Blog Post created by cduffy Employee on Jun 19, 2015

 

6.1.2 of NFPA 14 protection of aboveground pipe criteria for standpipe systems. As Staff Liaison to the Technical Committee on Standpipes I often receive questions where users struggle to understand what must be protected and how it is to be accomplished. In an effort to clarify the issue the Technical Committee on Standpipes has proposed revisions to 6.1.2 for the 2016 edition. So, if you have questions on 6.1.2 please take some time to read the following changes as I hope these will help to clarify the requirements.

 

Replace Section 6.1.2 with text as shown below.

 

6.1.2 Protection of Aboveground Piping.

 

6.1.2.1* Standpipe system piping shall be protected from mechanical and fire damage in accordance with this section.

 

A.6.1.2.1 Standpipes should not be installed in non-sprinklered areas of combustible construction.

 

6.1.2.2* Standpipe systems shall be protected in accordance with Table 6.1.2.2.

 

A.6.1.2.2. Where pipes that supply combined systems in areas or buildings that are sprinklered, or are installed in non-sprinklered, combustible buildings or areas the piping should be protected. Protection of pipe should also be provided in any area of a structure or building that poses a degree of hazard greater than that normal to the general occupancy of the building or structure. This includes areas for the storage or use of combustibles or flammables; toxic, noxious, or corrosive materials; and heat-producing appliances.

1 - Refers to either a horizontal standpipe or the horizontal portion of any standpipe such as a feed main.

2 – AS = fully sprinklered building in accordance with NFPA 13

3 – NS = non sprinklered or partially sprinklered building

 

6.1.2.2.1 Protection shall consist of one of the following methods:

a.) Enclosure in a fire rated exit stairway.

b.) Enclosure in fire rated construction with such rating equal to that of the enclosed fire rated exit stairway.

c.) Listed fire wrap or other insulating material applied directly to the pipe with such rating equal to that of the enclosed fire rated exit stairway.

 

6.1.2.2.2 Where exit stairways are not required to be enclosed in fire rated construction, standpipe systems shall not be required to be protected.

 

6.1.2.2.3 Class II standpipe systems are not required to be protected.

 

6.1.2.2.4 Where additional standpipes are needed to meet travel distance requirements in non-high rise buildings, protection of piping is not required.

 

6.1.2.2.5 Seismic bracing, where required, shall be in accordance with NFPA 13.

 

6.1.2.2.6 Piping subject to mechanical damage shall be protected by steel posts, concrete barriers or other approved means.
