Critical Process Safety Guideline
Risk of Personal Injury
When this instrument is being used in a critical process that could cause property
damage and personal injury, the user should provide redundant device or system that
will initiate a safe process shutdown in the event that this instrument should fail.
The user should provide a redundant system or device that will initiate a safe process shutdown in
the event that this instrument or associated system should fail. The control of a process should not
be solely dependent upon this instrument and its peripheral components. Other measuring and
controlling safe-guards should be included in a redundant system designed to provide warning of
conditions that may cause personal injury or property damage. These safeguards should be in place
at all times, including startup and shutdown, as well as normal operation.
Procedures should be in place that verifies proper instrument and system operation after service,
maintenance or replacement to insure the instrument and peripheral components are returned to service
properly. All alignments, settings and connections required for proper operation must be performed or
verified.
A computer with specialized software may be used as an operator interface for setup and operation of
the system. Digital and analog communication with alarms and controllers may be part of the system
making it a more complex system. Changing software configurations and settings requires that process
performance be verified.
