      <subfield code="a">The purpose of this study was to evaluate NIOSH Manual of Analytical Methods (NMAM) Method 1020, 2516, and 1018 for the sampling and analysis of chlorodifluoromethane. Chlorodifluoromethane is a chemically inert, non flammable, non explosive gas at standard conditions, which liquifies when subjected to a pressure greater than atmospheric pressure</subfield>
