Chemical Hygiene Plan

Policy Statement

Introduction:

Hazardous chemicals are a vital tool in teaching and research. The risks of exposure, fire/explosion and injury can be managed with training, planning and the proper equipment. This plan is intended for experienced scientists and will help them mentor new researchers. Competency in the lab can be achieved through training, observation and supervision. This guide is a reference to that end.
