EPA Section 608 Universal Certification ExamCoreHard

A technician is preparing to ship a recovered refrigerant cylinder containing R-407C. According to DOT regulations, which of the following is NOT required for proper labeling and documentation?

  1. AThe cylinder must be labeled with the type of refrigerant.
  2. BThe cylinder must be labeled with the amount of refrigerant by weight.
  3. CThe cylinder must have a DOT classification tag.
  4. DThe cylinder must be painted blue for R-407C.
Show answer & explanation

Correct answer: D. The cylinder must be painted blue for R-407C.

While cylinder colors are commonly used in the HVAC/R industry for identification, they are NOT mandated by DOT regulations for shipping. DOT regulations focus on accurate labeling of contents, weight, and proper hazard classification, not color coding.

Why the other options are wrong

  • A. Required. The type of refrigerant is essential for identification and handling.
  • B. Required. The amount of refrigerant by weight is necessary for safe transport and tracking.
  • C. Required. DOT classification tags indicate the hazard class for safe transportation.

DOT Refrigerant Shipping Requirements

Department of Transportation (DOT) regulations for shipping recovered refrigerants require proper labeling with refrigerant type, weight, and hazard classification, but do not mandate specific cylinder color coding.

  • Cylinder must be DOT approved.
  • Labeled with refrigerant type.
  • Labeled with net weight of refrigerant.
  • Includes DOT hazard classification.
  • Cylinder color is NOT a DOT requirement.

Memory trick: DOT 'Labels' are 'Detailed' but 'Color' is 'Optional'.
