An Industrial Hygiene Study of Polyurethane Foam Insulation Application Activities at Thermal Acoustic Foam Insulation, Inc., Columbia, Maryland.
NIOSH 1980 Jun:23 pages
Worker exposure to air contaminants and noise associated with the application of polyurethane (9009545) foam insulation was determined at Thermal Acoustic Foam Insulation, Inc., in Columbia, Maryland on November 19 and 20, 1979. The survey was conducted at an application site as part of an industry wide industrial hygiene characterization of thermal insulation manufacturing and application. Personal samples were collected for diphenylmethane- diisocyanate (101688) (MDI), dimethylethanolamine (108010), dimethylcyclohexylamine (98942), fluorotrichloromethane (75694), alpha-methyl-styrene (98839), dimethyltin-dicarboxylate, and carbon- monoxide (630080). Employees were not exposed to chemical air contaminants in excess of OSHA standards. The NIOSH recommended limits for noise exposure (90 decibels relative to the A-weighted scale) were exceeded during a nonroutine malfunction inside a truck near an air compressor. The authors recommend that the compressor be removed from the truck when conditions require the presence of an employee inside the truck for extended periods. An effective hearing conservation program with audiometric testing also should be implemented.
