Question of the Week
  • How often should a revalidation PHA be conducted?

Question: How often should a revalidation PHA be conducted?

Answer:

OSHA's PSM standard states: "At least every five (5) years after the completion of the initial PHA, the PHA shall be updated and revalidated by a team meeting the requirements in paragraph (e)(4) of this section, to assure that the PHA is consistent with the current process."

However, a periodic PHA revalidation may need to be performed more frequently for any of the following reasons:

  • Cumulative number of changes
  • Major changes
  • Significant incidents or an unfavorable trend
  • Knowledge of significant omissions and deficiencies
  • Concern about the quality of the previous PHA
  • High risk processes
  • Reconciliation of PHA approaches after mergers / acquisitions
