OSHA Rules for Construction Portable Toilets

On construction sites, whether new builds or renovations, construction companies are obligated under OSHA law to provide access to toilet and sanitation facilities. Construction portable toilets are the way you meet this need, but do you know the rules around how many to rent? If you’re in charge of a construction site, you know you need to ensure your site follows all OSHA rules and regulations. So here’s a closer look at what you need to provide.

How many construction porta potties do you need?

OSHA law dictates employers must provide “adequate and readily accessible sanitation facilities.” But what does that mean, exactly? When it comes to construction porta potties, the number of toilets is based on how many employees are at the worksite at any given time. The OSHA breakdown for toilets is the following:

  • One toilet per gender for one to 15 employees
  • Two toilets per gender for 16 to 35 employees
  • Three toilets per gender for 36 to 55 employees
  • Four toilets per gender for 56 to 80 employees
  • Five toilets per gender for 81 to 110 employees
  • An additional toilet per gender for each additional 40 employees
  • After 200 employees, the number drops to one per 50

A single-occupancy toilet with a locking door counts for both genders, and in addition, temporary worksites may not have to follow these rules if there’s a plumbed toilet nearby or easy transportation to a nearby toilet facility.

There are also voluntary consensus standards in the construction industry. These recommend providing one toilet for every 10 employees during a 40-hour workweek. But if you have crew members on different shifts, or working more than 40 hours a week, it’s a good idea to have extra toilets on site.

Types of construction portable toilets

Believe it or not, there’s more than one type of porta potty. For example, some only have urinals. If you have a primarily male crew, you can order urinal porta potties as long as no more than two-thirds of the facilities are urinal-only. There are also portable toilet trailers with more than one toilet stall inside.

Another option is ordering an ADA-compliant porta potty to accommodate workers with physical disabilities. There are no specific requirements for ADA-accessible toilets, but these should be provided if employees need them. And what if you have sewer toilets on site? If you’re working on a renovation where plumbed facilities are operational, you may not need portable toilets at all. Check local ordinances.

Requirements for hand washing

Hand washing facilities in or near toilets are required, so be sure to ask what’s included in your rental. If hot and cold water aren’t available, then a hand sanitizing gel is required to be mounted in or near the portable toilets. And if the porta potty includes soap and water, then it must also include single-use hand towels or a hand-drying air blower. If your crew members will be exposed to chemicals on the job, you’ll also need a hand washing station in a convenient location.

On a related note, what about eye washing stations? There aren’t a lot of instances where you’ll need a dedicated eye washing station, but if your crew is working with or around chemicals, then you may need to rent one. If you need one on your worksite, give us a call and we can find one to bundle with your other temporary services.

Cleaning and servicing porta potties

The American National Standards Institute recommends cleaning construction portable toilets once per week, or renting additional toilets for the worksite if they can’t be serviced weekly. If you’ve ever seen a porta potty go without service for more than a week, you know why that recommendation is in place.
