WIRE OBSTACLESD-10. A wire obstacle is a wire or set of wires (regardless of height or type) located within 1000 meters of any edge of the surveyed or tactically assessed DZ. The types of wire obstacles that could pose a risk to jumpers are electric, telephone, or cable television wires. Wire fence can be regarded as an obstacle if it poses a hazard to jumpers. Power line capacity (voltage or amperage) is not a factor when determining the risk to jumpers who may come in contact with a wire obstacle on or near the DZ.CAUTIONRegardless of voltage or current carrying capacity, if a power line is located within 1000 meters of any edge of the surveyed or tactically assessed DZ, the power should be cut off before using the DZ, if possible.
