105: Analysis Not Performed

Node Analysis Not Performed

Definition/Typical Issues

Was there a failure to perform a safety/hazard/risk review?

Typical analyses addressed by this node include:

  • Process hazard analyses
  • Hazard and operability analyses
  • Reliability analyses
  • Security vulnerability analyses
  • Failure modes and effects analyses
  • Reliability-centered maintenance analyses
  • Enterprise risk management analyses
  • Project risk management analyses
  • Fault tree analyses
  • Event tree analyses
  • Probabilistic risk assessments
  • Job safety analyses

Examples

Example 1

  • An explosion occurred in a waste tank after a new stream had been tied into the tank. No safety review had been performed prior to tying in the stream to determine whether incompatible materials would be in the waste tank after the tie in.

Example 2

  • No analysis had been performed to determine the operational risks associated with a new conveyor system. As a result, the line had to be redesigned after several failures.

Example 3

  • No job safety analysis was performed prior to disassembly of a pump involved in an incident. Acid had entered the pump during the incident, and the workers were exposed to it during the disassembly process. No job safety analysis had been performed because the disassembly used a standard procedure.

Example 4

  • A new composite material for which no applicable standard existed was employed as part of a ship hull structure. A risk assessment was not performed from which to determine the best means of integrating the material with otherwise conventional vessel structure.

Example 5

  • The process hazard analysis for a reactor was supposed to be updated every 5 years. However, it had not been updated as required. As a result, a significant hazard had not been identified.

Example 6

  • No security analysis for the facility had been performed, even though regulations and company policy required the analysis to be performed.

Typical Recommendations

  • Provide a safety/hazard/risk review procedure that complies with all applicable orders, regulations, and guides.
  • Ensure that the hazard review procedure is readily available to personnel who will conduct the review.
  • Periodically audit hazard review meetings and reports.
  • Establish minimum training criteria for hazard review leaders.
  • Review hazardous operations to ensure that hazard assessments have been performed.
  • Develop a list of equipment and the corresponding job safety analyses (JSAs). Develop JSAs for any equipment that needs one.
  • Perform field audits of personnel activities to determine which activities require JSAs.
  • Determine when risk analyses should be performed:
    • Laboratory-scale development
    • Pilot-scale or semiworks operations
    • Conceptual design
    • Before selecting a plant site
    • Before ordering long-lead equipment
    • Detailed design
    • Before construction
    • Before startup
    • During operation
    • Before shutdown
    • Before demolition
  • Develop a schedule for performing proactive risk assessments.
  • Specify when proactive analyses need to be revalidated.
  • Assign the task of performing proactive analyses to specific personnel.
  • Develop a list of units and activities that must have proactive analyses performed.
  • Train workers on how to recognize hazards and how to recognize when unknown hazards may be present.
