Arc Flash Services

OSHA requires that all employers provide and establish a complete electrical safety program including this arc flash safety program. This includes labeling all required electrical panels in any non-residential facility with the ANSI approved arc flash warning labels. ITU is a nationwide provider of arc flash risk assessments and studies serving clients for over fifteen years. ITU has provided the arc flash study for the OSHA and NIOSH headquarters buildings in Washington DC.

Arc Flash Warning Labels

NEC (National Electrical Code) mandates that hazardous equipment installed or modified after 2002 be required to carry an arc flash warning label. NEC 110.16 specifically mentions “switchboards, panel boards, industrial control panels, and motor control centers that … are likely to require examination, adjustment, servicing, or maintenance while energized.”

NFPA 70E 2015 (National Fire Protection Agency) requires labels to contain the following information:

Nominal System Voltage, Arc Flash Boundary, and at least one of the following:

  • Available incident energy and the corresponding working distance, or the arc flash ppe in Table 130.7(C)(15)(A)(b) or Table 130.7(C)(15)(B) for the equipment, but not both
  • Minimum arc rating clothing
  • Site-specific level of PPE

These values are determined by an arc flash risk assessment (available through ITU), and need to be calculated separately for each piece of equipment labeled.
NFPA 70E also states that arc flash warning labels must be the proper size (at least 4”x 6” recommended to meet required font sizes), ANSI Z535 approved, and be placed so as to be visible to personnel before beginning maintenance or inspection.
