What is Step 4 in the leak test procedure for tanks?

• A. Pressurize the container
• B. Choose an appropriate place
• C. Select a leak checking device
• D. Use a leak detector to test for leaks

Answer: (D)

The essential action here is using the right instrument to actively check for leaks. In a leak test, you don’t just pressurize the tank or plan where to test—you perform the actual check with a leak detector. The detector is the tool that reveals escaping propane, giving you a clear signal (audible/visual or through the detector’s readout) when a leak is present. Preparation steps like pressurizing to the required test pressure and selecting a detector are done earlier; the test itself is completed by applying the detector to the tank and its connections to verify there are no leaks. This is why using a leak detector to test for leaks is the correct action.
