This practical, operations-focused course provides the hands-on skills necessary for control room staff to proficiently **navigate, operate, and respond to alarms** within a typical SCADA environment. The focus is on executing routine control actions, monitoring process variables, and managing the alarm queue effectively to maintain process stability. Participants will be trained on techniques for maintaining situational awareness and following structured response procedures to safely manage abnormal conditions. Mastering these fundamental operational skills is crucial for minimizing downtime and ensuring continuous service delivery in critical infrastructure.
