Biological Safety (or biosafety) has paralleled the development of the science of microbiology and its extension into new and related areas including tissue culture, recombinant DNA, animal studies, molecular biology, synthetic biology, and biotechnology. The knowledge and skill gained by research necessary to isolate, manipulate, and propagate pathogenic microorganisms necessitated the development of containment principles, facility design, and practices and procedures to prevent occupational infections in the workplace or release of the organisms to the environment. Biological materials you may not consider to be biohazardous may be regulated by regulations and guidelines as biohazardous materials.
