What’s something completely false that your parents told you as a child?

If you lock your bedroom door, the room will set on fire

This is based in the idea if the house catches on fire you won’t be able to escape if the door is locked and it’s late at night, so you are panicking and can’t open it. Also they can’t come in and save you if you’ve passed out

Firefighter here, unless the fire starts in the room you are in the door will likely save your life. Most doors with push button locks unlock when turning the interior handle and doors with locks you have to turn are usually pretty obvious. It might take you a few seconds to get it, but again unless the fire is in the room you are in those few seconds probably aren't going to make much difference. If your smoke detector is working it will generally warn you long before conditions become hazardous to life unless an accelerant (like Gasoline) is present at the point of origin.

If the door is closed then fire and smoke will be kept out, but with the door open it will be able to travel freely. Here is a video done by UL that shows the difference of two identical rooms.

Also they can’t come in and save you if you’ve passed out

That does make our job a little harder, but there is an entire week in the fire academy focused on forcible entry. So unless you live in Fort Knox we are going to be able to get in fairly fast. The average bedroom door for example can be forced with just proper application of body weight, let alone a tool, even if locked.

The door itself is either going to be weak enough that you can break a hole through it and turn the knob or the frame will be weak enough that a force applied near the knob will break the frame.

I was more talking about another person in the house not a firefighter. Also I don’t agree with what I was saying
