Dangerous Incident: Electric Shock Protocols Enacted during Weekly Checks

March 29, 2018 Tara


An electrician was conducting weekly tests on a continuous miner in the maingate underground. When the electrician touched the lead connected to the continuous miner while connecting it to the remote (to function test the continuous miner) they reported feeling a tingle in their hand.  Workers then isolated power to the continuous miner and barricaded the area to preserve the scene. The electrician was taken to the surface and site electric shock protocols were enacted.

Recommendations to Industry:

Mines should confirm all enclosures onboard mobile equipment are correctly earthed, and plug/sockets have the correct ingress protection (IP) rating and are maintained in a fit-for-purpose state.
