OSHA 1926.51: 125 workers on a November 2026 bridge project

OSHA 1926.51(c) requires one toilet seat and one urinal per 40 workers for a crew of 125. You need four toilet seats and four urinals total. Add one ADA-compliant portable toilet to meet the ADA 5 percent cluster rule.

Standard units work for bridge sites. Use non-flushing standard portable toilets with holding tanks. They handle shifts and rough conditions. Place them on level ground near work zones with truck access for weekly service visits.

Service frequency is weekly in normal use. November weather means less odor, but weekly pumping keeps units clean. Vandalism happens on remote sites. Lockable units help. Staking prevents tip-overs in wind.

High-rise or crane-lift units are not needed here. Ground placement works for bridge abutments and deck crews. If you have crews working on piers over water, discuss barge placement with your rental company.

Order five standard units, four urinals, and one ADA unit. Set a weekly service schedule. Confirm the vacuum truck can reach all spots. Anyone run a similar site? Post your setup or questions.

OSHA 1926.51(c) requires one toilet seat and one urinal per 40 workers for 125 workers, so you need four toilet seats and four urinals total. Add one ADA-compliant portable toilet to meet the ADA cluster rule. Standard units are the right choice for a bridge project. They are durable, handle shifts well, and don't require water or power. Place them on level ground with clear truck access for weekly service visits. Weekly service is standard, even in November, to keep units clean and prevent issues. Lockable units help with vandalism, and staking prevents tip-overs in wind. If crews are working over water on piers, talk to your rental company about barge placement options. Order five standard units (to cover the four toilet seats plus one ADA unit) and four urinals, and confirm the vacuum truck can reach all spots.
