A 44-year-old contract electrician was electrocuted after contacting a 120V cable while working inside a fire suppression system’s electrical panel, says the Mine Safety & Health Administration (MSHA).
Best Practices:
- Ensure miners receive proper training on all electrical related tasks.
- Ensure that circuit breakers and switches are properly labeled.
- Properly lock-out and tag-out electrical circuits prior to working on them.
- Wear properly rated and well maintained personal protective equipment while troubleshooting or testing energized circuits.
- Use properly insulated tools when performing electrical work.
- Use properly rated electrical meters and non-contact voltage testers to ensure electrical circuits have been de-energised prior to performing electrical work.
