Foam maintains a longer wet contact time than a fluid.
Compressed air foam system advantages.
In rural areas where water supplies are scarce if exposure protection applications are needed more water remains available for offensive fire attack.
Cafs uses a class a foam concentrate combined with water and compressed air to form a fire extinguishing agent that is greater than the sum of its parts.
Recognized for its many advantages over water foam is also proven to be more effective than liquid in areas such as hazmat cleanup and decontamination.
The use of compressed air foam systems cafs in the rural setting undoubtedly offer great benefits as do regular class a foams for their penetrating and protective qualities.
Second the high energy of a caf stream provides a longer reach allowing firefighters to operate farther away from the incident in a safer location.
Increased reach equals increased safety.
Benefits of foam foam is quickly becoming the tool of choice for first responders around the world.
However we are now finding ourselves facing an in depth strategic review concerning our approach to structural firefighting where it has been shown that fire attack systems providing foam air additives can assist firefighters greatly.
Some of the benefits of foam include.
Typical components include a water source a centrifugal pump foam concentrate tanks a direct injection foam proportioning system on the discharge side of the pump a mixing chamber or device a rotary air compressor and control systems to ensure the correct mixes of concentrate water and air.
Compressed air foam clings well to vertical fire exposures which means less water is wasted from runoff during exposure protection operations.
