Sprinkler system for a warehouse with apex height of 22m
Sprinkler system for a warehouse with apex height of 22m
(OP)
Hi,
I am involved in a project to design sprinkler system for a large warehouse. Some dimensions are as follows:
Apex height: 22m
Eave height: 14m
Height of storage: 12m
Types of racks: The racks consist of three rows (the height of each row is 4m)
Type of storage: encapsulated, class III
Now, my questions:
1) I cannot find anything in NFPA 13 to cover sprinkler design regarding this roof height (=22m). Can you give me some hints or references?
2) Can I use ESFR sprinklers in this project? If yes, do I have to use intermediate sprinklers? And in how many levels do I have to install sprinklers?
Many thanks

See
16.3 Protection Criteria for Rack Storage of Class I Through Class IV Commodities Stored Over 25 ft (7.6 m) in Height.
and then look at
12.1.3.4 Excessive Clearances.
You can NOT use ESFR

Do not forget the Reliable ESFR product good for 43' storage height in a 48'high building, see below for details. Note the minimum aisle width.
Link
The HL22 Specific Application ESFR sprinkler is intended for installation in accordance with the specific application sprinkler criteria referenced in NFPA 13. This sprinkler is intended for protection of Class I to IV Commodities and cartoned unexpanded Group A or B plastics. The storage can be palletized and solid piled, open frame single row or multiple row and portable rack storage for storage heights to 43ft. (13m) in buildings with ceilings to 48ft. (14.6m) high and minimum 8ft. (2,4m) aisle width.
This product would not help sprintler11 since his ceiling is 72'.
