Action for GT leakage:

Action for GT leakage:

• A. Secure immediately
• B. Secure at earliest opportunity
• C. Do nothing
• D. Lockout and quarantine

Answer: (B)

When a GT (gas turbine) leakage is detected, the priority is to reduce the hazard as quickly as safely possible by bringing the system to a controlled safe state. Securing the turbine at the earliest opportunity accomplishes this: it minimizes fuel flow, depressurizes the system, and isolates the potentially leaking area before the risk of ignition or escalation grows. Acting too quickly without following proper safety steps can misfire procedures or put personnel at risk, while delaying too long leaves more fuel and pressure in the line, increasing danger. Doing nothing is obviously unacceptable. While lockout and quarantine procedures are part of safety discipline, they must be applied as part of a controlled shutdown rather than as the sole action; the instruction emphasizes initiating a secure shutdown at the earliest safe moment to neutralize the threat effectively.
