Standards Raise the Bar and Inform Construction
Customer Decisions
By Karleen Kos, PSAI Executive Director
• The standard references another ANSI standard, the Code of Federal Regulations on drinking
water standards, and OSHA stand ards. It does not reference the PSAI's standards on similar topics.
• The ASSE standard does include a 1:10 ratio of restrooms to workers as the minimum.
• The standard does not require a specific ratio of hand wash stations to units or workers.
• The stan dard allows exceptions, which permit the use of other devices or methods that will achieve
an equivalent means of sanitation. "Equivalent means of sanitation" is not defined.
• The standard addresses topics not covered in the PSAI's standard, including drinking water on the
work site.

The ASSE standard is just one that decision - makers might turn to for guidance in equipping their job sites. It is
important, then, for you to know how these standar ds compare, and why you should strongly urge your customers
to follow the PSAI's standard ANSI/PSAI Z4.3 - 2016, which covers minimum requirements for non - sewered waste
disposal systems. The table that follows will give you a better idea of how these standar ds compare.*
