Arc Flash Hazard Analysis and Training
What is an Arc-Flash Hazard and why does my company need an analysis?
An Arc-Flash hazard is a condition created by an electrical arc being drawn into the open air between two conductive surfaces. The arc and resulting explosion can release a tremendous amount of energy (incident energy). Incident energy is real and is deadly. It is typically measured in Calories per Square Centimeter. An arc-flash hazard analysis is the determination of what that energy level is. Knowing the level of energy, it is possible to determine the correct procedures and personnel protective equipment (PPE) required to work near the electrical device. Finally, NFPA 70E is quickly becoming the law of the land. NFPA 70E requires an arc-flash hazard program.
What does the Arc Flash Hazard Analysis from AET do for me?
- Identify the amount of arc flash incident energy
- Identify the arc flash protection boundaries about electrical equipment
- Identify the correct personal protective equipment (PPE) required
- Identify minimum safe working distance
- Identify the limited, restricted, and prohibited approach boundaries
- AET will provide and install labels for each switchboard, transformer, motor control center, panelboard, cable tray, transfer switch, and capacitor bank.
- AET will, at your request, also provide training for your personnel in the proper selection of protective equipment based on the incident energy and other dangers identified on the labels.
OK, so we hire AET to provide the analysis, attached the labels, taken the training. Now what do I do with it?
Apply the safety training, wear personal protective equipment, and follow established operating and safety procedures.
