OSHA 1926.51: 130 workers, how many toilets and urinals?

OSHA 1926.51 requires 4 toilets and 4 urinals for 130 workers on a construction site. The standard specifies that for 20 to 199 workers, you must provide one toilet seat and one urinal per 40 workers. With 130 workers, dividing by 40 gives 3.25, which rounds up to 4 of each. This ensures compliance and avoids fines.

Crew Details
- Number of workers: 130
- Duration: Long-term (e.g., weeks or months, typical for construction)
- No alcohol or food service on site
- Ground: Level, stable surface like soil or gravel
- Truck access: Required for weekly service visits, with units placed within 25 feet of where the vacuum truck can park

Unit Recommendations
- Use standard portable toilets for cost-efficiency and durability; they are non-flushing with a holding tank and suit construction environments.
- Include at least one ADA-compliant portable toilet per the ADA cluster rule, as OSHA does not override ADA requirements for accessibility.
- Avoid restroom trailers or deluxe units unless needed for client or supervisor facilities, as they add cost and complexity without benefit for crew use.

Service and Compliance
- Schedule weekly service visits for pumping, deodorizer recharge, and cleaning to maintain hygiene and odor control.
- Ensure the rental invoice clearly itemizes units, service frequency, and any ADA compliance to document OSHA adherence.

If your site has mobile crews with access to off-site facilities, you might adjust, but for fixed crews, stick to this count. Questions?
