Fire Containment Blankets: How They Work and When to Use Them
Summary:Fire containment blankets smother small fires by cutting off oxygen. They're essential for kitchen fires, workshop safety, and emergency preparedness. Learn proper usage, benefits, and limitations.
What Is a Fire Containment Blanket?
A fire containment blanket is a safety device made from flame-resistant materials like fiberglass or treated wool. When placed over a fire, it starves the flames of oxygen, stopping combustion. These blankets come folded in easy-to-open pouches for quick access during emergencies.
When Should You Use a Fire Blanket?
Fire containment blankets work best on:
- Grease fires (kitchen emergencies)
- Small electrical fires
- Clothing fires
- Waste bin fires
Never use water on grease or electrical fires - this spreads flames. A fire containment blanket is safer than chemical extinguishers for these situations.
How to Properly Use Your Fire Blanket
- Pull the tabs to release the blanket from its container
- Hold the blanket by the protective flaps (never bare hands)
- Cover the fire completely - don't leave gaps
- Leave the blanket in place for 30+ minutes
- Call emergency services if flames aren't out in 20 seconds
Key Benefits of Fire Containment Blankets
Unlike extinguishers, fire blankets:
- Create no messy chemical residue
- Require minimal training to use
- Work on multiple fire types
- Are reusable if undamaged
- Have 5-10 year shelf life
Limitations to Understand
Fire containment blankets aren't suitable for:
- Large fires (bigger than the blanket size)
- Gas line fires (shut off gas first)
- Deep fryer fires (use Class K extinguishers)
Most household blankets measure 1m×1m - sufficient for stovetop fires but not whole-room blazes.
Choosing the Right Fire Blanket
Look for:
- EN 1869 certification (European safety standard)
- Fiberglass material (most durable)
- Quick-release packaging
- Visible expiration date
Place fire containment blankets near risk areas - kitchens, workshops, fireplaces - but not directly above stoves where heat could damage them.
Maintenance Tips
Inspect your fire containment blanket every 6 months:
- Check for tears or discoloration
- Ensure quick-access packaging isn't stuck
- Verify the expiration date
After use, have professionals inspect the blanket before reusing. Even minor damage reduces effectiveness.
Fire Blankets vs. Extinguishers
Fire containment blankets complement extinguishers:
| Feature | Fire Blanket | Extinguisher |
|---|---|---|
| Best for | Small contained fires | Larger spreading fires |
| Training needed | Minimal | Moderate |
| Cleanup | None | Extensive |
For complete protection, keep both a fire containment blanket and ABC-rated extinguisher in high-risk areas.
