• Description:
  Exposure to toluene (108883) as a result of isocyanate sampling was investigated. The personal sampling method for isocyanate sampling involved the use of a toluene based solution in a midget impinger. Three field situations were studied: a wire enameling operation where the average background toluene concentration was less than (mean concentration 8.6mg/m3), and an open shop in which a worker applied an isocyanate compound to a fiberglass pipe producing exposures to toluene of 10mg/m3 for the sampling period. None of these levels was expected to cause adverse health effects; however, some workers have complained of eye irritation. Data collected in a mold floor crane cab indicated a 189mg/m3 8 hour time weighted average exposure to toluene, suggesting that significantly higher toluene levels resulted when toluene vapor was prevented from dissipating due to the confines of the workspace and lack of mechanical exhaust ventilation systems. An open workspace and the mobility of workers made overexposure far less likely to occur. Potential exposures in confined spaces could be easily and quickly predicted using the vapor pressure method. Use of this technique was described. [Description provided by NIOSH]
