What are the three A's of fighting fires?

Never heard of this one, but I am familiar with the Fire Triangle- Heat, fuel or combustibles, and oxygen or air. remove one component, and the fire should be contained. the Fire triangle also was used by some labor unions not related to fire control.-as a sort of emblem. It is always an upright isoceles triangle, never the inverted or G-string type associated with, say, the Hudson automobile, YMCA logo, State Police of NJ, to name three examples.
