(a) You must ensure that the load is well secured and properly balanced in the sling or lifting device before it is lifted more than a few inches.
(b) Before starting to hoist you must note the following conditions:
(i) Hoist rope must not be kinked.
(ii) Multiple part lines must not be twisted around each other.
(iii) The hook must be brought over the load in such a manner as to prevent swinging.
(c) During hoisting you must take care that:
(i) There is no sudden acceleration or deceleration of the moving load.
(ii) The load does not contact any obstructions.
(d) You must ensure that cranes are not used for side pulls except when specifically authorized by a responsible person who has determined that the stability of the crane is not thereby endangered and that various parts of the crane will not be overstressed.
(e) While any employee is on the load or hook, you must ensure that there is no hoisting, lowering, or traveling.
(f) The employer must require that the operator avoid carrying loads over people.
(g) The operator must test the brakes each time a load approaching the rated load is handled. You must test the brakes by raising the load a few inches and applying the brakes.

Extreme care must be exercised; the block must be "inched" into the limit or run in at slow speed. If the switch does not operate properly, the appointed person must be immediately notified.
