Anyone with info. on water spray nozzles for the protection against overheating of bulk propane storage tanks in the event of a fire from such tank?

RE: water spray nozzles

There is an NFPA standard for this, but I do not know the number of the document.

RE: water spray nozzles

What type of info are you looking for?  Have you talked to Grinnell or the other major fire protection companies?

RE: water spray nozzles

(OP)
Steve Braune_yes I know about nfpa 15 but my edition is 1985. Altho,I do not expect significant changes to whatever current edition that may be, I am particularly interested about manufacturers and the rating of their products.

RE: water spray nozzles

(OP)
td2k- no I have not contacted Grinell. Info. such as K factors, area of application per head, minimum pressure requirements, heat tolerance(anyword I much temp can such spay nozzle can take before deteroirating) if such nozzle were on a dry riser.

RE: water spray nozzles

chic,

As I recall, bulk propane tanks do not typically require a water spray for fire protection. (This, of course does not prevent you from installing such a system)

Fire protection for propane tanks (and LPG tanks)is discussed in NFPA-58 and 59.

The recommendations of the NFPA people are: 1) based on storage capacity, space the tanks properly....keep them from people and buildings 2) install excess flow check valves to limit the propagation of a blaze.

For a frightening read on a propane tank disaster, review the Herrig Brothers turkey farm fire on www.csb.gov

The link is:

Anyone else have anything to add about bulk propane fire protection ?

RE: water spray nozzles

MJCronin-unfortunately fire marshall wants spray nozzles because the tank is located in a somewhat populated rural area where 1)there is a lack of nearby municipal water supply 2)the town relies on a volunteer fire department which has marginal fire fighting equipemnt eventho of the mutual aid available.  Also current FSA per NFPA 58 is mentioning it as one possible solution.

RE: water spray nozzles

(OP)
This is an update to the situation- the tank is to be buried-fire protection problem solved.

RE: water spray nozzles

chic,

I am very much interested in the details of this propane tank installation...

How big is the tank ? How deep is the burial and how did you decide the depth ? Did you refer to any codes, standards, or guidleines for the installation ?

What coatings did you use on the tank ? Was there a
double containment ? How is the area above the tank controlled ?

My curiosity only...

MJC
