Study Notes

Biological Hazards (Biohazards)

Biohazards include biological agents and toxins harmful to humans, animals, plants, and the environment
Examples include parasites, viruses, bacteria, fungi, prions, toxins, allergens, and venoms
Biohazards can cause disease and environmental damage

Laboratory Biosafety

Protects people, animals, and the environment from biohazards in labs
Methods include specific practices, staff training, safety equipment, and specially designed buildings

Biosafety

A framework for handling biohazards
Aims to prevent accidental exposure or release of infectious agents and toxins
Identifies health risks to humans, animals, agriculture, and the environment
Implements actions to lessen these risks

Biosafety Levels (BSLs)

Designations for lab projects/activities, based on risk severity
BSL-1, BSL-2, BSL-3, and BSL-4 in the US - describe minimum safe practices, building design, and safety equipment needed for infectious agents, toxins, and other biological hazards
