Fire Blanket FAQ – Use, Sizes, Fire Classes & EN 1869 Explained
Fire Blanket FAQs (EU) – Safe Use, Fire Classes & EN 1869:2019
Fire blankets are one of the simplest and most effective first-response fire-safety tools for European homes, kitchens and professional environments. They extinguish small fires by smothering flames and cutting off oxygen, without chemicals, pressure or technical operation.
This FAQ provides clear, practical answers about fire blanket use, fire classes (including Class F cooking oil fires), sizing, materials, storage and the applicable European standard EN 1869:2019. Where relevant, this page aligns with the European Fire Blanket Reference Specification (EFRS), which provides a formal normative framework for professional evaluation and procurement.
For formal reference documentation, see: European Fire Blanket Reference Specification.
For practical scenario-based guidance, see our pages on kitchen fires, clothing and person fires, candle and living room fires, workplace safety and car, BBQ and outdoor fires.
Safety note: If a fire is growing, smoke is increasing, or the fire cannot be safely reached and fully covered, evacuate immediately and contact emergency services.

Group A – General Questions About Fire Blankets
A.1 What is a fire blanket?
A fire blanket is a fire-safety device made from fire-resistant materials, typically woven fiberglass, designed to extinguish small, contained fires quickly and safely. It works by smothering the fire and cutting off oxygen.
Fire blankets are commonly used in homes, kitchens, BBQ areas and professional environments. In Europe, fire blankets intended for consumer and professional use are manufactured and supplied in line with EN 1869:2019.
A.2 How does a fire blanket work?
A fire blanket works by completely covering the fire, preventing oxygen from reaching the flames. Without oxygen, the fire extinguishes safely and rapidly.
This method is especially effective for cooking-oil fires and clothing fires, where incorrect extinguishing methods such as water can cause escalation.
A.3 When should you use a fire blanket instead of a fire extinguisher?
A fire blanket should be used for small, contained fires that can be fully covered, such as pan fires, cooking-oil fires, small waste-bin fires and clothing fires.
Fire extinguishers or evacuation are more appropriate for larger or spreading fires, or where the fire source cannot be safely covered.
A.4 Are fire blankets suitable for home use?
Yes. Fire blankets are highly suitable for home use because they are easy to operate, require no technical training and cause minimal secondary damage.
A.5 Are fire blankets reusable?
Fire blankets are generally considered single-use after deployment on a real fire. Heat exposure, smoke and residues can compromise performance even if no visible damage is present.
A.6 When should a fire blanket not be used?
Do not use a fire blanket if the fire is too large to cover fully, if you must reach through flames, or if a gas supply cannot be safely shut off. In these situations, evacuate immediately.
Group B – Fire Classes & Performance
B.1 Which fire classes can a fire blanket extinguish?
A high-quality fire blanket can be used to extinguish several fire types by smothering flames:
- Class A – solid materials (wood, paper, textiles)
- Class B – flammable liquids (petrol, solvents, alcohol)
- Class C – flammable gases (only if the gas supply can be safely shut off)
- Electrical situations – small appliance fires where flames can be fully covered
- Class F – cooking oils and fats
B.2 Is a fire blanket suitable for Class F (cooking oil) fires?
Yes. Fire blankets are one of the safest first-response tools for Class F fires. The blanket must fully cover the pan or appliance and be left in place until everything has cooled.
For more practical guidance on this scenario, see our page about fire blankets for kitchen fires.
B.3 Can a fire blanket be used on electrical fires?
Yes, for small electrical appliance fires where flames can be fully covered. Woven fiberglass is non-conductive when used correctly. Switch off power whenever possible.
B.4 What temperature can a fire blanket withstand?
High-quality woven fiberglass fire blankets with a dense weave and 430+ GSM fabric weight are designed for high-temperature fire scenarios.
Premium fire blankets intended for Class F fires can typically withstand temperatures of up to approximately 580 °C.
B.5 Are fire blankets effective on gas fires?
Only if the gas supply can be safely shut off. If gas continues to flow, the fire may re-ignite once the blanket is removed.
Group C – Sizes & Applications
C.1 Which size fire blanket do I need?
- 1 × 1 metre – suitable for most domestic kitchen and pan fires, such as the DVM-FBAG-1x1 or DVM-FBOX-1x1
- 1.2 × 1.8 metres – recommended for wrapping a person and higher-risk environments, such as the DVM-FBAG-1.2×1.8 or DVM-FBOX-1.2×1.8
C.2 Is a 1 × 1 metre fire blanket sufficient for kitchens?
Yes, for most domestic kitchen fires involving pans or small appliances.
C.3 When should I use a larger fire blanket for people?
A larger blanket should be used when a person’s clothing has caught fire. A 1.2 × 1.8 metre size allows full body coverage.
For this application, see our page about fire blankets for clothing and person fires.
C.4 Can a fire blanket be used for BBQ or outdoor fires?
Yes, provided the fire is small and can be fully covered. Wind conditions should be considered.
For more on these scenarios, see our page about car, BBQ and outdoor fires.
C.5 Are fire blankets suitable for cars, campers or boats?
Yes. Fire blankets are compact and effective in confined or mobile environments and should be stored in an easily accessible location.
Group D – Materials & Quality
D.1 What is a fire blanket made of?
High-quality fire blankets are made from woven fiberglass fabric, which is naturally fire-resistant and non-combustible.
D.2 What does 430+ GSM mean?
GSM (grams per square metre) indicates fabric weight and density. Higher GSM generally means better heat resistance and durability.
D.3 Are fiberglass fire blankets safe?
Yes, when manufactured and supplied in accordance with EN 1869:2019 and used correctly.
D.4 Difference between cheap and premium fire blankets?
Premium fire blankets use denser, higher-quality fiberglass and are tested for consistent performance in high-temperature scenarios.
D.5 How long does a fire blanket last?
If unused and stored correctly, a fire blanket can last up to 10 years or longer. Replace immediately after use.
Group E – Storage, Mounting & Placement
E.1 Where should a fire blanket be stored?
Store in a visible, easily accessible location near fire risks but positioned so it can be reached without moving toward the fire.
E.2 Soft pouch vs hard case?
The packaging affects protection and mounting convenience, not fire-safety performance.
E.3 Can a fire blanket be wall mounted?
Yes. Wall mounting improves visibility and response time.
E.4 Are fire blankets suitable for professional kitchens?
Yes. They are widely used for Class F risks and should comply with EN 1869:2019.
E.5 Does packaging affect performance?
No. Performance depends on the blanket itself, not the pouch or case.
Group F – Use & Safety
F.1 How do you use a fire blanket safely?
Pull the tabs, hold the blanket in front of you as a shield, place it carefully over the fire and leave it in place until fully cooled.
F.2 Can a fire blanket be used on a person?
Yes. Wrap gently from shoulders downward. A 1.2 × 1.8 metre blanket is recommended. Seek medical attention immediately.
For this type of emergency, see our page about fire blankets for clothing and person fires.
F.3 What should you do after using a fire blanket?
Leave it in place until cool and replace the blanket immediately.
F.4 Can incorrect use cause burns?
Yes. Burns may occur if the user gets too close, exposes skin or removes the blanket too early.
F.5 Should children be taught how to use a fire blanket?
Children can learn basic principles but should only use a fire blanket under adult supervision.
Group G – Standards, Certification & EU Regulations
G.1 Which European standard applies?
The applicable European standard for fire blankets is EN 1869:2019.

They contain no chemicals or propellants and have a long service life when stored correctly.
H.4 Can a damaged fire blanket be used?
No. Any damaged or contaminated blanket should be replaced immediately.
H.5 How should a fire blanket be disposed of?
Dispose according to local waste regulations. Fiberglass blankets are not suitable for textile recycling.
