Working with Chemicals

Uni Research has established extensive guidelines on working with chemicals in the HMS / HSE handbook. The following chapter is based on this information, with local adaptations. Please refer to uni.no > intranet > HMS or HSE > sec. 7 working in laboratories > sec. 7.1 for further information, particularly regarding chemical risk assessment. A more generalized approach to risk assessment is found in HMS >sec. 6

Risk Assessment and substitution analysis

When planning a project or experiment, the project leader, together with project participants, must perform a risk analysis of chemicals, reagents, and protocols to be used, before starting work. This risk assessment must be documented and submitted to the Head of Administration. (A standardized scheme for documenting this procedure is found under the Uni Research website.)

Risk = Probability x Consequence

Risk is defined as the probability that a substance or situation will produce harm under specified conditions. Risk is a combination of two factors:

Probabilities and consequences are usually plotted against each other in a matrix to determine the level of risk. An approach to general risk assessment and a matix example is found in the Uni HMS handbook (uni.no > intranett > HMS >sec. 6, risk matrices), see figure below:
