So I'm not really missing pages, however some of the information I thought would be contained in chapter 17 doesn't seem to be in there. There seems to be extensive information related spacing, fire rating requirement and hydraulic calculation requirements for the various storage of liquids within NFPA 30, however there doesn't seem to be such criteria for Processing Facilities.
Can anyone advise where one goes for criteria for an internal processing facility utilizing flammable and combustible liquids (both miscible and immiscible) in regards to: Max allowable spacing of sprinklers? Do you have to flow all sprinklers within a fire area (i.e. including sprinklers under platforms, under obstructions, over the liquid pumps)? What is the required calculation area and density? I see 3.3.2.2 defines a Fire Area as 'An area of a building separated from the remainder of the building by construction having a fire resistance of at least one hour and having all communicating opening properly protected by an assembly having a fire resistance rating of at least one hour. However, if you have a large area and trench drains are provided to prevent spill fires, what is the maximum area to calculate? First NFPA job in 3 years and it would be one that I'm familiar not with. Any insight would be greatly appreciated. Regards. Damien Shannon Provincial Sprinkler Company Ltd.
