Trichloroethylene

Trichloroethylene is used in a large number of workplaces, particularly as a powerful solvent for surface degreasing for the cleaning of metal parts. It is classed as a category 2 carcinogen, which means it 'may cause cancer.'

Category 1 and 2 carcinogens are subject to specific requirements under COSHH. Employers must first consider whether it is reasonably practicable to prevent exposure to a carcinogen by using an alternative substance or process and, if not, whether it is
reasonably practicable to enclose the process totally.
