Portable Toilet Requirements
SPECIAL EVENTS
Proper planning is the key to successful special events and mass gatherings. Studies indicate that adequate restroom facilities have a significant impact on attendance and profitability. Since visual effects make the greatest impression on attendees, special consideration should be given to quantity, placement and service. Because users of the portable restroom facilities determine the quality of service based on both real and perceived conditions, the special events coordinator will want nice, clean, high quality units that are in good repair with vent screens and door locks. Proper service will maintain the condition of the units with regards to the level of waste, the availability of tissue and clean interior. Even if the event is not large enough to warrant pumping service, general housecleaning can make a significant impact on the event.
A bad experience with a portable restroom can affect the users attitude toward the event itself.
Providing too few units can have a major economic impact on promoters and vendors. Providing too many units can cause an excessive expense for the promoters. The following chart provides a guideline in determining the number of portable restroom facilities necessary to provide adequate service for your customers.

CONSTRUCTION
Portable restrooms are the primary sanitation facility for the construction industry. Service is primary. Units must be placed on a hard surface area that is accessible to delivery and service equipment during all weather conditions. Contractors realize that when employees have to leave the job site or walk too far to use restroom facilities it costs money. The average time needs, including travel, to make one off-site restroom usage is for 7 minutes. If you divide a work’s pay plus benefits/hour by 60 minutes you’ll discover the cost for each minute of restroom usage. A University of Missouri-St. Louis Study, “Provision of Sanitation Facilities at Construction Sites, “ calculated that at four types of contraction sites studied in the St. Louis area, contractors earned an 850% return on their investment in portable facilities. Availability of units was important in the study. Every group of seven (7) workers had access to a facility within 100 feet of the group’s central location. Portable units are not only less expensive than permanent facilities but their use improves productivity.
The following table indicates how many portable restroom facilities are needed based on the number of employees:
Minimium Number of Restroom Facilities
# of Employees Minimum # of Restroom Facilities
1-6 1
7-12 2
13-18 3
19-24 4
Over 24 1 addt’l facility for each
addt'l 6 addt’l employee
*CES requirements exceed OSHA requirements
# of Employees Min # of Restroom Facilities
(If serviced twice/week)
1-15 1
16-35 2
36-55 3
56-75 4
76-95 5
Over 95 1 addt’l facility for
each 20 addt’l employees
The occupational Safety and Health Agency (OSHA) requires sanitation facilities at all work sites in the United Staes. PSAI maintains a close liasison with OSHA and other regulatory agencies such as the American National Standards Instriture (ANSI) to assist in the writing, updating and observance of uniform codes and regulations, locally and nationwide.
