Question

Define the criteria for laboratory biosafety level

Answer 1

A biosafety level is a set of biocontainmentprecautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels.In the European Union, the same biosafety levels are defined in a directive. In Canada the four levels are known as Containment Levels.[4] Facilities with these designations are also sometimes given as P1 through P4 (for Pathogen or Protection level), as in the term "P3 laboratory".
