Hazardous Area Installations:

America: Div 1, Zone 0 (Cont. hazard), Zone 1 (Intermittent Hazard), Div 2 or Zone 2 (Hazard under abnormal conditions)

CENELEC (Europe): Zone 0 (continuous), Zone 1 (Intermittent), Zone 2 (abnormal conditions)

Australia: Follows both (depends on the consultants – but mainly European)

Australian Exposure Standards for Atmospheric Contaminants in the Occupational Environment NOHSC: 3008 (1995) has set some TWA standards which are followed by various OH&S Statutory Bodies as well as referred by Standards (AS 1668.2 etc) – some typical TWA (for others refer to USA-ACGIH, OSHA, NIOSH)

NH3: TWA – 25 ppm, STEL – 35 ppmCO2: TWA – 5000 ppm, STEL – 30000 ppmCO: TWA – 30 ppm, STEL- 200 ppmH2S: TWA – 10 ppm, STEL- 15 ppmNO2: TWA – 3 ppm, STEL – 5 ppmNO (Nitric Oxide): TWA - 25 ppmN2O3 (Nitrous Oxide): TWA - 25 PPM (hospitals)Cl2 (Chlorine): TWA – 1 ppmO2 (Oxygen): 19 % Vol (minimum), Air has 20.9 % O2O3 (Ozone): TWA – 0.1 ppm
