Arc Flash Protection
What is an Arc Flash?
Arc Flash protection is often overlooked.
An Arc Flash is 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. Arc Flash can result from many factors,
including dropped tools, accidental contact with electrical systems,
build up of conductive dust, corrosion, and improper work procedures.
It is important to have proper Arc Flash protection.
Why do I need to do an Arc Flash Hazard 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 Arc Flash Hazard 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:
-
Arc Flash
Hazard Analysis on All Electrical Exposure Areas
-
PPE
Determination based on potential energy exposure levels (cal/cm2)
-
Labeling of
each electrical source for its specific Arc Flash Hazard
Level
-
Delineating
the Arc Flash Hazard Areas
-
Training of
All Authorized Employees for Arc Flash
