Which one of these is NOT considered a competent Aluminum-to-pavement sparks
ignition source?
Metal-to-metal sparks,
Aluminum-to-pavement sparks,
Metal-to-pavement sparks,
Motor bearing sparks
A meaningful analysis of a fire requires an Heat Release Rate
understanding of the fire growth, the total heat
released, and WHAT?
What does he term AFCI stand for? And, the "A" Arc-fault circuit interrupter
specifically represents what?
The organization that develops standard methods for ASTM
testing materials
Initiation of combustion by heat but without a spark or Auto-ignition
flame

of air into a confined space containing oxygen-
deficient products of incomplete combustion
An explosion caused by a combination of combustible Backdraft
materials heated to the ignition point and a sudden

exceeds atmospheric pressure
*And this is the most common mechanical explosion
The temperature or point at which the vapor pressure Boiling Point
of a liquid equals the external pressure applied

conductive objects
Most engine fires typically penetrate the interior Bottom Passenger Side of the Windshield
compartment at this location of the vehicle
