51 2018 INDUSTRY RESOURCE DIRECTORY On the basis of OSHA's guidance and the information in ANSI Z4.3-1995, a portable restroom operator can confidently take the following position related to keeping portable restrooms in "sanitary condition" as per OSHA and MSHA requirements: • The number of restrooms provided must minimally meet OSHA's 1:20 rule. • If servicing occurs at least twice a week under these conditions, the OSHA standard for "sanitary condition" will likely be met. • If servicing will occur only weekly, units should be provided on the ANSI- standard basis of 1 unit per 10 workers. • A unit that is too full or otherwise too unkempt to use does not "count" toward the required number of units. With this in mind, it would benefit portable restroom operators to use decals such as the PSAI's 1:10 worksite stickers to ensure you are visibly stating the capacity of the units. You can also use the above information to help you in sales and quality control conversations with contractors and other employers. The ANSI Z4.3-1995 has undergone two revisions since OSHA provided the guidance above. In the current version, important terms are now defined as follows in ANSI/PSAI Z4.3-2016: "Sanitary condition: […] that physical condition of working quarters which will tend to prevent the incidence and spread of disease. Sanitize: To make free from dirt, infection, disease, etc., by cleaning it. To make something sanitary." Although neither OHSA nor MHSA has yet had occasion to quote from the updated standard Z4.3, we are working toward adoption of these definitions. OSHA OSHA guidance states that a restroom on a construction site that is not sanitary is not considered "available" and therefore cannot be counted toward the OSHA-required minimums.
