NFPA reference for foam concentration percentage
NFPA reference for foam concentration percentage
(OP)
Hi to all,
I would like to know if there is any international code like NFPA that defines foam concentration application. I have seen in NFPA 16 foam concentration percentages such as 1%, 3%, and 6%. How do I determine which concentration percentage shall I use for a certain application?
Thanks!

A fire fighter knows that having a foam with the ability to work fine with 1%-3%-6% gives the option to choose a better performance for different fire scenarios. For example for a wild fire foam may work fine with a concentration of 1%, just to be used as a wetting agent and save foam. For a fire in a small dike with gasoline, using 6% with give you a thick foam that will last better. Of course the manufacturer has to certify with tests that the foam will work fine in specific cases.

Packaging is another major component of the hazard assessment. See NFPA 30 Chapter 16 for the various decision trees and you will find that the container's material of construction and it's pressure relieving design (or lack of) will dictate the required fire protection.
Seek professional engineering assistance if you cannot perform this hazard analysis.
