The underground environment is hard on equipment and especially electrical cables that feed the power to mechanized bolter and Jumbo drills. These cables are run out of the machines and hung on dielectric hooks on a daily basis in order to install ground support or to drill off a round.
The proper way to complete this task is to run the cable out as the machine is brought into the heading upon set up. Once the machine is place, pick up the cable and hang it on dielectric hooks all the way back to the power source. Once this has been completed the cable then can be connected to the power source. No power in the cable no risk to the employee handling the cable.
When someone tries to hurry up the task and remove one of these steps they raise the risk to themselves for an electrical injury or the ultimate sacrifice their lives. These cables due to the nature of there usage can receive small cuts or damage that can go unnoticed. If you handle or touch this cable once it has been energized you run the risk of electrical mishap. Remember a dead electrical runs no risk to the employee. Touching an energized electrical cable runs a high risk of injury or death to the employee. When comes to coupling and uncoupling training cables from a machine there is only one way to do it safely and that is to only handle de-energized cables.
