What signs need to be posted on the CBRN cage?

• A. No eating, drinking or smoking signs and a caution, radioactive materials sign
• B. No eating sign only
• C. No smoking sign only
• D. Caution, chemical hazard sign

Answer: (A)

In this scenario, the signs on the CBRN cage must clearly communicate two safety messages at once: what not to do near the contents, and what kind of hazard is inside. The first part—“No eating, drinking or smoking”—helps prevent ingestion or inhalation of any contaminants that could be on or around the cage. The second part—“Caution, radioactive materials”—alerts anyone nearby that the cage contains radioactive material, signaling the need for radiological precautions such as avoiding close contact, using shielding, and limiting exposure time. Together, these signs cover both precautions: stopping unsafe behaviors that could lead to contamination and warning about the radiological hazard present. The other options miss one of these essential elements—either they don’t warn about radiation, or they don’t explicitly prohibit eating, drinking, or smoking—which is why they aren’t sufficient on their own.
