In the latest edition of EH40/2005, 13 new or revised WELs were introduced from 17 January 2020.
EH40/2005 has been updated to include the new and revised WELs introduced by the Carcinogens and Mutagens Directive (EU) 2017/2398 amending Directive (2004/37/EC).
HSE has considered the evidence on all outstanding EU limits and will introduce a revised limit for 3 of them.
WELs are only part of COSHH control measures. You must prevent or control worker exposure to all hazardous substances.
In addition, for carcinogens, mutagens and asthmagens, exposure must be controlled to as low as is reasonably practicable (ALARP).
