Definition
Disease-causing microorganisms carried in human blood and certain other body fluids that can be transmitted to another person through contact with that blood or fluid. Examples include the hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). In aviation, exposure risk arises when crewmembers assist passengers who are bleeding, injured, or ill, and federal workplace rules require employers to provide training, protective equipment, and exposure-control procedures.
Plain English
Germs that travel in blood and can spread from one person to another. Pilots and flight crew need to know about them because they may have to help injured or sick passengers without putting themselves at risk.
Context Anchor
Pilots may encounter this term in aviation first-aid training, workplace safety training, accident response, or procedures for cleaning up blood after an injury or medical event.
Derivation
From 'blood-borne' (carried in the blood) and 'pathogen,' from the Greek pathos (suffering, disease) and -genes (producing). Literally, 'disease-producers carried in blood.' The plain meaning of the parts lines up with the medical meaning, which makes the term easy to remember.
Why Pilots Care
Protects against infection risk when assisting injured passengers or crew or cleaning contaminated surfaces after an incident.
Intuition Check
Do not think of bloodborne pathogens as only visible blood. Some body fluids can also carry them, and the germs themselves cannot be seen without testing.
Example Sentence 1
The flight attendant put on gloves before assisting the bleeding passenger, following her airline's bloodborne pathogens procedures.
Example Sentence 2
Annual safety training covers bloodborne pathogens to ensure pilots know proper protective steps during emergencies.
