Preparing for outages

I used my calor one indoors when we were having the kitchen changed. I used it in a room where we had a gas fire on the principle that if it was well-ventilated enough for a gas fire it would be OK for a gas stove.

The general advice for appliances that use camping gas or propane is to use them outdoors where possible, or in a large well-ventilated area under cover. That's probably because such gases are in liquid form, so if the stove/heater/lamp gets knocked over, there's a change of spillage and a resulting fire.
That's not to say they're terribly dangerous, as long as you use them safely.

I wouldn’t use a camping stove indoors myself but each to his own
I m not doing any of this stuff I really can’t spend my life worrying about ‘maybes’ I ve always got tinned food in the cupboard and if I lose my electric I ve got gas if I lose both I ll eat everything cold, no big problem, I heat with a gas fire and my water is gas
I have a torch and I have a Power bank and that’s as far as I m going

They use camping gas, either propane or butane or a mixture of both (ready-mixed - it is not advisable to mix-it-yourself).

Propane works better in below-freezing conditions, so is used in the big gas cylinders and takes that you se in rural districts where household cannot get connected to town gas. Propane requires thicker, higher-pressure steel tanks and must be stored outdoors.
Choose Butane if: You are indoors, using a portable stove in warm weather (above 10°C / 50°F), or prioritising a lightweight, compact canister.

You should always have plenty of ventilation, whichever you use. Follow the instructions on it.

There are many small camping stoves on sale on the internet. What you get depends on how much you will be cooking on it at a time, from little folding stoves which hold one saucepan or a kettle up to two-burner ones that hold two pans, or even one meant for a rural kitchen with several burners and a grill and/or oven.

I will look up the size and price of mine (at the smaller end of the market) and post again later.

Not a helpful reply as you have a gas cooker BlueBelle, so won’t be affected in the same way? Franbern you can get one or two station, low to the worktop camping gas rings that connect to the small gas bottle with a pipe rather than perching on top of it, so are safer to use. I got mine in Aldi, but they sell them in Argos, or camping shops. I kept an old kettle from when we had a caravan, but you might want to think about a kettle rather than a saucepan too. This is an example.

There's a type of single burner gas cooker where the gas cylinder fits in a compartment beside it, so no trailing hose and it's low, so little danger of knocking over. I'll try and find a picture- but widely available.

And this is my folding one burner stove, which does indeed fold into a very small box (provided you took careful note of how it was folded when you took it out of the box. It takes up very little space when in its box, but it holds my ordinary kitchen saucepans, even a big one and it is very stable, though it looks sketchy. Box is 4 ins x 4 ins x 2.5 ins

Beware carbon monoxide poisoning if you use a camping stove indoors, I thought that that wasn’t advisable. Perhaps with good ventilation but I wouldn’t. If I get one, I’ll use it just inside my open garage.

It’s okay for as long as it takes to boil a kettle, as long as you open the window so there is no gas build up. When our electricity has been off, I’ve boiled the kettle full in the morning, and put the surplus water in a flask to use later.

EkwaNimitee is correct re carbon dioxide.

None of the aforementioned stoves are recommended for indoor use

That’s the spirit.
Mr P goes away 4 times a year for is hobby/ pastime.
I don’t / havnt cooked for many years.
Although there is a full size freezer stocked to the brim I survive on sandwiches, crackers, cheese, coleslaw, cold cut meats.
But he always makes me a bread pudding and a feta, basil filo pastry pie and boiled eggs.

No, but in extremis, I take the precautions in the knowledge that the risk of carbon monoxide poisoning must be mitigated by keeping the window open. It’s either that or don’t have anything hot or have a hot water bottle, when central heating also won’t be working. Personal choice and all that.

I think knowledge of the potential risks should help mitigate disasters. That's all.
