We had a false alarm go off in the building where I work last week. The elevators automatically shut down forcing the use of the fire escapes. The building is 22 floors. I was lucky in that I’d just taken the elevator to the first floor to step outside on a break. When they finally let us back in, I wondered what someone with mobility issues is expected to do had the building been on fire. Just die? Have a kind soul carry them? With most people wfh at least a couple of days per week, this seems really dangerous for anyone who might get stranded.
At my office each stairwell has a riding chair at the top. It’s only three stories though.
…architect here: we design protected areas of refuge where mobilty-impared occupants can shelter in place until emergency services arrive to evacuate them from the facility…
…you’ll often see areas of refuge identified near elevator lobbies and equipped with hardened callboxes for emergency communication, or marked on the evacuation plan if they’re in a remote location…sometimes areas of refuge are pretty subtle if you don’t know to look for them: we design protected firewalls, structure, and building systems integrated into the facility so the biggest tells are usually callboxes, magnetic door hold-opens, or tracks for automatic fire curtains…
…when renovating older facilities, we do the best we can to modernise life safety within the limitations of existing infrastructure, but the general rule of thumb is that as long as you’ve improved upon what originally previously existed, you’ve satisfied your obligation even if it’s not at parity with new construction…
(it’s not uncommon for old facilities to have gone through a dozen or more life-safety modernisations since the advent of modern building codes, just palimpsested one-over-the-other as standards progressed)
Thanks so much for the info. I’m curious if you know about when these practices became common. The building I’m in for work, for example, has carpet in the hallways that looks like it was installed in the late 90s-2000s. The style of the outside seems to fit this range. Would you expect to see some, most, or all of these techniques in a building from that era? (This is in Cali, so likely early to apply the regulations I would think.)
…that’d take a deep dive into obsolete building codes to identify exactly when the concept was first introduced: BOCA, southern/standard, and uniform building codes all merged into IBC about twenty-five years ago so we’re talking about old paper code books from twentieth century…
…areas of refuge are closely tied to modern accessibility standards which arose from the ADA in 1990; i’m guessing they were widely introduced sometime in that decade, possibly earlier for high-rises or hazardous occupancies, but they were definitely part of 1997 UBC (which most of california enforced) and 2000 IBC…
(i started working professionally in 1993 and every project i worked on was fully accessible, but adoption varied across different jurisdictions and when i worked in california a decade later they were waaaay less accessible than texas)
In my workplace, there are a few options: When a disabled person is on a certain floor above ground floor, there will be a special chair they can be put in, that allows one person to maneuver them down the fire escape. Multiple people in the company are trained on the use of this contraption and are notified before the evacuation is necessary.
When there are more wheelchair bound people in the building than there are evacuation chairs available, they’ll have to be taken to the fire escape behind double fireproof doors, where the area is pressurized with clean air. There the firemen will evacuate them.
A third option is the area where the elevators are. It closes automatically and has a fireproof door where you can wait in front of the elevators for the firemen to evacuate you using the elevators (or otherwise).
Normally there aren’t that many wheelchair bound people in the building that need those chairs, because visitors are normally confined to the ground floor. On a floor where a disabled person used to work (now retired), one of those chairs was permanently available.
Edit: the ones we have resemble these https://evac-chair.com/
These things are absolutely terrifying btw. There’s much better options out there. I never realized until I had the chance to ride one during a practice, I replaced every single one of them for our company after that for evacuation mattresses.
We have a different brand, but otherwise comparable. During our training and practice, we did a few runs with volunteers and also with the colleague who was wheelchair bound. While it does feel a bit weird the first time, it doesn’t feel unsafe to sit in, and also when operating it, you feel like in control without too much effort.
During our evacuations, everybody remains calm, and everything remains orderly and coordinated. I have to admit we never had an evacuation with fire and smoke near the people, but with the early warnings we get, that’s unlikely to happen. The building was designed with good compartmentalisation, so even when there’s a fire, the smoke shouldn’t spread too far.
Good on you, that thing looks terrifying to sit in. I guess a fire is pretty good motivation to strap into the damn thing but it doesn’t look safe at all. I was expecting like sled tracks with a triple wheeled axle that would have some kind of hand break to keep it from free sledding down the stairs and stop entirely if released.
It’s kinda hard to explain, but you need to kinda push it down the stairs. The tracks have loads of resistance, providing it’s maintained properly. I don’t think it’s unsafe with proper maintenance, but the experience of sitting in that chair surely makes you question if you’re absolutely sure about that. You can’t see the tracks from where you’re sitting, and your legs just dangle above a height you perceive as 2+ meters because of the slope of the stairs and the incline of the chair. And then the person behind you actively pushes you into that, making you instinctively react to an incoming free fall.
Also in a fire or any other evacuation it’s very important you stay calm. You’re not gonna stay calm in this. I’m not scared easily but even I fucking hated it. Let alone someone thats wounded and scared to begin with.
I don’t know how many facility managers are here, but get an evac mattress. It’s cheaper and doesn’t need maintenance and is infinitely user Friendly.
One thing I haven’t seen in the thread yet, is that there ARE elevators which are intended for use during fire-related evacuations. I’ve been in buildings where signs by the elevators make it known that during evacuations you are SUPPOSED to use them.
I don’t know the specifics, but I would assume these have self-monitoring sensors to allow the elevator control system to determine whether it is affected by whatever is going on.
I suspect the way they work also changes, instead of prioritizing getting around different floors, the computer would start shuttling them up and down specifically to get people from each floor down to ground level. No-one already in the elevator gets to pick what floor they’re going to.
Modern buildings are constructed in a way that significantly slows the spread of a fire, and I would assume that the machinery and shaft of evacuation elevators, doubly so.
And same as any elevator, they are built using a level of redundancy that means several cables can fail without issue, as well as emergency brakes that arrest the fall of the cabin should the worst occur.
I’ve seen contraptions to carry people down stairs. These were meant to be carried by two able people.
Or two able people might just have to carry a disabled person down the stairs without a contraption.
I hope I’m remembering this right. Sounds humiliating but also problematic if people aren’t trained to do this and/or leave the building without knowing or caring.
