Fire Protection Systems

Hi Arend,          Thanks for your kind replay. Please note that we don't have any issue on testing at 0GPM & of course discharge pressure will be always high more then the design pressure. Our issue is while testing the diesel pump  at 100% rated flow result comes only 50% of design pressure. As per AHJ it should be minimum 95%. Hope you can…

Hi Travis:   Your question needs a lot of discovery of the facts before a meaningful answer can be found.   I would say be cautious before removing this passive fire protection feature. NFPA 101, Life Safety Code says you may be able to remove the fire door if is not required in the new construction requirements and the building complies with…

Always more to add:   I not sure about the question. It was not clear that the question may be asking the building area would be limited by NFPA 13. It is my understanding that NFPA 13 does not limit the area of a building based on the hazard classification. Looking at Section 8.2.1 of NFPA 13 limits the protected area of a floor on any one floor…

Hi John:   I would say the maintenance requirements for sprinklers in Table 5.1.1.2 of NFPA 25 used for the for the periodic inspection, testing, and maintenance references Section 5.4.1.7 that has the requirements for sprinkler maintenance used for protecting commercial-type cooking equipment and ventilating systems.   I looked very closely at…

Cannot give a good reply, but the 130 is the maximum allowed, and than that depends on a lot of other factors.   That is why I think it is a spacing question.         OHHH I am not an engineer, so you can discount my reply if you want

My main concern was installation of ESFR sprinklers with different K-factors on the same system, and separation of those sprinklers/design criteria.   To be more specific: The first scenario is an existing warehouse with K-14.2 ESFR sprinklers designed to discharge at 50-psi; 30-foot high building; storage of Class I-IV and unexpanded Gp. A…

Yes, lol. About 3 whole pages..   Nick Campbell

Look up NFPA 30 chapter 22 for fire protection requirements of aboveground diesel storage tanks. For the type of tank described, required fire suppression will depend on what might demand the insurance company, local fire department or even local laws.

D. All the above
