Because of the explosive nature of equipment failures, serious burn injuries
in the electrical industry are of great concern. Detailed investigation into
arc flash incidents has led the National Fire Protection Association (NFPA)
to adopt arc flash guidelines (NFPA-70E) for work on or near energized
electrical equipment. Arc flash studies help ensure employee safety against
dangers associated with the release of energy caused by an electrical arc,
ensure compliance with industry safety standards, and provide required
device labeling to communicate proper levels of Personal Protective
Equipment (PPE) and safe approach/working distances.
EN Consulting, a sector of ENTRUST Solutions Group, has extensive experience
in arc flash analysis within industrial, utility generation, and commercial
environments, including refineries, heavy and light oil terminals, utility
generation facilities, recreational buildings, convenient stores, large
production facilities, and chemical production facilities. Our highly
qualified and licensed professional engineers provide technically compliant
arc flash reports, arc flash equipment labels, electrical hazard training,
and arc flash mitigation services to help eliminate hazards.
As part of EN Consulting’s arc flash study, recommendations will be made to
mitigate arc flash hazards. Usually these are areas where the incident
energy exceeds 40 cal./cm2. Typical recommendations may include adjustment
of protective device settings, administrative controls, or the purchase of
remote breaker operating mechanisms. EN Consulting design professionals have
considerable experience implementing engineered solutions to mitigate arc
flash hazards, some of which include:
