Walk-through survey report of Vapor Products, Incorporated, Orlando, Florida, report no. IWS-125-20.
NIOSH 1983 Jul; :1-22
A walkthrough survey was conducted on May 17, 1982 at Vapor Products, Incorporated (SIC-2879), Orlando, Florida, to determine the extent of worker exposure to formaldehyde (50000) and to evaluate an experimental procedure for quantification of formic-acid (64186) in urine. Personal and area air samples were collected and analyzed for formaldehyde. Urine samples were collected from several employees before and after shift work, and formic-acid concentrations were determined. The time weighted average exposure concentrations in breathing zone air samples ranged from less than concentration in area air samples ranged from 0.28 to 3.40ppm. The procedure used to quantify formic-acid in urine had excessively wide variation between replicate analyses, and the results were not reported because they were considered invalid. Personal airborne exposures were well below current OSHA standards of 3ppm for an 8 hour time weighted average, 5ppm for a ceiling value, and 10ppm for a peak excursion, but some were above the 1ppm concentration formerly recommended by NIOSH to protect workers from the irritant effects of formaldehyde. The authors recommend changes in the ventilation system and modification of work practices in the rework and cleanup area to avoid paraformaldehyde (30525894) dust exposure.
