The Control of Substances Hazardous to Health (Amendment) Regulations 2004 were published in December.
The main change is to do away with maximum exposure limits (MELs) and occupational exposure standards (OESs), replacing these with new workplace exposure limits (WELs). An updated edition of EH40, the document that sets out the exposure limits, will be produced in time for April 2005 when the new standards take effect. It is hoped that the single standard will eliminate many of the misunderstandings that were caused by having a two-tier system.
The existing duty to review control measures at suitable intervals has been expanded. Employers will have an explicit obligation to review their systems of work, and the effectiveness of supervision, as part of keeping the COSHH assessments up-to-date.
