Which body part's contact with blood is considered an exposure?

The classification of body parts that are considered an exposure to bloodborne pathogens includes the eyes, mouth, and non-intact skin. This is crucial for understanding infection control protocols within the Oklahoma City Fire Department and similar agencies.

When blood comes into contact with mucous membranes such as those found in the eyes and mouth, or with areas of the skin that are not intact (i.e., cuts, abrasions, or other wounds), there is a potential for transmission of infectious diseases. These areas provide a direct route for pathogens to enter the body, which is why they are highlighted in safety guidelines.

In contrast, the skin's intact surface does not pose the same risk of exposure because the epidermis acts as a barrier to most pathogens. While hands and feet are critical in a first response context, exposure is specifically defined by the ability for pathogens to enter the body directly, emphasizing the significance of non-intact skin along with mucous membrane contact. This understanding is pivotal for emergency responders to protect themselves when dealing with blood or potentially infectious materials.
