One of my coworkers is working with a school that has an incoming student with special needs who has a history of "running" - leaving the building during the school day. The school is very concerned about the safety of this child, but since the code requires free egress there are really no options without requesting a variance. I don't know how many teachers will typically be in the classroom, but that's obviously not within our control and since this has been a problem in the past, the level of staffing may not be sufficient.
I'm picturing the exit door from the classroom to the exterior. One solution could be an electromagnetic lock which unlocks on fire alarm and with a remote release that is under the control of the teacher.
Another possibility is a delayed egress system which unlocks 15 seconds after you push on it and unlocks immediately on fire alarm. The code requires an audible alarm, which would not work in this situation. I would propose a delayed egress lock without the audible alarm. Delayed egress is not allowed by the IBC in schools so it would require a variance regardless.
What are your thoughts on this? If one of these solutions would be acceptable to you, would you limit your approval to certain doors (ie. ok in the classroom but not on the gym)? What could be incorporated into the plan (ie. staff training) that would make the variance more acceptable to the AHJ?
