Arc Flash NFPA 70E & IEEE 1584 Studies
An arc flash hazard analysis is an electrical engineering study to:
- Determine the risk of personnel injury as a result of exposure to incident energy (IE) released during an arc-flash event.
- Provide recommendations for appropriate arc-flash hazard protection.
- Inform the personnel about the existing arc electrical safety.
- Comply with OSHA, NEC, and NFPA 70E requirements.
Based on the results of an arc-flash hazard analysis, the rating of personal protective equipment (PPE) such as gloves, flame-retardant shirts and pants, eye protection, etc can be properly selected for adequate personnel protection. Arc flash labels with this information will be provided as a part of this study.
ARC FLASH STUDY STEPS
Seven major steps involved in an electric arc flash hazard Study:
According to IEEE-1584, they include:
- Data Gathering.
- Power System Modeling.
- Short Circuit Analysis.
- Over current Protective Device Coordination.
- Arc Flash Study.
- Reports.
- Label Installation.
