Respective surveys showed 29210 and \x26gt;60011 operational BSL-3 laboratories.
In 2007, 1,356 BSL-3 laboratories were registered with the Centers for Disease Control and Prevention (CDC) or Animal and Plant Health Inspection Service of the US Department of Agriculture (APHIS-USDA) for select agent research..
The four biosafety levels are BSL-1, BSL-2, BSL-3, and BSL-4, with BSL-4 being the highest (maximum) level of containment.
There are additional specific rules and designations for animal research (ABSL), agricultural research (BSL-Ag), and other types of research..
BSL-3.
BSL-3 builds upon the containment requirements of BSL-2.
If you work in a lab that is designated BSL-3, the microbes there can be either indigenous or exotic, and they can cause serious or potentially lethal disease through respiratory transmission.
Respiratory transmission is the inhalation route of exposure..
The laboratory must consist of an anteroom and laboratory rooms.
The facility must have gas-impermeable walls, ceilings, and floors.
Air gaps under doors are acceptable for directional airflow.
If the door gaps are sealed, the laboratory suite must not leak gaseous decontamination materials..
Containment level 3 laboratory consists of a lobby and laboratory.
Laboratory should contain its own equipment (so far as reasonably practicable).
Laboratory must be sealable to permit fumigation.
Laboratory should be separated from other activities in building..
The laboratory must consist of an anteroom and laboratory rooms.
The facility must have gas-impermeable walls, ceilings, and floors.
Air gaps under doors are acceptable for directional airflow.
If the door gaps are sealed, the laboratory suite must not leak gaseous decontamination materials..
Biosafety level 3 (BSL-3) is applicable to clinical, diagnostic, teaching, research, or production facilities where work is performed with agents that may cause serious or potentially lethal disease through inhalation, to the personnel, and may contaminate the environment..
Common examples of microbes found in BSL-3 labs include yellow fever, West Nile virus, and the bacteria that causes tuberculosis.
Microbes found within biosafety level 3 settings are so serious that work is often strictly controlled and registered through the appropriate government agencies.Nov 3, 2022.
The laboratory must consist of an anteroom and laboratory rooms.
The facility must have gas-impermeable walls, ceilings, and floors.
Air gaps under doors are acceptable for directional airflow.
If the door gaps are sealed, the laboratory suite must not leak gaseous decontamination materials..
The need for careful implementation must be first recognized. Biosafety level 3 (BSL-3) includes ,the control of infectious agents, which can cause both "serious hazards" and can cause a potentially lethal condition to laboratory and community via the respiratory transmission of the organism.
