One of my lecturer in UNI who worked in SGH is an Ergo expert.
One of the ergo report may cost more than 10k. Seen his Ergo report when I was in a US MNC. Too bad I have read the report after I have completed that module.
EHS consists of Environmental, Health and Safety. Ones need lots of experience to be expert in one of these. I am only a generalist in EHS.
