, • After-market Equipment -✓✓ A type of device in a vehicle, which can cause an

the fire growth, the total heat released, and WHAT?
• Arc-fault circuit interrupter -✓✓ What does he term AFCI stand for? And, the "A"
specifically represents what?
• ASTM -✓✓ The organization that develops standard methods for testing materials
• Auto-ignition -✓✓ Initiation of combustion by heat but without a spark or flame
• Backdraft -✓✓ A deflagration resulting from the sudden introduction of air into a
confined space containing oxygen-deficient products of incomplete combustion
• Backdraft -✓✓ An explosion caused by a combination of combustible materials heated
to the ignition point and a sudden introduction of oxygen to support combustion
• Backfire Flame Arrestor -✓✓ A boat device that owners fail to keep clean, which is a
frequent cause of engine compartment fires on boats
• Ballast -✓✓ A device on a fluorescent light fixture that transforms the voltage from
normal household voltage to a higher voltage
• Battery -✓✓ The starter motor draws its energy from this source
• Beyond a Reasonable Doubt -✓✓ The burden of proof in a criminal trial
