Proper Spacing for Private Fire Hydrants?

9/3/2020

7 Comments

 
Is there a standard spacing for private fire hydrants?

No applicable code for this project, but looking for guidance in what would be common under NFPA 24, NFPA 1 / 101, and/or the IBC. Thanks in advance.

No more than 600 ft. Most fire apparatus carry 800 ft LDH. Should also check with the AHJ about connections. They may also provide spacing guidelines.

This is covered in IFC 218. It is park of the appendix sections. Table C102.1 and Appendix C103

NFPA 850 - 300 ft spacing for main industrial areas, 500 ft spacing for remote areas

NFPA 101 does not contain any requirements for hydrants. Since you state no codes are applicable, I would say you have a choice of IFC or NFPA 1. I would look at Chapter 18 of NFPA 1 or Chapter 5 and Appendix B in the IFC. Outside of that, you may also want to consult with the property insurer to see if there are any requirements they may have that exceed minimum code. Also consult with the local FD to assess their capabilities and if going above minimum requirements would better accommodate their ability to address this facility you are dealing. Regardless of which code you use, you might need to assess the required fire flow (RFF).

In line with IFC, Fire hydrants should be spaced at a maximum of 90 meters (300 feet) from each other along the travel path of the adjoining roadway available for use by fire apparatus. A fire hydrant capable of meeting the system demand must be located within 30 meters (100 feet) of any required fire department connection installed in a new building.

The spacing/location of the fire hydrants would depend on the fire-flow requirement and number of hydrants required. See Appendix C sections C102, C103, and C105 of the 2012 International Fire Code.

If any industrial building has designed to install wet type Indoor Class III - Fire Hydrant or Standpipe system,

in those case is it mandatory to install outdoor type Fire Hydrant System such as Pillar Hydrant System along with outdoor Fire Hydrant box?

If it is mandatory then how many pillar hydrant need to be install , how the qty can be measures?

Please share the refernce from NFPA or any other valid source or ref.
