(5) shall not hanging from the top of the head through, hanging objects and the boom shall not stand on.

Fifth, in strict accordance with the command signal operation of the emergency stop signal, whoever issued, must be implemented immediately.

Sixth, hanging out near or rating, or lifting of dangerous goods (liquid metal, hazardous materials, flammable and explosive materials), the brake check carefully before lifting, and with a small height, try hanging a short trip, make sure there is no problem after then lifting.
