Which statement about wet-evidence packaging is accurate?

• A. Wet evidence must always be sealed in plastic bag
• B. Wet evidence should be air-dried immediately
• C. Wet evidence should be kept in metal container
• D. Wet evidence may be packaged in non-porous for short time

Answer: (D)

When you’re dealing with wet evidence, the priority is to contain the liquid, prevent leaks, and limit contamination while moisture is managed. Using a non-porous container for a short period provides secure containment that keeps moisture from seeping into other items and reduces the risk of spreading contaminants during transport. It buys time to transfer the item to a controlled area where it can be dried properly without letting moisture escape or promote mold growth. Air-drying is ideal in the right environment, but it isn’t always immediately feasible, so a short-term non-porous packaging solution preserves the integrity of the evidence until drying can occur. Avoid porous packaging for wet items because moisture can be absorbed or wick into surrounding materials, potentially compromising the sample. And while metal containers are non-porous, they’re not the standard choice for wet evidence due to practical concerns. Long-term storage should involve appropriate drying and then packaging in a suitable, often porous, container to prevent future moisture buildup.
