Sound - Risk Assessments

The Primary Science Advisory Service (PZAZ) provides a comprehensive risk assessment for Year 4 lessons on sound, 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 outlines its role in offering advice and resources, such as lesson plans and risk assessments, but clarifies that it is not responsible for any incidents that may arise from the use of this information. The risk assessment includes a disclaimer that PZAZ has taken reasonable care to ensure the accuracy of its materials based on current knowledge.

The risk profile for the sound lessons is categorized as low, with potential hazards identified for pupils, teachers, assistants, and classroom visitors. These hazards range from the risk of eye damage from flicking elastic bands to the dangers of sharp edges on broken tuning forks, pierced skin from bamboo skewers, slips from spilled liquids, germ transmission, cuts from glass, and injuries from noise balloons. Controls are suggested to mitigate these risks, such as wearing safety goggles, careful handling of sharp objects, prompt cleaning of spills, proper disposal of food items, examining glassware for defects, ensuring sufficient space during activities, and protecting those sensitive to loud noises. The assessment also includes precautionary measures for noise-making equipment and a warning system for loose balls on the floor. Specific instructions are provided for the disposal of waste materials, although the assessment does not specify the use of chemicals, biological matter, or mains appliances in the lessons.
