Quick answer

For a stove, a kitchen-size fire blanket such as the Prepared Hero Emergency Fire Blanket (39 x 39 in. open) hangs in a pouch by the cooktop and is pulled out by two tabs. For a grill or a larger area, Prepared Hero's XL blanket opens to about 4 by 6 feet. A blanket is a backup to the basics: USFA says to keep a pan lid or baking sheet nearby, turn the burner off, and leave and call 911 when a fire is not small and contained.

What a fire blanket does

A fire blanket is a sheet of fire-resistant fabric that you lay over a small fire to cover it. Prepared Hero describes its Emergency Fire Blanket as dual-layered fiberglass that, laid over a pan, covers the flames and cuts off the air the fire needs. It uses no chemicals, so there is no powder to clean up afterward.

The idea matches what the U.S. Fire Administration (USFA) tells home cooks: keep a pan lid or baking sheet nearby and use it to cover the pan if it catches fire. A fire blanket is a larger, ready-to-grab cover for the same kind of small fire. Prepared Hero also notes that water can make a grease fire spread, which is why a cover, not a cup of water, is the tool to reach for.

Kitchen size or XL size

Size the blanket to what it has to cover. Prepared Hero lists its standard blanket at 39 x 39 in. when fully open, folded to 8 x 12 in. in its wall pouch. That is the size to hang beside a cooktop, where the fire is most often a single pan.

Prepared Hero's XL blanket opens to about 4 by 6 feet, and the maker suggests it for covering a grill flare-up. The Amazon listing for the XL gives the size as 47 x 71 in. Pick the XL for a grill, a fire pit area or a garage bench, and keep the standard size by the stove, where a large sheet is harder to handle in a small space.

Where to hang it

A blanket only helps if you can reach it in seconds. Prepared Hero ships each blanket in its own wall pouch with a metal ring for hanging, and suggests hanging it beside the stove, in plain sight for everyone at home. Hang it on the side of the kitchen you would retreat toward, not behind the cooktop, so you never reach across flames to get it.

Show everyone in the house where it is and how the two pull tabs work. The same rule USFA gives for extinguishers applies here: make sure nothing is blocking or limiting your ability to reach it.

Blanket, spray or extinguisher

A blanket covers a fire; an extinguisher puts agent on it. USFA explains that home extinguishers carry class letters: Class A for ordinary combustibles, Class B for flammable liquids and Class C for energized electrical equipment, and that multipurpose A-B-C units cover most home fires. USFA also says to look for a UL Listed or ULC Listed label.

First Alert's KITCHEN5 is a kitchen extinguisher UL rated 5-B:C, sold with a mount, bracket and strap. Under USFA's labeling rule, the 5-B means it is rated for Class B fires up to 5 square feet. First Alert's AF400 EZ Fire Spray is an aerosol can that First Alert says extinguishes grease, paper, fabric, wood and electrical fires. Keeping a blanket and an extinguisher in the kitchen gives you a second option if the first is not enough.

When to use it, and when to leave

USFA gives a short checklist for deciding whether to fight a fire with an extinguisher. Have you alerted others? Has someone called the fire department? Are you physically able to do it? Is the fire small and contained to a single object or surface, like a pan or a wastebasket? Are you safe from the smoke, with a clear way out? USFA says to act only when every answer is yes.

Use the same test for a blanket. If you are unsure, USFA's advice is to alert others, leave the building and call 911 from a mobile or a neighbor's phone. USFA also says young children and older adults should not use fire extinguishers. A fire blanket is not a reason to stay in a room that is filling with smoke.

Prevent the pan fire in the first place

USFA's cooking advice is simple. Stand by your pan, and if you leave the kitchen, turn the burner off. Fires start when the heat is too high, so if you see smoke or the grease starts to boil, turn the burner off. Turn pot handles toward the back of the stove so no one can bump them or pull them over.

Keep the lid for the pan you are using within reach while you cook. It is the first cover USFA names, and it is already sized to the pan.

What to look for when you buy

Questions people ask

Do fire blankets work on grease fires?

Prepared Hero says its blanket is made for grease fires and, laid over a pan, cuts off the air the fire needs. USFA's own advice for a pan fire is to cover it with a lid or baking sheet and turn the burner off.

What size fire blanket do I need for a kitchen?

Prepared Hero's standard blanket opens to 39 x 39 in., sized for a pan on a cooktop. Its XL opens to about 4 by 6 feet for a grill.

Is a fire blanket better than a fire extinguisher?

They do different jobs. A blanket covers a small fire; an extinguisher sprays agent rated by class. USFA describes multipurpose A-B-C extinguishers for most home fires and says to look for a UL Listed label.

Can I put water on a grease fire?

No. Prepared Hero notes that water can make a grease fire spread. Turn the burner off and cover the pan, or leave and call 911.

Where should a fire blanket hang?

Prepared Hero suggests beside the stove, in plain sight. Keep it where you can reach it without reaching over the flames.
