Fire emergencies require immediate, decisive action. There’s no time to second-guess or delay.

Whether in a workplace, commercial building, or shared premises, understanding how to activate a fire alarm and evacuate properly can make a critical difference in protecting lives.

In the event of a fire, there are practical, step-by-step actions to follow, along with essential safety practices that should be part of any building’s fire safety plan. Here's what to do;

 

1 Recognise the signs of fire early

Before anything else, you need to be able to identify a potential fire situation quickly. Common warning signs include:

Smell of burning materials

Visible smoke or flames

Unusual heat coming from a room or appliance

Fire alarm already sounding

If you suspect a fire, do not investigate further. Prioritise safety and act immediately.

 

2 Activate the fire alarm immediately

Fire alarm systems are designed to alert everyone in the building as quickly as possible.

To activate the alarm:

Locate the nearest manual call point (typically a red box mounted on the wall).

Break the glass or press the activation panel, depending on the system installed.

Confirm that the alarm is sounding throughout the building.

Do not hesitate. Early activation gives occupants more time to evacuate safely and can significantly reduce risk.

 

3 Raise the alarm verbally if safe

While the fire alarm system will notify most occupants, verbal alerts can help ensure awareness, especially in smaller or isolated areas.

Shout clearly to warn others nearby.

Direct people toward the nearest exit.

Stay calm and avoid panic, as clear communication helps maintain order during evacuation.

Only do this if it is safe to do so and does not delay your own escape.

 

4 Contact emergency services

Once you are in a safe location, call the fire and rescue services without delay.

Be prepared to provide:

The exact address and location of the fire

Details of the building type (office, warehouse, residential, etc.)

Information about anyone still inside or any known hazards

Do not assume someone else has made the call. If in doubt, make the call yourself.

 

5 Evacuate the building without delay

Evacuation should begin immediately after the alarm is activated.

Follow these key principles:

Leave the building by the nearest safe exit

Do not stop to collect personal belongings

Walk calmly—do not run

Do not use lifts or elevators

Follow illuminated exit signs and emergency lighting

Assist others if it is safe and you are able

Time is critical, so move quickly but in an orderly manner.

 

6 Stay low if there is smoke

Smoke inhalation is one of the greatest dangers in a fire.

Stay close to the ground where air is clearer

Crawl if necessary in heavily smoke-filled areas

Cover your mouth and nose with a cloth to reduce inhalation of smoke

Avoid breathing deeply or directly into smoke

Visibility and air quality can deteriorate quickly, so move efficiently toward exits.

 

7 Check doors before opening

Doors can act as barriers to fire and heat.

Use the back of your hand to feel the door and handle

If the door is hot, do not open it

If it is cool, open it slowly and be ready to close it again if smoke or fire is present

This simple check can prevent exposure to dangerous fire conditions.

 

8 Proceed to the Assembly Point

Once outside the building:

Move immediately to the designated assembly or muster point

Do not re-enter the building under any circumstances

Report your presence to the designated fire warden or responsible person

Assembly points are critical for accounting for everyone and ensuring no one is left inside.

 

9 Do not re-enter the building

Even if the alarm stops, do not assume the building is safe.

Only re-enter when:

Emergency services have confirmed it is safe

An official “all clear” has been given by a responsible authority

Premature re-entry can put lives at risk.

 

10 Maintain regular fire safety awareness

Fire safety is not just about reacting to emergencies—it’s about preparation.

A strong fire safety plan should include:

Regular fire drills

Clear evacuation routes

Visible and accessible fire alarms and extinguishers

Proper signage and emergency lighting

Routine inspections and maintenance of fire safety systems

Training and preparedness help ensure that everyone knows exactly what to do when it matters most.

Regular testing combined with practical training helps reduce risks, improves response times, and ensures your premises are fully prepared should a fire occur.

Fire emergencies demand quick thinking and calm, decisive action. Activating the alarm immediately, evacuating without delay, and following established safety procedures are essential steps that should be second nature to everyone in a building.

Preparation is key. With the right systems in place and proper training, you can ensure that everyone knows how to respond effectively, helping to protect lives and minimise harm when it matters most.
