A house in my street almost burnt to the ground this week. We had three fire engines here for hours.
This evening the fire brigade visited us all, checked our smoke alarms or had free ones to fit.
They offered each house advice too. The best advice (which won’t work for all) is to close all internal doors at night especially downstairs and bedroom door. Most fires start in the kitchen so if you shut all downstairs doors it buys you more time to hear the alarm and get out of the house if you are sleep.
I know this post is the most boring ever but please do check your alarms.
