ARC FLASH RISK ASSESSMENTS / ARC FLASH HAZARD ANALYSIS
OSHA requires employers to protect employees from electrical hazards, including arc flash. Yet OSHA does not specifically explain how to comply with these regulations. NFPA 70E is the bridge between OSHA regulations and compliance. It is the consensus standard for electrical safety in the workplace, referred to by OSHA on numerous occasions.
NFPA 70E 2018 states that safe work practices need to be used to protect employees from injuries while they are exposed to electrical hazards. An Arc Flash Risk Assessment is a detailed and comprehensive assessment that helps identify the potential hazards that a company has in its electrical system.
Can you be cited by OSHA for failing to comply with NFPA 70E? In short, yes. As a leader in NFPA 70E compliance and Arc Flash Risk Assessments (also known as Arc Flash Hazard Analysis, Incident Energy Analysis, or Arc Flash Study), Lewellyn can provide you with a comprehensive, customized arc flash safety solution for your facility.
Lewellyn’s arc flash risk assessment results include a set of actionable recommendations to implement risk controls according to the hierarchy of control methods (elimination, substitution, engineering controls, awareness, administrative controls, and PPE).
Our Arc Flash Risk Assessment includes 3 phases:
- PHASE I – Data Collection
Lewellyn’s field technicians will collect the necessary electrical data to perform an Arc Flash Hazard Analysis. We will gather data on all equipment necessary per IEEE 1584, including wire size, wire length, transformer data, circuit over-current protection information, among other data. The electrical distribution system will be analyzed from the utility connection point to the equipment in the facility.
- PHASE II – Engineering Analysis
The data collected in Phase I will be used to build a Single-Line Model (or One-Line Model) of the facility’s electrical distribution system. The model will be used to complete the Engineering Analysis, which includes a Short Circuit Analysis, Protective Device Coordination Analysis, Protective Device Interrupt Rating Analysis, and Incident Energy Analysis.
- PHASE III – Delivery and Labeling
The Engineering Analysis results are documented and reported to the facility. A presentation meeting will be held with facility representatives to discuss findings and actionable recommendations. Labels are printed and installed throughout the facility by a field technician.

What is an Arc Flash?
An Arc Flash is an explosive release of energy caused by an electrical arc due to either a phase to ground or phase to phase fault. This fault can be caused by many different incidents, including accidental contact with electrical systems, build up of conductive dust, corrosion, dropped tools, and improper work procedures. An arc flash can produce some of the hottest temperatures known to occur on earth – up to 35,000 degrees Fahrenheit. In comparison, the surface of the sun is only 9,000 degrees Fahrenheit. Not surprisingly, the risk of serious and fatal injury from these incidents is severe.
