Describe the ceiling more clearly. Is there drywall attached to the bottom of the joists of the light hazard offices?
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Russell Sent: Friday, September 07, 2007 2:00 PM To: AFSA Subject: Concealed spaces I have an all steel building (rigid rafters and z-purlins) open to the roof deck with sprinklers at the deck. On the floor below is an "island" of several offices with a gypsum ceiling attached to composite wood joist topped with 3/4 " decking which forms the floor of a mezzanine above these offices. This non-sprinklered concealed space requires of course the 3000 sq. ft. remote area in the adjacent areas. Does this mean that the system at the roof deck 15' above this mezzanine must be calculated using the 3000 s.f. area size?
