Portable Sanitation Association International

31 2018 INDUSTRY RESOURCE DIRECTORY The American Society for Safety Engineers (ASSE) released an updated version of its ANSI standard for Sanitation in Construction in July 2017, ANSI/ASSE A10.25-2017. It both complements and contrasts with the ANSI standards the PSAI released in 2016. As in its past editions, ANSI/ASSE A10.25-2017 addresses potable water, toilets, and general hand washing facilities on construction sites. The updated ASSE standard is one of a series of safety standards that has been created by the ASSE Accredited Standards Committee on Safety in Construction and Demolition Operations. The series—including A10.25—has been around for many years. Other standards in the series published by ASSE cover topics such as scaffolding, excavation, hot mix asphalt facilities, and emergency procedures for construction sites, among many others. Although ASSE has used the ANSI-mandated consensus process for developing and updating the A10.25 standard on sanitation, the PSAI was not involved in the process—probably because ASSE and the PSAI were both unaware the other was writing a similar standard. Going forward, the PSAI will be involved in updates of ANSI/ASSE A10.25, and we will similarly invite representatives from ASSE to the table when the PSAI's standards need to be updated. Overview of ANSI/ASSE A10.25-2017 ANSI/ASSE A10.25 is a comparatively short, focused document. The standard applies to all construction and demolition job sites, and it addresses potable water, toilets, and hand washing facilities. Here are some notable points from the standard: • The standard references another ANSI standard, the Code of Federal Regulations on drinking water standards, and OSHA standards. 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 standard 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.
