When it comes to fire safety, every second counts. Having the right fire suppression tools readily available can mean the difference between a small accident and a devastating disaster. One of the most overlooked yet incredibly effective fire safety tools is the fire blanket. Whether you’re at home, in a commercial kitchen, or managing an industrial site, a fire blanket can be a lifesaver.
In this blog post, we’ll explore everything you need to know about fire blankets, including what they are, how they work, when to use them, and why they should be a part of your fire safety plan.
What Is a Fire Blanket?
A fire blanket is a safety device designed to extinguish small fires at their early stages. It consists of a sheet of fire-resistant material—usually woven glass fiber, Kevlar, or wool treated with flame-retardant chemicals—that can be placed over a fire to cut off its oxygen supply.
The primary goal of a fire blanket is to smother flames and prevent them from spreading. Fire blankets are commonly used in kitchens, workshops, laboratories, and even residential homes to combat Class A (ordinary combustibles) and Class B (flammable liquids) fires. They can also be used to wrap around a person whose clothing has caught fire.
How Does a Fire Blanket Work?
Fire needs three elements to continue burning: heat, fuel, and oxygen. This trio is often referred to as the fire triangle. A fire blanket works by removing oxygen from the equation. By covering the fire with a blanket made of flame-resistant material, it starves the fire of oxygen and effectively extinguishes the flames.
Here’s how the process works:
-
Deployment: Fire blankets are typically stored in quick-release containers or pouches that can be mounted on walls. In an emergency, you simply pull the tabs to release the blanket.
-
Application: You then place the blanket over the flames, covering the fire completely.
-
Smothering the Fire: Once covered, the blanket blocks oxygen from reaching the fire, which suffocates the flames.
-
Cooling: Some materials used in fire blankets also help to cool the surface underneath, minimizing the chance of reignition.
Materials Used in Fire Blankets
The effectiveness of a fire blanket depends on the material used to make it. Most modern fire blankets are made from:
-
Fiberglass: This is the most common material due to its high resistance to heat and non-flammable properties.
-
Wool (with flame-retardant treatment): Often used in fire blankets designed for industrial or heavy-duty use.
-
Kevlar: Used in high-performance blankets where both heat resistance and durability are critical.
These materials are specially treated to resist ignition and to withstand extremely high temperatures—often up to 900°C (1652°F) or more.
When Should You Use a Fire Blanket?
Fire blankets are best suited for small fires that are still manageable. Here are common situations where a fire blanket can be effective:
-
Kitchen fires: Such as grease fires on a stovetop or in a pan.
-
Electrical fires: Covering small appliances or outlets that have caught fire.
-
Clothing fires: Wrapping a person in a fire blanket can help extinguish flames and prevent further injury.
-
Camping or BBQ fires: Containing small outdoor fires or embers.
Do NOT use a fire blanket on:
-
Large, uncontrolled fires: Instead, evacuate and call emergency services.
-
Metal fires: Such as burning magnesium or titanium. These require specialized extinguishers.
-
Fires in confined electrical cabinets: Fire blankets cannot penetrate enclosed areas.
How to Use a Fire Blanket Properly
Using a fire blanket may seem straightforward, but proper technique can ensure its effectiveness and minimize personal risk.
Step-by-Step Guide:
-
Pull the tabs: Most fire blankets are packed with quick-release handles or tabs. Pull them to release the blanket.
-
Protect your hands: Wrap the top edges of the blanket around your hands to shield them from heat and flames.
-
Approach slowly and calmly: Move cautiously toward the fire, keeping the blanket between you and the flames.
-
Cover the fire: Lay the blanket gently over the fire, completely covering it. Do not throw or flap the blanket.
-
Turn off the heat source: If it’s safe, turn off the gas or electrical supply.
-
Leave the blanket in place: Keep it over the fire for at least 15-30 minutes to ensure the flames are completely extinguished.
-
Call emergency services: Always report a fire, even if it seems to be under control.
Benefits of Using a Fire Blanket
Fire blankets offer several advantages as part of your emergency fire equipment:
-
Quick and easy to use: No special training required.
-
No mess or residue: Unlike fire extinguishers, fire blankets don’t leave chemical residue behind.
-
Safe for people: Ideal for clothing fires and for individuals who panic and cannot use a fire extinguisher properly.
-
Compact and portable: Easy to store and carry, making it suitable for homes, cars, boats, and travel.
Where Should You Keep a Fire Blanket?
To maximize its effectiveness, place your fire blanket in accessible and visible locations, such as:
-
Kitchen walls (near but not above the stove)
-
Workshop or garage areas
-
Near fire-prone electrical equipment
-
Camping or BBQ setups
-
In vehicles or boats
Mount the fire blanket in its pouch or container where it can be easily pulled out during an emergency.
Fire Blanket Maintenance and Replacement
Just like any other fire safety equipment, fire blankets require periodic inspection. Here are some tips:
-
Check for damage: Look for fraying, tears, or burns.
-
Verify the packaging: Make sure the quick-release tabs and pouch are intact.
-
Follow manufacturer guidelines: Replace as recommended (typically every 5-7 years), even if unused.
-
Never reuse a fire blanket after it has been deployed.
Fire Blanket vs. Fire Extinguisher: Which Is Better?
Both have their roles in fire safety, and ideally, you should have both available.
| Feature | Fire Blanket | Fire Extinguisher |
|---|---|---|
| Best for | Small fires, cooking fires, clothing | Larger fires, electrical & chemical fires |
| Usage | Simple, no training needed | Requires some familiarity |
| Maintenance | Minimal | Regular checks and servicing needed |
| Residue | None | Can be messy (powder, foam, CO2) |
Use a fire blanket for quick smothering, especially in kitchens or when dealing with people. Use a fire extinguisher when the fire is larger or more aggressive.
A fire blanket is a low-cost, high-value tool that should be part of every home and workplace fire safety kit. It’s an excellent first line of defense against small fires and offers peace of mind knowing you’re prepared for unexpected emergencies.
Don’t wait until it’s too late—equip your space with a fire blanket, learn how to use it, and regularly review your fire safety protocols.
