Which procedural measure is essential during operational controls for plant startup?

Use of outdated procedures
Intelligent alarms in control systems
Minimal supervision
Traditional manual checks

The correct answer is: Intelligent alarms in control systems

The use of intelligent alarms in control systems is essential during operational controls for plant startup because these alarms enhance safety and efficiency in the operational environment. Intelligent alarms are designed to monitor various parameters and detect anomalies in real-time, providing operators with timely alerts that can prevent potential incidents or equipment failures. During the startup phase of a plant, there are numerous variables that need to be controlled and monitored to ensure safe operations. Intelligent alarm systems help in flagging abnormal conditions, allowing for quick responses to issues before they escalate into serious problems. This contributes significantly to maintaining safe operational conditions, protecting both personnel and equipment. In contrast, relying on outdated procedures could lead to missed risks, minimal supervision can result in undetected hazards, and traditional manual checks, while useful, may not offer the same level of real-time monitoring and responsiveness as intelligent alarms. Therefore, utilizing advanced alarm systems is crucial for effective operational control in any plant startup scenario.
