Process Hazard Analysis (PHA)

Process Hazard Analysis (PHA)

A process hazard analysis is an organized and systematic assessment of the potential hazards associated with an industrial process. Having a complete and up-to-date process hazard analysis is a legal requirement for many operating facilities per OSHA 29 CFR 1910.119 and EPA 40 CFR 68.67. In addition to the initial PHA, OSHA and EPA require a PHA revalidation every five years. Many operators that do not meet the criteria requiring a PHA will elect to complete a design hazard review of their facilities, recognizing the safety and operability benefits for all processes.

Inglenook Engineering is trained in several of the hazard analysis methods used to complete a process or design hazard review:

  • What-if/Checklist
  • Hazard-identification (HAZID)
  • Hazard and operability review (HAZOP)
  • Layer of protection analysis (LOPA)

Additionally, Inglenook has a wealth of project experience involving the other process safety management (PSM) elements outlined in the OSHA PSM standard.

This experience allows Inglenook to help an organization in several ways:

  • Identify process areas that may benefit from or are required to have a formal hazard review
  • Assist in developing a cross-functional team to participate in the hazard review
  • Assist in selecting the appropriate method based on project stage and goals
  • Identify key process nodes and define relevant deviations for each node
  • Facilitate the hazard review using a schedule that works for the project team
  • Compile the hazard review report and review it with management before finalizing
  • Develop practical design solutions to the identified findings that fall within Inglenook’s area of expertise (See PHA Concern Follow Up and Resolution)
