The 4P Methodology for Electric Arc Flash Hazard Assessment
INCLUDING THERMAL EFFECT SEVERITY PREDICTION
By taking a holistic approach to arc flash risk and protection, the 4P Methodology simplifies hazard assessment to four steps:
- Predict severity of arc flash
- Prevent damage through hazard mitigation
- Protect workers from residual hazard
- Publish results
With hazard mitigation - and risk reduction - implemented, any residual risk of injury to individuals can be mitigated with PPE. Finally, the results can be published to inform behaviour and guide PPE usage.
