Text For Citation: 01 Item/Group: 011 Hazard:

29 CFR 1910.1052(j)(1)(i): The employer did not make medical surveillance available for employees who were or potentially were exposed to methylene chloride at or above the action level on 30 or more days per year, or above the 8-hour time weighted average permissible exposure limit or the short term exposure limit on 10 or more days per year: (a) In the Converting Room, on or about December 14, 2016, a machine operator using C-287 solvent to clean ink off of zingers and rollers on Converting Machine #1 was exposed during a 15 minute sampling period to an airborne methylene chloride concentration of 161.3 parts per million, approximately 1.29 times the short term exposure limit (STEL) of 125 parts per million. This short term exposure limit has been established to protect workers from the acute toxic effects of methylene chloride and its metabolites, which can include adverse effects on the central nervous system, metabolic conversion of methylene chloride to carbon monoxide resulting in adverse cardiac effects, and potential carcinogenic effects. Medical surveillance was not made available for machine operators who may have exposure above the STEL.
