HSE Researchers Develop Methods for Determination of Isocyanic Acid and Methyl Isocyanate

Published October 10, 2012

Researchers from the U.K.’s Health and Safety Executive (HSE) recently developed a modified method of detecting and quantifying isocyanic acid (ICA) and methyl isocyanate (MIC)—low molecular weight isocyanates—in workplace air samples. According to the report, ICA and MIC “are produced by thermal degradation of isocyanate-derived polyurethanes at high temperatures,” such as during the machining of polyurethane-painted parts in a motor vehicle repair shop or during the flame bonding of polyurethane foams. The authors recommend that the methods described in the report be applied to “suitable samples” to enable HSE to better assess the contribution of IAC and MIC to the total concentration of isocyanates in workplace air.
