Questions
How many porta potties do I need for my event?
Plan on 1 unit per 50 guests for an event of up to 4 hours. Add about an eighth more for every extra hour, and a fifth more if you serve alcohol. Include at least one ADA unit for public events. The calculator does the math.
How many units does OSHA require on a jobsite?
The federal rule (29 CFR 1926.51) asks for at least 1 toilet for up to 20 workers, and 1 toilet plus 1 urinal per 40 workers above that. A standard unit has both. Many crews order 1 unit per 10 workers so units stay usable between weekly cleanings.
