ANSI Z4.3:2016 pdf free download – Non-Sewered Waste Disposal Systems: Minimum Requirements
3.5 Where employees of more than one employer are present at a place of employment (such as, but not necessarily limited to, construction sites with employees of several subcontractors), it shall be the responsibility of each employer to provide toilet facilities sufficient for the total number of their own employees. Where the number of employees at a place of employment fluctuates widely, the number of toilet facilities required should be determined by the maximum number of employees present during a regular 40-hour workweek shift.
3.6 It shall be the responsibility of the employer to ensure that all facilities and fixtures are maintained in a clean and sanitary condition. When toilet facilities require periodic servicing, the responsibility lies with the employer to provide sufficient toilet facilities and servicing to prevent the stated capacity of those facilities from being exceeded and therefore resulting in an unsanitary condition. The employer shall also assure ready access to the toilet facilities by the required servicing equipment.
3.7 Facilities shall be located so as to be readily accessible to the employees for whom they are furnished (See 3.8).
3.8 The requirements of 3.3 and 3.4 do not apply to “mobile crews” or to normally unattended work locations so long as employees working at these locations have transportation immediately available to facilities that meet the other requirements of Section 3. The determination of whether work crews are mobile is dependent upon factors such as worksite operations and circumstances. In general, “mobile crews’” job functions require continual or frequent movement from jobsite to jobsite on an hourly basis. Work crews, whether contracted or sub-contracted, involved in housing construction need to be calculated based on Table 1, and are not considered to be “mobile.”
5.1 Structures housing portable toilet facilities may be mobile trailers or prefabricated, skid-mounted, or otherwise portable unit. If they contain more than one toilet fixture, each fixture shall occupy a separate compartment with a door and walls or partitions between fixtures to assure privacy. Toilet facilities intended for male use shall be equipped with urinals. Urinals do not need to occupy separate compartments.
5.2 The interior floors, walls, ceilings, partitions and doors of all portable structures shall have a finished surface of solid material that can be easily sanitized. It shall be completely enclosed and not transparent from the outside.
5.3 Every portable toilet facility shall provide adequate space for the user with minimum inside dimensions of 91 cm (3 ft) front-to-back and side-to-side, inside clear height of 1 .98 m (6 ft 6 in) and a toilet fixture riser height of 35 to 51 cm (1 4 to 20 in).
5.7 All ADA-Compliant portable facilities must be manufactured in accordance with the most current requirements of the Americans with Disability Act Accessibility Guidelines (ADAAG) There is to be no difference between a permanent or portable facility, including that all necessary equipment must be installed. Every effort must be made to provide the same opportunities for any person with a disability as an able bodied person may have. In order to supply the necessary number of ADA-compliant units for special events and large gatherings, a 5% ratio must be applied to the total number of units rented. That calculated number of units, rounded up to the nearest whole integer must be made available to meet ADA requirements.
