NFPA 70E

What is NFPA 70E?

An NFPA 70E a dangerous condition associated with the explosive release of energy caused by an electrical arc due to either a phase to ground or phase to phase fault. NFPA 70E can result from many factors, including dropped tools, accidental contact with electrical systems, build up of conductive dust, corrosion, and improper work procedures.

Why do I need to do an NFPA 70E Analysis?

Per NFPA 70E-2004, Part II 2-1.3.3 Arc Flash Hazard Analysis states that a "Flash hazard analysis shall be done before a person approaches any exposed electrical conductor or circuit part that has not been placed in an electrically safe work condition." These NFPA 70E Analysis calculations must be performed to determine the appropriate PPE required for personnel working near any exposed electrical conductor or circuit part. In order to determine the appropriate level of PPE required, the available fault current at the energized electrical equipment being serviced must be known for Arc Flash analysis.

NFPA 70E requires the following elements:

• NFPA 70E Analysis on All Electrical Exposure Areas

• PPE Determination based on potential energy exposure levels (cal/cm2)

• Labeling of each electrical source for its specific NFPA 70E
  Level

• Delineating the Arc Flash Hazard Areas

• Training of All Authorized Employees for NFPA 70E

• Other items as applicable
