Health hazard evaluation determination report: HHE-76-84-377, Kenner Products Company, Cincinnati, Ohio.
Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, HHE 76-84-377, 1977 Mar; :1-11
Acting on a request received from authorized employee representatives, prompted in part by employee complaints regarding breathing problems, coughing and skin irritation, a health hazard evaluation was conducted by NIOSH to evaluate the hazards associated with the use of polyurethane (9009545) foams in the manufacturing of toys (SIC-3944) in building B-1 at the Kenner Products Company, Cincinnati, Ohio, on August 18 to 19 and October 6, 1976. On the basis of air sampling results, interviews of 28 affected employees, including 12 who complained of manifest symptomatology, available toxicity information and discussion with the plant medical department, it is concluded that exposures to toluene-2,4- diisocyanate (584849) and methylene-bisphenyl-isocyanate did not present a health hazard to the employees at the time of the survey. Air sample results for the proprietary amine catalysts, used in the urethane foam systems, likewise did not indicate significant airborne quantities. Small amounts of methylene-chloride (75092), used to clean the injector nozzles, produced significant air concentrations but exposure times were limited so that employee health should not be adversely affected. The company has gone to considerable efforts and expense to develop industrial hygiene and medical programs directed towards the isocyanate exposures in building B-1. It is important that the company continue these programs, paying close attention to all facets thereof. Several other lesser recommendations are given in regard to exhaust ventilation and work practices.
