g. Examine the exposed insulation of an insulating boom for cuts, unusual discoloration,
or other signs of damage prior to use or at any time damage is suspected.
h. Inspect the remaining portions of booms, sheaves, cables, fittings, bucket, and bucket
liner for defects.
Insulated buckets are required for work in accordance with Table 31. An
insulated bucket of an aerial lift is provided with a conductive bucket
a. The liner, usually a metallic screen, should completely surround the bucket walls and
floor to provide electrostatic shielding for the occupant. Tools and other equipment carried in the
bucket should be stowed carefully to avoid damaging the liner.
b. Insulated buckets should be subjected to Electrical Insulation tests in accordance with
the requirements set forth in: the equipment manufacturer's technical manuals/instructions;
NAVFAC P-300, Management of Transportation Equipment, Section 4.11.5; and American
National Standards Institute ANSI A92.2, Vehicle-Mounted Elevating and Rotating Aerial
Platforms. Insulation tests should also be conducted each time a higher voltage (than the
insulated bucket is certified for) is worked, and when conditions indicate a need for insulated
tests. Records of all tests should be maintained. Work operations will be suspended immediately
upon any indication of a malfunction in the equipment.
Aerial Lift Maintenance
Perform periodic maintenance in accordance with the manufacturer's
operations and maintenance manual. Perform electrical tests on insulation
no less than every 6 months.
