OSHA requires employers to provide all workers with sanitary and immediately-available toilet facilities (restrooms). The sanitation standards (29 CFR 1910.141, 29 CFR 1926.51 and 29 CFR 1928.110) are intended to ensure that workers do not suffer adverse health effects that can result if toilets are not sanitary and/or are not available when needed.

How do employers ensure restrooms are accessible?

Employers must provide at least the minimum number of toilet facilities, in toilet rooms separate for each sex (see table J-1 in 29 CFR 1910.141), and prompt access to the facilities when needed.  Restroom access frequency needs may vary significantly from worker to worker, and may be affected by medications, fluid intake, air temperature and other factors.

In response to questions about reasonable access to toilet facilities over the last nearly 20 years, OSHA published letters of interpretation that, together, describe how employers ensure prompt access to toilet facilities (see references for letters of interpretation). Employers must:

• Provide an adequate number of restrooms for the size of the workforce to prevent long lines
• Do not impose unreasonable restrictions on restroom use
• Ensure restrictions, such as locking doors or requiring workers to sign out a key, do not cause extended delays
• Allow workers to leave their work locations to use a restroom when needed

Employers may need to be flexible in developing procedures to ensure that workers have access to toilet facilities as needed. Employers with mobile workers must provide readily available transportation that provides prompt access (i.e., less than 10 mins) to restrooms if they are not available at the work location. Toilets for farmworkers must be located no more than a quarter mile from the location where workers are working on similar findings. Also, when work stations require constant coverage (e.g., production lines and bus drivers), employers may implement a system for workers to request relief as long as there are sufficient relief-workers to assure the wait is not unreasonably long.

Restroom Condition

Employers must maintain restrooms in a sanitary condition. Restrooms must provide hot and cold running water or lukewarm water, hand soap or similar cleansing agent and warm air blowers or individual hand towels (e.g., paper or cloth). Waterless hand cleaner and towels/rags are not adequate substitutes for soap and water.
