These tips will not only help protect crime scene evidence, they may also protect you from bio-hazards.

• Wear double gloves and change the top pair often.
• Use disposable instruments or clean reusable instruments thoroughly before and after each sample is taken to prevent contamination.
• Air-dry wet evidence thoroughly before packaging to prevent mold from forming.
• To prevent degradation, place evidence in new paper bags. DO NOT use plastic bags.
• Seal packages with evidence tape. Avoid using staples in evidence collection because there is a risk of contamination if a person is cut on a staple while unpacking evidence.
