HSE – EH 40 – Edition 4 – Workplace exposure limits
This has been updated in order to implement amendments to the Carcinogens and Mutagens Directive (2004/37/EC) which introduces or revises 13 binding occupational exposure limit values for a number of carcinogenic substances.
Occupational exposure limits are implemented in the UK via the Control of Substances Hazardous to Health (COSHH) Regulations as Workplace Exposure Limits (WELs) via Table 1 of EH40/2005 ‘Workplace exposure limits' for use with COSHH.
COSHH requires exposure to carcinogenic substances to be reduced to ‘as low as is reasonably practicable'.
IMPORTANT NOTE: The WELs listed in Table 1 of EH40/2005 ‘Workplace Exposure Limits' supersede any limits contained in other HSE guidance or publications.
