Developed by firefighters for firefighters, Fire Cap is an environmentally friendly
wetting agent that extinguishes fires rapidly and eliminates flashback. When mixed
properly with water, Fire Cap reduces the surface tension of water (see illustration)
which then expands the wetted surface area and promotes deeper penetration into
the seat of the fire. Besides putting out the fire, the incidence of heat, smoke, and
vapors is significantly reduced.

As a spill stabilizing agent, Fire Cap is an emulsifier that separates the chemical make-
up of a contaminant and then renders it non-volatile. In the process, the flammable
vapors of a contaminant are reduced or eliminated with no risk to firefighters or
HAZMAT personnel. Fire Cap is non-toxic, non-hazardous, and non-corrosive and is
effective against all classes of fires except electrical.

Water is Not Free
Water carries with it a number of related costs. Procuring, storing, pumping,
transporting, and ultimately disbursing water all require special equipment. By simply
reducing usage, the life of the equipment is extended which can mean thousands of
dollars saved. In municipalities where the water supply is scarce, the importance of
getting the most out of every gallon can’t be overstated.
Plain Water
High surface tension
of water causes a
bridging action over
the pores of the
material thereby
restricting its ability to
spread and penetrate.
Fire Cap Solution
Fire Cap wetting agent
makes water droplets
smaller and reduces
the surface tension
which expands the
surface area. Fie Cap
also facilitates deeper
penetration into the
seat of the fire.
