This Prevent Duty and Radicalisation Awareness toolbox talk equips security, surveillance and public safety staff with the knowledge and procedures required to meet UK legal obligations under the Counter‑Terrorism and Security Act 2015. It outlines how to spot early indicators of extremist behaviour, the mandatory reporting process, data protection requirements and practical steps to support individuals at risk. The guide references official guidance from GOV.UK Prevent duty guidance and the Get help if you’re worried about radicalisation resource. Designed for UK security teams, this 250‑word summary provides clear, actionable advice to protect staff, the public and the organisation while ensuring compliance with health‑and‑safety and data protection legislation. The talk also outlines the role of senior management in overseeing the Prevent duty programme, the importance of regular audits, and the integration of the reporting system with incident management software. It highlights the need for cultural awareness, respecting diversity, and providing support to staff who may experience secondary trauma. Additional links to the official Counter‑Terrorism and Security Act 2015 (Section 26) and the Data Protection Act 2018 on legislation.gov.uk are included to aid further research. By following the steps in this toolbox talk, organisations can demonstrate due diligence, reduce the likelihood of extremist activity, and fulfil their legal obligations under UK law.
