What is a BSL-3 agent?
Biosafety Level 3 (BSL-3) agents are those requiring containment of airborne bacteria, viruses, or toxins, therefore the design and administration of the BSL3 Biocontainment Facility follows strict federal regulations with local oversight provided by the NCSU Institutional Biosafety Committee.
What are BSL-3 organisms list?
Examples of typical BSL-3 biological material
- Bacteria: Yersinia pestis, Brucella abortus, Chlamydia psittaci, Pseudomonas mallei.
- Viruses: West Nile fever, herpes B, hepatitis A.
Which of the following is an example of a BSL-3 agent?
Examples of agents commonly used in BSL-3 work include yellow fever virus, SARS coronavirus, and tuberculosis bacteria. BSL-3 work is often strictly controlled by government agencies, and labs may need to be registered.
What does Biosafety Level 3 involve?
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 are Category 3 pathogens?
Group 3 – An organism that may cause severe human disease and presents a serious hazard to laboratory workers. It may present a risk of spread to the community but there is usually effective prophylaxis or treatment available.
What are the essential requirements for BSL-3?
Prerequisites for the construction of BSL-3/ Assessment of proposed facility.
What are 4 biosafety levels?
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.
What are BSL 2 agents?
BSL-2 risk group contains biological agents that pose moderate risk to personnel and the environment. If exposure occurs in a laboratory situation, the risk of spread is limited and it rarely would cause infection that would lead to serious disease.
What are the different biosafety levels?
What is a Category 3 laboratory?
Category 3 refers to the pathogen in use and not the facility. A sealed laboratory will provide a further barrier in preventing the accidental release of the biological agent. Additionally a SAPO 3 laboratory or facility must be proofed against the entry or exit of insects and/or animals.
What are the characteristics of a Group 3 biological agent?
Hazard group 3 These can cause severe human disease and may be a hazard to employees. The organism may spread to the community but there is usually an effective prophylaxis or treatment available.
Which is one of the three agents of metamorphism?
Metamorphism is a change in mineral composition and/or texture in a rock in response to changing condition. List the three agents of metamorphism and describe the role of each. The three agents of metamorphism are heat, pressure, and chemically active fluids.
What do you need to know about Biosafety Level 3?
Biosafety Level 3 (BSL-3) is the recommended containment for work with agents or toxins that may cause serious or potentially fatal disease through inhalation exposure. Work at BSL-3 requires enhanced facility design, operational controls and special practices,…
How are biosafety levels divided in biological agents?
The descriptions of biosafety levels (BSL) 1 – 4 parallel those in the NIH Guidelines for research involving recombinant DNA. The BSL categories are divided up by risk of disease combined with availability of preventive and therapeutic treatments.
How to distinguish between regional and contact metamorphism?
Distinguish between regional and contact metamorphism. When great quantities of rock are subjected to intense heat and pressure, as ocean during mountain building, regional metamorphism is said to occur.
