Partial Evacuation with a Missing Wheelchair User
At 21:15 a fire alarm activates in a 1,800-capacity venue. The alarm zone indicator shows a fire in a back-of-house store room, not the auditorium. Smoke is visible in the corridor behind the bar. The audience is 1,600 and the show is mid-set. Your evacuation plan designates full evacuation for any alarm, but the incident controller on site says the fire is small and contained and proposes a 'defensive' approach: keep the audience seated, close the bar corridor, and let the fire service handle it. You have 30 stewards, four exits, and one known wheelchair user in the accessible viewing area on the upper level, whose evacuation chair is stored in the back-of-house store room now affected by smoke. The fire service is eight minutes away.
1. Should the audience be evacuated? Reason through the decision using the information available.
Read the worked answer
The starting point is that the plan says full evacuation on any alarm, and departing from a plan during an incident requires strong justification and a recorded decision by the incident controller.
Arguments for evacuating:
- Smoke is visible in a public circulation route (the bar corridor). Smoke spread is the main life risk in a fire, and a 'small' fire in a store room can produce lethal conditions in a corridor within minutes.
- The evacuation chair for the known wheelchair user is stored in the affected store room. That alone means the accessible evacuation plan is compromised.
- 1,600 people mid-show take time to move; waiting for the fire service to arrive and then deciding to evacuate loses those minutes.
- The fire service is eight minutes away; the venue must be able to act without them.
Arguments for the defensive approach: a contained fire in a non-public area, and evacuation itself carries risks (crush at exits, weather, re-entry).
Balanced judgement: the presence of smoke in a public route and the loss of the evacuation chair tip the decision towards evacuation of the affected zone at minimum, and in practice full evacuation, because the plan requires it and the conditions are not clearly stable. A phased evacuation - starting with the bar corridor and adjacent zones, then the auditorium - is a defensible middle course, but only if it is announced, timed, and the controller accepts responsibility for the deviation in writing.
2. How do you handle the wheelchair user on the upper level, and what do you do about the stored evacuation chair?
Read the worked answer
The evacuation chair is in a smoke-affected room, so the planned means of assisted evacuation is unavailable until proven otherwise. Do not send a steward into a smoke-filled store room without breathing apparatus.
Actions:
- Do not leave the wheelchair user waiting. Assign two stewards immediately to stay with them and move them to a protected area - a fire-rated refuge or stairwell lobby with clear communication - as a first step.
- Find an alternative: check whether a second chair exists elsewhere, whether the fire service can assist on arrival, and whether a ground-level route exists. If the upper level has a protected stair and the user can transfer, a manual carry by trained staff is a last resort with documented risk.
- Tell the fire service on arrival exactly where the person is and that the chair is in the affected room.
- Record the decision, the location, and the staff assigned.
The professional point is that accessible evacuation must never depend on a single item stored in a single location; the failure here is a planning failure that the incident exposes, and the response must not leave the person to be 'dealt with later'.
