Fire alarm response and evacuation
Pillar: INCIDENT · Day 60 · 20–30 min deep read · Updated 1970
This lesson is part of the open Guard.Academy library. All content is free to read. Bookmark it, share it with a colleague, and come back to the drills the next time you're on shift.
Opening The first 90 seconds of any incident are yours alone — and almost always decide the next 90 minutes.
Why this matters Most shifts will pass without an incident. The shifts that do contain one will test your training in the first 90 seconds: the period before help arrives. Whether it's a medical, a fire, a missing child or a suspicious package, your first job is to make the scene safer, not to play hero.
A short history Major incident planning in the UK is shaped by hard lessons: Hillsborough (1989) reshaped crowd safety; the Manchester Arena attack (2017) drove Martyn's Law; the Grenfell fire (2017) overhauled fire safety thinking. Each disaster left a body of guidance — the Purple Guide, the Event Safety Guide, JESIP principles — that frontline operatives are now expected to know in plain English.
International context DR ABC and the 30:2 ratio are the international consensus from the Resuscitation Council, AHA and ERC. HOT and Run-Hide-Tell are UK-specific names for principles taught — under different labels — in most developed counter-terrorism programmes.
By the numbers - Average UK ambulance response to a Cat-1 call is 7–9 minutes — the first responder is usually a guard, not a paramedic. - Crowd-related serious injuries cluster at densities above 4 people per m² with restricted movement. - Around 70% of lost-child cases at large events resolve within 30 minutes when boundaries are locked early. - Scene-preservation failures are cited in a majority of unsuccessful prosecutions of in-venue offences.
Numbers to know by heart - 90 seconds — the window before help arrives at most sites. - 30:2 — adult CPR compressions:breaths ratio. - 5–6cm — adult compression depth. - 100–120 — compressions per minute.
The framework Run **SAFER**: **S**top, **A**ssess, **F**ind help, **E**xecute the plan, **R**eport.
Deep dive The first 90 seconds of any incident are yours alone. SAFER — Stop, Assess, Find help, Execute, Report — is the framework, but its real value is that it stops you running into the danger. Stop, breathe, look. Assess what's actually happening, not what you assume is happening. Find help via radio first (control coordinates), then 999 if needed. Execute the most life-saving action you're trained for — and only that. Report cleanly and write it up while it's fresh. Then debrief, formally and informally, with your team and yourself.
On shift — step by step 1. Stop and take a single deep breath before you act. 2. Assess the scene for danger to yourself, the public, and the casualty. 3. Find help via radio, 999, or the nearest colleague. 4. Execute the most life-saving action you are trained for. 5. Report cleanly and write it up while it's fresh.
Real-world scenario A guard at a stadium sees a guest collapse during a concert. He radios control immediately ('Medical, gate B, adult male, unresponsive'), starts a primary survey (DR ABC), and a colleague arrives with the AED within 90 seconds. The early radio call shaved minutes off the response — and the guest is later discharged from hospital.
Scenario walk-through — Lost child at a festival Description first, lock boundary, alert control, reassure parent, search outward in rings. Tannoy only with care — and never broadcast a child's name publicly without thought.
Another scenario — Suspicious package by the bin Apply HOT. If suspicious — clear the area, cordon, report. Never touch, never move, never investigate.
One more — Collapse in the queue Radio, DR ABC, send for the AED, manage the crowd around you, hand over to ambulance cleanly with the timeline.
Case study — Stadium medical, gate B A guard radioed a clear medical call, started DR ABC, and a colleague arrived with the AED within 90 seconds. The patient survived. The radio call shaved minutes off the response — that's the headline lesson.
Case study — The 02:15 alarm A fire alarm went off at a half-full venue. The team treated it as real, evacuated by the practiced routes, and the cause turned out to be a malicious activation. The discipline of treating every alarm as real meant no one rolled the dice.
Myths vs reality **Myth:** Hero first, paperwork later. **Reality:** Hero second. Make the scene safe first; then act; then write.
Myth: 999 is always the right first call. Reality: Control room first when there is one — they coordinate the 999 call and free you to help.
Drills you can run before your next shift 1. Walk your site and identify the nearest AED to each major zone. 2. Run a 60-second 'lost child' drill — what's your first radio message? 3. Practise the HOT mnemonic out loud — speed under pressure comes from over-learning.
Weekly habits - Walk the evacuation routes of your site at least once a week. - Locate your nearest AED at the start of every shift. - Time yourself running a primary survey on a notional casualty. - Review one incident report per week — yours or a colleague's.
Red flags — what to avoid - Multiple guards calling 999 separately — confusion costs minutes. - Crowding the casualty with untrained staff. - Failing to preserve the scene before help arrives. - Speaking to bystanders with phones instead of focusing on the casualty.
Green flags — what good looks like - Single clean radio call to control. - DR ABC started within 30 seconds. - Scene preserved and boundary established. - Hot debrief held before end of shift.
Pre-shift checklist - [ ] Stop and breathe. - [ ] Assess the scene. - [ ] Find help via radio. - [ ] Execute the life-saving action. - [ ] Report and preserve. - [ ] Debrief.
Common pitfalls - Calling 999 yourself when control already has — confusion costs minutes. - Crowding the casualty with colleagues who aren't first-aid trained. - Letting the scene get contaminated before evidence can be preserved. - Forgetting that 'no comment' is the right answer to bystanders with phones.
Frequently asked questions **Q. Do I have to give first aid?** Legally — there's no duty, but most contracts and your own professional standards expect it within your training.
Q. Can I move a casualty? Only if leaving them where they are puts them in immediate further danger.
Q. What about photos for the report? Use the company-issued device where permitted — never your personal phone.
How this compares elsewhere JESIP (Joint Emergency Services Interoperability Principles) gives police, fire and ambulance a shared framework. Your job is to slot into that framework cleanly, not to replicate it.
Notes for supervisors and team leaders After every notable incident, a supervisor's first job is welfare; second is evidence; third is system learning. Skip any of those three and the next incident gets worse.
The law behind it Common law duty of care; HASAWA 1974; Civil Contingencies Act 2004 (major incident framework).
Key terms - **Primary survey** — DR ABC — Danger, Response, Airway, Breathing, Circulation. - **HOT principles** — Used to assess a suspicious item: Hidden, Obviously suspicious, Typical of the environment. - **Scene preservation** — Keeping the scene as found until police arrive — within reason and safety.
Extended glossary - **SAFER** — Stop, Assess, Find help, Execute, Report — the incident response model. - **DR ABC** — Danger, Response, Airway, Breathing, Circulation — the primary survey. - **HOT** — Hidden, Obviously suspicious, Typical — the suspicious item test. - **Cordon** — A perimeter you create to protect a scene or casualty. - **Triage** — Sorting casualties by clinical priority when resources are limited.

Exam-style tips - When in doubt, choose the answer that prioritises calling for help and securing the scene. - HOT and DR ABC are recurring exam favourites — over-learn them.
Reflection prompts - When was your last real DR ABC moment? - Have you ever debriefed an incident properly — or just gone home?
Today's reflection on this lesson Think back to the last shift where you saw "fire alarm response and evacuation" come up. What did you do? What would you change with today's framework in mind? Hold that in mind as you answer the questions below — it's the reflection that turns a lesson into a habit.
Closing thoughts Incidents reward the people who trained for the boring 99% — the slips, the alarms, the lost children. Train the boring ones and the rare ones look after themselves.
