Electricity has killed three people in the industry since August 7, 2019.
- An electrician contacted an energized component of a 4,160 VAC electrical circuit while adjusting the linkage between the disconnect lever and the internal components of the panel that supplied power to the plant feed belt motors.
- A contract electrician contacted an energized 120 VAC conductor while working inside a fire suppression system’s electrical panel.
- An electrician contacted an exposed energized connector while troubleshooting a 995 VAC flooded bed scrubber motor circuit on-board a continuous mining machine.
Prevent Electrical Accidents:
- Lockout/Tagout circuits before working on electrical equipment.
- Don’t rush. Never work alone. Talk to coworkers and confirm your plan is safe.
- Identify and control all hazardous energy sources before conducting any task and follow safe work procedures.
- Open the circuit breaker or load break switch to de-energize the incoming power cables or conductors
- Open the visual disconnect to confirm incoming power is off
- Lockout/Tagout the visual disconnect
- Ground the de-energized conductors
- Electricians must know how to de-energize and disconnect electrical systems and equipment.
- Always troubleshoot without power first.
- If you must troubleshoot an energized circuit, use properly rated personal protective equipment to prevent hazards. For example, use electrically rated gloves, insulated blankets or mats, and poly-carbonate barriers to prevent accidental contact with energized components.
