About
fire fighting foam involve flammable or combustible liquids, cannot be extinguished by water alone. To cope with Class B fires, fire protection professionals have developed special firefighting foams. Foam can be used to extinguish fire, prevent ignition at flammable or combustible liquid spills, control vapors at hazardous materials spills,l and fight Class A fires. To be effective, it is important that foam be prepared and applied correctly. The purpose of this film is to objectively teach emergency responders what they need to know to select, prepare and apply foam to a Class B fire or hazardous materials spill. About the film |
The program
emphasizes the value of pre-incident planning, and tells how to analyze
a site to determine what type and quantity of foam concentrates to
keep available and what other factors should be considered in planning
an emergency response. Specific information is provided on preparing
foam, including proportioning to achieve the right mix of water and
concentrate and equipment necessary to mix and deliver finished foam.
Foam vehicles, specially designed equipment to bring foam to the incident,
are discussed. Responders are taught to apply the foam gently and
from a distance, extinguishing one small area and moving progressively
to secure the rest.
"Foam" tells how to calculate exactly how much concentrate will be needed to attack a spill fire, and warns that you must have at least this much foam concentrate and water available before starting extinguishing operations. Other topics covered include foam compatibility, using cooling water to protect exposures, protecting the integrity of the foam blanket, eliminating the source of the leak, fighting tank fires, and the special hazards of chemical fires.
