This securing premises during storms, flooding, and extreme weather toolbox talk template provides a comprehensive safety briefing for security teams, facilities managers and public safety officers. It covers high‑wind debris impact, rapid‑rise flood water slip and drowning risks, electrical shock from water‑logged equipment, structural collapse under wind loads, and thermal stress or hypothermia for exposed personnel. The guide references UK legislation such as the Health and Safety at Work Act 1974, the Management of Health and Safety at Work Regulations 1999, the Civil Contingencies Act 2004, and the Workplace (Health, Safety and Welfare) Regulations 1992. It also links to HSE guidance on emergency procedures (HSE emergency procedures) and the Electricity at Work Regulations 1989 (Regulation 7). Practical actions include pre‑storm risk assessments, securing loose objects, installing BS EN 124 flood barriers, safe electrical shutdowns, provision of BS EN ISO 20345 PPE, clear evacuation routes, and post‑event inspections. The template is suitable for corporate campuses, schools, hospitals, transport hubs and critical infrastructure sites and can be customised to site‑specific conditions. Regular review of this toolbox talk ensures that lessons learned from each extreme weather event are incorporated, keeping procedures up‑to‑date with the latest HSE guidance and legislative changes.
