How many biosafety levels are there?
There are four biosafety levels.
Each level has specific controls for containment of microbes and biological agents..
How many Biosafety Level 3 labs are there?
Respective surveys showed 29210 and >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.
Where are the Level 4 labs located?
There are currently only four operational BSL-4 laboratory suites in the United States: at the Centers for Disease Control and Prevention in Atlanta; at the United States Army Medical Research Institute for Infectious Diseases at Fort Detrick in Frederick, Maryland; at the Southwest Foundation for Biomedical Research …
Is Ebola a Level 4 pathogen?
An example of a level 4 disease is Ebola virus, a disease that causes headache, muscle pain, fever, impaired liver and kidney function, and in some cases, death. Since last year, Ebola virus has infected over 18,000 people, according to the World Health Organization (WHO).
What Biosafety Level is E coli?
Follow requirements and practices for your assigned BSL:Biosafety levels (BSL)BSL–11. Degree of hazardLow risk: Well characterized agents not known to cause disease in healthy adult humans2.

What is Biosafety Level 3?
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.
What is Biosafety Level 4?
Biosafety level 4 (BSL-4) is the highest level of biosafety precautions, and is appropriate for work with agents that could easily be aerosol-transmitted within the laboratory and cause severe to fatal disease in humans for which there are no available vaccines or treatments.
What are Level 4 agents?
Level 4. Agents requiring BSL 4 facilities and practices are extremely dangerous and pose a high risk of life-threatening disease. Examples are the Ebola virus, the Lassa virus, and any agent with unknown risks of pathogenicity and transmission. These facilities provide the maximum protection and containment.
What is Biosafety Level 2?
Biosafety Level 2 (BSL-2) BSL-2 laboratories are used to study moderate-risk infectious agents or toxins that pose a moderate danger if accidentally inhaled, swallowed, or exposed to the skin.
What is the full form of BSL?
BSL: 1. Biosafety level, as in a BSL-4 laboratory. 2. Biohazard safety level.
What are the Level 4 viruses?
Biohazard Level 4 usually includes dangerous viruses like Ebola, Marburg virus, Lassa fever, Bolivian hemorrhagic fever, and many other hemorrhagic viruses found in the tropics.
What diseases are studied in a BSL 4 lab?
Ebola, smallpox, plague—the rogue’s gallery of highly infectious deadly pathogens is frighteningly long and their potential for havoc is great, which is why they can only be studied within the tightly controlled confines of a biosafety level 4 (BSL4) facility.
How many BSL 4 labs are there in the world?
There are currently seven internationally recognized BSL-4 laboratories in the European Union, in five countries (UK, Germany, Sweden, Italy, France) and additional facilities are under construction or are being planned .
What is the highest biosafety level?
A specialized research laboratory that deals with potentially deadly infectious agents like Ebola would be designated as BSL-4—the highest and most stringent level. The reason biosafety levels are so important is because they dictate the type of work practices that are allowed to take place in a lab setting.
What biosafety level is anthrax?
On June 5, 2014, a laboratory scientist in the Bioterrorism Rapid Response and Advanced Technology (BRRAT) laboratory prepared extracts from a panel of eight bacterial select agents, including Bacillus anthracis (B. anthracis), under biosafety level (BSL) 3 containment conditions.
