Working with Electricity at a Mine
Working with or around electricity can expose miners and others onsite to a range of hazards, including electric shock, arc flash, and even explosions and toxic chemicals when working with batteries. This course discusses the elements of an effective electrical safety program, testing electrical circuits, using extension cords, working with batteries and generators, and how to work safely around power lines. Based on MSHA’s Title 30 CFR Part 46.5.b.4.

Sample Video Transcript
Working with large automotive and marine batteries can expose minors and others on sight to toxic chemicals, electric shock, arc flash, and potential explosions. Minors tasked with charging, installing, removing, or maintaining batteries should be properly trained to safely perform those tasks. In extreme cases, batteries can overheat and cause a fire or even explode. When this happens, the battery can release battery acid, lead, and toxic fumes, potentially injuring skin, eyes, and lungs. When batteries are charging, explosive gases such as hydrogen are produced, creating an increased fire hazard. Operating batteries in dirty, dusty environments can also cause problems. Surface leakage, created by accumulated dust mixing with spilled electrolyte, can cause the battery to short and create a fire hazard.
