Process Hazard Analysis

Process Hazard Analysis

Process Hazard Analysis is a systematic and structured approach used to identify, evaluate, and control process-related hazards throughout the lifecycle of a facility. PHA ensures that potential causes of fires, explosions, toxic releases, runaway reactions, equipment failures, and operational deviations are identified early — and appropriate safeguards are defined, verified, and improved.

Why Conduct PHA?

  • Meet regulatory requirements (OSHA PSM, EPA RMP)
  • Reduce process safety incidents and operational downtime
  • Improve safety culture and risk visibility for management and operators
  • Strengthening engineering and design decision-making
  • Prioritize investments where risk-reduction impact is highest
  • Industries Served:

  • Our team supports a wide cross-section of industrial and emerging energy sectors:
  • Chemical + Petrochemical
  • Refining and Hydrogen production
  • Battery manufacturing + Energy storage
  • Specialty chemicals + Pharma
  • R&D labs and pilot plants
  • Our PHA Methodologies:

    • Our team supports a wide

      We offer multiple PHA study formats depending on system complexity, maturity, and regulatory needs:

      1. HAZOP (Hazard and Operability Study)

      Ideal for complex continuous and batch chemical processes.

       

      1. LOPA (Layer of Protection Analysis)

      Semi-quantitative evaluation of safeguards and risk reduction requirements.

       

      1. Hazard Identification & Risk Assessment (HIRA)

      A systematic approach for identifying workplace and process hazards, assessing likelihood and consequence, and prioritizing mitigation measures.

       

      1. Root Cause Analysis (RCA)

      A structured investigation process used to identify the underlying technical, human, or organizational factors contributing to incidents or near-misses.

       

      1. Quantitative Risk Assessment (QRA)

      Detailed numerical evaluation of accident frequencies and potential consequences

       

      1. Consequence Modeling

      Predictive modeling of fire, explosion, or toxic release scenarios using advanced simulation tools to understand potential impacts on people, equipment, and the environment.

      We also provide PHA revalidations, PHA project management, and PHA gap reviews for sites seeking second-party validation.

    OSHA PSM requires PHA revalidation at least every 5 years. However, many facilities conduct internal reviews more frequently.
    Yes. We often align PHA outcomes with relief system design, flare network analysis, and chemical reactivity testing for a comprehensive safety evaluation.
    Yes. Performing PHAs during R&D and pilot phases helps identify early hazards and supports safe scale-up.
