OSHA 1926.51: Do temp workers count toward the toilet ratio?

Yes, OSHA 1926.51 counts all workers on a construction site toward the toilet ratio, including temporary workers. The standard applies to all employees, and the headcount for your site is 40.

The OSHA 1926.51 rule for construction is specific. For 20 to 199 workers, the minimum is one toilet seat and one urinal per 40 workers. Your site has 40 people, so you need at least one toilet and one urinal. The rule does not differentiate between permanent and temporary labor.

The practical application on a site like yours means ordering the correct number of units. For a crew of 40, you meet the minimum with one standard unit and one portable urinal. Many companies provide a standard unit that includes a urinal, which also satisfies the requirement. You must also follow the ADA cluster rule if you place multiple units together. For your 40-person crew, providing one ADA-compliant unit would exceed the requirement and ensure accessibility.

Managing the units for a long-term rental involves weekly service visits for pumping and cleaning. In Phoenix heat, a unit for 40 people will need that service frequency or more. Place the units on level ground with clear truck access for the vacuum truck.

That's the compliance breakdown for temp workers. Ask if you have a specific scenario.
