Electricity - Risk Assessments

In the context of Year 4 science lessons focusing on electricity, the Primary Science Advisory Service (PZAZ) provides guidance on risk assessments to ensure the health and safety of all participants during practical activities. Teachers are directed to consult resources from the CLEAPSS or SSERC websites for detailed health and safety information, particularly when handling hazardous substances. PZAZ emphasizes that it holds no liability for any incidents arising from the use of its resources, which include lesson plans, CPD videos, and risk assessments. It is made clear that the risk guidance offered by PZAZ is based on careful preparation and the best available information at the time of writing.

The risk profile for electricity lessons is categorised as low, with the primary concern being the safety of pupils, teachers, assistants, and any classroom visitors. Identified hazards include the potential for cells and cell holders to overheat and cause burns if a short circuit occurs, the risk of skin pinching from crocodile clips, and the possibility of cuts from materials with sharp edges. To mitigate these risks, PZAZ suggests a series of controls: ensuring correct cell orientation to prevent short circuits, avoiding contact between crocodile clips with an 'east-west' arrangement, using only zinc batteries, instructing pupils on the proper use of clips, and checking materials for sharp edges before use. The document does not indicate the use of chemicals, biological matter, or mains appliances in the activities, and disposal methods are not specified, suggesting no special requirements in these areas.
