In a startup sequence, which option lists the correct order?

• A. Verify SOP, start controls, perform pre-start checks, monitor alarms.
• B. Start controls, verify SOP, perform pre-start checks, monitor alarms.
• C. Verify SOP, ensure safety interlocks are active, perform pre-start checks, start controls, monitor for alarms.
• D. Monitor alarms, then start controls.

Answer: (C)

In a startup sequence, safety and readiness hinge on doing things in a proper order. First, verify the standard operating procedure so you’re following the current steps and safety rules. Next, ensure that safety interlocks are active, so protective systems are in place before any equipment is energized. Then perform pre-start checks to confirm that equipment, sensors, and control systems are ready and within specification. Only after these steps should you start the controls to bring the system online. Finally, monitor for alarms to catch any faults as the system comes up and continues to operate. This order ensures safeguards are active and the system is genuinely ready before any activation, reducing the risk of faults or accidents. Skipping verification, neglecting interlocks, or skipping pre-start checks can lead to unsafe startups or missed issues, which is why the described sequence is the correct one.
