air into a confined space containing oxygen-deficient products of incomplete combustion
Backdraft - ✔✔ANSWER✔✔>>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 - ✔✔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
