(This note is not part of the Regulations)
1. These Regulations amend the Control of Substances Hazardous to Health Regulations 1988 ("the principal Regulations") by substituting for Schedule 1 to the principal Regulations the Schedule set out in the Schedule to these Regulations. Schedule 1 specifies maximum exposure limits for certain substances which are hazardous to health.
2. The Schedule introduces new maximum exposure limits for benzene, acrylamide, and an additional maximum exposure limit for man made mineral fibres. Amendments are also made to the existing maximum exposure limits for ethylene dibromide, arsenic and its compounds and for rubber fume. One maximum exposure limit, that for 1-methoxy-2-propanol, has been removed from the Schedule.
1974 c. 37; sections 15 and 50 were amended by Schedule 15 to the Employment Protection Act 1975 (c. 71), paragraphs 6 and 16 respectively.
S.I. 1988/1657.
In addition to the maximum exposure limit specified above man-made mineral fibre is also subject to a maximum exposure limit of 2 fibres ml−1, 8-hour TWA, when measured or calculated by a method approved by the Health and Safety Commission.
Limit relates to cyclohexane soluble material.
In addition to the maximum exposure limit specified above vinyl chloride is also subject to an overriding annual maximum exposure limit of 3 ppm
