Built around the regulation:

OSHA Worker Ratios for Unit Quantity Planning

OSHA 1926.51(c) mandates one portable toilet per twenty workers for a standard work week. Crew size, shift duration, and water access determine the necessary unit count for your site. Our dispatch adjusts these requirements based on your specific job site needs. Review the crew-size cards below to determine your equipment allocation.

1 per 20 Workers

One toilet per twenty workers is standard for crews of twenty or fewer.

Female-Worker Add

Crews with mixed genders get separate stalls for privacy.

Urinal Substitution

One urinal counts as one fixture up to one third of the total.

Large-Crew Step

Crews of 200 or more workers require one fixture per 40 workers per shift.

Weekly Servicing Schedules on Active Job Sites

Active construction sites in Columbia receive weekly service for crews under twenty, while thirty or more workers necessitate twice-weekly visits to manage waste. Our driver utilizes a vacuum pumper truck to clear the holding tank, performs a pressure rinse, and installs a fresh deodorizer puck. We restock paper supplies and log each visit, providing the documentation needed for site supervisors to maintain compliance with OSHA 1926.51(c) protocols.

Rough-Site Logistics with Crane-Liftable Units

High-rise builds in Columbia need jobsite units that move with the work—our crane-liftable restrooms have a reinforced steel cage and rigging eyes for tower crane hoisting. The skid-mounted base lands on each hoist deck; rugged casters roll units into place. Anchor on gravel or bolt to concrete pads between phases. Waste tank servicing uses a suction hose from the holding tank to our vacuum trucks, complying with the OSHA 1910.141 sanitation rule for construction worker restrooms. Relocate units across Richland as floors complete; see monthly construction portable toilet rental pricing for tiered contracts.

Construction Site Questions

  • + How many units do I need for a thirty-worker crew?

    Two standard units provide sufficient waste tank capacity for thirty workers under OSHA 1926.51(c), while adding an ADA unit ensures compliance on public-funded projects.

  • + Can the service day be locked to a specific weekday?

    Monthly contracts secure a fixed weekday and route window maintained for the entire life of your construction project.

  • + What does monthly billing include?

    Delivery, weekly servicing, paper and sanitizer top-ups, final pickup and phase relocations on long-term contracts.

  • + Do you deliver to active concrete pours?

    Concrete pours need the drop scheduled ahead of the pour, staged clear of the forms on gravel, then reposition once the pad cures.
