Text For Citation: 01 Item/Group: 025B Hazard: CHEMNEP

29 CFR 1910.1052(c)(2): The employer did not ensure that no employee was exposed to an airborne concentration of methylene chloride in excess of 125 parts per million of air (125 ppm) as determined over a sampling period of 15 minutes: (a)Hill Air Force Base, at 7290 Weiner Street, Hill Air Force Base, UT: On 3/15/11, Hill Air Force Base did not ensure that no employee was exposed to an airborne concentration of methylene chloride in excess of 125 parts per million of air (125 ppm) as determined over a sampling period of 15 minutes. Employees chemically stripped paint from aircraft parts in Building 220 using Henkel Turco 5351 Paint Stripping Agent (containing 30-60% methylene chloride). This process generated methylene chloride aerosol. On 3/3/11 one employee was exposed to methylene chloride at a concentration greater than the 15 minute Time Weighted Average (TWA) Short Term Exposure Limit (STEL) of 125 ppm. The employee was exposed to methylene chloride at a concentration of 456 ppm as a 15 minute TWA. This is 3.64 times the STEL. Air monitoring was conducted for 14 minutes. Abatement Note: Abatement certification and documentation are required for this item (See enclosed "Sample Abatement-Certification Letter").-Certification
