Web the word is actually an acronym that stands for minimum approach distance, which is the calculated safe working distance that provides worker protection when working on or in the vicinity of energized lines and equipment. Web minimum approach distances for the voltage ranges are provided in column a. The approach distance for each work zone (see figures 3 and 4) will vary depending on the voltage of the overhead electric line and the level of authorisation of each person carrying out the work. * for nominal voltages not listed use the next higher voltage in the table. Web hand tools, hand control lines, equipment or other material held. Web for example, if the conductors are energized at 13.2 kv phase to phase, the minimum approach distance is 2 feet 3 inches and the worker’s arm reach is 3 feet, the worker must position their body 5 feet 3 inches from the energized conductor or device until they have donned rated rubber gloves.
