Avoiding Arc Flashes

Arc Flashes are one of the deadliest incidents when working with high voltage systems. Arc Flash temperatures can be as high as 35,000° Fahrenheit. Arc flash accidents can result in broken bones, collapsed lungs, permanent hearing damage, or instant deaths. Never underestimate the severity of any voltage and always follow all protective measures at your workplace. Every facility should have a plan to prevent arc flashes from happening if you feel unsafe or unsure; stop what you are doing immediately and talk with your supervisor.

How to Prevent Arc Flash and Safety That Should Be Maintained To Prevent Workplace Injury:

  • Keep All Equipment Well Maintained
  • Have Proper and Updated Flash Hazard Analysis Signs
  • Keep Your Work Area Clean
  • Have Proper Electrical PPE
    •    This is the last line of defense that can protect you from a serious injury. The proper PPE that should be worn is a face shield, helmet or headgear, flame-resistant clothing, safety glasses, insulating gloves, and shoes/boots that contain no metal. Ensure that employees are using  insulated tools.
  • Employers need to do a proper risk assessment and hazard analysis for the PPE requirements
  • All employees must be familiar with safety-related practices that involve their job assignments
  • A qualified person must use test equipment to test the circuit elements and electrical parts of the equipment to which the employees will be exposed to
  • Implement Lockout Tagout procedures
