A malfunctioning power strip is getting most of the media attention for causing this fire, but Fox 13 reported that “a closed door kept the fire from spreading beyond the guidance counselors’ offices, and therefore it did not reach any classrooms.” The fire reportedly caused at least $100,000 in damage even though it was contained to 2 offices and was put out by the fire department within a half hour. Imagine the damage and disruption that would have been likely if the door was open. Fire doors and even non-rated doors are important tools in fire prevention – I’m so glad fire departments are starting to recognize this.
I’ve heard of several jurisdictions recently that are enforcing the fire door inspection requirements of NFPA 80…if you’ve seen any progress on this in your area, let me know!
Today’s Wordless Wednesday photo came from RB Sontag of Allegion. This is a roof door (which really shouldn’t be an emergency exit anyway) and I can’t imagine how secure a chain wrapped around the lever would be, but if the exit is to be taken out of service they should talk to the fire marshal and change the signage…
These are not the same doors – these have a top rail instead of an HDB bracket.
I know that some of you will be able to help with this question from a contractor, who has all-glass doors with direct-hold magnets making noise when the doors close and when the mag-locks engage. Originally, I thought he might have shear locks, which are notoriously noisy, but they are surface-mounted mag-locks, not shear locks. The all-glass doors in question have brackets that slip over the top of the glass for the armature to attach to (HDB brackets) – I’m not sure if this affects the sound at all.
I’m thinking the closing speed/force on the closers could be adjusted to help close the doors more slowly and with less force to minimize the noise of the armature closing against the magnet, but if the engagement of the lock also makes an objectionable noise, what can be done?
If you have any ideas, leave a comment below, and thanks in advance for your help!
