An Industrial Hygiene Study of Urea Formaldehyde Foam Insulation Application Activities at Pel Foam Insulation, Inc.
NIOSH 1980 Jun:36 pages
Worker exposures to formaldehyde (50000), furfuryl-alcohol (98000), ammonia (7664417), and respirable dust were determined at Pel Foam Insulation, Incorporated (SIC-1742) in Rockville, Maryland, on September 17 and 18, and December 6, 10, 11, and 12, 1979. The survey was part of a NIOSH industrywide industrial hygiene assessment of thermal insulation manufacturing and application activities. The highest formaldehyde exposures occurred during open bay foam application, where readings of from 1.1 to 2.4 parts per million (ppm) were measured. The OSHA standard specifies an 8 hour time weighted average (TWA) limit for formaldehyde of 3ppm. Furfuryl- alcohol concentrations were below the limit of detection for the sample volumes. No ammonia was detected. The respirable dust concentration while drilling through mortar to inject the insulation was less than the limit of detection for the sample volume. Noise readings were all below NIOSH and OSHA limits. The author recommends use of respirators for appropriate personnel, medical monitoring of exposed workers, and the use of safety glasses or goggles.
