The 03:20 Alarm on the Fourth Floor
You are the lobby guard in a 12-storey, 240-unit residential building. At 03:20 the fire alarm sounds and the enunciator shows a smoke detector in the fourth-floor east corridor. You see no smoke in the lobby. On the fourth floor you find a faint burning-plastic smell and light haze but no visible flame. In 411 a resident refuses to come out, saying she is waiting for a phone call. One second-floor stairwell door has been wedged open with a rubber wedge. The elevator is still running, and about 30 residents are now standing in the lobby asking you what is happening. You are the only staff member on site.
1. Give the order in which you take action for the first ten minutes, and explain why that order.

1. Confirm and transmit the alarm. The building's alarm may or may not be monitored. Verify that the signal actually reached the fire department; if you cannot confirm it, call 911 yourself and say 'fire alarm activation, fourth-floor east corridor, haze and a burning-plastic smell, 240-unit residential building'. Everything else is worthless if nobody is coming.
2. Life safety, not investigation. Do not go looking for the source in a haze-filled corridor. You are not trained, equipped, or authorized to fight fire. Stay out of smoke; smoke kills faster than flame and the corridor is the escape route.
3. Remove the barriers. Take the wedge out of the second-floor stairwell door - a propped fire door defeats the compartmentation the whole building depends on. Put the elevator on lobby recall/fire service and tape it off so no one rides it.
4. Direct people to the stairs. One clear voice at the stairwell: 'Stairs, down, out the front door, stay clear of the building.' Residents evacuating through smoke-free stairs beats a lobby crowd.
5. Meet the fire department at the entrance with the enunciator panel location, the affected zone, and the key or access code.
Order matters because notification and evacuation protect 240 people; investigating protects nobody.
2. What do you do about the resident in 411 and about the running elevator?
Read the worked answer
The resident in 411
- Tell her clearly what is happening and what the alarm means; people refuse because they do not understand, not always because they are stubborn.
- You have no authority to remove a competent adult from her own home by force. Physically dragging her out is an assault, and a struggle in a corridor delays everyone else.
- Give the fire department her exact unit number and her reason for refusing when they arrive. Firefighters have the authority and the equipment to deal with it.
- If she is unable to understand or to evacuate herself (cognitive impairment, mobility limitation), say so explicitly on the handover - that changes the fire department's priorities.
- Record the time, what you said, and her words.
The elevator Out of service. In a fire, elevators can open on the fire floor, and they can dump occupants into smoke; a power failure or a false call strands people in a box. Recall it to the lobby, keep the doors open, and post a physical barrier or your own presence so residents do not choose it out of habit.
The 30 people in the lobby Give them a single, short, repeated instruction and a reason. An informed crowd self-organizes; an ignored crowd turns into the second emergency.
3. How do you decide between evacuating and defending in place, and what do you record?
Read the worked answer
The decision Defend-in-place depends on the building design - compartmentation, sprinklers, smoke control - and on the fire department telling you so. It is never the guard's unilateral call. Here you have three signals that argue for moving people out of the affected zone: an activated detector, visible haze, and a burning-plastic smell on the alarm floor. Light haze can precede a fast-developing fire, and a plastic smell means the products of combustion are already in the corridor. At minimum, evacuate the alarm floor and the floors above and below; on a residential overnight alarm with 240 units, evacuating the building is the safer default and the fire department can stop it.
What you record
- Time the alarm sounded, time you confirmed transmission, who you spoke to at 911.
- Zone and floor shown on the enunciator, and exactly what you saw and smelled - describe, do not diagnose ('light haze, plastic odour', not 'small electrical fire').
- Each floor or area you cleared, and which you did not.
- The wedged door: which stairwell, which floor, and that you removed the obstruction.
- Elevator recall time.
- Unit 411: the refusal, your words, her words, and that the fire department was told.
- Time the fire department arrived and the name of the officer you handed over to.
The report is written for the fire investigator and for the building's insurer, and it is the only record of what the building looked like before the fire department arrived.
