Construction & Job Sites
OSHA 29 CFR 1926.51 sets the minimum number of toilets on a construction site by crew size, and a rental company services the units on a schedule you agree in the contract. This category covers the OSHA table, weekly versus twice-weekly service, high-rise and crane-liftable units, hand washing, winter operation, vandalism and what a monthly site rental includes.
