OSHA Compliance Guide for Job Sites

The Golden Rule: One Toilet is Not Enough

OSHA requires a minimum number of toilets based on the size of your workforce. Failing to meet these ratios can lead to immediate site shutdowns and heavy penalties.

  • 1–20 Employees: 1 Toilet minimum.
  • 21–199 Employees: 1 Toilet and 1 Urinal per 40 workers.
  • 200+ Employees: 1 Toilet and 1 Urinal per 50 workers.

Pro Tip: For mobile crews, toilets must be readily available. Our Towable Units ensure your team stays compliant even as the job site moves.

Hygiene is Not Optional: Handwashing Requirements

Sanitizer is a supplement, not a replacement. OSHA mandates that handwashing facilities must be provided on all construction sites to prevent the spread of harmful contaminants and diseases.

  • Fresh Water Access: Stations must provide clean water and soap.
  • Drying Means: Single-use paper towels must be provided (no shared towels).
  • Proximity: Stations must be located in close proximity to the toilet facilities.

Accessibility & Visibility: Placement Protocols

Where you place your units is just as important as how many you have. Proper placement ensures worker safety and operational efficiency.

  • Easy Access: Units must be illuminated and accessible at all times without creating a tripping hazard.
  • Distance: Workers should not have to walk an unreasonable distance to reach a restroom.
  • Ventilation: All units must be properly ventilated and maintained in a sanitary condition to meet health codes.
