PHIL Image 10729

ID#:10729
Description:In this 2007 image, a Centers for Disease Control microbiologist was showering inside a Biosafety Level 4 (BSL-4) laboratory decontamination booth, prior to exiting the sealed confines of the BSL-4 lab. The process consists of a 4 minute, 5% Microchem wash, which is followed by a 3 minute rinse with water. See PHIL 10722 for another view of this activity.

The Special Pathogens Branch works with BSL-4 viruses. These viruses are highly pathogenic and require handling in special laboratory facilities designed to contain them.

The definition of biosafety levels:

The term “biosafety level” pertains to the specific combinations of work practices, safety equipment, and facilities, which are designed to minimize the exposure of workers, and the environment to infectious agents.

- Biosafety level 1 applies to agents that do not ordinarily cause human disease.

- Biosafety level 2 is appropriate for agents that can cause human disease, but whose potential for transmission is limited.

- Biosafety level 3 applies to agents that may be transmitted by the respiratory route which can cause serious infection.

- Biosafety level 4 is used for the diagnosis of exotic agents that pose a high risk of life-threatening disease, which may be transmitted by the aerosol route and for which there is no vaccine or therapy.
