[labnetwork] gas room means of egress

[Leif Johansen]

Hello Iulian, 

Here at DTU Danchip in Denmark we have a gas bunker which also located next to the cleanroom, but separated from this by quite a thick concrete wall. We have four rooms:

* One open yard with N2 tank, vaporiser, and O2 batteries.
* One closed room with N2 and O2 purifiers plus N2 and He gas bottles. Accessible through only one door from the street. 
* One closed room with corrosive gasses (Cl2, NH3 etc.). Accessible through only one door from the street.
* One closed room with flammable/pyrophoric gasses (H2, SiH4, B2H6, Cl2SiH2, etc.). Accessible through only one door from the street.

Hope this information could be of some help. I you wish, I could send you some pictures. 

Best regards, 

Leif

Dear Colleagues,

I am trying to influence a decision on a second means of egress from the gas room at the University of Delaware and your input is very much appreciated.

This is the room where the cabinets for toxic, flammable, and pyrophoric as well as some panels for inert gases will be located.  The room is adjacent to and separated from the cleanroom by a fire rated wall (I was told it is at least two hours-rated).  The code consultant states that a second means of egress is not needed for this H2 occupancy room but I feel it is a must.

How many doors does your gas room have?

Thank you very much.

Iulian
