In the schedules: a new list of maximum exposure limits (new long-term 8h TWA limit for bis(chloromethyl) ether: 0.001ppm = 0.005mg/m3; modified exposure limit for benzene: 5ppm = 16mg/m3); a new list of substances and processes to which the definition of "carcinogen" relates.

Health and Safety - The Control of Asbestos at Work (Amendment) Regulations 1992 [United Kingdom]
These Regulations (entry into force: 1 Jan. 1993) amend the Control of Asbestos at Work Regulations 1987 (see CIS 89-1418), and they implement as respects Great Britain Council Directives 91/382/EEC (see CIS 92-15) and 90/394/EEC (CIS 90-1758). The Regulations redefine the terms action level and control limit. "Action level" is defined as cumulative exposures to asbestos over a continuous 12-week period of 96 fibre-hours/mL of air, when exposure is solely to chrysotile, and 48 fibre-hours/mL of air otherwise. "Control limit" is defined as asbestos concentrations of 0.5 fibres/mL of air (for chrysotile alone) and 0.2 fibres/mL of air when other types of asbestos are present, both averaged over a continuous period of 4h. When averaging is over a continuous period of 10min, the control limit is 3 times the above. The Regulations also make provisions for an obligatory work plan before any work involving the removal of asbestos from buildings or structures, and for emergency action when asbestos escapes into the workplace air at concentrations exceeding the control limit.
