Biohazard Evidence

Body fluids and other human tissue found on firearms evidence pose health concerns to investigators and crime scene technicians in shooting cases. This most often relates to evidence present in or on blood-soaked or stained clothing, bedclothes, furniture, vehicle upholstery, or other items submitted for gunshot residue analysis and muzzle-to-target distance determinations.
In addition to being dry and appropriately packaged before transfer to the laboratory, evidence containing blood or any body fluid should have biohazard warning labels affixed to the evidence containers to indicate that a potentially infectious material may be present. This labeling warns all concerned to avoid direct contact or exposure to potentially infectious evidentiary materials, whether at the crime scene, in investigative offices, or in laboratory and courtroom environments.
