There are four biosafety levels.
Each level has specific controls for containment of microbes and biological agents.
The primary risks that determine levels of containment are infectivity, severity of disease, transmissibility, and the nature of the work conducted..
Essential components of the biosafety guidelines contain some or all the following, depending on the facility: bio-risk assessment and identification; specific biosafety measures, which cover the code of practice, physical plant such as laboratory design and facilities, equipment acquisition and maintenance, medical .
Biosafety is a framework that describes the use of specific practices, training, safety equipment, and specially designed buildings to protect the worker, community, and environment from an accidental exposure or unintentional release of infectious agents and toxins..
Hand washing after handling biologicals and potentially hazardous materials, after taking off gloves and before leaving the lab.
Avoiding hand-to-face (or mouth) contact.
No eating, drinking, smoking, or applying cosmetics in the lab.
Disinfecting work surfaces daily and decontaminating after spills..
biological agents during laboratory operations must be correctly managed to control biological risks.
Core biosafety requirements for the handling of contaminated waste material require that processes for the identification and segregation of contaminated materials be adopted before decontamination and/or disposal.
Personal protective equipment, such gloves, gowns, hair/shoe covers, N95 respirator masks, and safety goggles.
Work practices, such as:
