What are the hazards associated with jet blast and prop wash, and how can you mitigate them?

• A. They can cause injury or debris; stay clear from engines exhaust and propellers, stay in designated areas, and keep away from wingtip and nose arcs.
• B. They are not dangerous.
• C. They only affect people wearing hearing protection.
• D. They only apply to large jets.

Answer: (A)

Jet blast and prop wash create dangerous, high-velocity airflow from engines and propellers. This force can injure people, knock them off balance, and blow debris or light objects into nearby areas, which is why staying out of the direct path of the exhaust and away from the propeller arcs is essential. The best way to mitigate these hazards is to remain in designated safe areas, follow all posted barriers and ground crew instructions, and keep well clear of both the engine exhaust and the wingtip and nose arcs where the airflow is strongest and unpredictable. It’s not accurate to say they aren’t dangerous, and protection for hearing won’t prevent the physical hazards of jet blast or prop wash. Also, these hazards aren’t limited to large jets; any aircraft with engines or propellers can produce dangerous blast.
