Arc flash is a dangerous release of energy caused by an electrical arc. It produces intense heat, light, pressure, and sound that can cause severe burns, blindness, hearing loss, and fatal injuries.

Alpha Arc Flash is a company specializing in arc flash risk assessment, safety training, PPE selection, labeling, and mitigation services for industrial, commercial, and utility customers.

An assessment identifies hazards, calculates incident energy and arc flash boundary, informs PPE selection, helps meet regulatory requirements, reduces liability, and guides engineering solutions to lower risk.

We follow NFPA 70E for electrical safety in the workplace, IEEE 1584 for arc flash calculations, and applicable OSHA standards. We also consider local codes and utility requirements.

Site survey of electrical equipment and one-line drawings review

• Short-circuit and coordination studies

• Arc flash incident energy calculations and boundaries

• Equipment labeling and documentation

• Written report with mitigation recommendations

NFPA 70E recommends review whenever changes occur in the electrical system. Many customers update every 3–5 years as a best practice or sooner after modifications.

Duration depends on facility size and complexity. Small facilities: 1–3 days. Medium: 3–7 days. Large or multi-site programs: several weeks to months - which includes report preparation and labeling.

• Single-line electrical diagrams if accessible (used to verify device count and accurate feeder information.)

• Equipment nameplate data (unique name on every device)

• Protective device settings if accessible. (TCC curves)

• Access to all equipment for data collection and labeling.

Using SKM software, we calculate incident energy and arc flash boundary for each piece of equipment, determine required PPE categories or incident energy values, and produce durable, code-compliant labels with clear hazard information.

Labels are required by NFPA 70E and are strongly enforced by OSHA as part of employer obligations to protect employees. Labels also reduce liability and improve worker safety.

PPE depends on calculated incident energy or NFPA 70E arc flash PPE categories. Typical PPE includes arc-rated clothing, face shields, balaclavas, gloves, insulating tools, and hearing protection. We specify exact levels per location.
