Security management
Published in Michael L. Madigan, First Responders Handbook, 2017
Alarm management is usually necessary in a process manufacturing environment that is controlled by an operator using a control system, such as a DCS or a programmable logic controller (PLC). Such a system may have hundreds of individual alarms that up until very recently have probably been designed with only limited consideration of other alarms in the system. Since humans can only do one thing at a time and can pay attention to a limited number of things at a time, there needs to be a way to ensure that alarms are presented at a rate that can be assimilated by a human operator, particularly when the plant is upset or in an unusual condition. Alarms also need to be capable of directing the operator’s attention to the most important problem that he or she needs to act upon, using a priority to indicate degree of importance or rank, for instance.

So, the ultimate goal of the alarm management system is to sort out the priority alarms which are more important for smooth running of the process by discarding unnecessary and less important alarms. Thus, it helps to reduce the alarm monitoring load for the operators such that they can concentrate more toward effective and smooth running of the plant or process.

Alarm management helps the operators to identify abnormal events. There needs to be a procedure to deal with an avalanche of alarms by effectively suppressing secondary (nuisance) alarms and focusing on the primary (root) alarms.

Alarm management techniques offer significant and essential features for safe and efficient operation of the modern industry. Most of the today’s industrial alarm management systems suffer from poor efficiency especially in case of overloading. However, the role alarm system is vital to the safe and efficient running of the industry.
