Safety & Frequently Asked Questions
First Defense™ Wipes are a presumptive detection tool. A positive result indicates the possible presence of fentanyl and should be handled according to established safety procedures. A negative result does not guarantee that a surface or substance is safe.
Product Basics
What drugs does the First Defense Wipe detect?
First Defense wipes are primarily focused on fentanyl and their derivatives.
How do First Defense Wipes work?
When the primary ingredient in the First Defense wipe comes in contact with fentanyl, it instantly changes color to indicate the presense of fentanyl.
Presumptive Testing & Limitations
What is a presumptive test?
A presumptive test refers to tests or procedures that indicate the possible presence of a substance but does not confirm its actual identity. Presumptive tests are typically used as preliminary screenings to suggest further testing is needed.
Can the wipe produce a false negative?
Yes, fentanyl can be present in various forms such as powder, pills, liquids, solids in very minute quantities.
Fentanyl may be mixed or combined with other compounds, so the wipe may not detect low levels of fentanyl.
A negative/no result on the test cannot guarantee that a harmful drug like fentanyl or other harmful opioids are not present, in another part of the sample or at an undetectable level, and at no time can/should this information be used to assert that a substance is safe.
Users should continue to take safety precautions designed to prevent exposure to dangerous substances during the handling, testing, and/or transporting of suspected controlled substances.
Does First Defense™ neutralize fentanyl?
No. First Defense™ Wipes are designed for presumptive surface detection. They do not neutralize fentanyl, decontaminate surfaces, or make a surface safe to touch. Users should continue to follow all applicable safety protocols.
