Science Experiment/STEM Activity Risk Assessment

Typical hazards & measures

• Chemical spills — Keep spill containment kits available and train participants on how to safely contain and clean up spills. Handle chemicals in areas lined with protective spill trays. Label all chemical containers clearly to minimize confusion and accidents.
• Allergic reactions to materials — Obtain allergy information from participants beforehand. Provide alternative materials for those with allergies and ensure all participants wear gloves when handling potential allergens. Have first aid supplies and allergy treatments readily available.
• Heat exposure from Bunsen burners — Ensure students tie back long hair, use heat-resistant gloves, and place Bunsen burners on stable surfaces. Clear the area of flammable materials, and provide training on how to properly light and extinguish burners. Supervise all open flame activities closely.
• Ingestion of harmful substances — Label all containers clearly and enforce strict hygiene rules, including no eating or drinking in the lab. Provide training on the dangers of ingestion and ensure that any mouth-contacting experiments use safe, non-toxic materials.
• Inadequate supervision — Maintain appropriate adult-to-participant ratios, based on the complexity of the activity. Ensure all supervisors are trained in both the experiment protocols and emergency procedures. Regularly monitor and intervene to prevent unsafe behaviors or misuse of equipment.
