Had an interesting morning yesterday, got out of work at 4AM and stayed up to meet my GF for a quick breakfast in Niagara Falls Canada, got home at around 8AM. I was pretty tired from the long shift and the driving to and from the border so I was upstairs in bed pretty quickly like maybe 5 minutes after getting home. Thankfully instead of passing out straight away I derped around on my phone for about 10 minutes and then I heard it...smoke alarm downstairs. Run downstairs straight up naked and my entire kitchen is filling with thick smoke ! Somehow the toaster oven was turned on. I haven't used that thing in months I have zero clue as to how the heck it was on (the dial showed it was off). Grabbed some pot holders and ran that thing outside to my patio (still naked) and opened up every window in my house to dissipate the smoke. I am the worst at checking my detector batteries I know for a fact I have a couple that aren't working that is going to change very very soon. Also definitely picking up a fire extinguisher. Man that got my blood flowing. Also I'm a pretty heavy sleeper and I was exhausted, I don't think the alarm downstairs would ever wake me up it'd have to hit the detector right above my bed. Scary thought.
TLDR: toaster oven went rogue and tried to light my house on fire minutes before I was supposed to be sleeping smoke alarm saved my life.
I'm nuts with fire safety. Know a couple people personally who had house fires, I'm not taking any chances. Every single room has a fire alarm. Might be overkill, but I'd rather spend a few extra bucks & err on the side of caution than die in my sleep. My setup right now is a slim 2-story rental with a walk-out basement:
1. Nest alarm on each floor (main room: basement, dining room, upstairs hallway). Wi-fi app alerts you to alarms.
2. Kidde alarms in each bedroom. Talks to my Wink Hub, which relays Wi-fi app alerts for alarms. Half the price of the Nests, so easier to buy more of them...plus a separate system, just in case of any service problems.
3. Fire ladders at each window above first ground level.
4. Fire extinguishers on each floor.
Bonus, the smart alarms remind you when the battery is low, so you don't have to listen to constant chirping. The one thing I wish I had, which is available on newer construction, is a residential cold-water sprinkler system that is fire-activated. Yeah, it cost a few hundred bucks to buy everything (well, I bought it incrementally over time, so it wasn't that bad), but it gives you good piece of mind. Also threw all of my important documents in a small portable fireproof safe (birth certificate, social security card, etc.) & have a 72-hour kit for each family member. I've had to bug out before (in Florida, from hurricane flooding; in Connecticut, from an extended power loss in the dead of winter that made it too cold to stay in the house) & it just makes life more convenient. Update the bags once every corner & swap out the alarm batteries a couple times a year.
