Cooking Indoors Safely When the Power Is Out

A hot meal changes the mood of a blackout more than any other single thing. It is also where people take the worst risks — every winter, someone brings a charcoal grill or a camping stove indoors and does not wake up. Here is what is genuinely safe inside four walls, and how to get the most out of it.

Why this is the dangerous chapter

Carbon monoxide is odourless, and the appliances that produce most of it — charcoal, petrol generators, unvented paraffin heaters — feel perfectly normal right up to the point where you cannot stand up. Getting this right is not caution; it is the whole skill.

What you need

• A canister gas stove with an adjustable, clean blue flame
• A pot with a tight lid — a lid cuts fuel use by roughly a third
• A carbon monoxide alarm, battery powered, in the room where you cook
• Simple food that needs heat, not cooking time: soups, pasta, instant rice, tinned stews

Cook without the grid

1. 01

   Never burn charcoal or petrol indoors. Ever. Not in a fireplace, not on a balcony next to an open window, not "just for a minute".

2. 02

   Use a gas stove on a hard, stable surface with a window cracked open for ventilation and a CO alarm in the room.

3. 03

   Boil once, use twice. Heat a full pot, use what you need, pour the rest into a flask. Reheating is fuel you do not have.

4. 04

   Insulate the pot. Bring rice or pasta to the boil for two minutes, then wrap the covered pot in a towel and a jumper for 20 minutes. It finishes cooking on stored heat.

5. 05

   Eat from the fridge first, freezer second, cupboard last. Cook the perishables while they are still good.

6. 06

   One pot, one wash. Water for washing up is water you cannot drink. Line bowls with foil or eat straight from the pot.

The mistakes that cost people a safe night

• Any solid-fuel or petrol appliance used indoors
• Cooking in an unventilated bathroom or hallway
• Leaving a stove unattended on an uneven surface
• Buying a stove without ever testing it before the emergency

Common questions

Is a fondue or alcohol burner safe indoors? With ventilation and supervision, small alcohol burners are workable, but they are slow and easy to knock over. Gas is safer and faster.

Can I use a barbecue on the balcony? Gas, with the door mostly closed and the balcony genuinely open, is defensible. Charcoal never is — CO drifts back inside.

Where kit is worth the money

A small gas stove, two spare canisters and a CO alarm cost less than a takeaway weekend and cover every outage you are likely to see for the next decade. The alarm in particular is not an accessory — it is the item that makes the rest of this safe.
