A fire blanket is an essential safety device used to quickly and effectively extinguish early-stage fires by isolating the oxygen supply. Made from fire resistant materials, often as a sheet of woven fabric, fire blankets are widely employed in fire emergencies, such as smothering the flames of grease fires or protecting a person whose clothes have caught fire. In addition to their role in fire safety, fire blankets are versatile, durable, and easy to use, making them a critical part of any fire response plan.
In the United States, fire blankets are particularly valued for their compliance with international standards like EN 1869 and NFPA 701, as well as U.S.-specific certifications such as UL ratings. They complement other fire suppression tools, such as fire extinguishers, and are especially effective for use in homes, laboratories, and industrial environments. Fire blankets are categorized into two main types: Basic Material Fire Blankets and Composite Fire Blankets.
Types of Fire Blankets
Fire blankets come in various types, each designed for specific fire hazards. Basic fire blankets, made from lightweight fiberglass, are ideal for smaller household fires, such as kitchen grease fires or personal safety situations, withstanding temperatures up to 550°C (1,022°F). For industrial settings, high-temperature fire blankets made from high-silica fabric provide enhanced protection, handling temperatures up to 1,000°C (1,832°F), and are perfect for environments like welding or metalworking. For extreme conditions, such as electric vehicle fires or aerospace applications, graphite-coated fire blankets are designed to endure temperatures up to 1,100°C (2,012°F), offering superior protection in high-risk industries. Understanding the type of fire and choosing the appropriate blanket is crucial for effective fire suppression in critical moments.
Are Fire Blankets Effective？
Yes, fire blankets are highly effective — when used for the right types of fires.
They work by smothering flames and cutting off the oxygen supply necessary for combustion. This makes them a fast, clean, and reliable tool to extinguish small fires, especially when dealing with flammable liquids or cooking fires. Fire blankets are particularly well-suited for Class A (solid combustible materials) and Class B (flammable liquids) — as defined by the National Fire Protection Association (NFPA) — though they should never be used on energized electrical equipment (Class C) or metal fires (Class D).
Best Uses for Fire Blankets
Cooking Fires (Grease Fires)
A fire blanket is ideal for handling cooking fires, especially a grease fire, where using water can cause violent flare-ups and oil splatter. Simply placing the blanket over a pot or pan cuts off oxygen and extinguishes the flames without spreading hot oil or leaving chemical residue.In a controlled test, a fire blanket extinguished a burning grease fire at 400°C (752°F) in under five seconds.
Clothing Fires
If someone’s clothes catch fire, wrapping them in a fire blanket can quickly smother the flames. This technique is endorsed by first aid responders and is crucial in both home and workplace fire safety. Fire blankets are commonly found in labs, commercial kitchens, and classrooms for this reason.
Industrial & High-Temperature Environments
In industrial settings, fire blankets made from high-silica fabric or graphite-coated fiberglass offer protection in environments reaching temperatures of over 1,000°C (1,832°F). They’re used in welding operations, battery storage areas, and during hot work procedures to contain sparks and molten debris, reducing fire safety risks. In facilities handling lithium-ion batteries, fire blankets provide a critical layer of defense.
Where Fire Blankets Aren’t Effective
While excellent for extinguishing small fires, fire blankets are not effective for larger fires — such as those consuming entire rooms or involving complex electrical equipment. They should not be used on Class C (live electrical) or Class D (metal) fires, where specialized extinguishing agents are required.
In large-scale emergencies, a fire extinguisher, early evacuation, and contacting emergency services are essential. Think of fire blankets as first-response tools, not full replacements for a fire extinguisher.
Modern fire blankets are manufactured to comply with BS EN 1869:2019, the European standard for fire blankets, and many are also UL-certified in the United States. These certifications ensure performance under extreme heat and usability in real-life emergencies. As a result, fire blankets are widely trusted by homeowners, commercial kitchen operators, school districts, and RV owners for their fire safety needs.
Should You Have One?
Absolutely. A fire blanket is a low-cost, highly effective addition to your fire safety plan. Whether you’re frying food at home, managing tools in a workshop, or storing batteries in your garage, it offers fast, simple, non-toxic fire control that anyone can use — no training or mess required.
That’s why safety experts recommend keeping a fire blanket in every kitchen, vehicle, and workspace. If your home doesn’t have one yet, now is the time to add this essential tool to your fire safety kit.

Fire Blankets vs. Fire Extinguishers
Fire blankets and fire extinguishers serve distinct purposes. Fire blankets are effective for small, contained fires such as kitchen grease fires and clothing fires by smothering flames and cutting off the oxygen supply. In contrast, fire extinguishers, using chemical agents or CO₂, are necessary for larger or spreading fires, including electrical fires and flammable liquid fires, which can exceed 800°C (1,472°F).
For Class A, B, and K fires, fire blankets provide a residue-free, quick solution, making them ideal for homes, kitchens, and labs. Fire extinguishers (ABC, CO₂, dry chemical types) are essential for fuel-based and industrial fires. However, for EV fires, traditional extinguishers are ineffective due to thermal runaway. In these cases, only a specialized EV fire blanket can effectively contain flames, prevent gas spread, and isolate the fire until emergency responders arrive.
NFPA 10 and OSHA fire codes mandate properly maintained fire extinguishers in workplaces, while NFPA 701-certified fire blankets provide additional protection in areas with open flames or flammable materials. Fire blankets meeting NFPA 701, FM 4950, and ASTM E84 standards help protect against sparks, molten metal, and high heat. For EV fires, high-temperature graphite-coated blankets are essential for containing fires above 1,100°C (2,012°F) and preventing toxic fume release.
Having both fire blankets and fire extinguishers ensures comprehensive fire safety, covering various fire hazards, including EV-related incidents.
How Does A Fire Blanket Work?
Fire blankets work by physically covering the fire source to cut off the oxygen supply, interrupting the combustion process. Their effectiveness is determined by the materials and coatings used, making them suitable for various fire scenarios. Below is a fully integrated summary of how different types of fire blankets operate.
Fire blankets made from fiberglass function by tightly adhering to the fire source to form a barrier that isolates oxygen while absorbing heat. Their flexibility allows them to adapt to irregular surfaces, making them ideal for putting out small fires, such as kitchen grease fires, withstanding temperatures up to 550°C (1,022°F). Enhanced with silicone coatings, they gain resistance to liquid flames and chemical corrosion, making them effective for grease and chemical fires. Silicone-coated blankets block liquid flames from penetrating the material while maintaining stability in temperatures from 260°C to 550°C (500°F–1,022°F).
For higher-temperature scenarios, high-silica fire blankets excel in insulating and stabilizing fires involving industrial equipment or pipelines. Their low thermal conductivity reduces surrounding heat while maintaining integrity at up to 1,000°C (1,832°F). Adding a vermiculite coating makes these blankets resistant to molten debris and high-temperature sparks, ensuring protection in environments such as welding and cutting operations, where they withstand sparks as hot as 1,200°C (2,192°F).
In extreme fire situations, such as lithium battery or aviation engine fires, graphite-coated high-silica blankets combine high heat resistance and thermal conductivity to dissipate heat and prevent re-ignition. These blankets are designed to endure temperatures as high as 1,100°C (2,012°F) while maintaining physical integrity in high-pressure, dynamic environments.
Fire blankets, whether made from fiberglass, high-silica, or coated with silicone, vermiculite, or graphite, provide a versatile and efficient fire safety solution. Their ability to smother flames, resist liquid penetration, block sparks, and isolate high temperatures makes them indispensable for controlling and extinguishing fires across household, industrial, and extreme environments.
