11.5 Occupational Exposure Limits
Under this program, long-term exposures to DCM will be kept below 2 ppm (8-hour TWA) and short-term exposures will be kept below 16 ppm (15-minute TWA) wherever possible. Additional monitoring will be implemented whenever long-term exposures exceed the 1 ppm action level. Regulated Areas will be established for any work areas where long-term exposures may exceed 2 ppm (8-hour TWA) or where tasks are performed which may result in short-term exposures exceeding 16 ppm (15-minute TWA).
