50-person crew, 10-hour days. Weekly or bi-weekly service?
We have a 50-person crew on a six-month commercial job in Phoenix. They work 10-hour days, Monday through Friday. The heat is intense. I ordered three standard portable toilets and one ADA-compliant unit, which meets the OSHA 1926.51 minimum for the crew size. The rental company is on a weekly service visit schedule. By Wednesday, the units are a mess. The holding tank is near full, and the smell is strong even with the deodorizer. The crew is complaining. Should I switch to a bi-weekly service, or is there a better setup for this kind of heavy use? Would a different type of unit hold up better?
