States of Matter - Risk Assessments

The Primary Science Advisory Service (PZAZ) provides a risk assessment for Year 4 lessons on States of Matter, emphasizing the importance of health and safety during practical activities. Teachers are directed to consult the CLEAPSS or SSERC websites for detailed guidance on handling hazardous substances and conducting experiments safely. PZAZ underlines that it is not responsible for any incidents resulting from the use of its resources, which include lesson plans and risk assessments, and that users should exercise their own judgment and care.

Within the risk assessment, various hazards are identified, including the potential for allergic reactions to foodstuffs, cuts from sharp materials, the spread of germs, slip hazards from spills, eye damage from iron filings, irritation from smelling gases and essential oils, and scalds from hot water. The risk profile for these lessons is marked as low. Controls to mitigate these risks include precautions such as careful handling of food for allergy sufferers, inspecting materials for safety, handwashing post-activities, immediate clean-up of spills, the use of safety goggles and surgical gloves, and adult supervision for certain tasks. The use of mains appliances like hairdryers is also noted, with specific instructions for safe operation. Disposal methods for waste materials are provided, ensuring a comprehensive approach to maintaining a secure learning environment for pupils, teachers, assistants, and classroom visitors.
