We Stay Within Operating Limits

One of the ten Process Safety Fundamentals

Equipment operated with process conditions (e.g., temperature, pressure, level, flowrate) outside of safe operating limits (high or low) can result in unstable and unpredictable operation and the potential for process safety incidents. It is therefore important to understand the operating limits of the plant and stay within that operating envelope. It is useful for teams to discuss how these limits are documented at their site and whether the limits are clear and available.

🔺 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.
