Which of the following is NOT typically considered to be transported in industrial containers with limited hazard to the public and environment?

• A. Slightly contaminated clothing
• B. Laboratory samples
• C. Smoke detectors
• D. Radioactive materials

Answer: (D)

The idea tested here is what kinds of items can be shipped using simple, industrial-style packaging that is designed to limit risk to people and the environment. Slightly contaminated clothing and laboratory samples are the sort of items that can be contained in basic packaging and labeled properly, so they’re typically considered suitable for limited-hazard shipments. Smoke detectors, while they do contain a very small radioactive source, are often handled under restricted or regulated allowances that still rely on special handling and labeling, but the overall hazard in this context is still minimal and their packaging can be more specialized. The key point is that radioactive materials, even in tiny amounts, require strict regulatory controls and dedicated packaging beyond ordinary industrial containers. That’s why radioactive materials are not typically transported in standard industrial containers marketed as limited-hazard shipments.
