Operations & Maintenance in Operating Integrity

Work within the barriers

What sits here

Plant is operated inside its safe operating envelope, and work is controlled so that barriers are not bypassed, defeated or overloaded. When a barrier is overridden, the override is authorised and controlled. When prevention fails, emergency response mitigates the consequences.
