of a boat
,◉ After-market Equipment. Answer: A type of device in a vehicle,
which can cause an electrical overload to factory installed wiring
◉ Alive and Breathing. Answer: Evidence of smoke or soot in the lungs,
bronchi, and trachea is one of the most significant factors in confirming

◉ ASTM. Answer: The organization that develops standard methods for
testing materials
◉ Auto-ignition. Answer: Initiation of combustion by heat but without a
spark or flame
◉ Backdraft. Answer: A deflagration resulting from the sudden
introduction of air into a confined space containing oxygen-deficient
products of incomplete combustion
◉ Backfire Flame Arrestor. Answer: A boat device that owners fail to
keep clean, which is a frequent cause of engine compartment fires on
boats
◉ Ballast. Answer: A device on a fluorescent light fixture that
transforms the voltage from normal household voltage to a higher
voltage
◉ Battery. Answer: The starter motor draws its energy from this source
