Since 1990, there have been at least 75 fatal and 1,850 non-fatal accidents in the mining industry which were classified by MSHA as "Electrical." Many of these could have been prevented if the circuits would have been locked, grounded, and tagged prior to any maintenance work being performed. MSHA regulations for both Metal/Nonmetal and Coal require locking and tagging electrical circuits prior to working on circuits or the mechanical equipment supplied by the circuit. An additional step, the grounding of the circuit adds an important layer of protection for you in case someone may accidently remove your lock and restore power. This procedure is SIMPLE, QUICK, EFFECTIVE, and LIFE-SAVING. Don't forget to take these simple steps prior to performing any electrical work:
The video cassette, "Pathway to Safety" (VC-957), available from MSHA, shows you the effects of not taking the time to lock out. To get your copy of this video, please contact the Library at the National Mine Health and Safety Academy at (304) 256-3266 or MSHALibrary@dol.gov.
