Why Poor alarm management

has been identified as a

contributing factor is many

major process incidents.

An ISA 18.2 global alarm philosophy

applied retroactively as far as reasonably

practical to reflect best corporate &

industry practices.

We are stuck with technology, when what we really wanted

was something that worked. Douglas Adams

� An alarm is an audible and/or visible means of indicating � There must be an indication of the alarm. An alarm limit can be configured to

generate control actions or log data but if this limit is not audibly or visually indicated it should not be considered an alarm.

� to the operator� The indication must be targeted to the operator to be an alarm, not to provide

information to an engineer, maintenance technician, or manager.

� an equipment malfunction, process deviation, or abnormal condition� The alarm must indicate a problem or unexpected situation, not a normal

process condition or expected operational event (e.g., pump stopped, valve closed).

� requiring a response� There must be a defined operator response to correct the abnormal condition

and bring the process back to a desired (safe and/or productive) state. If the operator does not need to perform a corrective action, such as opening a valve or starting a pump, then the condition should not be an alarm. Acknowledging the alarm or logging a measurement is not considered an operator response since it does not correct the abnormal situation.

There are more things to alarm us than to harm us, and we suffer more often in

apprehension than reality. Lucius Annaeus Seneca

someone flattened by
