Fuel Type
Application rates will remain the same for all hydrocarbon fuels (at 0.10 gpm foam solution per square foot).
Polar solvents generally require a minimum .16gpm foam solution per square foot and certain polar solvents may require applications rates up to .24 gpm per square foot.
One issue which may remain mysterious until after the call is over: what was the truck actually hauling? Flames & smoke obscuring placards, burning shipping papers and an injured driver..... what fuel are we really dealing with?
There is not a classification system such as Lower, Medium or Higher polar solvents, only on this table to designate application rate categories.
If efforts are not effective given an anticipated fuel, consider higher application rates.
The following table provides a view of fuel differences/needed application rates on a 25'x25' fire (625 Ft²) and demonstrate the benefit of a 3%-3% foam concentrate Vs. 3%-6%.
