OSHA Requirements for Cleaning Companies

Cleaning companies face a unique OSHA challenge: your employees work with hazardous chemicals at client locations you don't control. Bleach, ammonia, industrial degreasers, and disinfectants are the tools of the trade — and mixing the wrong products can produce deadly gases in minutes. In 2019, a restaurant manager in Massachusetts died after mixing an acid-based cleaner with bleach in a walk-in area — the chlorine gas was fatal within minutes.

OSHA holds the cleaning company employer responsible for employee safety, even when workers are on a client's property. Here's what your compliance program needs.

Core OSHA Requirements for Cleaning Businesses

OSHA cleaning company requirements center on the Hazard Communication Standard, but the multi-site nature of cleaning work adds complexity. You must maintain SDS sheets for every product your teams carry, train employees on chemical hazards and safe mixing procedures, provide appropriate PPE, and ensure workers know how to handle chemicals they may encounter at client sites — not just the products they bring.

Cleaning Company Compliance Checklist

1. Inventory all chemicals your company uses — Disinfectants, degreasers, glass cleaners, floor strippers, carpet cleaning agents, restroom cleaners, and any specialty products
2. Collect SDS for every product — Download from manufacturers; products from Diversey, Ecolab, Betco, and Spartan all have downloadable SDS documents (where to find SDS)
3. Make SDS accessible at every job site — Paper binders in each vehicle or a digital system accessible on workers' phones (SDS binder requirements)
4. Label every spray bottle and container — Secondary container labeling is the #1 citation for cleaning companies — and honestly, it is the easiest one to fix. A permanent marker and two minutes per bottle
5. Train on chemical mixing dangers — Never mix bleach with ammonia, acids with bases, or different brand products without checking compatibility (compatibility chart)
6. Provide PPE and enforce usage — Chemical-resistant gloves and eye protection at minimum; PPE selection guide
7. Train on client-site hazards — The Right to Know law gives your workers the right to access SDS for chemicals at client locations
8. Document everything — Keep training records, SDS update logs, and incident reports

The Mixing Problem

The most dangerous scenario in cleaning work is accidental chemical mixing. Bleach (sodium hypochlorite) combined with ammonia-based cleaners produces chloramine gas — toxic enough to hospitalize workers in minutes. Bleach mixed with acidic cleaners produces chlorine gas. These accidents happen when workers switch between products without rinsing surfaces, or when unlabeled spray bottles all look the same. One wrong grab. That is all it takes.

Proper chemical safety training and clear container labeling prevent these incidents. For the full picture on compliance across different industries, see OSHA compliance by industry.

Frequently Asked Questions

Is the cleaning company or the client responsible for OSHA compliance?

Both. The cleaning company is responsible for its employees' safety — including training, PPE, and SDS for the products they use. The client (host employer) is responsible for informing the cleaning company about hazards at their site. OSHA calls this "multi-employer workplace" doctrine.

Do cleaning companies need SDS for client-provided chemicals?

If your employees use chemicals provided by the client, you must ensure they have access to SDS sheets and training for those products. The client is required to make SDS available, but you as the employer must verify your workers can access and understand them.

How do mobile cleaning crews access SDS sheets at different locations?

Digital SDS systems solve the multi-location problem. Instead of stocking paper binders in every vehicle, a cloud-based SDS manager lets workers search for any product from their phone. This meets OSHA's requirement that SDS be "readily accessible during each work shift."
