Coming in contact with someone else's blood or other bodily fluids is dangerous, this could cause illness or death. Bloodborne Pathogens are pathogenic microorganisms that appear in human blood can cause diseases such as Hepatitis B and Human Immune deficiency disease, leading to serious illness such as liver disease or AIDs.

     Any occupation where body floods such as blood, vomit, or saliva may exist is called occupational exposure. This means that pathogens are capable of coming in contact with the worker's mucus membrane, nose, mouth; or it may break the skin with needles pricks and cuts.

The CDC established the Universal Precaution approach, which means that all blood and bodily fluids should be considered infectious and care should be taken in order to minimize the risk of exposure. Owners and employees should always follow universal precautions. Each job site should have a written exposure control plan that is updated annually. Supervisors should be able to provide this plan upon request.
