How many portable toilets does an industrial site need?
OSHA general industry rule 29 CFR 1910.141 sets minimum toilets by headcount: 1 for up to 15 employees, 2 for 16–35, and 3 for 36–55. Construction work follows 1926.51 instead. In practice, 1 standard unit serviced weekly handles about 10 workers on a 40-hour week.
| Employees | Minimum toilets (Table J-1) |
|---|---|
| 1–15 | 1 |
| 16–35 | 2 |
| 36–55 | 3 |
| 56–80 | 4 |
| 81–110 | 5 |
| 111–150 | 6 |
| Over 150 | 1 more per 40 employees |
Read OSHA 29 CFR 1910.141 sanitation for general industry and OSHA 29 CFR 1926.51 for construction. Your safety manager decides which rule applies. See our OSHA porta potty requirements guide.
How often should industrial porta potties be serviced on a multi-shift site?
A standard porta potty used by 1 shift of 10 workers needs 1 service visit per week. A second or third shift doubles or triples the use, so add units or service visits. From June through September, crews over 10 should get twice-weekly service in Edinburg heat.
| Crew on site | Shifts per day | Typical setup | Service |
|---|---|---|---|
| 10 workers | 1 | 1 standard unit | Weekly (twice weekly June–Sept) |
| 20 workers | 1 | 2 standard units + 1 handwashing station | Weekly (twice weekly June–Sept) |
| 15 workers per shift | 2 | 3 standard units | Twice weekly |
| 20 workers per shift | 3 | 4–6 standard units | 2–3 visits per week |
| Turnaround surge, 60+ contractors | 2–3 | Clusters by gate and work area | 2–3 visits per week |
Each visit: pump the 60-gallon tank, clean and sanitize, deodorize, and restock paper and sanitizer. Extra visits can be added on any business day.

Yes, Brian Rental Works sets up portable toilets for plant shutdowns and turnarounds. Contractor crews can triple a site's headcount for 1 to 6 weeks. We deliver clusters by gate and work area, add handwashing stations, and schedule 2–3 service visits per week during the surge.
