An arc fl ash can be traced to di� erent things: equipment failure, corrosion, dust and poor installation. When workers are interacting with (e.g., testing, troubleshooting, switching) energized electrical equipment and accidentally drop tools or make contact with live parts, an arc fl ash can occur. Extensive burns, blindness, hearing loss and even death may result.

Hazards Involved/Arise Working with energized electrical equipment

Equipment that is not installed to meet applicable codes

Equipment that is not maintained properly

Poorly maintained or installed electrical equipment

People A� ected Qualifi ed workers (e.g., electricians)

Unqualifi ed workers (everyone else)

ARC FLASH

Existing Controls Do not work with energized equipment — zero energy state is preferred (locked out conditions)

Follow recognized standards (for example, CSA Z462) to support development and implementation of an electrical safety program

Select, use and properly care for the appropriate electrical Personal Protective Equipment (PPE)

Provide training for all a� ected personnel and electrical safety-related practices
