(not leading) through the open air parking

[sunyaer]

This is from Ontario building code division B part 3:

-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
3.4.4.1. Fire-Resistance Rating of Exit Separations
.....

(5) The path of exit travel may lead from an exit door or exit enclosure through open air parking that is located below a roof or floor assembly that is part of the building served by the exit door or exit enclosure where,

(a) the portion of the path of exit travel that leads through the open air parking is not more than 9 m in length measured from the exit door to a point at ground level at the perimeter of the building,

(b) measures are taken to prevent vehicles intended to park in spaces adjacent to the path of exit travel from encroaching on the path of exit travel, and

(c) an alternate means of egress not leading through the open air parking is available from the interior side of the door opening onto the path of exit travel through the open air parking area.

--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

In (c), the beginning part says "an alternate means of egress not leading through the open air parking", while the ending part states "... through the open air parking area", Is there a conflict of wording "not leading through" and "through"?

 

[ICE]

(c) an alternate means of egress not leading through the open air parking is available from the interior side of the door opening onto the path of exit travel through the open air parking area.

The alternate means is available from the interior side of the door opening onto the path of exit travel through the open air parking area.

ICE got it, your emphasis on the clause was in the wrong place. Basically, they need to make sure the parking garage is still intact as an exit (why it needs a fire rating), but if there is an alternative exit when you get to the door into the garage, we don't need to rate it anymore.
