A biosafety level is the level of the biocontainment precautions required to isolate dangerous biological agents in an enclosed 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.

Famous quotes containing the word level:
“To punish drug takers is like a drunk striking the bleary face it sees in the mirror. Drugs will not be brought under control until society itself changes, enabling men to use them as primitive man did: welcoming the visions they provided not as fantasies, but as intimations of a different, and important, level of reality.”
—Brian Inglis (b. 1916)
