Before starting a tank tightness test, which items should be checked visually?

• A. Tank contents level and chemical compatibility.
• B. Tank fittings, seals, manways, access ports, and exterior conditions for obvious damage or leakage signs.
• C. Manufacturer's warranty documents.
• D. Ambient weather conditions.

Answer: (B)

Before starting a tank tightness test, you want to verify that the hardware that could leak or fail under pressure is in good condition. The visual check should focus on the tank fittings, seals, manways, access ports, and the exterior for any obvious damage or signs of leakage. This step catches pre-existing problems that could skew test results or create safety hazards, such as loose connections, worn gaskets, damaged manways, or corrosion around openings. Addressing these issues before the test ensures the reading reflects the tank’s true tightness rather than faults in the hardware. Other items like how much contents are in the tank or whether the chemical is compatible matter for safe operation but aren’t parts of this visual readiness check. Manufacturer warranty documents aren’t relevant to the test itself, and ambient weather isn’t a direct visual indicator of tightness, though it might affect handling outside the testing process.
