Risk assessment is the process of estimating the probability of harm from a hazard (the severity of the hazard multiplied by the probability of exposure to the hazard) by considering the process or the laboratory procedure that will be used with the hazard.
Conducting a risk assessment involves estimating the risk and then identifying steps to minimize the risk—reducing the quantity of the hazard being handled, using chemical hoods and protective barriers, devising safe procedures for handling the hazard, and using personal protective equipment (PPE).
All chemistry and science teachers who work with students in the laboratory should know how to undertake and document a risk assessment.
