Biohazard classifications, also known as biohazard levels, are systems used to categorize biological agents based on their potential harm to humans and the environment. These classifications help in managing and containing biological hazards, ensuring the safety of personnel and the public. The most widely recognized biohazard classification system is the Biosafety Level (BSL) system, which is used in laboratories and research facilities.

The BSL system consists of four levels, each representing a higher degree of potential risk:

BSL-1: This level is assigned to agents that pose minimal risk to laboratory personnel and the environment. Examples include common bacteria and viruses like the common cold virus.

BSL-2: This level is for agents that pose a low risk to laboratory personnel and the environment. Examples include agents like hepatitis B and smallpox.

BSL-3: This level is for agents that pose a significant risk to laboratory personnel and the environment. Examples include agents like anthrax and Ebola virus.

BSL-4: This level is for agents that pose a very high risk to laboratory personnel and the environment. Examples include agents like Marburg virus and Ebola virus.

Other biohazard classification systems exist, such as the Risk Group (RG) system used in the United Kingdom and the Pathogen Hazard Group (PHG) system used in Canada. These systems may have different levels and criteria, but they all aim to provide a framework for managing biological hazards.

Proper biohazard classification is crucial for ensuring the safety of laboratory personnel, the public, and the environment. It helps in determining the appropriate containment measures, personal protective equipment, and training required for handling biological agents. Regular review and updating of biohazard classifications are essential to reflect changes in our understanding of biological agents and their potential risks.
