This toolbox talk equips security and public‑safety teams with the legal duties and practical steps required when encountering missing or distressed individuals. It covers risk assessment under the Management of Health and Safety at Work Regulations 1999, reporting obligations from the Guardianship (Missing Persons) Act 2017, and de‑escalation techniques aligned with the Equality Act 2010. The guide details the use of BS EN‑standard personal alarms, BS EN 12644 emergency lighting, and the creation of a secure safe holding area. It also highlights the importance of data protection under UK GDPR, regular scenario‑based drills, and continuous improvement through post‑incident reviews. The procedures should be reviewed annually and after any significant incident to ensure ongoing compliance and continuous improvement. All staff must be familiar with these protocols to maintain a safe environment. The talk also references the Health and Safety at Work Act 1974, the Management of Health and Safety at Work Regulations 1999, and the Fire Safety Order 2005 where relevant, providing step‑by‑step guidance on assessment, communication, documentation, and follow‑up actions. By embedding these practices, organisations can demonstrate compliance during HSE inspections and protect vulnerable individuals. HSE lone‑working guidance, HSE incident response guidance, Guardianship (Missing Persons) Act 2017, Equality Act 2010 provide further detail.
