Biosafety refers to the practices and measures taken to protect human health and the environment from harmful biological agents, such as bacteria, viruses, and fungi. It involves the safe handling, containment, and disposal of these organisms in laboratories, healthcare settings, and agricultural environments to prevent accidental exposure or release. Key components of biosafety include risk assessment, proper training for personnel, and the use of protective equipment. Regulations and guidelines, often established by organizations like the World Health Organization (WHO) and the Centers for Disease Control and Prevention (CDC), help ensure that biological research and medical practices are conducted safely.
