Which of the following is NOT listed as an indicator of a suspicious package?

• A. Unusually bulky or rigid
• B. Oily stains
• C. Restrictive markings
• D. Clean, undisturbed packaging

Answer: (D)

Recognizing indicators of a suspicious package in the field. A package that feels unusually bulky or rigid can hint at concealed contents or added mass; oily stains may indicate leakage or tampering; restrictive markings can be used to mislead or obscure what’s inside. A clean, undisturbed package, on the other hand, does not show these warning signs and isn’t listed as a suspicious-package indicator. If other red flags are present, treat the situation with caution and follow established safety protocols, including isolating the area and notifying the appropriate authorities.
