Let the crew open and close doors and compartments. Remain forward of the winglets. To move from one side to the other always cross in front of the helicopter. Don't touch the tubes projecting from the nose of the helicopter. Carry long objects, such as IV poles, parallel to the ground to avoid contact with the rotor blades.
Ensure vehicles are clear of the helicopter's departure path.
Dowse all bright lights or redirect them away from the helicopter prior to night takeoffs. Protect yourself from blowing debris. Shield face and eyes.
