37. Also known as rollover. A condition where smoke and gases ignite and spread.

38. Flame Spread

39. The movement of the fire away from the ignition source.

40. Flammable or Explosive Limits

41. The percentage of a substance in the air that will burn once it is ignited.

42. Flashover

43. The phase between the growth stage and a fully developed fire when the radiant heat is so intense that all combustible materials in the room ignite.

44. Flash Point

45. The minimum temperature at which a liquid fuel gives off sufficient vapors to form an ignition mixture with the air near the surface.

77. Water Hammer

78. Potential damage caused by opening and closing nozzles and valves too quickly
