National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

An Industrial Hygiene Study of Polyurethane Foam Insulation Application Activities at Thermal Acoustic Foam Insulation, Inc., Columbia, MD.

PB81239899

Publication Date	1980
Personal Author	Reisdorf, R. P.; Carese, A. A. A .
Page Count	27
Abstract	Worker exposures to 4,4'-diphenyl methane diisocyanate (101688) (MDI), fluorotrichloromethane (75694) (FTM), alpha-methyl styrene (98839), dimethylethanolamine (108010), dimethylcyclohexylamine (98942) (DMCH), dimethyltin dicarboxylate, carbon monoxide (630080) (CO) and noise at Thermal Acoustic Foam Insulation, Incorporated (SIC-3079) in Columbia, Maryland were surveyed on November 19 and 20, 1979. Concentrations of MDI, FTM, DMCH and CO were detected in the workplace, however all samples were below respective OSHA criteria of 0.02ppm for MDI, 1000ppm for FTM, and 50ppm for CO; standards for FTM were not provided. All other chemical concentrations were below the limit of detection. Noise exposures did not exceed the OSHA standard of 90 decibles relative to the A-weighted scale. The authors conclude that workers at this company are not exposed to any significant health hazards. They recommend that the air compressor be removed from the equipment truck when an employee will be inside the truck for an extended period of time, and that a hearing conservation program, including audiometric testing, be implemented.
