I’ve posted about this in the past (here’s another one), but I still don’t know of a code requirement that specifically prohibits or permits the application shown in today’s Fixed-it Friday photo from Mark Buckley of Allegion. The plastic chain would likely be easy to break, but how much of a deterrent is too much? It’s kind of like the question of signage deterring use of an egress door, those little stickers or tags that show if the door gets opened, or the velvet ropes.
Should these methods be addressed in the model codes? Thoughts?

I can’t tell if that is plastic chain?
Anyway my five cents:
1. ADA requirements?
2. That pesky International Fire Code
IFC 2024
1032.3 Obstructions
A means of egress shall be free from obstructions that would prevent its use, including the accumulation of snow and
1032.2.1 Security Devices and Egress Locks
Security devices affecting means of egress shall be subject to approval of the fire code official. Security devices and locking arrangements in the means of egress that restrict, control, or delay egress shall be installed and maintained as required by this chapter
1032.2 Reliability
Required exit accesses, exits and exit discharges shall be continuously maintained free from obstructions or impediments to full instant use in the case of fire or other emergency where the building area served by the means of egress is occupied. An exit or exit passageway shall not be used for any purpose that interferes with a means of egress.
Delayed egress would provide better deterrence than this and also provide better safety by unlocking upon fire alarm activation and not requiring tight pinching to remove the chain. Is this an occupancy that does not allow delayed egress? A 3-second delayed egress lock would probably be much better than this.
It is a retail occupancy so delayed egress would be allowed, but it’s obviously a lot more expensive than a plastic chain. I’m guessing that was the deciding factor.

Hi,
As an AHJ. I would not allow .If a senior citizen or somebody with limited strength,( which I am both) I may not be able to break the chain. Also in smoky condition I have to reach for two ways to open door. P.S Didn’t see an Illuminated exit sign.
Thanks Tom!

1008.1.9.5 Unlatching. (the intent of the code) only allows one operation. Pushing on the panic hardware is one operation. Breaking the chain, though easily done, is two operations. I would not permit it.
