What is the crash axe primarily used for in terms of egress?

The crash axe is primarily utilized as a last-resort method for egress during emergencies. In situations where conventional exits are blocked or compromised due to an accident or a fire, the crash axe can be used to break through barriers, allowing crew members and passengers to escape the aircraft safely. Its design allows for effective use in cutting through aircraft structures, making it a vital tool in critical circumstances where time is of the essence.

In contrast, a standard exit tool is typically designed for routine evacuations and is not intended for emergencies involving obstructions. Routine maintenance and repair tasks do not pertain to the use of a crash axe, as these activities are usually performed with different tools and equipment suited for upkeep rather than emergency egress.
