Alarm Management & Rationalization
An alarm system is one of the tools to support the operator to ensure safe and efficient plant operation, thus the alarm system shall be designed within a framework of considering the complete operator role and support system.
In order to design each alarm, the following issues shall be addressed:
a. The purpose of the alarm.
b. Risk assessment of the alarm to identify all alarms which are required to support the safety of the production unit.
c. The priority of the alarm.
d. The response required from the operator to the alarm
e. The likely consequences if the operator does not respond to the alarm.
f. The time available for the operator to respond to the alarm.
g. The effectiveness of the operator response.
Alarm Rationalization
The primary purpose of prioritisation is to make it easier for the operator to identify important alarms when a number of alarms occur together. The prioritisation of an alarm shall be based on the severity of the consequences that the operator could prevent by responding appropriately to it with corrective action and the time available, compared with the time required for the corrective action to be performed and to have the desired effect.
Prioritisation shall take into consideration that the severity of consequences and the time available to respond may depend on the state of the production unit.
