DASH® Black Maxx™ nitrile exam gloves provide comfortable, reliable protection against a variety of substances – including opioids. Testing performed at ARDL (A2LA accredited laboratory) showed that Fentanyl did not permeate Black Maxx™ gloves up to 240 minutes of exposure. The dark black color makes it easy to see when hands have come into contact with potentially hazardous powders/substances.
