1-BP: A Potential Occupational Hazard
In recent years we have seen an increase in the use of the solvent 1-bromopropane (1-BP) as a substitute for ozone-depleting chlorofluorocarbons and other regulated compounds. 1-BP is used in multiple manufacturing processes, including vapor and immersion degreasing operations to clean electronics and metal and as a solvent vehicle in industries using aerosol applied adhesives such as foam cushion manufacturing. In some states, 1-BP is now being used as an alternative solvent within the dry cleaning industry in response to the restricted use of perchloroethylene, which is considered "probably carcinogenic to humans" by the International Agency for Research on Cancer (IARC).
