Action for GT running leakage:

• A. Secure immediately
• B. Secure at earliest opportunity
• C. Ignore and continue operation
• D. Monitor only

Answer: (A)

When a gas turbine is leaking while it’s running, the immediate priority is safety, so you secure immediately. A leak during operation creates a real fire and explosion hazard because leaked fuel or oil can ignite from hot surfaces or electrical sparks, and any delay gives the threat time to escalate. Shutting down the engine and securing the fuel supply stops feeding the leak and allows safe investigation and actions to prevent ignition. After securing, follow the established emergency shutdown procedures, control ignition sources, and clear the area as needed.

Waiting to secure at earliest opportunity leaves the leak active and the risk ongoing; ignoring or continuing operation maintains the hazard and is not acceptable; monitoring alone does not remove the danger or stop the fuel supply.
