when would it be appropriate to smother a fire with a fire blanket?
A fire blanket is appropriate when you can safely smother a small, contained fire completely and quickly, without putting yourself in serious danger.
Key situations where it is appropriate
Use a fire blanket to smother a fire when:
- Small cooking/oil (Class F) fires
- A pan of oil or fat that has just caught fire on the hob (shallow frying pan, baking tray, small wok).
* Small burning food on a tray or cooking surface, where the flames are low and localised.
* You can reach the fire without leaning over or through the flames, and the blanket is large enough to cover the whole pan/surface.
- Small surface fires
- Burning food or materials on a worktop, bench, or counter, where the fire area is smaller than the blanket.
* Small fires in a bin or on the floor that are still contained and not spreading rapidly.
- Clothing on fire
- When a person’s clothes catch fire (for example in a kitchen or lab), wrapping them in a fire blanket to smother the flames is appropriate if you can do so quickly and safely.
* The person should be helped to stop, drop, and roll as you wrap the blanket around them to cut off oxygen.
- Very small electrical fires
- Some guidance allows a fire blanket on small electrical fires (for example, a tiny appliance fire) where you can safely cut the power and fully cover the fire.
* Only if the fire is small, accessible, and your blanket can cover it completely.
Conditions that should all be true
It is appropriate to smother a fire with a fire blanket when these are all met:
- The fire is small and contained (not spreading up walls or across the room).
- The fire area is smaller than the fire blanket , so you can fully cover it and seal the edges.
- You can approach safely without passing through flames or heavy smoke.
- You can turn off the heat/power (e.g., hob, oven, appliance) or it is already off.
- You have a clear escape route behind you in case the fire grows.
A simple example:
A shallow frying pan of oil catches fire on the cooker, flames are under the hood height, you can reach from the side, turn off the hob, and your blanket is big enough to cover the pan completely — this is exactly when a fire blanket is appropriate.
When it is not appropriate
You should not attempt to smother a fire with a fire blanket when:
- The fire is larger than the blanket or already spreading to cupboards, curtains, or walls.
- The heat is so intense that you cannot approach without serious risk.
- The fire involves gas, large electrical equipment, or burning metals , which require specialist extinguishers.
- A deep-fat fryer is involved and there’s significant risk of hot oil splashing as you place the blanket (some authorities advise great caution or using specialised lids/extinguishers instead).
In these cases, evacuate immediately , close doors if safe, and call emergency services.
How to smother a fire correctly (short steps)
When it is appropriate to use the blanket:
- Turn off the heat or power if you can do so safely.
- Pull the blanket from its container using the tabs.
- Hold the top corners with your hands behind the blanket as a shield.
- Approach low and carefully, without throwing the blanket.
- Gently place (don’t flick) the blanket over the fire, covering it completely and sealing the edges.
- Leave it in place for at least 30–60 minutes or until firefighters say it’s safe; don’t lift it early, as the fire may reignite.
- Always contact emergency services for any fire you’ve had to fight, even if it appears out.
Simple rule of thumb
- Yes, use a fire blanket : very small, contained, reachable fires (pan of oil, small surface fire, clothing fire) that you can cover completely.
- No, do not use a fire blanket : anything large, spreading, too hot to approach, involving gas or specialist materials — get out and call for help.
