W EEKLY EDITION FEBRUARY 13, 2019 Work Site Standards By Karleen Kos, PSAI Executive Director 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 repres entatives from ASSE to the table when the PSAI's standards need to be updated. O ve r vi e w o f A N S I /A S S E A 1 0 .2 5 - 2 0 1 7 ANSI/ASSE A10.25 is a comparatively short, focused document. The standard applies to all construction and demolition job sites, and it addres ses potable water, toilets, and hand washing facilities. Here are some notable points from the standard: • The standard re ferences 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 st andard 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. Comparison with related standards 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 standards 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 tab le that follows will give you a better idea of how these standards compare.* CONTINUED ON PAGE 1 2 PAGE 11
