What method is NOT used to transport fentanyl safely?

The correct choice reflects a crucial principle in the safe transport of hazardous substances like fentanyl. Transporting fentanyl by untrained personnel poses significant risks, both to the individuals involved and to public safety. Fentanyl is a highly potent opioid, and improper handling can lead to accidental exposure, overdoses, or even fatalities.

In contrast, methods such as using double-sealed evidence bags, sealed solid containers, and employing personal protective equipment (PPE) are standard practices designed to minimize the risk of exposure and contamination. Double sealing provides an additional layer of security against leakage, while solid containers protect the substance from external elements and reduce the risk of accidental contact. The use of PPE is essential for ensuring that individuals handling fentanyl are protected from potential exposure during transport, which further underscores the importance of proper training and safety measures.

Overall, option C highlights a clear deviation from established safety protocols, emphasizing the importance of having trained personnel handle and transport hazardous materials like fentanyl.
