What is the essential step after completing a tightness test to restore normal operation?

• A. Leave all test equipment in place indefinitely
• B. Seal the tank permanently closed
• C. Restore the system and remove testing connections
• D. Move equipment to another site before inspection

Answer: (C)

Restoring normal operation means returning the system to its regular configuration by removing all testing connections and equipment. After you finish the tightness test, safely depressurize if required, disconnect the test apparatus, and take away any hoses, gauges, or ports used for the test so the tank and piping operate as they will in service. This ensures there are no leftover test provisions that could affect normal performance, safety, or operation. Leaving test gear in place would keep the system in a test state and can create hazards or confusion, sealing the tank permanently would prevent use, and moving equipment elsewhere would delay bringing the system back online. So, the proper final step is to restore the system and remove testing connections.
