Oversized egress paths with secondary uses.

[ARCHITECTOM]

Something our office hasn't run into before-
Project is a 7000sf restaurant:
The owner wants hand wash sinks outside of the WC in a rear hall which also serves egress.
The minimum path width is 3'9" the hall is 5'1" wide, and the proposed sinks are 14" deep- so there is no projection into the required egress path.

The fire marshall stated the following:

"The plans I read show the sinks projecting into the space by 14” or 15”.

Fire Safety Code 7.3.2.2 Does not allow for projections into the means of egress greater than 4.5” . I don’t see an exclusion on an exit enclosure wider than minimum.

I see it still as a potential point of impediment"

I am looking for commentary on this but would love some thoughts.

 

[Mr. Inspector]

I don't know anything about the Fire Safety Code but the IBC section 1003.3.3 says you cannot have a protrusion more than 4" over any walking surface and if it is on an accessible route ICC/ANSI A117.1 section 307.2 doesn't allow more than a 4" protrusion into a circulation path. Both of these mean the whole hallway.

IPC section 405.4 requires the lavatory to be in the same room as the toilet.

Thank You-
ACTUALLY, REGARDING THE SECOND POINT:
1003.3.4 CLEAR WIDTH
PROTRUDING OBJECTS SHALL NOT REDUCE THE MINIMUM WIDTH OF ACCESSIBLE ROUTES AS REQUIRED BY SECTION 1004.

THIS IS ESSENTIALLY THE SAME ISSUE AS A WALL-HUNG WATER FOUNTAIN IN A HALLWAY- COMMON ISSUE IN A SCHOOL FOR EXAMPLE, AND CAN BE DEALT WITH VIA RECESSING, OR PROVIDING WING WALLS?

THE IPC ISSUE IS IRRELEVANT, AND CHANGES BY STATE: IN THIS CASE THESE ARE ADDITIONAL HAND SINKS- THE REQUIREMENTS ARE MET WITHIN THE BATHROOM FACILITIES. THESE ARE REQUIRED FOR RELIGIOUS/CULTURAL ISSUES IN THIS GIVEN FACILITY.

As long as you provide cane detection between 27 n 80" a 14" projection would not then be an issue.

 

[Mr. Inspector]

A barrier on both sides of the sink would make it work.

You need to comply both sections, IBC 1003.3.4 does not negate ICC/ANSI A117.1 section 307.2 which doesn't allow more than a 4" protrusion into a circulation path. The 2009 IBC that we use here does not have anything about accessibility in section 1004. What I codes do you use there?

This is projections in a corridor

Remodel of existing?...I don't think he should be citing NFPA for "construction"....

 

[steveray]

Tell him that 7.3.2.1 says that "the egress width is measured at the narrowest point".....So you do not have a projection....That'll make him steam....What Town?

Only 1 L in fire marshal...That'll make em mad too....

If it were an "exit enclosure", then no other functions or utilities allowed, but not for a corridor...
