A Biological Hazard is an organism or substances produced by an organism that may pose a threat to human health. Some examples of how workers can potentially be exposed to Biological Hazards are through the following: bloodborne pathogens, mold and fungi, stinging insects, harmful plants, animal and bird droppings, as well as hazardous waste.
Bloodborne Pathogens
Bloodborne pathogens are infectious microorganisms in human blood that can cause disease in humans. These pathogens include, but are not limited to, hepatitis B (HBV), hepatitis C (HCV) and human immunodeficiency virus (HIV). Needlesticks and other sharps-related injuries may expose workers to bloodborne pathogens.
OSHA's Bloodborne Pathogens Standard, 29 CFR 1910.1030, covers exposures to blood and other potentially infectious materials in workplaces.
