4.1.5 Procedures. Whenever possible, a written procedure shall be provided to the
crew for each different type of work prior to initiation of the work. Specific written
procedures shall be provided for major programs, particularly substation
maintenance and complex transmission line functions, Procedures shall not be
arbitrarily disregarded or changed during the actual work. Procedural changes
during the work program shall be carefully developed through discussion among
well-trained craft and supervisory personnel, with the original procedure-writer
participating, if available. Procedures shall be continuously examined and updated
to take advantage of new equipment and work methods.

4.1.7 Inspection Measures. The equipment shall be regularly and thoroughly
inspected in accordance with manufacturers' and/or operating office's instructions. A
rigid preventive maintenance program, including appropriate maintenance
checklists, shall be initiated and carried out. These maintenance checklists shall be
maintained in the responsible operating office.

4.1.8 Conductive Clothing. Personnel using this technique shall wear conductive
footwear. Approved conductive clothing may be used at any time, but it shall be used
for all barehand work at 200 kilovolts phase-to-phase and above, or when specified.

4.1.9 Minimum Distances. When approaching, leaving, or bonded to an energized
part, workmen shall maintain themselves and their support platforms at a distance
from grounded parts no less than specified in column (a) shown in the table on the
following page. Also, the minimum phase distance as specified in column (b) below
shall be maintained from the workmen and their support platforms to other phase
conductors. The minimum phase-to-ground and phase-to-phase distances may be
cumulative during nonbonded operations.

4.1.10 Handlines and Conductive Materials. The use of handlines between
personnel-support equipment and the ground is prohibited. Approved
nonconductive-type handlines may be used from line to ground when not supported
by the support platform(s). The nonconductive-type handlines shall be stored and
protected from foreign matter by use of nonconductive canisters. No conductive
materials over 3 feet (1 meter) long shall be placed on support platforms except
appropriate length jumpers, armor rods, and approved tools.
