    4. Objective Consequence and Risk Tolerance Criteria
    5. Corporate Process Safety Management Systems
  3. Process Hazard Identification Techniques
    1. Risk Identification and Assessment (HAZID)
      •  Performed:
          − At an early stage in the process design
          − Prior to major modification to process
          − During development or modification of operating procedures (e.g. start-up, shut-down, other transient conditions)
      •  Looks for major hazards associated with
          − Process materials
          − Releases
          − Equipment failures
      •  Consider past history, present operation, future conditions
      •  Define Boundary for study and assess
      •  Systematically record and assess
    2. Introduction to Process Hazard Analysis (PHA)
      •  More detailed studies of individual sections of the process
          − What-If (Outline)
          − Checklist (Outline)
          − What-If/Checklist (Outline)
          − FEMA (Outline)
          − HAZOP (Detailed)
          − LOPA (Outline)
          − Fault Tree (Outline)
          − QRA (Outline)
  4. Audits
    •  Purpose
    •  Basis
    •  Written report
    •  Required response
    •  Follow-up audit
    •  Audits repeated at regular specified intervals
  5. Incident Investigation
    •  Incident classification
    •  Avoid conflict of interest in team make-up
    •  Construct a time-line
    •  Interview all personnel with any involvement in incident
    •  Determine root cause(s) NOT immediate causes – Root causes are reason(s) why the immediate causes occurred
    •  Write report
    •  Require written responses.
    •  Maintain library of all incident reports.
  6. Examples and Problems
