Buried plastic tanks for fire suppression water storage
Buried plastic tanks for fire suppression water storage
(OP)
I have read NFPA 22, which does not list plastic as an allowable material for fire suppression water storage in Section 4.4. However, equivalent designs are permissible in Section 1.4.
1.4 Equivalency. Nothing in this standard is intended to prevent the use of systems, methods, or devices of equivalent or superior quality, strength, fire resistance, effectiveness, durability, and safety over those prescribed by this standard.
Is anyone aware of applications where a buried plastic tank, where the soil cover provides a 2-hour fire rating, can be deemed acceptable relative to Section 1.4 above?
Also, is anyone aware of widespread use of plastic tanks for fire suppression water storage, and if so, where in the United States have you seen this application used?
Thanks!

NFPA 22 Chapter 11 (FRP tanks have been in there since the 1993 edition, I believe)

The only place I've used plastic tanks is for 13D applications where it is a combined tank/pump setup that works on 120V electrical service.

If you use a vertical turbine pump, then you can have the buried tank.
