To remember the rules of fighting fires just remember the three A's Activate Assist and Attempt. True?

The three A's for remembering fire response are indeed Activate, Assist, and Attempt. "Activate" refers to alerting emergency services, "Assist" involves helping others evacuate if it's safe to do so, and "Attempt" relates to trying to extinguish the fire only if it's small and manageable. However, personal safety should always be the priority; if the situation is too dangerous, evacuating is the best course of action.
