Briefing temporary security cover about violence and aggression risks

1 September 2026

1 September 2026

A temporary security officer may understand the planned duties but still know very little about the site. Previous incidents, points of tension, support arrangements and reporting routes are all local knowledge. A short, specific briefing gives the officer a clearer picture before the shift begins.

The Health and Safety Executive (HSE) defines work-related violence as any incident in which someone is abused, threatened or assaulted in circumstances relating to their work. That includes verbal abuse and threats as well as physical attacks. This guide explains what a site manager can put into a practical briefing when temporary security cover may face those risks.

Keep responsibility in the right place

Booking security cover does not transfer the site’s health and safety duties to the officer. The responsible employer or dutyholder still needs to assess the risks, decide on suitable controls and explain the arrangements that apply. This article is general guidance and does not replace a site-specific risk assessment or legal advice.

Start with the site’s own risk assessment

HSE says employers must assess significant risks to workers and put effective controls in place, including risks from violence and aggression. The briefing should come from that assessment rather than from a generic script.

Tell the officer about the work situations in which abuse or aggression has happened, or could reasonably arise. Keep the information relevant to the shift. Useful points may include:

  • which planned duties involve contact with customers, visitors, contractors or members of the public;
  • times or work activities that the assessment identifies as higher risk;
  • recent changes to the site, access arrangements or staffing that affect the task;
  • the controls already in place and how the officer is expected to use them;
  • who can provide immediate site support if a situation begins to deteriorate.

A briefing cannot predict every incident, but it can remove avoidable uncertainty. If the site has not reviewed the risk since a change in layout, opening hours, staffing or public access, the booking conversation is a useful prompt to do so.

Agree the role, authority and limits

A vague instruction such as “keep an eye on things” leaves too much open to interpretation. Set out the actual post, the area covered and the decisions the officer may make under site policy. Explain who remains responsible for decisions outside that role.

The briefing should also cover the site’s escalation and emergency procedures. The officer needs to know how to contact the duty manager, how to request assistance and what to do if the agreed controls are no longer enough. Security staff do not have police powers, and the presence of security cover cannot guarantee that an incident will be prevented.

This information should sit alongside the wider site induction for temporary security cover. Keep both briefings consistent so the officer is not given conflicting instructions by different contacts.

Check communication and lone-working arrangements

HSE notes that lone workers may face greater risk because nearby support is limited. It also advises employers to consider communication, staffing levels and arrangements for keeping in touch when controlling violence risks.

If the assignment has one person on duty, do not treat that as a reason to skip the support plan. Confirm the check-in method, who monitors it, what happens after a missed check and how the officer can raise a concern. The site’s risk assessment should decide whether one-person cover is suitable for the particular duties and conditions.

Our guide to one-person security cover for smaller assignments sets out further questions for the booking stage.

Make incident reporting easy to follow

A reporting route is most useful when it is simple enough to use during a busy shift. Name the person or role that receives the first report and provide the correct form, log or system. Explain which matters need an immediate call and which can be recorded at handover.

HSE advises employers to record incidents, review what happened and check whether controls need to change. A basic site report can capture:

  • when and where the incident happened;
  • a concise, factual account of what was seen or heard;
  • any injury, damage or immediate safety concern;
  • the action taken under the site’s agreed procedure;
  • who was informed and whether follow-up is needed.

Some work-related injuries caused by violence are reportable under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR). The responsible business should check the current HSE criteria rather than assume that every incident is, or is not, reportable.

A shift handover should pass on the information the next person needs without turning the log into speculation. See what to record in a security shift handover for a practical structure.

Plan support after an incident

The procedure should not end when the immediate situation is over. HSE advises employers to provide suitable support to workers who experience violence and to consider people who witness an incident as well as those directly involved.

Before the shift, identify who will check on the officer, arrange any required first aid, preserve relevant records and decide whether the risk assessment needs review. Different people can react differently to the same event, so avoid making assumptions about whether someone is fine to continue working.

Pre-shift briefing checklist

  • Confirm the post, hours, duties and areas covered.
  • Share the relevant findings from the current violence risk assessment.
  • Explain the site’s controls, role limits and escalation route.
  • Confirm staffing, check-in and support arrangements.
  • Provide the incident-reporting method and responsible contact.
  • Explain the immediate and follow-up support available after an incident.
  • Record any change that affects the agreed briefing before the shift starts.

The booking details matter too. Our security shift cover request guide explains the basic information to send when making an enquiry.
