It is 25 years since the Control of Substances Hazardous to Health (COSHH) regulations came info force.
Risk assessment has always been a cornerstone of COSHH, but one change which is often highlighted is the introduction of control banding – a technique used to guide the assessment and management of workplace risks. Maximum exposure limits and occupational exposure stands were also replaced with workplace exposure limits and the introduction of the principles of good practise as set out in Schedule 2A of the COSHH regulations.
The HSE has a dedicated area called COSHH Essentials, which gives advice on controlling the use of chemicals plus some worked examples and direct advice for some processes, tasks and services. http://www.hse.gov.uk/coshh/essentials/index.htm
