Closing doors on a fire alarm seems hilariously cruel.
- c22 3y agoIt prevents the fire from quickly moving through the building...

- zamadatix 3y agoYeah, that's a given, but the point of fire doors is to maximize overall survivability instead of the "average doors crossed per minute" stat in isolation.
- withinboredom 3y agoThe doors don't lock, they just close.
- flyinghamster 3y agoIn many large buildings (schools, etc. in particular), you want the internal fire doors to close to keep the fire from spreading. Of course, exits must be provided for each isolated section.
- chedabob 3y agoThese are installed on doors that have an auto-closer anyway. They deter people from propping them open permanently with a wedge or a chair.
