Firefighter here;
Sleep with your doors shut at night (helps prevent fire spread/smoke inhalation)
Be able to crawl, blindfolded, out of every room in your house.
Make sure everyone in your home knows what to do in the event of a fire. Where to meet afterwards, etc.
If you have kids, explain to them that firefighters may look ‘scary’ in full turnout gear, but they can not be afraid of us.
Friendly reminder while I have your attention; check the batteries in your smoke detector. They truly are life savers.
