Turnstiles

[JBI]

Each turnstyle has a maximum capacity of 50 persons. No matter how many turnstyles you put in, they can never be counted for more than 50% of total required egress, the other 50% must egress through other-than-turnstyle exits.

Like a delayed egress emergency exit that restricts egress at normal conditions but allows instant use in an emergency.

put what if those three turnstiles are lined up next to each other, in front of a 3/0 door??

I think a floor plan is needed, to answer a set scenario

I'm not in a position to provide a floor plan, but suffice it to say that based on JBI's comment, that answers my question. Additional egress will need to be provided as of right now, all the egress must go through the turnstiles.

sorry been going round in circles with this one

yes your original set up where every door had a turnstile does not meet code

do not understand why they want to use turnstiles, when there are other means to account for thier people coming and going, and also since it will cost more money

Thanks cda. The company wants to use them to control security; not sure why the extreme measures here with the restrictive turnstiles. I've shared my concerns with the architect on the project after you all have confirmed my suspicions.

have seen different configurations of below, so you still have the turnstiles, but also have a means to bypass the turnstiles, and see that would be legal:::

unless they have it working at another facility, I think once they put in in practice they will see it is more of a problem than a help

I think the occupant load of fifty will get them. If you are limited to a specific amount of people by the code and you cannot get the occupant load out.. even though they have the correct amount of exits then additional exits would be required.

No matter what the code stupidly allows at the behest of the turnstyle lobby this designer would not place them in ANY egress path.

If security is the issue I would provide exits to an adequatly remote properly sized exterior courtyard and then let security decide who

can leave the premesis. placing obstacles in the way of egress has been proven a bad thing.

As a CBO you would be allowed the minimum level of stupidity

A bit harsh Arch1281, don't you think? Glad to hear you wouldn't put them in MOE BTW.
