Overview
A 40 by 40 inch fiberglass fire blanket sold in a 4 pack, meant to smother small kitchen, grease and biofuel fires by cutting off oxygen rather than spraying a chemical agent. Each blanket packs into its own red pouch for wall or drawer storage.
Unlike a canister extinguisher, a fire blanket has no gauge to check and no propellant that can lose pressure over years, so it sits ready without a maintenance routine. The tradeoff is reach and duration: a blanket smothers only the fire it can physically cover and is not rated for a fire already sourced in wiring. The 4 pack spreads coverage across kitchen, garage, camp gear and a car without buying four separate units.
- 40 x 40 inch fiberglass blanket, 4 pack
- Smothers grease, liquid and biofuel fires
- No training or maintenance required
- Ships in a red storage pouch
Who it's for
Suits households wanting one item near the stove, one in the garage and one at the campsite without tracking recharge dates or inspection tags. Not the choice for anyone who wants a single tool rated for electrical panels or a fire beyond arm's reach.
Pros and cons
- No expiration date or pressure gauge to monitor
- Doubles as a fire wrap for a person, not just an object
- Compact pouch mounts near a stove or grill
- Four included, enough for kitchen, garage and car
- Not rated for electrical fires per the listing
- Only smothers what it fully covers, no spray reach
- Single use once deployed, no refill
Performance notes
The fiberglass fabric works by starving a fire of oxygen, either wrapped around a person whose clothing has caught or draped directly over a pan or grill flame. Because it has no chemical charge, it does not expire the way a pressurized extinguisher does and needs no yearly check, though its effectiveness still depends on fully covering the flame on the first attempt.

Frequently asked questions
Is the Wuerli fire blanket rated for electrical fires?
No. The listing states it should not be used on electrical fires; it is intended for liquid, grease and biofuel flames.
How many blankets come in the pack?
Four, each in its own storage pouch, sized 40 by 40 inches.
Does a fire blanket expire like a fire extinguisher?
No. It has no pressurized charge, so it does not carry the shelf life or gauge check that a canister extinguisher needs.
