Stop using operator error as an excuse. Apply human factors considerations to improve your alarm system and help operators respond to alarms effectively.
Alarms play a significant role in maintaining plant safety by notifying operators of an equipment malfunction, process deviation, or abnormal conditions that requires a timely response . Alarms are one of the first layers of protection for preventing a hazard from escalating to an incident or accident. They work in conjunction with other independent protection layers (IPLs) such as relief valves, dikes, and safety instrumented systems (SIS).
