We feel F-500 EA is a more versatile product. The same F-500 EA can be used on Class A, Class B polar, Class B nonpolar, Class C (transformers and high-voltage car fires) and Class D fires. Three different foams are required for Class A, Class B polar and Class B nonpolar. Additional products are generally used on Class C and D. And then there’s three-dimensional fires.

NFPA 11 specifically states “Foam is not suitable for three-dimensional flowing liquid fuel fires or for gas fires.” Because the foam blanket traps in the heat, foam is very poor at cooling. Also, much more agent and water is required for foam over F-500 EA. You can expect fewer callbacks for rekindles because F-500 EA reduces the temperature below autoignition temperatures. Also, F-500 EA doesn’t create the scalding steam associated with fire extinguishment; instead, F-500 EA results in a warm vapour at about 140°F. That alone can mean fewer workman’s comp claims.

As F-500 EA encapsulates the free radicals, there is less toxic smoke and improved visibility. Finally, for hydrocarbon spills, F-500 EA encapsulates the fuel, making it safe, whereas foam needs to be re-applied to prevent the blanket from breaking down.
