Which statement about the ASME data plate on a vehicle-mounted tank is true?

• A. It contains critical tank information
• B. It records last fill date
• C. It is decorative
• D. It indicates color

Answer: (A)

The main idea here is that the ASME data plate on a vehicle-mounted tank provides the critical design and service information needed to operate and inspect the tank safely. That plate identifies key specs such as the maximum allowable working pressure, the tank’s capacity, the material and construction details, the manufacturer and date of manufacture, and often hydrostatic test or inspection dates and the ASME code markings. Knowing these values helps prevent overpressurizing the tank, ensures it’s used only for approved contents, and confirms regulatory compliance during inspections.

This plate isn’t decorative, and it doesn’t record the last fill date or indicate the tank’s color. Those details aren’t the information the ASME plate is meant to convey, which is why the statement that it contains critical tank information is the correct one.
