Which components are required for triple packaging of Category A infectious substances?

• A. Double-layer waterproof packaging; absorbent material; documentation enclosed by outer packaging
• B. Triple packaging is not required for Category A
• C. Absorbent material only
• D. Documentation enclosed by outer packaging

Answer: (A)

Category A infectious substances must be shipped using three levels of containment: an inner primary leakproof container, a secondary leakproof container, and a rigid outer packaging. Absorbent material belongs inside the secondary container so that any leakage from the primary container is absorbed, and the documentation must be placed in a waterproof pouch attached to the outer packaging. The option that lists double-layer waterproof packaging (representing the two containment layers), includes absorbent material, and has the documentation enclosed by the outer packaging, meets all these requirements. The other choices omit one or more essential elements: claiming triple packaging isn’t required, or mentioning only absorbent material, or mentioning only documentation without the containment layers and absorbent.
