Alarm Management

Optimising alarm system design is important to facilitate accurate and timely fault prompting and diagnosis to operators, and hence more effective plant management. Alarm systems should accommodate human capabilities and limitations:

  • Alarms should direct the operator’s attention towards plant conditions requiring timely assessment or action;
  • Alarms should alert, inform and guide required operator action;
  • Every alarm should be useful and relevant to the operator, and have a defined response;
  • Alarm levels should be set such that the operators have sufficient time to carry out their defined response before the plant condition escalates.
