Is this a multiple story building? If so, don't you still have to protect the landings where egress and access happen?? Regardless of combustible finishes?? NPFA 13; 8.15.3.3

Floor coverings, specifically carpet is considered interior finish pursuant to 2006 IBC 804.4 and as such Class I (I-1 and I-2) , Class II materials (A,B,E,H,I-4,M,R-1,R-2 and S) and DOC FF-1 compliant in all the others. The exception allows interior finish requirements to be bumped down one grade where a building is equipped throughout with an an automatic sprinkler system in accordance with 2006 IBC 903.3.1.1 or 903.1.2. 903.3.1.1.1 -4. Exempts "In rooms or areas that are of non combustible construction with wholly non combustible contents". So if the interior finish materials meet the non combustible criteria then sprinklers are only required at the top and bottom levels of a non combustible stair. Someones got to go back to the carpet manufacturer for the answer. PS, Change Stair Shaft to Stair Enclosure. Hope that helps John Drucker Fire Protection Subcode Official (AHJ, not a scientist ;-)) New Jersey -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Margaret Zabel Sent: Thursday, July 31, 2008 11:39 AM To: Sprinkler Forum Subject: Stair shafts Using NFPA 13-2002, paragraph 8.14.3.2 describes the requirements for sprinklers in non-combustible stair shafts. Would a non-combustible construction stair shaft (concrete stairs, sheetrock/rated walls) that has carpet on the landings and stair treads be considered "non-combustible"? Assuming the stairs are over 4'-0 wide, should there be sprinklers located throughout the shaft -- below treads and stairs?
