What are BSL-2 conditions?
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. Design requirements for BSL-2 laboratories include hand washing sinks, eye washing stations, and doors that close and lock automatically.
Is there a BSL-4 bacteria?
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. Infections caused by these microbes are frequently fatal and without treatment or vaccines.
What level pathogen is Ebola?
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).
Is Ebola a Level 4 pathogen?
Work with the world’s most deadly agents, including viruses that cause smallpox and viral hemorrhagic fevers, such as Ebola, is done at biosafety level 4 (BSL-4). The first BSL-4 facility was established at CDC in 1967 in response to the emergence of Marburg virus; it was built within a large truck trailer.
When should you disinfect your workbench quizlet?
Terms in this set (20) When should you disinfect your workbench? Before and after lab work.
Is Smallpox a BSL4?
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.
Who BSL 2?
BSL–2. This biosafety level covers laboratories that work with agents associated with human diseases (i.e. pathogenic or infections organisms) that pose a moderate health hazard.
When to use Biosafety Level 1 ( BSL )?
Risk Group 1 (RG1) agents are not associated with disease in healthy adult humans. Biosafety Level 1 (BSL-1) is suitable for work involving well-characterized agents not known to cause disease in healthy adult humans, and of minimal potential hazard to laboratory personnel and the environment.
Why are viral vectors handled at BSL-2?
However, most procedures involving the handling and manipulation of the viral vectors are done at BSL-2 to protect cell cultures and viral stocks from contamination.
What’s the difference between BSL 1 and BSL 2?
BSL-2 laboratories maintain the same standard microbial practices as BSL-1 labs, but also includes enhanced measures due to the potential risk of the aforementioned microbes.
How are BSL lab levels determined by the CDC?
The Centers for Disease Control and Prevention (CDC) sets BSL lab levels as a way of exhibiting specific controls for the containment of microbes and biological agents. Each BSL lab level builds upon on the previous level—thereby creating layer upon layer of constraints and barriers. These lab levels are determined by the following.
