Back to the Basics: Operator Training & Visibility of Alarms
Regardless of the amount of automation in the process, it is critical to train all personnel, including operators and maintenance workers, on the exact meaning of the analyzer readings and alarms.
Following any shut-down, the process should not re-start until the alarms have been manually reset and cleared, and the cause of the alarm understood and corrected.
The alarm and reading of the analyzer should also be easily and quickly visible by the operator, so that prompt and clear actions can be taken in response to a dangerous condition.
