Safety around aircraft

• Never walk near a propeller, even if the engine is stopped — treat every propeller as live.
• Jet engines suck air in at the front (intake danger) and blow very hot, fast air out of the back (jet blast).
• A red anti-collision beacon that is flashing means an engine is about to start or is running — keep away.
• Pick up any loose objects: FOD (foreign object debris) can be sucked into engines or burst tyres.
• Wear hearing protection and high-visibility vests on the apron; walk, never run, and follow the marshaller or ground crew.
• No smoking or naked flames near aircraft or refuelling.

Marshalling signals (basic)

Arms raised above the head with wands vertical = "this bay"; both arms moving up and back = "move ahead"; arms crossed above the head = STOP; one arm pointing down while the other moves = "turn".
