For the named organiser who specifies the protective security design and accepts, in writing, the risk that remains.

What you will be able to do

  • List the laws that apply to the design and the nation for each, kept apart from guidance and from duties not yet in force.
  • Produce evidence of each licence, competence and appointment still needed, or record the gap.
  • Cite an inquiry finding about a plan that existed and was not used, by report, volume and paragraph.
  • Name the responsible person and a deputy, brief staff and record a rehearsal that took place.
  • Prepare for the Terrorism (Protection of Premises) Act 2025 (Martyn's Law) without treating its operational duties as current law.

What the chapters cover

  • The law that applies to the design, and the law that does not yet
  • Preparing for the 2025 Act while its operational duties are not in force
  • Naming the responsible person, briefing staff and rehearsing
  • Specifying the points, the search standards and the people
  • Writing the contractor specification yourself
  • The design paper and the residual risk statement

Thirteen chapters run from who holds the duty to the signed residual-risk statement, with thirteen quick-reference cards you may copy for use at your own event. Worked examples are composite illustrations, not accounts of real events.

Strategic titles are for the named organiser who designs the system across an event or a season and signs the risk that remains. OTAS Live publishes 30 handbooks across ten areas of event work, each at Operational, Tactical and Strategic level.

Three levels in Security and Protective Operations

Each area of event work is covered at Operational, Tactical and Strategic level, so the series follows the job from the post on the ground to the decisions around it.
