Without knowing more about your situation, its difficult to be specific. It partly depends on how ATE/DSEAR impacts on your business/work activities. At an operator/shop floor level - operators will need to know the results of your risk assessment and what they actually have to do in terms of working practices e.g. safe handling/use of flammable liquids etc Manager/technical level - how to do a DSEAR risk assessment, what the regulations require, recognition of good working/technical practices, what the important issues are - identification of ignition sources, basic chemistry/material properties, understand the technical terms about Flashpoints etc. Understand the ATEX classification system. Understand how to undertake Hazardous Area Classification. BS60079-10 or IP15 Engineer level - the above plus the specific technical specifications and standards relating to electrical equipment, especially. Maintenance and testing requirements. I would suggest you need to do a job safety analysis (JSA) with respect to DSEAR. Send me a message if you would like further help

Tony, agree with previous comments re type & level of training. My previous employer used a company called sira environmental. http://www.siraenvironmental.com/default.aspx I have no idea about the cost of the training, but it was very thorough (even the basic course). PH2
