Approaching or Leaving a Helicopter SAFETY  AROUND HELICOPTERS Do not approach or leave without the pilot’s visual acknowledgment. Keep in pilot’s field of vision  at all times. Observe helicopter safety zones  (see diagram at right). If blinded by swirling dust or grit,  STOP —crouch lower, or sit down and await assistance. On sloping ground, always approach or leave on the  downslope side for maximum rotor clearance. If disembarking while helicopter is at the hover, get out and  off in a smooth unhurried manner. Do not approach or leave a helicopter when the engine and rotors are running down or starting up. Carry tools, etc., horizontally below waist level—never upright or on the shoulder. Proceed in a crouching manner for extra rotor clearance. Hold onto hat unless chin straps are used.  NEVER reach  up or chase after a hat or other articles that blow away.
