ACGIH® Recommended TLVs for Methyl Methacrylate
In response to recent announcements by American Conference of Governmental Industrial Hygienists (ACGIH), MPA comments to ACGIH supporting the recommended Threshold Limit Values (TLVs) for Methyl Methacrylate (MMA). These limits are consistent with occupational exposure limits set by the European Union SCOEL (Scientific Committee on Occupational Exposure Limits). However, two statements concerning potential respiratory and skin sensitization have been included that are not supported by a wider evaluation of the literature, and could lead to misunderstanding by ACGIH’s intended audiences.
