Type A packaging is used for shipping which kind of materials in drums?

• A. Radioactive materials
• B. Flammable liquids
• C. Heavy metals
• D. Biological samples

Answer: (A)

The main idea here is that Type A packaging is designed specifically for radioactive materials that are shipped in drums. It provides a containment system that can withstand normal handling and minor accidents without leaking, offering enough protection for relatively lower-activity radioactive contents. This level of packaging is chosen because it balances protection with practicality for routine transport of such materials.

Flammable liquids, heavy metals, and biological samples require different packaging standards tailored to their hazards. Flammable liquids need packaging that prevents ignition and meets flammable-liquid tests; heavy metals and their shielding or immobilization requirements call for other containment approaches; infectious or biological substances typically require triple containment and special handling beyond what Type A packaging provides. So, for drums carrying radioactive materials, Type A packaging is the appropriate choice.
