Which of the following is an example of material that is transported in industrial containers?

• A. Gravel
• B. Fresh fruit
• C. Lumber
• D. Contaminated clothing

Answer: (D)

Industrial containers are designed to securely hold materials that could pose hazards during transport, requiring sealed, labeled containment to protect people and the environment. Contaminated clothing often carries hazardous substances and must go into leak-proof, appropriate industrial containers (such as sealed bags or approved waste drums) for safe transport. This setup prevents exposure and spills and aligns with regulations for hazardous waste transport. The other items—gravel, fresh fruit, and lumber—are typically shipped in standard packaging, pallets, or crates and do not inherently require hazmat industrial containers unless they are contaminated, which makes contaminated clothing the clear example of material transported in industrial containers.
