

Start with the nature of the work, not the SIC code.

OSHA's coverage follows the work activity, not how the IRS or the Census Bureau classifies the business. A facilities company that does cleaning (general industry) and renovation (construction) may have the same employees covered by both 1910 and 1926, depending on the task and the day.

The decision tree is short:

1. Is the work construction? (Definition: construction, alteration, or repair, including painting and decorating, 29 CFR 1926.32(g).) If yes, 1926 applies. 2. Is the work shipyard, marine terminal, or longshoring? If yes, 1915, 1917, or 1918 applies. 3. Is the work agricultural operations? If yes, 1928 applies. 4. None of the above? General industry (1910) is your primary standard.

Once you know your primary standard, search that subchapter for the specific hazard. If it's addressed there, use that rule. If not, check 1910. If 1910 is silent too, the General Duty Clause is your applicable standard.

For written programs, this matters more than most owners realize. Your lockout/tagout program has to be built on the right standard, your fall protection plan has to cite the correct subpart, and your incident report and recordkeeping processes should reference the right CFR part. If you're building from scratch, SafetyFolio's safety program generator takes your industry as input and pulls the correct sector-specific standards, which cuts out the cross-referencing that trips people up.

OSHA's site has a standards search that filters by industry, and its compliance assistance pages include sector guides for construction, maritime, and agriculture that put the CFR into plain language ^[1].

What are the most commonly cited sector-specific standards?

OSHA publishes its top-10 most cited standards every year, and the split by sector tells the whole story.

Construction, fiscal year 2023 ^[3]:

Rank	Standard	Topic
1	1926.501	Fall protection (duty to have)
2	1926.1053	Ladders
3	1926.503	Fall protection training
4	1926.451	Scaffolding (general requirements)
5	1926.102	Eye and face protection

General industry, fiscal year 2023:

Rank	Standard	Topic
1	1910.1200	Hazard communication
2	1910.147	Lockout/tagout
3	1910.132	PPE (general requirements)
4	1910.178	Powered industrial trucks (forklifts)
5	1910.303	Electrical (general requirements)

The separation is stark. The number one construction citation, fall protection, doesn't crack the general industry top 10, and none of the top general industry standards show up in construction's list. That's what sector-specific standards look like when they work. The hazards that matter most to each industry generate the most enforcement.

For forklift certification, 1910.178 is the general industry standard and the right citation for warehouse and manufacturing employers. A construction employer running forklifts on a jobsite gets cited under 1926.602 instead.

For OSHA training, knowing which standard controls isn't academic. Training content, frequency, and documentation can all differ between sectors. Getting them right is what keeps your program defensible during an inspection.

Should your written safety program reference the specific CFR citation?

Yes, and it matters more than most templated programs admit.

A program that says "we comply with OSHA standards" without citing the actual regulation is legally weaker and practically useless. During an inspection, the compliance officer checks your program against the specific standard. If your program cites 1910.147 for lockout/tagout and you're a construction employer, the officer notes that you're running the wrong program. That's not an automatic citation, but it signals a compliance culture problem that invites a closer look at everything else.

The bigger reason is your own people. A fall protection plan that says "comply with applicable OSHA fall protection rules" tells a supervisor nothing. "Comply with 29 CFR 1926.502 (fall protection systems criteria)" tells them exactly what to read.

The specific citation is the anchor. Build the program from the regulation, not from generic templates that don't know your sector. SafetyFolio's program generator does this by design. You specify your industry, and the output cites the right CFR sections.

If you're taking an OSHA 30 course, sector-specific standards are covered explicitly. The construction OSHA 30 covers 1926. The general industry version covers 1910. They aren't interchangeable, and using the wrong one means your supervisors are trained on rules that don't govern their work.

What are the penalties for being cited under the wrong standard or missing a sector-specific rule?

The penalty is the same whether OSHA cites a specific standard or the General Duty Clause. What drives the dollar figure is the classification of the violation.

As of January 2024, OSHA penalties (adjusted annually for inflation under the Federal Civil Penalties Inflation Adjustment Act) are ^[10]:

• Other-than-serious violations: up to $16,131 per violation
• Serious violations: up to $16,131 per violation
• Willful or repeated violations: up to $161,323 per violation

Classification matters more than which standard was violated. A willful violation of a construction-specific rule (say, knowingly ignoring 1926.501 fall protection) carries the same maximum as a willful general industry violation.

Sector does matter for the repeat-violation calculation. A repeat requires a prior citation for the "same or substantially similar" standard. If OSHA cited you under a general industry standard and later finds you violating the analogous construction standard, whether that counts as a repeat depends on how closely related OSHA considers them. That question has been litigated before the Occupational Safety and Health Review Commission.

For small businesses, the penalties bite, and OSHA does offer reductions. Employers with 25 or fewer workers can get up to a 60% penalty reduction; those with 26 to 100 workers can get up to 40% ^[10]. Those reductions don't protect you from citations that come from running the wrong standard for your sector.

Frequently asked questions

If I do both construction and general industry work, which OSHA standard applies?

It depends on the specific task, not the employer's industry classification. When workers are doing construction work (building, alteration, or repair), 29 CFR 1926 applies to those activities. When the same workers do maintenance or manufacturing work, 29 CFR 1910 applies. OSHA has confirmed in multiple letters of interpretation that the nature of the work activity controls, not the company's primary business description.

Can OSHA cite me under the General Duty Clause if there's already a specific standard for my industry?

Generally, no. OSHA's own policy is that when a specific standard addresses a hazard, the General Duty Clause is not used in its place. If the specific standard doesn't fully address the hazard, or the employer violates the spirit of a rule in a way the language doesn't capture, OSHA has cited both together. The Review Commission has sometimes vacated those dual citations.

Are there OSHA standards specific to healthcare?

Healthcare falls under general industry (29 CFR 1910), but several 1910 standards are written mainly with healthcare in mind. The bloodborne pathogens standard (1910.1030), the formaldehyde standard (1910.1048), and the ionizing radiation standard (1910.1096) are examples. OSHA proposed a healthcare COVID-19 standard (later withdrawn) and has advanced a healthcare workplace violence rule. Until a healthcare subpart is finalized, the relevant 1910 standards and the General Duty Clause are what apply.

Does the construction standard (1926) apply to maintenance workers doing repairs inside a factory?

Not automatically. Maintenance inside an existing structure is usually general industry work unless it involves alteration, repair of the structure itself, or new construction. Routine equipment maintenance is covered by 1910. Renovating or structurally repairing the building triggers 1926. The line isn't always clean, and OSHA has addressed specific scenarios in letters of interpretation, which are searchable at osha.gov.

What is the General Duty Clause and when does it apply?

Section 5(a)(1) of the OSH Act requires every employer to provide a workplace free from recognized hazards likely to cause death or serious physical harm. OSHA uses it when no specific standard addresses a hazard. Common citation areas include heat illness in general industry, workplace violence in healthcare, and ergonomic hazards. To cite under it, OSHA must show the hazard was recognized and that a feasible abatement method exists.

Do state OSHA plans have to follow the same industry-specific structure as federal OSHA?

State plans must adopt standards at least as effective as the federal ones, but they can go further. California, for example, has heat illness standards for both outdoor and indoor workers that go beyond anything in federal 29 CFR. Washington and Oregon have logging-specific standards stricter than the federal equivalents. In one of the 22 state plan states, your state's sector rules may impose additional or different requirements than the federal CFR.

Is the lockout/tagout standard different for construction workers?

Yes. General industry lockout/tagout (1910.147) is detailed and requires a specific written program, machine-specific procedures, and annual inspections. The construction electrical safety standard (1926.417) covers similar ground but more briefly, and is less prescriptive. Many construction employers model their lockout programs on 1910.147 because it's more fleshed out, and OSHA has accepted this. But 1926 is still the controlling standard, and gaps in 1926.417 don't automatically import 1910.147's full requirements.

How often does OSHA update sector-specific standards?

Rarely and slowly. Major OSHA rulemaking usually takes 5 to 10 years from proposed rule to final rule because of the notice-and-comment requirements of the Administrative Procedure Act. The construction crane standard in 1926 Subpart CC was years in development before its 2010 publication. The walking-working surfaces update for general industry (1910 Subpart D) took decades. Emergency temporary standards move faster but are legally vulnerable to challenge.

What OSHA standard covers grain handling facilities, even if they're on a farm?

29 CFR 1910.272, the grain handling facilities standard, is a general industry standard that explicitly covers grain elevators, feed mills, flour mills, and similar facilities regardless of whether they sit on an agricultural operation. This is one of the clearest cases of a general industry standard pulling a facility out of the agricultural 1928 framework and into 1910, based on the nature of the operation rather than the broader business category.

Does OSHA's forklift standard apply to construction sites?

The general industry forklift (powered industrial truck) standard is 1910.178. Construction sites with forklifts or rough-terrain forklifts are covered by 1926.602 instead. The training and inspection requirements overlap, but they aren't identical. A warehouse employer should build their forklift program around 1910.178; a construction employer should use 1926.602. Using the wrong citation in a written program creates compliance gaps that show up during an inspection.

How do I find the OSHA standard that applies to my specific hazard?

Start at osha.gov and use the standards search, filtering by your sector (construction, maritime, agriculture, or general industry). Search your hazard by keyword in that sector's subchapter. If nothing addresses it, check 1910 as a secondary reference. If 1910 is silent too, the General Duty Clause is your applicable standard. OSHA's compliance assistance pages for each sector also provide plain-language summaries of the most commonly applicable rules.

Are small farms exempt from OSHA standards?

Farms with 10 or fewer employees that don't operate a temporary labor camp have historically been exempt from OSHA enforcement under annual Congressional appropriations riders. This exemption is not in the CFR itself but has been renewed consistently since the 1970s. It limits enforcement, not legal obligation. Farms above 10 employees, and all operations running temporary labor camps, are subject to both 29 CFR 1928 and enforcement by OSHA or a state plan agency.

What OSHA training is required if my company works under multiple industry standards?

Workers must be trained to the standard that covers their actual tasks. Someone who does warehouse work (1910) and construction renovation (1926) needs training that addresses both. OSHA 30 courses are sector-specific: the construction version covers 1926, the general industry version covers 1910. If your workers move between sectors regularly, consider whether both courses fit, or whether task-specific training documented to the right CFR section covers the gap.
