To protect yourself from biohazards and to protect the evidence from becoming contaminated:

  • Use new gloves for each piece of evidence
  • Use clean or new implements to manipulate the sample
  • Minimize contact with the sample (use a swab or forceps, etc.)
  • If possible allow evidence to dry before packaging
  • Collect and package evidence separately
  • Do not fold together a bloodstained garment
  • AVOID DIRECT CONTACT with the evidence sample
