Question 10

What are the 4 tactical approaches to a Tanker Truck Incident

Answer 10

1. ) assemble the resources and extinguish the fire with Class B foam. Be sure an adequate foam and water supply is available before initiating the attack.
2. ) Second, for combustible liquids, extinguish the fire with water fog when it can be done without creating environmental problems with the runoff.
3. ) protect adjacent exposures, and allow the fuel to burn itself out.
4. ) un-ignited leaks and spills should be diked immediately at a safe location and the liquid covered with foam to suppress and control the flammable vapors.
