What role does a fire guard play during engine start procedures?

The fire guard plays a critical role during engine start procedures primarily by providing emergency response. This individual is stationed in close proximity to the aircraft while the engine is being started, prepared to react in the event of a fire or an emergency situation. Their presence helps ensure safety by being ready to activate fire suppression systems, alert personnel, and assist in evacuating the area if necessary.

During engine starts, particularly for jet engines, there is an inherent risk of fire due to fuel vapors and the heat generated by the engine. The fire guard is trained to recognize potential hazards and implement emergency procedures to mitigate risks. This role is essential in maintaining safety protocols and ensuring that any incidents are managed quickly and effectively.

While other roles such as assisting in operations, fueling, and the necessity of a fire guard may arise, they do not encompass the primary responsibilities associated with maintaining safety during this critical phase of engine operation.
