2、evision of ANSI Z4.3-1995 ANSI American National Standard: For Sanitation Non-Sewered Waste Disposal Systems: Minimum Requirements 4 American National Standard ANSI/PSAI Z4.3-2016 5 Approval of an American National Standard requires verification by ANSI that the requirements for due process, consens
3、us and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached through directly and materially affected interests. Substantial agreement means much more than a s
4、imple majority, but not necessarily unanimity. Consensus requires that all views and objectives be considered and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether
5、s/he has approved the standards or not, from manufacturing, marketing, purchasing or using products, processes or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American Natio

Foreword (This Foreword is not part of the American National Standard Z4.3-2016) The U.S. Public Health Service as Supplement No. 108 to the Public Health Reports in 1933 published the original version of this standard. The American National Stan
13、dard superseded this with standards for a Sanitary Privy, ANSI Z4.3-1935. The American National Standard was revised and expanded several times over the years. The 1987 edition superseded the American National Standard Minimum Requirements for Non-Sewered Waste Disposal Systems, ANSI Z4.3-1979. Wher
14、eas ANSI Z4.3-1935, as its title indicates, was confined to requirements for a sanitary privy, ANSI Z4.3-1987 and additionally with its 1995 edition, was much broader in scope and included all devices now available and acceptable for disposal of human waste where the lack of water or temporary natur
15、e of the installation makes water carriage systems impracticable. The minimum requirements for non-sewered waste disposal systems have taken on much greater importance with the acceptance by the public of clean portable restroom facilities. These facilities, once used primarily on construction proje
16、cts, have become commonplace throughout the American scene, particularly because of the advent of durable plastics in bright colors. They are now found at parks, playgrounds, athletic events and literally any gathering of people that does not have access to permanent toilet facilities. The success o
17、r failure of clean portable restroom facilities is dependent on proper usage. The limited capacity of these units demands proper service. Current standards reflect the most up-to-date human engineering and state-of-the-art deodorizers and procedures. The provisions in this standard are the result of
18、 extended and careful consideration of available knowledge and experience on the subject of non-sewered waste disposal systems and are intended to present minimum requirements recommended for use by employers, property owners, event planners and others. The provisions are also suitable for adoption
19、by governmental administrative authorities. Suggestions for improvement of this standard will be welcome. They should be sent to the Portable Sanitation Association International, 2626 E. 82ndStreet, Suite 175, Bloomington, MN 55425 or to infopsai.org. Consensus for approval of this standard as an A
20、merican National Standard was achieved by use of the Canvass Method.

24、eptic tank or on-site sewage-disposal treatment facility. 1.2 Purpose The purpose of this standard is to assure that adequate sanitary waste-disposal facilities are provided, including but not limited to places of employment, and wherever non-sewered waste-disposal systems are present. 2 Definitions
25、 ADA-compliant: A device that is fully compliant, when properly installed, with the current requirements of the Americans with Disability Act Accessibility Guidelines (ADAAG) as legislated by the Americans with Disabilities Act of 1990. Approved: Approved by the authority having jurisdiction. Black
26、water: Combined domestic effluent including liquid and solid human body waste and the water discharged from toilet usage. Conservation: The preservation and protection of natural resources. Fixture: A device for receiving water and/or waste matter that directs these substances into a sanitary draina
27、ge system. A fixture can include bathtubs, lavatories, showers, sinks, toilets, urinals and water closet bowls. Flush toilet facility: A flush toilet facility is one utilizing a water or non-water flushing fluid that may be deposited into a container or receptacle, or may be re-circulated by a close
28、d system for flushing purposes. Such a facility may be housed in a permanent or portable structure. Grey water: Water that has already been used for bathing, washing, laundry or dishwashing but does not contain human or food waste. Lavatory: A washbowl or basin permanently installed with running wat
29、er, for washing hands, arms, face or head.

Such a facility may be housed in a permanent or
30、 portable structure. Non-sewered waste disposal system: A sanitary waste-disposal system not connected to a sanitary sewer, septic tank or on-site sewage disposal system. Number of employees: For the purpose of this standard, the maximum number of employees present on a regular 40-hour workweek shif
31、t. Permanent: For the purpose of this standard, the term “permanent” means not readily or not easily re-locatable. Portable: For the purpose of this standard, the term “portable” means readily or easily re-locatable. Potable water: Water that is free of objectionable pollution, contamination, minera
32、ls or infection, is approved for drinking, culinary and domestic purposes by the authority having jurisdiction, or in the absence of such authority, water meeting the requirements of the U.S. Environmental Protection Agency. Recycled (reclaimed) wastewater: Water that has passed through a treatment
33、facility mainly for use in irrigation, dust control or fire suppression and is clearly marked “non potable and unsafe for consumption,” therefor encouraging conservation of potable water. 12 2016 by the Portable Sanitation Association International; all rights reserved. Sanitary condition: Within th
34、e meaning of this standard, 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. Tertiary standards: a final stage of water treatment before
35、it can be discharged back into the environment. Toilet facility: A series of fixtures (including showers) maintained within a room for the purpose of defecation, urination, or maintaining personal hygiene. Urinal: A fixture maintained within a toilet facility for the sole purpose of urination. Water
36、 closet: A toilet or fixture, which is designed to receive human waste directly from the user and discharge it to the drainage system. 3 General Requirements 3.1 In places of temporary employment, where ten persons or fewer are employed, a single toilet may be provided for use within a standard 40-h
37、our workweek. See Table 1. 3.2 Toilet facilities shall be installed, maintained and operated in a manner that will not endanger the health or safety of employees or any person using the facility. 3.3 Toilet facilities, with separate fixtures for each gender, shall be provided in all places of employ
38、ment whether indoors, outdoors or underground, except where toilet facilities will be occupied by no more than one person at a time, can be latched from the inside and contain at least one toilet. When these conditions are all met separate toilet facilities for each gender need not be provided (See
39、3.8). 3.4 The number of units to be provided for each gender shall be based upon the number of employees of that gender for whom the facilities are furnished and shall be in accordance with Table 1. Where single-occupancy facilities are equipped with more than one type of fixture, Table 1 Minimum nu
40、mber of toilet facilities Number of Minimum number Employees of toilet facilities If serviced once per week* 1-10 1 11-20 2 21-30 3 31-40 4 Over 40 1 addl for each 10 If serviced more than once per week* 1-15 1 16-35 2 36-55 3 56-75 4 76-95 5 Over 95 1 addl for each 20 NOTE: ”Servicing” refers to th
41、e emptying of waste, the sanitizing of the facility, and restocking of all necessary items. American National Standard ANSI/PSAI Z4.3-2016 2016 by the Portable Sanitation Association International; all rights reserved. 13 only one facility shall be counted for the purpose of Table 1. Where multiple-
42、occupancy facilities are equipped with numerous fixtures (urinals/ toilets), only one fixture in each facility will be counted for the purpose of Table 1. 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 w
43、ith 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
44、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 respon
45、sibility 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 servic
46、ing 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 trans
47、portation 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 fro
48、m 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.” 3.9 Toilet paper with a holder fixture shall be provided for every toilet fixture. An adequate su
49、pply of toilet paper shall be maintained at all times. 3.10 Every toilet shall have a seat made of substantial material having a nonabsorbent finish; this does not preclude a seat molded into the fixture when a urinal is provided. 3.11 Every toilet seat shall be provided with a hinged lid. 4 Permanent Facility Requirements All requirements for permanent facilities are covered under the scope of ANSI/PSAI Z4.1-2016 American National Standard: For Sanitation, In Places of Employment: M
