NFPA 13 2007 SEC 8.3.4.3 Makes reference to galvanized piping on dry systems when using k=4.2 spkr heads. Does galvanized piping mean just the pipe or the pipe and fittings
Thks Stookeyfpe - I don't have a copy of NFPA 37 - Could u shed a little light on it's requirements.
I will confirm if the supply will be from the bottom or top.
I have a Diesel Gen Room in a new fully sprinklered hospiital. There are two generators with one 250 gal diesel fuel day tank (elec consultant has yet to determine if he will have one daytank serving both or two tanks 250 gal tanks). Is the appropriate sprinkler system design Ord Gp 2 or Extra...
These are two different situations but both are small buildings that contain the diesel generators. The small gen buildings are roughly 100 ft from the main building. Yes, the main building is fully sprinklered including the room that contains the electric fire pump.
I have two situations -
1.A diesel generator building approx 400 ft2 separate from the main building - Does the Gen Building require sprinkler protection?
2. A diesel generator building seperate from the main building with an electric fire pump in the main building backed up by the generator -...
Because Sec 11.2.3.1.4(3) essentially states that if 11.2.3.1.4(4) are not met but the construction requirements of Sec 8.15.1.2 and 8.15.6 are THEN the design area is increased to 3000 ft2 in the adjacent areas.
In this case the combustible concealed spaces meet 8.15.1.2.6 but as such, are not filled completely with insulation, therefore, as per section 11.2.3.1.4(3) are met then the design area in the adjacent space requires the increase in design area to 3000 ft2.
NFPA 13 - 2007, Sec 11.2.3.1.4 (3) that unless sec 11.2.3.1.4.4 is met tnen the design area is to be increased to 3000 ft2 for the systme or portion of system that is ADJACENT to the qualifying combustible concealed space. If this is a ceiling space then is the ADJACENT space the rooms below it...
