e a different solvent in an existing vapour degreasing system. Several are available, but engineering modifications might be needed to control vapour. For example, dichloromethane is very volatile and vapour levels can rise very quickly, and some solvents are flammable. HSE is currently reviewing the possible harmful effects of one possible substitute, n-propyl bromide, aiming to provide information to users which will help control the risks from exposure to this substance. It is hoped that the review will be completed later this year.Other possibilities are to use a process which does not involve using solvents, or to prevent objects from getting dirty and only clean objects when necessary. Reducing cleaning requirements can also increase process efficiency.Each alternative will have advantages and disadvantages and you will need to look at individual processes to decide on the best alternative. But any start-up costs are often balanced by longer term savings. Some alternatives include using wet detergent processes before other wet processes such as plating or passivating. AdviceAdvice on good practice for vapour degreasing and possible alternatives is available in a free publication Vapour degreasing (ref GG015) from Envirowise (the Environmental Technology Best Practice programme), tel: 0800 585794; website: www.envirowise.gov.ukEMSImplementing an Environmental Management System (EMS) within your company is the first vital step to identifying where environmental performance can be improved and unnecessary expenditure can be saved.
