This is an extract of the supporting information & guidance cards from the IOGP Process Safety Fundamentals documented in their Report 638.

  • We discuss and use the approved operating limits for our location.
  • We escalate where we cannot work within operating limits.
  • We alert supervision if an alarm response action is unclear or the time to respond is inadequate.
  • We obtain formal approval before changing operating limits.
  • We confirm that potential for overpressure from temporary pressure sources has been addressed.

Tips for Managers:

  • Establish and document safe operating limits for key process variables and make them visible to front-line workers.
  • Regularly check that personnel have the necessary skills and knowledge to stay within operating limits.
  • Systematically investigate excursions outside operating limits.
  • Demonstrate through decisions that cost, production or schedule does not override safety

This page only summarises the guidance – refer to the IOGP report and/or IOGP website for further information.
