Arc Flash Risk Assessments

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. 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.

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, Arc Flash Hazard Assessment, or Arc Flash Study), Lewellyn can provide you with a comprehensive, customized safety solution for your facility.

Our Process

What makes Lewellyn’s Arc Flash Risk Assessment process unique? Our people. Data-driven, in-house engineers and full-time field technicians that are dedicated to providing the highest level of service. From the initial site visit, through final infrastructure labelling and our practical electrical safety training programs, our Arc Flash team of consultants, engineers, and field technicians are focused on more than just compliance – we deliver comprehensive safety programs suited to the unique challenges of your facility.

Our Arc Flash Risk Assessment process includes:

Data Collection: our experts perform an exhaustive review of all facility electrical distribution systems.

Single-Line Model: fueled by data, we create a complete model of your electrical distribution system.

Engineering Analysis: using the system model, our team completes and reports on multiple engineering analyses including: a Short Circuit Analysis, Protective Device Coordination Analysis, Protective Device Interrupt Rating Analysis, and an Incident Energy Analysis.

Report of Findings: a highlight of all risks within your system (compared to NFPA 70E criteria), delivered and presented to key stakeholders by a Lewellyn expert.

Field Labelling: data-based labels are printed and installed throughout your facility on your electrical equipment by our field technicians.

Electrical Safe Work Practices Training: practical, hands-on training tailored to your workplace and employees, conducted by our experienced, industry-savvy trainers.
