BB – Bloodborne Exposure

An incident in which blood or other potentially infectious body fluids (e.g. mucus, saliva, urine) may come into contact with the employee’s mucous membranes, non-intact skin, or via parenteral contact in the course of performing job related tasks or procedures.

Exposure events involve two essential factors: a break in the skin OR contact with mucous membranes AND introduction of body fluids from another person.

There are three types of “EXPOSURE EVENTS” of concern:

1. Percutaneous Exposure — is defined as an injury by needle or other object
   contaminated with blood or other body fluid that penetrates the skin or
   mucous membrane.
2. Mucous Membrane Exposure — occurs when blood or other body fluids come
   in contact with mucous membranes lining the eyes, lips, and/or mouth which
   may otherwise be intact.
3. Skin (Increased Risk) Exposures — involve prolonged contact between intact
   skin and blood or other body fluid, or a large area of skin is involved, the skin
   is broken and/or a rash is present, or the source is known to have advanced
   or end-stage AIDS.

The District Allows Any Employee to be Evaluated if Requested Health Services employees do not make the determination if an exposure has occurred or not. Contact Risk Management if you have questions.
