Biocontainment refers to the methods and practices used to prevent the escape of harmful biological agents, such as viruses or bacteria, from a controlled environment. This is crucial in laboratories and facilities that work with dangerous pathogens, ensuring that they do not pose a risk to public health or the environment. Key components of biocontainment include specialized equipment, secure facilities, and strict protocols. For example, biosafety cabinets and negative pressure rooms are designed to contain infectious materials. Additionally, trained personnel follow safety guidelines to minimize the risk of accidental release or exposure.
