- C5
- D7
Show answer & explanationAnswer & explanation
Correct answer: C. 5
Portable tanks must display several permanent markings: the owner's name, the proper shipping name of the material (if designated for a specific material), the UN portable tank identification plate information (including UN packaging symbol, capacity, tare weight, MAWP, test pressure, and date of manufacture/test), and the proper shipping name with UN/NA number for the contents if the tank is not dedicated to a single material.
Why the other options are wrong
- A. This is a plausible distractor if counting all individual elements on the UN plate plus other required markings.
- B. This is too few; many data points are required.
- D. This is a plausible distractor if counting individual elements on the UN plate plus other required markings.
Portable Tank Permanent Markings
Portable tanks must display specific permanent markings including the owner's name, proper shipping name/UN number (if dedicated), and comprehensive information on a UN portable tank identification plate.
- Owner's name or symbol.
- Proper shipping name and UN/NA number (if dedicated).
- UN portable tank identification plate (contains multiple data points).
- Markings ensure traceability and safety information.
Memory trick: Owner's UN plate shows PSN and tank's specs.
