116 . ROSS A. MC FARLAND In the design of controls, special consideration is given to range, strength, speed, and accuracy of body movements in relation to the design of controls in cluding location, shape, size, direction of movement, and gear ratio. The ad vantages of standardization of equipment are noted. Probably no better illustra tion could be given of the way in which the designer, the safety engineer, and the biological scientist should cooperate in the interest of safety than in the field of display and control problems. The physical variables of the environment are then considered briefly insofar as they relate specifically to the design of the working area. Attributing accidents to human factors has sometimes been overemphasized; often the underlying cause of the accident can be traced to poor or inadequate design of equipment. Under such conditions, the wider use of biological and psy chological data in the design of machines and working areas can contribute sub stantially to accident prevention. To achieve this, however, effective collaboration is necessary between the engineering and biological personnel. ' ' y,f " gfe CHAPTER V Industrial Sanitation M. A. SHAPIRO i|Btiustrial sanitation is essentially a specialized application of community ^^mppmental health services. Within the purview of industrial sanitation are * _ fllprihciples involved in controlling the spread of infection or other insults to the (TrMIS.of the employee that are not inherent in the manufacturing process per se. S^Fpf`'example, the industrial establishment that provides feeding facilities invites l||ljstster of food-borne infections and food poisoning if it fails to supply its ||ees with the utmost in sanitary food-handling facilities and practices. Even lithe industry may contract for these services with an industrial catering fflj it does not absolve itself of this responsibility. ,,l`areas that may be considered the province of industrial sanitation are: jffovision of a safe, potable, and adequate water supply; (2) collection and |Fof liquid and solid wastes; (3) assurance of a safe food supply; (4) ^Bd'BlbntHatitimjf'insects'and rodents, especially-those known to be vectors (5) provision of adequate sanitary facilities and other personal serv'maintenance of general cleanliness of the industrial establishment. W" Provision of a Safe, Potable, and Adequate Water Supply ^SOURCE AND REGULATORY CONTROL OF THE WATER SUPPLY Pqe case of very large industries, the facilities for providing a safe and Skater supply rival in size and complexity those of many a community. |"W.nen'water is supplied by the community, it is regulated aB to safety and quality wmiTcimffiii'cipal or state authorities and, in the case of interstate commerce, by ^^EpSal-governmentr-When no-public supply is availBbleiat.an-economic cost, S^^inclusffiiar establishment must of necessity develop an adequate source of its ^^ahvjmsiially it must treat the water at its own facilities to make it potable and Siiie^iiegOntrol measures applicable to public supplies must b,e- observed in the iMm^miai^zpply.
