HICOMBAT A
0.1% - 1% Class A Foam
Environmentally responsible HiCombat™ A Class A
foam
concentrate, is a unique new formulation providing
unmatched firefighting performance and flexibility.
HiCombat™ A is specially designed for use in Class A/B
foam systems and is excellent for Compressed Air Foam
Systems (CAFS). This environmentally responsible
formulation does not contain reportable components
under SARA Title III, Section 313 of 40 CFR-372, or
CERCLA.
WORKS
TWO WAYS
HiCombat™ A foam concentrate works in two ways. First,
HiCombat™ A improves the penetrating capability of
water. It reduces the surface tension of plain water, which
allows it to penetrate surfaces where water might normally
run off, to reach deep-seated fires. This helps reduce
the amount of water required to extinguish the fire and
also provides quicker knockdown. Secondly, HiCombat™
A increases the heat absorbing capabilities of water.
Foaming ingredients give water the ability to adhere to
vertical surfaces which allows the water longer contact
with the fuel. The longer the water is in contact with the
fuel, the more heat it is able to absorb. A coating of Class
A foam may also be used for exposure protection to prevent
fuels from igniting by raising their moisture content
and providing a tough protective barrier to an oncoming
flame front.
Features
• Meets USDA Forest Service Requirement per
Specification 5100-307.
• Environmentally responsible formulation.
• UL Listed as a Wetting Agent, at substantially lower
usage rates than most Wetting Agents.
• Premix is stable for more than 30 days (using potable
water), which is significantly longer than traditional
Class A foam solutions.
• Emulsifies Class B Hydrocarbon fuels.
• Contains NO alcohols for higher flash point and compatibility
with Class A/B Systems.
• Can be used with fresh, brackish and seawater, plus
exhibits good foamability, even in cold water.
