Risk Group 1 (no or low individual and community risk): A microorganism that is unlikely to cause human or animal disease. ORisk Group

The containment laboratory Biosafety Level 3 is designed and provided for work with Risk group 3 microorganisms and with large volumes or high concentrations of risk group 2 microorganisms that pose an increased risk of aerosol spread

Laboratory/facility commissioning may be defined as the systematic review and documentation process signifying that specified laboratory structural components, systems and/or system components have been installed, inspected, functionally tested and verified to meet national or international standards, as appropriate

As aerosols are important sources of infection, care should be taken to reduce the extent of their formation and dispersion Hazardous aerosols can be generated by many laboratory operations, e.g. blending, mixing, grinding, shaking, stirring, sonicating and centrifuging of infectious materials. Even when safe equipment is used, it is best to carry out these operations in an approved biological safety cabinet whenever possible

A basic knowledge of disinfection and sterilization is crucial for biosafety in the laboratory. Since heavily soiled items cannot promptly be disinfected or sterilized, it is equally important to understand the fundamentals of cleaning prior to disinfection (precleaning). In this regard, the following general principles apply to all known classes of microbial pathogens
