Claim 15:
16. A method of testing a test surface for the presence of a hazardous contaminant, the method comprising:
removing a cap in a first orientation from an elongate body of a collection device to expose an absorbent swab material coupled to an end of the elongate body, the absorbent swab material configured to absorb a first fluid from the test surface, wherein the first fluid is configured to lift the hazardous contaminant from the test surface;
wiping the test surface with the absorbent swab material to collect the hazardous contaminant from the test surface;
reapplying the cap to the elongate body in a second orientation to seal the absorbent swab material to isolate the collected hazardous contaminant within the collection device, wherein the cap further comprises a second fluid; and
releasing the second fluid into the absorbent swab material by pushing the cap onto the elongate body in an orientation in which the absorbent swab material pushes against and opens a frangible seal, wherein when the cap is applied to the elongate body in the first orientation the end of the elongate body is prevented from releasing the second fluid, and wherein when the cap is applied to the elongate body in the second orientation the elongate body causes the second fluid to be released.
