Personal air sampling and employee interviews were conducted on February 9, 1977, and March 1, 1977, to evaluate worker exposures to zinc-oxide (1314132), resorcinol (108463), formaldehyde (50000), sodium-hydroxide (1310732), and ammonia (7664417) during the manufacture of high pressure hose at the Gates Rubber Company (SIC- 5199) in Denver, Colorado. The survey was requested by company management on behalf of 40 employees. One of ten sodium-hydroxide samples exceeded the threshold limit value of 2 milligrams per cubic meter. Zinc-oxide, formaldehyde, ammonia and resorcinol samples were all below evaluation criteria. The author concludes that a health hazard existed from a combination of low exposures to zinc- oxide, resorcinol, formaldehyde, ammonia and rayon (61788770) fibers as well as from exposure to sodium-hydroxide. The author recommends that ventilation be installed in the braided hose department, that employees be provided with barrier creams for protection, and that physicians treating the employees be informed of worker exposures and work conditions.
