Biological safety refers to the practices and measures taken to protect people, animals, and the environment from harmful biological agents, such as bacteria, viruses, and toxins. It is essential in laboratories, healthcare settings, and industries that handle potentially dangerous microorganisms. Proper containment, personal protective equipment (PPE), and safety protocols help minimize the risk of exposure and infection. Key components of biological safety include the use of biosafety cabinets, sterilization techniques, and waste disposal methods. Organizations often follow guidelines set by agencies like the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) to ensure safe handling of biological materials.
