Protective clothing
Blood can contain pathogens such as the Hepatitis B virus, Hepatitis C virus, and the human immunodeficiency virus (HIV). It is essential to regard all biological evidence as potentially infectious and to follow universal safety precautions.
These precautions include the following:
- Wear personal protective equipment (PPE), such as gloves and face masks.
- Avoid eating, applying cosmetics, or any hand-to-face contact (especially mouth and eye).
- Use implements and wear puncture resistant gloves to handle objects that may have been used for intravenous administration of drugs – place these in sharps disposal containers.
- Identify biohazardous evidence material and package in containers with appropriate labeling.
