Which action should you take before patching to prevent further leakage?

• A. Isolation
• B. Repair
• C. Monitor
• D. Wait

Answer: (A)

Isolating the line to stop the flow and contain the leak is the first essential step before patching. By closing the appropriate valves and securing the area, you remove the pressure and flow that could drive more fluid out while you’re applying the patch. This creates a safe, controlled environment for the repair, reduces the risk of the leak worsening, and helps the patch set properly. If you wait or try to patch while the system is still feeding fluid, leakage can continue and the patch may fail or be overwhelmed. Monitoring is important, but it comes after you’ve isolated the leak and applied the patch to verify the repair holds.
