I worked in community safety for a Fire and Rescue Service for nearly 30 years, it was my job to educate the community in home fire safety.
Ot is of course important to have a fire plan that everyone is aware of, to involve children by discussing this, and to practice it.
More important is fire prevention - so ensure you have a bedtime routine. Eg. candles are extinguished, putting water in ashtrays before emptying, turning off appliances except those with timers/fridges and freezers, closing all internal doors.
All internal doors have to be fire resistant for at least 30 mins. In most areas the Fire Service should reach you in less than 6 mins.
You should have smoke detectors in any room where a fire could start and a heat detector in the kitchen. Preferably these should be linked if possible.
You should be able to evacuate the home and call the fire brigade from outside, closing each door you go through to prevent fire spread. If there is smoke, stay low, and ‘bump’ down the stairs to prevent falls.
If you are unable to evacuate, get everyone into one room, block the gap under the door with a pillow or towel, open the window for ventilation and shout FIRE!
Do not try to escape by through the window unless the room is smokelogged and you can feel heat through the door, (Many people sustain injuries falling from height). Fire Crews will assist you out by ladder if necessary. Tell children never to hide in their rooms, but to stay by the window.
Follow instructions from the Control Officer who will stay on the phone with you.
Have a look at the website for your local Fire and Rescue Service. Many have online home fire safety checkers which will alert you to any fire risks. They will also provide free home fire safety visits to vulnerable households.
