The safety culture in the electric utility industry is evolving at
an accelerated pace due to advancements in technology and
the desire for every worker to go home safe every day. This
series of tests was conducted as part of a safety initiative, to
ensure that utility linemen and other electrical workers are
protected at lower voltages. This investigation demonstrated
conclusively that 120-volt and 240-volt arcs are not able to
sustain themselves and self extinguish very quickly in a utility
lineman’s normal low-voltage working environment, greatly
minimizing the resulting incident energy and its effect on the
worker.
