Exposing Employer
Under OSHA's Multi-Employer Citation Policy (CPL 02-00-124), the exposing employer is an employer whose own employees are exposed to a hazard — regardless of who created it. If the exposing employer created the hazard, it is citable. If another employer created it, the exposing employer is still citable when it knew (or should have known) of the hazard and failed to take reasonable protective steps: correcting it if within its authority, or otherwise asking the creating/controlling employer to correct it, informing its employees, and taking feasible alternative protective measures.
Also known as: exposing subcontractor
Exposing Employer at a glance
- Defined in OSHA's Multi-Employer Citation Policy, CPL 02-00-124.
- Citable when its own employees are exposed to a hazard — whether or not it created the hazard.
- If it lacks authority to correct a hazard created by another employer, it must: (1) ask the creating/controlling employer to correct it; (2) inform its own employees of the hazard; and (3) take reasonable alternative protective measures.
- In extreme cases, the exposing employer may have to remove its employees from the job to avoid the hazard.
- Knowledge element: citable if it knew of the hazard OR failed to exercise reasonable diligence to discover it.
- The same employer can be both the exposing and the creating employer if it created a hazard its own workers face.
In plain English
The employer whose own workers are in harm's way. Even if a different company created the danger, this employer can't just let its people work in it. It has to protect them — fix the hazard if it can, and if it can't, push the responsible party to fix it, warn its workers, and put temporary safeguards in place.
What the source says, in summary
The exposing employer is an employer whose own employees are exposed to the hazard... If the exposing employer created the violation, it is citable for the violation as a creating employer. If the violation was created by another employer, the exposing employer is citable if it (1) knew of the hazardous condition or failed to exercise reasonable diligence to discover the condition, and (2) failed to take steps consistent with its authority to protect its employees.
In context
A concept governed primarily by OSHA's construction standards, 29 CFR Part 1926 — the rules that apply on jobsites rather than the general-industry 1910 set.
Example
A drywall subcontractor's crew works on a floor where the general contractor left an unguarded skylight opening (a hazard the GC's actions created). The drywall sub is the EXPOSING employer: its own workers are exposed. Even though it did not create the opening, it cannot let its crew work near it unprotected. Its obligations: ask the GC to guard the opening, warn its own workers of the fall hazard, and put up its own temporary cover or barrier as an interim measure. If it does none of these, OSHA can cite the drywall sub as an exposing employer — in addition to citing the GC.
Why it matters
The exposing-employer rule means a subcontractor cannot escape liability by pointing at whoever created a hazard. If your employees are exposed, you have an independent duty to protect them. This drives the practice of subcontractors documenting hazard notifications to the GC, warning their own crews, and deploying interim safeguards — because 'someone else created it' is not a defense when your own workers are the ones at risk.
Exposing employer vs. controlling employer
These two roles are often confused because both can be cited for the same hazard. The EXPOSING employer's OWN employees are exposed to the hazard — its duty flows from protecting its workforce. The CONTROLLING employer has general supervisory authority over the whole site (usually the GC) — its duty flows from site-wide oversight, and it can be cited even when none of its own workers are exposed. A subcontractor is usually an exposing employer; the general contractor is usually the controlling employer. One incident can produce citations to both.
Exposing Employer — Obligations When Another Employer Created the Hazard
| Step | Obligation |
|---|---|
| 1. Correct if able | Correct the hazard if within its own authority |
| 2. Notify | Ask the creating/controlling employer to correct it |
| 3. Inform | Inform its own exposed employees of the hazard |
| 4. Protect | Take reasonable alternative protective measures |
| 5. Remove (extreme) | Remove employees from the job where no other option protects them |
Exposing Employer: frequently asked questions
- Can an exposing employer be cited for a hazard it did not create?
- Yes. Under the Multi-Employer Citation Policy, an exposing employer is citable for a hazard created by another employer if it knew of the hazard (or failed to exercise reasonable diligence to discover it) AND failed to take steps consistent with its authority to protect its employees. Being a passive bystander to a hazard your own workers face is not a defense — you must act to protect them.
- What must an exposing employer do if it can't fix the hazard itself?
- If the exposing employer lacks the authority to correct the hazard, it must (1) ask the creating or controlling employer to correct it, (2) inform its own employees of the hazard, and (3) take reasonable alternative protective measures. In extreme circumstances, where no other measure adequately protects its workers, the exposing employer may need to remove its employees from the affected area.
- Can one company be both the exposing and the creating employer?
- Yes. If an employer creates a hazard to which its own employees are exposed, it occupies both roles — it is the creating employer (because it caused the condition) and the exposing employer (because its workers are exposed). The Multi-Employer Citation Policy roles are not mutually exclusive; a single employer can fall into more than one category for the same hazard.

More Construction terms
The part of Title 29 of the Code of Federal Regulations that contains OSHA's General Industry standards — the default rulebook for most American workplaces (manufacturing, warehousing, healthcare, etc.) that aren't covered by the construction, maritime, or agriculture standards. It includes core rules like Hazard Communication (1910.1200) and the permissible exposure limits (1910.1000). Several 1910 standards are cross-referenced into construction via Part 1926.
29 CFR 1926The part of Title 29 of the Code of Federal Regulations that contains OSHA's Construction standards — the “Safety and Health Regulations for Construction.” It governs construction, alteration, and repair work, with construction-specific rules for fall protection (Subpart M), scaffolds (Subpart L), excavations (Subpart P), electrical (Subpart K), and more. Where a task isn't addressed in 1926, some general-industry (1910) standards apply by reference.
Anchor PointThe secure attachment point a personal fall arrest system (PFAS) ties off to — the “A” in the ABC of fall arrest. Under 29 CFR 1926.502(d)(15), a non-engineered anchorage must support at least 5,000 pounds per attached worker; alternatively, it can be an engineered anchorage designed and supervised by a qualified person with a safety factor of at least two.
Atmospheric TestingMeasuring the air in a confined space (or other hazardous atmosphere) with a calibrated direct-reading instrument before and during entry. OSHA requires testing in a set order — oxygen first, then flammable gases and vapors, then potential toxic contaminants — and defines the acceptable ranges: oxygen 19.5%–23.5%, flammables below 10% of the LEL, toxics below their exposure limits.
BenchingAn excavation cave-in protective system that cuts the sides into a series of horizontal steps (benches), usually with vertical or near-vertical faces between levels. It's one of OSHA's accepted protective systems under Subpart P — but it is NOT permitted in Type C (the least stable) soil.
Competent Person (Excavation)The competent person OSHA's excavation standard (Subpart P) requires on every trenching job — someone trained in soil classification and protective systems, who can identify cave-in and other hazards AND has authority to remove workers and correct problems. They must inspect the excavation daily before work starts, throughout the shift, and after any rain or event that could increase the hazard.
Confined SpaceA space that is large enough for a worker to bodily enter, has limited or restricted means of entry or exit, and is not designed for continuous occupancy. If it also contains — or could contain — a serious hazard (a hazardous atmosphere, engulfment material, an entrapping configuration, or any other recognized serious hazard), it becomes a permit-required confined space (PRCS).
Controlling EmployerUnder OSHA's Multi-Employer Citation Policy (CPL 02-00-124), the controlling employer is an employer with general supervisory authority over a worksite — including the power to correct safety and health violations itself or to require others to correct them. This is typically the general contractor or construction manager. A controlling employer can be cited for a hazard at the site even if none of its own employees are exposed, because it has a duty to exercise reasonable care to prevent and detect violations by the other employers on site.
