Why are my smoke detectors going off when I cook?
The obvious (but ultimately unhelpful) answer is that the heat/smoke from your cooking is setting off the alarm. So what you have to do is reduce the heat/smoke getting to the alarm.

There are a number of things you can do:


If you don't have a smoke alarm in the kitchen close the door while cooking. This will stop the fumes reaching the detector.
Use the cooker hood's extractor fan to help divert the fumes. If it doesn't have one, consider fitting one.
If you have a smoke alarm in the kitchen make sure it's of a suitable type. The standard ones are (quite rightly) designed to be sensitive to any smoke/heat. A kitchen one will be less sensitive to heat (for example).
Clean your cooker. This might reduce the particles being emitted. You might not be able to see them, but they are there.
