D.
solid foam.
8. A fire on an elevated object such as a wall or billboard is best attacked with
A. roll-on
B. rain-down
C. bank-down/bounce-off
D. drop down
9. Which element of the fire tetrahedron is not affected by a blanket of foam?
A. Fuel
Answer (2)
The best method to attack a fire on an elevated object is to use the bank-down/bounce-off technique, which safely discharges foam or water to extinguish flames. In the fire tetrahedron, foam does not affect the fuel element, which means the fire can reignite if the fuel source remains. Understanding these techniques and concepts is critical for effective firefighting. ;
The best method to extinguish a fire on an elevated surface is C. bank-down/bounce-off, which safely directs foam or water to the flames. In the fire tetrahedron, foam does not affect the A. Fuel element, leaving a risk for re-ignition. Understanding these techniques is crucial for effective firefighting.
