Risk assessment

Hazards and risks

All experiments should be risk assessed to identify the hazards and minimise risks. Always follow teacher instructions and safety advice.

One way to do this is to use a table to identify the hazards, state the risks and suggest how to minimise the risks.

Take, for example, the practical for investigating whether an increase in the size of a solar panel increases the size of the voltage produced. This would involve shining a lamp on a solar panel from a fixed distance and measuring the voltage produced from a voltmeter.

The risk assessment for this experiment might look like this:

LampBurningBe careful not to touch lamp when on. Turn off lamp between uses.
Electric components ShocksCheck wires for bare ends, discard if found. Complete circuit before switching on lamp.
