Can a standard porta potty handle a wheelchair user temporarily?
I'm organizing a small outdoor fundraiser this weekend, about 75 people expected over four hours. We have food trucks and beer, so I rented three standard portable toilets and one handwash station. They're placed on level grass near the parking area, so the service truck can reach them easily. Yesterday, a volunteer told me her father uses a manual wheelchair and is coming. I don't have an ADA-compliant unit. Is a standard porta potty ever acceptable for a wheelchair user, even temporarily? Or is it completely unusable and unsafe? Should I try to upgrade one unit last minute, or is there another solution?
