MSHA Reports 26th Fatality

The Mine Safety and Health Administration (MSHA) reported that on Nov. 23, a miner was electrocuted while troubleshooting a disconnect box for the classifier drive motor. The victim had the electrical disconnect box open and the main power supply was not de-energized.

This is the 26th fatality reported in 2020, and the second classified as “Electrical.”

MSHA recommends the following best practices to avoid this type of accident:

  • Ensure electrical circuit components are properly designed and installed by qualified electrical personnel.
  • Ensure electrical troubleshooting and work are performed by people with proper electrical qualifications. Positively identify the circuit on which work will be conducted.
  • Before performing electrical work, locate the visual disconnect away from an enclosure and open it, lock it, and tag it, to ensure all electrical components in the enclosure are de-energized. Verify by testing for voltage using properly rated test equipment.
  • Wear properly rated and well maintained personal protective equipment, including arc flash protection such as a hood, gloves, shirt and pants.
  • Train miners on safe work practices for electrical equipment and circuits.
