In the leak test procedure for propane tanks, what is Step 3?

Select a leak checking device

Choose an appropriate place in the plant to perform the inspection

Pressurize the container

Applying pressure to the container is the step that creates the condition under which leaks can be detected. Bringing the tank up to the specified test pressure makes any weak spots, such as joints or fittings, reveal themselves as gas escapes. Once the system is pressurized, a leak detector (or soapy-water test) can reveal leaks at those points. Preparation steps like choosing a leak-checking device are setup tasks that come before the actual test, and using the detector happens after the system is pressurized.
