The replies I received in response to this morning's inquiry. Thanks to everyone for their quick response... - Ralph Date: Wed, 9 May 2007 11:41:09 -0400 From: Ralph StuartSubject: [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. - Ralph Ralph Stuart, CIH Secretary, ACS Division of Chemical Health and Safety Environmental Safety Facility 667 Spear St. Burlington, VT 05405 rstuart**At_Symbol_Here**uvm.edu == From: Jeff Your Subject: Re: [DCHAS-L] Length of aisles between islands Date: Wed, 9 May 2007 11:57:01 -0400 (EDT) Walking time/distance to a safety shower could be a limiting factor. -- Jeffrey A.

McLouth" 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) Larry From lucydillman**At_Symbol_Here**comcast.net Wed May 9 13:56:49 2007 From: lucydillman**At_Symbol_Here**comcast.net Subject: Re: [DCHAS-L] Length of aisles between islands Date: Wed, 09 May 2007 17:56:45 +0000 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.

Larry Gibbs Larry, 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. Joe Joseph Leung, P.E.
