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 a Category 2 laboratory?

Containment level 2 (CL 2) is used for work with medium risk biological agents and hazards, genetically modified organisms, animals and plants.

What is a Level 1 lab?

Biosafety Level 1 (BSL-1) BSL-1 labs are used to study infectious agents or toxins not known to consistently cause disease in healthy adults. They follow basic safety procedures, called Standard Microbiological Practices and require no special equipment or design features.

What is the difference between Biosafety Level 1 and Level 2?

The main difference in the work procedures followed in a BSL-1 laboratory and a BSL-2 laboratory is that employees in a BSL-2 laboratory will use a BSC as a primary barrier for potentially hazardous aerosols. … Access to BSL-2 laboratories must be restricted.

What are BSL-2 organisms?

Examples of BSL-2 organisms are: Mycobacterium, Streptococcus pneumonia, Salmonella choleraesuis. BSL-3 risk group contains biological agents that usually cause serious disease (human, animal or plant) or that can result in serious economic consequences. These agents are usually not spread by casual contact.

What is a cat 3 laboratory?

What is a CL3 Laboratory? A CL3 laboratory is required when handling human pathogens that may be transmitted via inhalation, that often have a low infectious dose to produce effects and that can cause serious or life-threatening disease.

How do I get BSL 2 certification?

In order to use biologicals requiring biosafety level 2 (BSL2) or higher containment, the Principal Investigator must register the project with the UR Institutional Biosafety Committee (IBC) and have the lab inspected by Environmental Health and Safety (EH&S) for compliance with the UR biosafety requirements.

How many BSL-4 labs are there in the UK?

How many BSL-4 labs are there in the US?

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 …

What biosafety level is Mycobacterium tuberculosis?

tuberculosis complex should be carried out under Biosafety Level 2 (BSL-2) containment with BSL-3 safety equipment and work practices. Every further manipulation, involving opening of tubes or vessels containing M.

What is a Level 4 biohazard?

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.

What biosafety risks do Level 2 organisms pose?

Level 2. Biosafety level two would cover work with agents associated with human disease, in other words, pathogenic or infectious organisms posing a moderate hazard. Examples are the equine encephalitis viruses and HIV when performing routine diagnostic procedures or work with clinical specimens.

Who BSL 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 PPE is always required in a Biosafety Level 2 bl2 laboratory?

Protective laboratory coats, gowns, smocks, or uniforms designated for lab use must be worn when working with BSL2 materials. This protective clothing is removed and left in the laboratory before leaving for non-laboratory areas (e.g., cafeteria, library, administrative offices).

What BSL means?

Breed-specific legislation (BSL) is the blanket term for laws that either regulate or ban certain dog breeds in an effort to decrease dog attacks on humans and other animals.

What is a level 3 containment facility?

Containment level 3 (CL 3) is used for work with high risk biological agents and hazards, genetically modified organisms, animals and plants.

What is containment laboratory?

The purpose of containment is to reduce exposure of laboratory workers and other persons to, and to prevent escape into the outside environment of, potentially hazardous agents. The three elements of containment include laboratory practice and technique, safety equipment, and facility design.

What is a Category 3 pathogen?

Group 3. Can cause severe human disease and may be a. serious hazard to employees; it may spread to the community, but there is usually effective prophylaxis or treatment available.

What diseases are studied in a BSL 3 lab?

This facility allows our researchers to work on microbes and infectious agents that can cause serious or potentially lethal disease through inhalation, such as yellow fever, West Nile virus, chikungunya, and Mycobacterium tuberculosis, the bacterium that causes tuberculosis.

What is a CDC Biosafety Level 4 laboratory?

Biosafety level 4 laboratories are used for diagnostic work and research on easily transmitted pathogens which can cause fatal disease. These include a number of viruses known to cause viral hemorrhagic fever such as Marburg virus, Ebola virus, Lassa virus, and Crimean-Congo hemorrhagic fever.

What biosafety level is Lassa virus?

Viruses assigned to Biosafety Level 4 include Crimean-Congo hemorrhagic fever, Ebola, Junin, Lassa fever, Machupo, Marburg, and tick-borne encephalitis virus complex (including Absettarov, Hanzalova, Hypr, Kumlinge, Kyasanur Forest disease, Omsk hemorrhagic fever, and Russian Spring-Summer encephalitis).

What type of agent is Mycobacterium tuberculosis?

Tuberculosis (TB) is caused by a bacterium called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick.

What are Level 4 diseases?

Diseases that have high fatality rates and have no known treatments are considered level 4 diseases. 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.

What is contaminant level1?

Containment level 1 (CL 1) is used for work with low risk biological agents and hazards, genetically modified organisms, animals and plants.

What is the highest level of biohazard?

BSL-4 builds upon the containment requirements of BSL-3 and is the highest level of biological safety. There are a small number of BSL-4 labs in the United States and around the world. The microbes in a BSL-4 lab are dangerous and exotic, posing a high risk of aerosol-transmitted infections.

What is the difference between risk group and biosafety level?

Biosafety levels prescribe the work practices, engineering controls, personal protective equipment, and facility requirements required for working with biological agents. The risk group classification is only one factor to consider when determining the appropriate biosafety level for a particular agent.
