Extinguishing Class B Fires with PNS, an Environmentally-friendly Compound
Abstract
The objective is to refine PNS formulation and application to have an alternative to aqueous film forming foam (AFFF) for fuel fires that is ready for MILSPEC testing. PNS Syrup (PNS) is an environmentally friendly, proprietary fire extinguishing agent made by our company, PN Solutions. PNS is found to react with the ions and radicals in the flames and stop the chain reaction, suppressing the smoke and the fire. PNS is an effective fire extinguishing agent for large gasoline fires. We can extinguish large gasoline fires (28ft2 and 50ft2) in less than 30 seconds by applying PNS in a mist. Despite excellent fire extinguishing characteristics, PNS is a non-foaming liquid and as such, does not have adequate burnback capability. The main objective of this project has been to develop approaches for dealing with this limitation. In this report we will discuss our efforts and outcomes with three approaches for adapting PNS to achieve good burnback. We believe the resultant formulations may also be of use to other groups working to replace AFFF.
