Subject: [DCHAS-L] Length of aisles between islands

Our facilities manager for our College of Medicine labs asked me this
question, which I thought DCHAS-L might have some helpful input on:

Does anyone know of a "regulation" which would require limiting the
length of a lab peninsula (meaning the lab benches create only one
means of egress from the enclosed area) to require an island station
above that length? While such a rule makes sense, I am unable to find
any supporting information. Thanks for your assistance.

Thanks for any information.

Walking time/distance to a safety shower could be a limiting factor.

NFPA 101 and accompanying book of application/interpretation covers your
inquiry.  May not have the force of "regulation" in your jurisdiction as
these are consensus standards that have to be adopted.../dab

I am not aware of anything concerning the lab bench....but OHSA does  
have regs on egress

There may be life safety codes - your fire marshal can advise you.
Per ANSI you need to be within a 10 second travel time from
eyewashes/sowers (~55 ft)

I may be wrong, but I believe this is dictated by the fire codes, and  
is dependent on a few things such as sprinkler systems and "business"  
class.  I found what I believe to be the applicable code under a  
title called "Dead End" in the portion of the Seattle Fire Code that  
deals with Egress.  This was just a quick look on my part, but I  
would check your local fire code.

Below is the response from Stanford Fire Marshal.

Larry Gibbs


I am not aware of any code requirements that would limit the length  
of a lab
peninsula. Overall, for labs, the code does limit the length of travel
distance to an exit or exit-access door to 75 feet .

Not sure if this helps.
