Class III and IV commodity Palletized on double rack for the distance of aisle i will oblige the right one because the building is not yet built roof height 10.2 meter storage height 8 meter roof: concreet with beems 125cm, 40cm and 20cm height

from your point of view you are right, but i work in Morocco and there is no one that demand i NICET certification also there is no one that give that sertification in Morocco. and for now i work on a project of installing sprinkler system on a big commercial surface (exhibition+storage in...

Can we use spray sprinkler on double rack storage?

what is the distance between sprinklers and the roof or ceiling? and tne lenght of the nippel?

I draw somting in "paint" take a look at it ant tell me if it's wrong! http://files.engineering.com/getfile.aspx?folder=3e78dddd-1e9c-477a-9d62-6f0504a1e851&file=distances_from_column.bmp

what's the distance between pole support made frome steel(I-beam) and a sprinkler? I found in NFPA 13 distances between Suspended or Floor-Mounted obstruction but not pole support that are mounted in the floor and in contacte with the roof.

how can I know in a situation that I have to choose pendent or upright sprinklers? are there any situation that is better to install upright sprinkler or pendent?

I didn't find in NFPA 13(ed 2007) the allowable distances between sprinklers in the case of "large drop sprinkler" and "ESFR" installed in Hight storage. all I found is the distances for "standart pray sprinkler" ,see table 8.6.2.2.1(d)

it's to stor wood furniturs( chairs,cupboard,desk...) but I don't know how are they stored

So if i understant what's in the 22.4.4.3 NFPA13, the design area should be at least 960sqft

In the case of large drop and ESFR sprinkler system disigned for storage table 14.3.1(a)and 14.4.1 from NFPA13 (ed 2007), how can I find the design area ? I look in the NFPA 13 and didn't find the design area for tha case.

no it's a standard spray sprinkler

I have a simple question. For example if I'm in the case of designing automatic sprinkler for storage and work with the table 12.2.2.2.1(a)NFPA13(ed 2002) how can I detemine the shape of the design area and number of prinklers in each branch lines? My suggestion is to apply 14.4.4.1.1 NFPA13(ed...

thank's for the explanation. what I understand is that the big difference is at the installation of the system. As you expected, it's the same thing here in Morroco, there are no professionals in sprinkler systeme. For me I am in training and I face a lot of broblems in understanding NFPA13...
