32 2018 INDUSTRY RESOURCE DIRECTORY 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 table that follows will give you a better idea of how these standards compare.* OSHA ASSE PSAI NOTES Units • 1 toilet up to 20 workers • 1 toilet seat + 1 urinal up to 40 workers • Over 200 workers requires 1 toilet seat + 1 urinal per 50 workers • 1 toilet seat + 1 urinal per 10 workers when serviced weekly • Encourages employers to provide units for female use only • Requires the tank have a "secured lid" for storage of waste • 1 toilet facility (which includes a series of fixtures within a room) per 10 workers when serviced at least weekly • 1 toilet facility per 15 workers when serviced more often • Specifies that if employees of more than one employer are present on the site, each employer is responsible for obtaining adequate units for his team • Specifies minimum dimensions, fixtures, ventilation, and other important features required to ensure the user experience is acceptable • PSAI specifies that the ratio pertains to a 40-hour week; the others do not • PSAI places the burden on employers for ensuring the units are clean and sanitary, increasing the incentive to contract for adequate service • OSHA states that toilets in an "unsanitary condition" do not count in meeting the minimum requirements • ASSE allows exceptions Hand Wash Stations • No specific ratio • Standard requires "each lavatory should be provided with" hot/cold or tepid running water, hand soap or a similar cleaning agent, and hand towels or blowers • No specific ratio • Standard requires hand washing facilities "in proximity" to toilet facilities • Requires hand washing facilities to provide potable water, soap, and either cloth or paper towels • 1 station per 10 restrooms on the site • Defines soap and paper towels as "necessary items" • Specifies that hand wash units must be serviced every 45 days with a 10% bleach solution • ASSE requires that hand wash stations use "potable water," but does not recognize the water cannot be maintained as potable in a portable hand wash station • PSAI requires that hand wash stations be clearly marked as containing water "not for consumption" American National Standards (ANS)
