This toolbox talk equips stadium security, stewards and first‑aid volunteers with the knowledge to respond swiftly to medical emergencies in crowded stands. It covers recognising cardiac arrest, choking, severe bleeding, heat‑stroke and fainting, and provides step‑by‑step guidance on assessment, calling emergency services, using AEDs, providing first‑aid, maintaining clear access routes and documenting incidents. The content aligns with UK legislation including the Health and Safety at Work Act 1974, the Management of Health and Safety at Work Regulations 1999, and the Safety of Sports Grounds (Designation) Order 2015, as well as HSE emergency procedures guidance and the Sports Ground Safety Authority framework. Practical tips such as using BS EN 149 respiratory protection, BS EN ISO 7010‑labelled first‑aid kits, BS EN 1838 emergency lighting and regular equipment testing ensure compliance and safety. Staff should complete an initial certified first‑aid course and attend annual refresher sessions covering the latest HSE recommendations. Regular weekly inspections of AEDs, kits and lighting are mandatory, with records kept in the safety management system. Quarterly multi‑agency simulation drills with police, fire and ambulance services reinforce communication protocols and ensure rapid, coordinated response. This talk is suitable for football stadiums, cricket grounds and any large‑capacity sports venue and safety. All staff must review this talk annually and sign an acknowledgement to confirm understanding.
