The question

What does the DOT classification tag on a refrigerant cylinder tell carriers and handlers?

• AThe technician who filled the cylinder
• BThe date the refrigerant was made
• CThe hazard class of the contentsCorrect answer
• DThe price per pound

Why “The hazard class of the contents” is correct

The Department of Transportation classification tag shows the hazard class of the cylinder's contents, such as nonflammable gas, so carriers handle it correctly. It goes alongside a label identifying the refrigerant itself.

Why the other answers are wrong

• The technician who filled the cylinder — The tag does not identify who filled the cylinder.
• The date the refrigerant was made — Manufacture date is not what the DOT tag shows.
• The price per pound — Pricing is not part of hazard labeling.
