Code of Recommended Practices for Industrial Housekeeping and Sanitation T HIS dode o f recommended good practices for industrial housekeeping and sanitation has been developed by a committee of the American Foundzymen* Association to cover the necessary engineering data and requirements for industrial housekeeping and sanitation, including wash, locker, rest, toilet and lunch room facilities for grayViron. malleable iron, steel and non-ferrous branches o f the foundry industry, and has been approved by the Board of Directors o f A F A j ^ Many foundries have, in addition to casting cleaning departments, pattern, machine and main tenance departments wnich are considered into parts of the foundry operation. Also, in instances there are additional departments wlj in further operations are carried on in the pro ^ ing of materials where this code may be applied. The introduction of a large percentage of f e sale workers in industry, due to die war, nag bro ight some problems that have not heretofore bee 1 of any magnitude. Therefore, this code w ill provide the industry with sufficient data for the minimum requirements o f housekeeping and sanitation facilities for both male and female employees. < The technical committee which prepared this code, known as the American Foundrymen's Association Industrial Hygiene Codes Committee, is composed o f the following: Chairman, Jaa R- Allan, International Harvester Co., Chicago.

No potable water supply system shall be connected to any tank, plumbing or other fixture or device where back sipbozugc may occur to contaminate the water system except in the following manne r: ( 1) Lavatories and Sinks: Where potable waiter supply system is used for wash ing and bathing purposes the outlet of the faucets or the water supply to such lavatories and sinks shall not be less **** one (1) inch above the rim. ( 2) Toilets and Urinals: No potable water system shall be connected to a toilet or urinal except by means of a back flow, preventer provided with the flush valve, or by means ofi s gravity flush tank where the outlet of the potable water system to such * or the critical level of a back} flow pre venter ia at least one (1) inch above the overflow and such overflow shall be capable of handling thei maximum * flow of water without the water level in the thnk reach ing the supply outlet or critical leveL j 4/:) Other Eqmplnent: * No potable water supply shall be directly connected to a( water system] used for purposes that might con taminate the potable water system due to back siphona g e ja u ch as aspirators, syphon*, ejectors, washers, processing l i nks add the like.
