Health & Safety Office (EHS) has developed this manual to assist in the recognition, evaluation, and control of hazards associated with laboratory and chemical operations. This manual also meets the requirements of the International Fire Code, 2012 5001.3 general provision for hazardous materials. It is the responsibility of every lab and chemical user to maintain, to the best of their ability, a safe work environment. This manual is intended to establish baseline safety practices for working with chemicals and working in laboratories. Due to the
