TESTING PROGRAM IN SUPPORT OF THE QPL
The Forest Service Classifies the Fire Chemicals as:
Long-Term Fire Retardant
Class A Wildland Fire Foam
Water Enhancers

CF was evaluated as a water enhancer to FS specification 5100-306a (l2/02).
The evaluation program was initiated in May 2003.
CF was approved and initially added to the QPL on April 5, 2005.
It is noted: CF is not a Gel as are the other water enhancers listed.

Testing was done at the Missoula Technology Development Center (MTDC) in Missoula, Montana as well as back-up testing for correlation at the San Dimas facility in California.

The CF concentrate, as well as the recommended field mixture, was evaluated. The outdoor storage consisted of one year subject to a freeze – thaw environment. Many of the test parameters were repeated in order to demonstrate no detrimental effect after long-term storage. Special testing was done by outside labs at Pacific Metallurgical Company, Stillmeadow Inc., U.S. Geological Survey and Underwriters Laboratory, Inc.
