Which of the following options correctly lists materials that can be shipped in industrial containers which have limited hazard to the public and environment?

• A. Radioactive waste; Explosives; Acids
• B. Water; Sand; Gravel
• C. Laboratory samples; Slightly contaminated clothing; Smoke detectors
• D. Fresh produce; Paper; Cardboard

Answer: (C)

The key idea is that some materials can be shipped in industrial packaging under a limited-hazard, or Limited Quantity, provision. This allows shipments with lower hazard potential to use simpler packaging and handling than full hazmat requirements, as long as the items pose only a small risk to people and the environment.

Laboratory samples, slightly contaminated clothing, and smoke detectors fit this category. Lab samples are often small, non-pathogenic, and prepared in a way that keeps risk minimal. Slightly contaminated clothing may carry only a trace level of hazard, and with proper packaging can be kept safely contained. Smoke detectors contain a tiny amount of radioactive material, but is present in such limited quantities and is well-contained that it’s allowed to be shipped in industrial packaging under limited hazard rules.

In contrast, the other options include items that are either not hazardous at all (water, sand, gravel; fresh produce, paper, cardboard) or are far more hazardous (radioactive waste, explosives, acids) and thus require full hazmat packaging and stricter controls rather than industrial containers with limited hazard.
