What are the 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.

What is the difference between BSL 1 and BSL 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 is the classification of Biosafety Level 1 laboratory?

BSL-1 calls for a basic level of containment that relies on standard microbiological practices with no special primary or secondary barriers recommended, other than a sink for hand washing. Most materials that cannot cause human disease are kept in a BSL-1 area.

What does BSL 2 mean?

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.

What are the Level 4 viruses?

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 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 does Biosafety mean?

Definition of biosafety : safety with respect to the effects of biological research on humans and the environment.

What is the difference between biosafety level 3 and 4?

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 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 4 virus?

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 biosafety level is anthrax?

anthracis), under biosafety level (BSL) 3 containment conditions.

What are Class 4 pathogens?

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. The CDC has many recommendations on how to manage these viruses. There are no bacteria in this group.

How can I avoid getting sick from airborne pathogens?

Although it’s impossible to completely avoid airborne pathogens, there are some things you can do to lower your chances of getting sick: 1 Avoid close contact with people who have active symptoms of disease. 2 Stay home when you’re sick. Don’t let vulnerable people come in close contact with you. 3 If you must be around others, wear a face mask…

Does airborne really work for the common cold?

This statement is required by the FDA, which does not evaluate supplements sold without a prescription. According to Natural Medicines, the only ingredients in Airborne that are “possibly effective” in treating the common cold are echinacea, vitamin C, and zinc.

What are airborne pathogens?

Airborne Pathogens are infectious microorganisms which can be transmitted through air and could cause disease. The discharged microbes may remain suspended in the air on dust particles, respiratory and water droplets. Tuberculosis, or TB, is an airborne pathogen of concern.

What are the treatment options for common airborne diseases?

Treatment for common airborne diseases. Treatment for infants with whooping cough can include antibiotics, and hospitalization is often needed. There are drugs to treat and cure TB, although some strains of TB are drug resistant. Failure to complete the course of medicine can lead to drug resistance and return of symptoms.
