Consultation Document - Control of Substances Hazardous to Health Regulations
1999 Proposals for Maximum Exposure Limits and Occupational Exposure Standards
Consultation ended 7 June 2002
Summary
The Health and Safety Commission would like your comments on proposals for
occupational exposure limits (OELs) for chemical substances. A form is included
at the back of this booklet to help you do this. It repeats the questions
set out at appropriate points in the text below.
his consultative document contains proposals on 8 different substances
or groups of substances. These are:
- three new Maximum Exposure Limits (MELs) for substances formerly assigned
Occupational Exposure Standards (OESs): chloroethane, hydroquinone and
manganese and its inorganic compounds (1) ;
- withdrawal of five OESs for: glycidyl ethers (2,3-epoxypropyl ethers);
- withdrawal of an OES for subtilisins (proteolytic enzymes as 100% pure
crystalline enzyme);
- withdrawal of an OES for sulphuric acid;
- no change to OES for para-phenylenediamine, but introduction of a skin
notation for this substance; and
- narrowing of the criteria for applying one OES: mineral oil
mists in order to exclude metal working fluids (for which separate HSE
guidance is planned).
