Arc Flash Hazard Analysis (IEEE 1584-2018)

Arc flash incidents can cause severe injury or death to electrical workers. Pythian Design provides comprehensive IEEE 1584-2018 compliant arc flash studies that identify hazards, determine required PPE, and produce ready-to-install warning labels. Our fast turnaround helps you maintain OSHA/NFPA 70E compliance and protect your workforce.

Why Arc Flash Studies Are Required

Worker Safety: Arc flash studies determine incident energy levels and specify required personal protective equipment (PPE).

OSHA/NFPA 70E Compliance: OSHA requires arc flash risk assessments. NFPA 70E is the standard for electrical safety in the workplace.

Equipment Labeling: NEC 110.16 requires arc flash warning labels on electrical equipment.

Liability Protection: Demonstrates due diligence in protecting workers from electrical hazards.

Insurance Requirements: Many insurers require current arc flash studies (updated within 5 years).

IEEE 1584-2018 vs. 2002 Edition

The 2018 edition incorporates new empirical test data and revised calculation methods.

New equations for intermediate voltage ranges (208V to 15kV) provide more accurate results.

Different calculation approaches for various equipment configurations and electrode orientations.

Expanded voltage ranges and better treatment of low-voltage systems.

We use the latest 2018 methodology for all studies, ensuring current code compliance.
