A set of biocontainment measures called a biosafety level (BSL), also known as a pathogen/protection level, is needed to isolate harmful biological agents in a lab setting. From the lowest biosafety level 1 (BSL-1) to the highest level 4, there are several levels of confinement (BSL-4). The Centers for Disease Control and Prevention (CDC) in the US have established these standards. The same biosafety levels are established by a directive in the European Union.
