Locks with thumbturn or lock?

[cledry]

How about key cylinder outside and nothing inside?
Dummy cylinder or whatever.

That is most certainly against code. I had a bank request this about 2 months ago. i declined. Too easy to lock someone inside.

Same thing as with a double cylinder if no one inside has a key.

ways i've seen single side cores allowed:

- secure facilities where access is heavily controlled and egress isn't an issue(jails, prisons, mental institutions) (or is overridden such that AHJ can't argue, like national security)
- where interior panic hardware overrides it (panic bar or active lever on inside will retract bolt)
- "extra" doors that are not "egress" (just did this on a small event center - the main doors in the hall with exit signs over them had interior active levers(see above) and keyed deadlatches )- all of the extra french doors to the patio had key one side bolts to secure them and dummy levers)
- inaccessible spaces - somewhere like a "mechanical closet" that's really a door in front of the air handler that you open to change the filter, but you can't bodily fit in the "room" with the unit.

and yesterday afternoon (talk about timely to discussion) we had an code reviewer *mandate* keyed interior locks on a storefront where client had requested thumbturn.

working on projects all over the country (haven't done any project overseas recently) local variations in code are impressive. i've got active or just finished projects in based on based on model codes from between 2009 and 2015, and that's not including state or local edits to those model codes. what's allowable in one building may not be a mile down the road.

Just another sort of related thought: Construction installed mortise locks here (without asking me, of course) that had deadbolts in them. These were put in on doors leading to the roof, which need to be be locked on the INSIDE but free on the outside. I was going to order Corbin Russwin thumbturn cylinders but couldn't find the right ones, so I called the tech guy. He told me they got sued because of a case where the cam jammed the bolt so a person couldn't egress, so they stopped making thumbturn cylinders with standard cams.

they stopped making thumbturns???

i've gotta ask though, why deadbolts? keyed lever on inside is functionally as secure if you've got panic open on exterior, and 1 less piece of hardware.

I'm no lawyer.... obviously
After looking at a comparison of 2010ADA & 2012IBC,

But, I would have to say that since neither my house,
nor any of the structures I work within, will ever leave the borders of the U.S.A. ...

I'm not concerned with either nato or interpol, enforcing any codes, ei... grass height, accessibility, wiring, work safety, etc...

Point trying to put out, before I get anyone's panties get bunched up... anything that has "International" in the title, is just that, a "title" & has no enforceable effects, unless an American law was signed to place the same stipulations. Any foreign laws of general codes for code of living, are just that... foreign, & only accepted as a matrix to try to meet & exceed way of life as to be,
" Keeping up with the Jones's. "

Ever noticed both FBI & INTERPOL warnings,
Waiting to watch a movie at home.
(movies mass produced by foreign companies)

American legal system was set up with checks & balances so that everything is not cookie cutter made for lack of progress & leaving society to crumble & rot.

Unfortunately, seems society is letting their rep.s get away with letting this ideal die. Because if it'snot all about me, then f-it...

That is why so many people put themselves in harms way & died for.

Now that I've helped get this derailed train further off track, let's look at it this way...
I'd imagine terrorist would be more likely to use
chain-padlock, (real /toy steel) handcuffs, bike lock, etc... due to people would be able to unlock thumb turn or realize that this is SHTF,when / if someone locks & takes something big enough to break off the latch, & does.

This is my opinion on it.

ps... example of such a check & balance;
as a member of municipality (local government),
do not fall under OSHA, but local branch can hold us accountable to same penalties for the same type of offense.

torch,

the ICC code suite is the standard building code adopted by state and local jurisdictions across the usa. it's developed by (mostly) usa engineers, architects and other related professionals, and the organization is based in washington dc. many state and local officials have decided that rather than take the time to reinvent the wheel, they're going to take what are generally accepted as best practices, and use those (or at least start with them). the "international" is in no small part because jurisdictions in other nations are following our lead.

most jurisdictions in the usa, including kansas city, have adopted IBC, which means that those codes ARE laws, and they're not "foreign" unless you consider DC to be part of russia, or your city officials to be not lawfully elected foreign agents. your local officials have said that it's the law for you.

no offense, just frank honesty: your opinion on this is based on a woefully ignorant pile of misinformation

Just swap the body for a different function, storeroom. Then the cylinder goes on the inside, you can put a dummy in the exterior. No big deal.

That's exactly what I have to do, but I want the construction company to pick up the tab...for six of them.

Thumbturns with standard or cloverleaf cams, I should have said.
