Even though a process computer system is designed with the best technology, the safety of the system can be compromised in its installation, operation, and management. For this reason, process computer audits should be performed. This paper concentrates on the items a process computer auditor should inspect when performing an audit. The areas included in the audit are fire protection, the environment, electrical power, ergonomics, fail-safety, alarms, safety interlock systems, security, design change control, contingency plans, maintenance, training, operations, and documentation. © 1993.
