as well as technical manual requirements (where applicable), plus the following:

a. General.

(1)

Check for proper markings.

(2)

Check for evidence of mishandling and or damage.

(3)

f. . Wire Rope. Refer to Appendix A, paragraph A-3.e.

g. Chains. Refer to Appendix C, paragraph C-2.b.

B-3. Tests. When required by paragraph 4a, perform a functional test to determine operability of

the equipment. Functional testing shall consist of lifting a characteristic load (determined locally),

holding it at an appropriate height for one minute, maneuvering it in a manner which will simulate the

operation of the lifting device in the working environment, and lowering it to its original position. For

lifting devices used to handle hazardous materials, conduct the function test as above, using an inert

item equal in weight to or heavier than (not to exceed the manufacturers load rating of the device) the

heaviest item normally lifted by the devices as its characteristic load. A visual inspection will be

performed prior to and after functional test is performed. Record pretest and post-test findings,

actions taken, and test date in the end item's historical records.
