Electrical Incident Investigations
Investigations Overview
Arc flash and electrical incident investigations may be performed in cases of litigation or following arc flash or electric shock accidents. An expert witness can provide insight into technical aspects of cases and can be retained by either side to assist in litigation. Technical understanding may be communicated regarding standards and compliance, common practice, or in rare cases, product failures which are typically due to improper hazard assessments or care and maintenance.
Even if litigation is not involved, using an electrical safety expert with extensive experience can provide insight into the real causes and lead toward effective and efficient solutions to prevent future incidents or lessen injury.
