The part of the fire that spreads most rapidly and does the most damage.
What is the head?
The question is: What is carbon monoxide?
What are the components of the fire tetrahedron?
Transfer of heat through direct contact
What is Conduction
Occurs when the flow of water in a hose line is stopped suddenly resulting in a water surge.

This device can be activated to immediately give an audible alarm when a firefighter is in distress.
What is a PASS device
The area where the fire started.
What is the origin?
An explosive ignition that can occur when air is allowed to mix with hot, unburned fire gases.
