Special design consideration must be given to buckling of tank wall and heads, the hold-down lug system, and top and bottom knuckle requirements. The hoist wire should be connected to the top lifting lugs, and the tank should be raised carefully, using guide ropes to prevent sudden swinging.
Full protection must be provided when using chains or cables. Other test methods for determination of hoop properties may be used when the fabricator can verify the validity of the selected method.
