5-4.12.2 Support the tool in a horizontal position during the test.
5-4.12.3 Avoid over-wetting. Use a mist applicator (such as a laundry-type spray
bottle) and spray the test section until drops just start to run down the surface. If too
much water is sprayed on the tool, water can collect in a line of drops at the
undersurface, producing a false rejection because of flashover or high leakage current.
5-4.12.4 Take overlapping readings from one end of the tool to the other but do not
slide the tester on the tool. Lift up the tester before moving it. This can prevent streaks
that can cause a false rejection.
5-4.12.5 Rotate the tool 90 degrees and again test the tool from end to end. Continue
in this manner until four different positions around the tool circumference have been
Transportation. Live-line tools must be transported with care and protected
from mechanical damage. Exposure to inclement weather must be avoided.
Containers must prevent damage to insulating surfaces from abrasive surfaces and
bumping motions, and to minimize contamination buildup. In house fabricated
containers made from PVC pipe and fittings provide excellent protection for live line
tools. Special PVC fittings are also available from vendors for this purpose.
Storage. All live-line tools not being regularly transported must be stored in a
dry location and must not be tampered with or handled by unauthorized personnel. If
possible avoid locations subject to temperature changes because this can permit the
formation of condensation and because wood tools can warp. Store tools in bins and
racks, constructed to prevent damage to insulating surfaces, away from dirt, moisture
and sunlight (and other sources of ultraviolet light). In house fabricated containers
made from PVC pipe and fittings provide excellent protection for live line tools. Special
PVC fittings are also available from vendors for this purpose.
Use of Live-Line Tools. When using live-line tools, workers must not place
their hands closer than is absolutely necessary to energized conductors or equipment or
to the metal parts of the tool, and in no case closer than the minimum working distances
specified in Table 3-1. Additional requirements on the use of live-line tools include:
5-4.15.1 If tools used have quick-change heads, they must not be used without a
"quick change safety clip".
5-4.15.2 Approved blocks, ropes, slings and other tackle used in live-line tool work
must not be used for any other purpose and must be kept clean, dry and free from
5-4.15.3 Live-line tools being used to spread or raise conductors must be securely
fastened and must not be held by workers except as necessary to secure or release
