ANSI Standards

As the voice of the U.S. standards and conformity assessment system, the nonprofit American National Standards Institute (ANSI) oversees the creation, promulgation and use of thousands of norms and guidelines that directly impact businesses in nearly every sector of commerce. Many trade associations work with ANSI to set standards in the areas of expertise.

The PSAI is an ANSI-accredited standards developer. Generally, anyone who identifies a need for standardization related to our organization's mission can submit a request to us. Our staff researches the idea to assess whether there is interest, tries to discover if similar standards exist in other organizations, and assesses where the activity would appropriately fit within our strategic priorities. PSAI staff does not determine which standards should be developed; our Standards and Guidance Committee does that. You can review our standards development procedures here.

If you are interested in becoming involved in standards development for the portable sanitation industry, please contact Karleen Kos.

The PSAI has published two standards concerning the number and placement of portable units, hand washing stations, and requirements for related equipment. The standards are free for members. Click the links below to login and access the standards. For nonmembers, the standards are available for purchase through PSAI by clicking here.

In 2021 we will be revising the standards below. If you are interested in their content, we invite you to provide feedback during the public comment period which will be announced on this web page, among other locations, later in the year. If you or the organization you represent is directly and materially affected by the standards, please contact us to learn about participation in the consensus body described in the  standards development procedures posted on this page.

ANSI/PSAI Z4.3 Sanitation – Non-sewered Waste – Disposal Systems – Minimum Requirements

This standard applies to sanitary waste disposal systems for all places of employment where such systems are not connected to a sanitary sewer, septic tank, or on site sewage disposal treatment facility. Its purpose is to assure that employees who don’t have access to indoor sewered toilets are provided with healthful and adequate alternatives.

ANSI/PSAI Z4.4 Sanitation – In Fields and Temporary Labor Camps – Minimum Requirements

This standard prescribes minimum environmental health requirements for camps (whether temporary or permanent) for temporary labor and for field sanitation. The purpose is to protect the health of these workers and, indirectly, the health of the public who may consume agricultural produce from these fields.
