Commercial cleaning companies work at client facilities they do not own or control. Their employees perform cleaning tasks in environments where hazards (wet floors, chemical exposures, slip risks, heavy equipment) are created partly by the client's operations and partly by the BSC's own work methods. When OSHA investigates an injury or conducts a programmed inspection at a multi-employer worksite, the agency applies the Multi-Employer Worksite Policy to determine which employers bear liability for observed hazards. Understanding this doctrine is critical for cleaning companies: it determines whether your company is citeable for hazards created by your client, whether your client is citeable for conditions that harm your employees, and what due diligence steps reduce your exposure regardless of who created the hazard.
The Four Employer Roles Under OSHA CPL 02-00-124
1. The Creating Employer: The employer who creates the hazard. If a BSC's cleaning crew creates a wet floor slip hazard in a client building hallway, the BSC is the creating employer. If the client's operations create a chemical spill that BSC employees work near, the client is the creating employer.
A creating employer is citeable for violations affecting any employee on the worksite, not just their own employees. Creating employers have the strongest obligation to abate.
2. The Exposing Employer: The employer whose employees are exposed to the hazard. In commercial cleaning, the BSC is almost always the exposing employer when a hazard affects cleaning crews. An exposing employer is citeable if it knew of the hazard and failed to take protective steps, even if it did not create the hazard.
The exposing employer has an obligation to: (a) inform the creating or controlling employer of the hazard if the exposing employer cannot correct it, and (b) take protective measures for its own employees even while requesting correction from other employers.
3. The Correcting Employer: The employer responsible for correcting the hazard, even if they did not create it. This is typically the employer with the contractual authority and practical ability to fix the hazard (e.g., the building owner's property manager). A correcting employer is citeable if they were asked to correct a hazard and failed to do so within a reasonable time.
4. The Controlling Employer: The employer with general supervisory authority over the worksite, even if it does not directly supervise the employees exposed. OSHA holds controlling employers to a "reasonable care" standard; they must exercise reasonable care in their supervisory role to prevent or discover and correct violations by other employers at the site.
For BSCs: Your client (building owner or property manager) is typically the controlling employer at the facility. You (the BSC) are typically the exposing employer for your crew's hazard exposures. But if you subcontract cleaning services and maintain supervisory authority over the subcontractor's crew, you may be the controlling employer over the subcontractor.
| Scenario | Who Is the Creating Employer? | Who Is the Exposing Employer? | Who Is the Controlling Employer? | OSHA Citation Risk |
|---|---|---|---|---|
| BSC crew creates wet floor without warning signs; employee slips | BSC | BSC | Building owner/PM | BSC cited (creating + exposing); possible citation to building owner if they had supervisory role over cleaning ops |
| Client's renovation crew creates construction dust; BSC cleaners exposed without respirators | General contractor/client | BSC | General contractor | BSC cited as exposing employer for not providing respirators; GC cited as creating employer |
| BSC subcontracts cleaning; subcontractor's employee injured by unlabeled chemical | BSC (provided chemicals) | Subcontractor | BSC (if supervising subcontractor) | BSC cited as creating employer; possible controlling employer citation; subcontractor cited as exposing employer |
| Client's electrical contractor leaves exposed wiring; BSC crew works in area | Electrical contractor | BSC | Building owner/GC | BSC cited as exposing employer for not removing crew from hazardous area; electrical contractor cited as creating employer |
| Client's facility has inadequate lighting in stairwells; BSC crew falls | Building owner | BSC | Building owner | BSC cited if it knew of the hazard and did not address it or notify the building owner; building owner cited as creating and controlling employer |
The Exposing Employer's Duty to Act
When a BSC's employees are exposed to a hazard created by another employer, the exposing employer (the BSC) cannot simply point to the other party and disclaim responsibility. OSHA CPL 02-00-124 requires the exposing employer to take reasonable protective steps:
Step 1: Notify the creating or controlling employer: Formally notify the client (building owner or property manager) of the hazard in writing. A verbal mention to a facilities contact does not create a defensible record; a written email or incident report does.
Step 2: Take interim protective measures: If the hazard cannot be immediately corrected, protect your crew: remove them from the hazardous area, provide appropriate PPE, or implement administrative controls (e.g., restrict the cleaning zone until the hazard is abated).
Step 3: Establish a timeline for correction: Document that you notified the controlling employer and set a reasonable deadline for hazard abatement. If the hazard persists beyond a reasonable time and continues to expose your employees, you may need to escalate: up to and including removal of your crew from the building.
Step 4: Document everything: The OSHA multi-employer doctrine turns heavily on what the employer knew and when. A contemporaneous written record of hazard notification and protective steps creates your legal defense; no documentation creates the assumption you did nothing.
Contract Provisions That Shift Multi-Employer Risk
Sophisticated facility service agreements address multi-employer liability allocation in their contract language. When negotiating service contracts, advocate for these provisions:
Client's duty to maintain premises: A clause requiring the client to maintain the facility in a condition that does not create unreasonable hazards for BSC employees: specifying adequate lighting, safe stair conditions, no exposed utilities, etc.
Hazard notification protocol: A clause requiring the client to notify the BSC of any hazardous conditions created by other contractors, renovation work, or facility operations before BSC crews begin work in affected areas.
Indemnification: A mutual indemnification provision where the client indemnifies the BSC for claims arising from hazards created by the client or other contractors at the facility; and the BSC indemnifies the client for claims arising from BSC operations.
PPE provision: Clarity on who is responsible for providing what PPE. Standard practice is for BSCs to provide chemical and cleaning PPE; clients to address site-specific hazards (e.g., fall protection equipment in unusual high-work situations).
Practical Compliance Program for Multi-Employer Contexts
- Pre-contract site walk: Before beginning service at any new account, conduct a documented safety walk identifying existing hazards. Create a written record of pre-existing conditions you observed and communicated to the client
- Ongoing hazard reporting system: Establish a reporting mechanism for field supervisors to flag hazards in client facilities: a simple digital form with photo upload creates a defensible record
- Subcontractor oversight: If you subcontract any cleaning work, treat yourself as the controlling employer and implement equivalent safety requirements for subcontractor crews
- OSHA 300 log accuracy: Record injuries that occur at client facilities on your 300 log; these are your employees' injuries regardless of where the hazard originated
Frequently Asked Questions
A structural defect in our client's building injured one of our cleaners: can OSHA cite us for a hazard we didn't create?
Potentially yes, in your role as the exposing employer. The question OSHA asks is whether you knew or should have known about the defect and failed to take protective steps: pulling the crew, notifying the building owner, requesting abatement. Primary liability rests with the building owner as the creating and controlling employer, but that placement does not move you off the hook for putting people in front of a hazard you were already aware of.
Our client maintains a full OSHA compliance program for their own staff: does that cover our crew too?
No, and it is one of the more expensive assumptions in contract cleaning. Their internal program protects their employees; your company is responsible for the safety program covering yours. The OSHA employer-employee relationship is non-delegable, so you cannot hand off your employees' compliance obligations to a client along with the scope of work, no matter how complete their binder looks on the shelf.
What is the deadline and the argument if we want to contest a citation for a hazard someone else created?
File a Notice of Contest within 15 working days of receiving the citation; miss that window and it stands regardless of merit. In the written contest and at the OSHRC hearing that follows, your defense needs three legs: that you were not the creating employer, that you notified the controlling employer of the hazard, and that you took reasonable protective measures for your crew. Each leg has to rest on a dated record rather than a recollection.
Which employer role does a cleaning contractor typically occupy on a shared worksite?
Nearly always the exposing employer: the party whose people stand in a hazard that another company created and controls. That role carries less weight than the creating and controlling employer's, but it is no free pass. Your position holds only if you can show you recognized the hazard, told the party who controls the space, and protected your crew while abatement was pending.
