y Executive (HSE) alerted users today to the fact that the hazard classification for trichloroethylene, more commonly referred to as 'trike', is in the process of being changed. It urges them to plan ahead for the tighter requirements in prevention and control measures that this could entail. Trike is used in a large number of workplaces, particularly as a powerful solvent for removing grease. It is often used in vapour degreasing tanks for the cleaning of metal parts. It is also used as a solvent in certain adhesives and chemical processes. The current human health hazard classification for trike under the EU Dangerous Substances Directive, places it in the lowest category (Category 3) of carcinogen (a substance that may cause cancer). Following recent European discussions, it was agreed that this classification be upgraded to a Category 2 carcinogen. HSE plans to implement this change in Spring 2002 (with some transitional arrangements). The effect of this reclassification will be to bring trike within the scope of tighter controls for both worker protection, through the Control of Substances Hazardous to Health (COSHH) Regulations, and the environment (the Solvent Emissions Directive). John Thompson, Head of HSE's Chemicals Policy Division, said: "I urge users to review their arrangements for working with trike, not only in the short term but in the long term as well. Don't act in haste now, or you may need to change again. Seek specialist advice if necessary. Suppliers should also start planning ahead for the change in formal hazard classification."HSE wishes to draw attention to the main factors that trike users need to consider as a result of the change. Whether trike is used as a degreasing agent or for another use you should: Look again at the effectiveness of your prevention and control measures; Consider using substitutes as part of your risk management strategy, but be careful not to do this in isolation.
