Safety is not just knowing not to stick your hand in a running machine. It's also knowing not to overload outlets, to not use electrical items that are not properly grounded and so on. To assist you in working out a work-site safety program in your office, here are some relevant websites:
From OSHA we have: Office Safety
From the CDC we have: Office Related Safety
From OSU we have: Online Office Safety Library
From the Underwriters Labs we have: Emergency Planning
and for those who are developing safety programs at work here is an excellent source of material including overheads, films, leaflets etc... from SafetyInfo.com
Office safety is often overlooked by many planning safety programs for industrial plants. I hope these links have provided some important information and advice.
