Controlling Arc-Flash Hazards Using Electrical Engineering Controls

The most effective ways to protect electrical workers from electrical arcs or blasts includes reducing Incident Energy (IE) levels to acceptable levels and/or to physically separate electrical workers from electrical arc exposures. This is accomplished via Electrical Engineering techniques including Arc Flash Risk Assessments, also known as Arc Flash Hazard Analysis.

Although we have performed Arc Flash studies on many commercial/industrial faclities, Praxis has unusual skills in performing AFHA on "Renewable Power" facilities such as wind farms and solar farms. Wind farms and Solar farms include both Low Voltage and High Voltage systems, and our ability to address both types of systems is invaluable here. Praxis Electrical Engineers are all Journeymen Linemen or Master Electricians and we integrate our practical knowledge into our AFHA studies to maximize the utility of any Arc Flash study we provide. We also provide follow-on training regarding how to USE the AFHA study for managers and for Electrical Workers.

Arc-Flash Risk Assessment (a.k.a. Arc Flash Hazard Analysis)
The NFPA 70E-2015 requires employers to perform an Arc Flash Risk Assessment to determine the electrical burn potential for employees who perform electrical work. Arc Flash analysis requires a system of sub-processes including:

• Validation of System Schematics
• Short Circuit Studies
• Coordination Studies 
• Flash Hazard Analysis
• Equipment Labeling
• Employee Training 

The NFPA 70E requires that AFHA studies must be reviewed every 5 years. Contact Praxis if your study is due for review.
