Fire blanket or fire extinguisher

Updated: October 2026

A pan of oil is alight and both a pouch and an extinguisher are within reach. The question is fire blanket or fire extinguisher, and the honest UK answer is often neither: leave and call 999. Where a fire service still names a household tool for that pan, it names a blanket, not a jet. Hampshire says never use a fire extinguisher on cooking oil or a chip pan, because it can spread the flames. The [fire blanket comparison](/hub/fire-protection/fire-blanket) lists the pouches. This page is the tool choice. If you are unsure, or the fire has left the rim, close the door if you can and call 999.

Why a jet is the wrong tool on a pan of oil

Hot oil is a liquid. A jet hits it and throws burning fat out of the pan. Hampshire, West Sussex, Bedfordshire, and Devon and Somerset warn that an extinguisher can force burning fat out of a chip pan. Water does the same thing as a fireball. London Fire Brigade and GOV.UK agree on never using water. Foam that is water-based, dry powder, and CO2 are still a discharge into burning fat unless the extinguisher is the low-pressure wet-chemical type, and even then Hampshire’s chip-pan warning does not disappear. The Caravan Club notes that AFFF is water-based and not for a chip pan.

When a blanket is the tool they still name

Hampshire says cover a small pan with a fire blanket if that is safe. West Sussex says do not use an extinguisher on a pan of oil. Kidde UK says the spray can spread hot oil. You still have to cover it without leaning over it. The pull and the wait until cold are on how to use a fire blanket. London and GOV.UK do not offer this step. The pouch does not overrule them. No blanket here has been fire-tested for this article.

What a class F extinguisher is for

Class F, in the Fire Protection Association’s account, is cooking oils and fats. The extinguisher with an F rating is wet chemical, a low-pressure foam for deep-fat fryers, with training assumed. Hampshire lists wet chemical for cooking oils and still says never use a fire extinguisher on a chip pan. Wet chemical is not a fire blanket. Yikuneng and ougist mention Class F on their bullets. That is a listing claim. It does not give you an F number or a discharge time.

Leave, and the electrical exception

Leave, close the door, and call 999 when the fire has left the pan, when you cannot cover it without leaning over it, or when you are unsure. An electrical fire is a different case. Cornwall and West Sussex allow a blanket, or a dry-powder or CO2 extinguisher, only after the power is off, and they say never use water. Size and edition are on the fire blanket buying guide.

Blanket, jet, or the exit

If the fire is still a small pan you can cover without leaning over it, the services that still name a tool name a fire blanket. Hampshire refuses the extinguisher on a chip pan. If you are unsure, leave and call 999. Powder versus foam in a van is on the fire blanket for a caravan page. A qualifying purchase can earn a commission at no extra cost to you.

Common questions

Should you use a fire blanket or a fire extinguisher on a chip pan?
If the fire is still a small pan you can cover without leaning over it, the services that still name a tool name a fire blanket, not an extinguisher. Hampshire, West Sussex, and Kidde UK say the jet can spread burning oil. If you are unsure, leave and call 999. London does not offer either tool for that pan.
Is a wet-chemical extinguisher the same as a fire blanket?
No. Wet chemical is an extinguisher with an F rating, described by the Fire Protection Association as a low-pressure foam for deep-fat fryers, with training assumed. A fire blanket is a sheet you lay over a small fire. Hampshire lists wet chemical for cooking oils and still says never use a fire extinguisher on a chip pan. Do not treat a yellow label as permission to spray a domestic pan.
What about foam, water, dry powder, or CO2 on a pan of oil?
Leave them off the pan. Water can make a fireball. Foam of the AFFF type is water-based. Dry powder and CO2 are still jets into hot oil unless you are in the separate electrical case, with the power off, and even then they are not the oil recommendation. The household warning from Hampshire is not to use a fire extinguisher on a chip pan.
What if the fire is in a toaster or a plug, not in oil?
Switch off at the plug or the consumer unit if you can do it safely, then Cornwall and West Sussex allow a blanket or a dry-powder or CO2 extinguisher, and never water. If you cannot isolate the power, leave and call 999. Do not use that electrical sequence on a pan of oil, and do not use the oil sequence on a live appliance.
Do the blankets in this set count as a class F extinguisher?
No. They are sheets in pouches or a hard case. A bullet that says Class F, on the Yikuneng or ougist listings, is the seller’s claim, not an F rating and not a fire test. There is no discharge time and no wet-chemical agent. A class F extinguisher is a different product, aimed at fryers, and it is not a reason to spray a chip pan at home.
