Risk-Based Dust Hazard Analysis

Expo A1

Speaker: Fuman Zhao, Senior Process Safety Engineer, PSRG

Combustible dust explosions have caused numerous fatalities. They are now a recognized hazard that plant owners and workers cannot ignore. Many industry-specific NFPA dust standards contain provisions for dust PHAs. The newest standard NFPA 652 requires that dust hazards analysis (DHA) be completed on existing facilities and significant modifications. However, NFPA performance-based dust hazard assessment and OSHA compliance requirements lack detailed guidance on how to conduct DHA. Standard-based prescriptive DHA may create unnecessary overprotection. This presentation will explore a risk-based approach developed by incorporating both likelihood and consequence analysis to define safeguard requirements. By comparing safeguard requirements with the credit provided through safeguard availability analysis, a risk-based DHA will provide a sufficient understanding of dust hazards, as well as the safeguard level of demand for dust process safety work activity.
