This is a summary of some important controls used for work in containment level 2 laboratories but is not exhaustive and you will need to do other things as well depending on your specific work, local policies, risk assessments, regulatory requirements and licences.
What is containment level?
The containment level needed depends on the regulatory requirements, the overall nature of the work and the risk assessments. The physical containment level is used to determine which controls are required.
What is a BSL-1 lab?
A BSL-1 lab, which is not required to be isolated from surrounding facilities, houses activities that require only standard microbial practices, such as: Mechanical pipetting only (no mouth pipetting allowed) Safe sharps handling. Avoidance of splashes or aerosols.
What are the requirements for a BSL-3 lab?
Common requirements in a BSL-3 laboratory include: Standard personal protective equipment must be worn, and respirators might be required. Solid-front wraparound gowns, scrub suits or coveralls are often required. All work with microbes must be performed within an appropriate BSC.
What is the lowest level of biosafety?
As the lowest of the four, biosafety level 1 applies to laboratory settings in which personnel work with low-risk microbes that pose little to no threat of infection in healthy adults. An example of a microbe that is typically worked with at a BSL-1 is a nonpathogenic strain of E. coli.
What is BSL in biology?
Biological Safety Levels ( BSL) are a series of protections relegated to autoclave -related activities that take place in particular biological labs. They are individual safeguards designed to protect laboratory personnel, as well as the surrounding environment and community.
What are some examples of microbes in BSL3?
Examples of microbes worked with in a BSL-3 includes; yellow fever, West Nile virus, and the bacteria that causes tuberculosis. The microbes are so serious that the work is often strictly controlled and registered with the appropriate government agencies.

Biosafety level one , the lowest level, applies to work with agents that usually pose a minimal potential threat to laboratory workers and the environment and do not consistently cause disease in healthy adults. Research with these agents is generally performed on standard open laboratory benches without the use of special containment equipment.
How are biological safety levels ranked?
Biological safety levels are ranked from one to four and are selected based on the agents or organisms on which the research or work is being conducted. Each level up builds on the previous level, adding constraints and barriers.
Level 2 background check
A Level 2 background check ensures that no person has been arrested for a criminal offense that may include murder, negligence, and sexual misconduct, domestic violence, healthcare-related crimes, etc.
Level 1 and Level 2 background check differences
A Level 1 background check is a name-based check for employment history and criminal record. A Level 1 check is limited to state jurisdiction using the applicant’s name and carried out by state and local law enforcement agencies.
A case of background check
Background checks ensure a safe workplace by providing critical information about a person's history and background. They help minimize risks and threats associated with hiring or retaining an employee with a devious track record. Background screenings are becoming increasingly common, especially as an essential pre-employment condition.

What is a BSL-4 lab?
BSL-4 laboratories are generally set up to be either cabinet laboratories or protective-suit laboratories. In cabinet laboratories, all work must be done within a class III biosafety cabinet. Materials leaving the cabinet must be decontaminated by passing through an autoclave or a tank of disinfectant.
What is a BSL level?
A biosafety level ( BSL ), or pathogen/protection level, is a set of biocontainment precautions required to isolate dangerous biological agents in an enclosed laboratory facility. The levels of containment range from the lowest biosafety level 1 (BSL-1) to the highest at level 4 (BSL-4). In the United States, the Centers for Disease Control and Prevention (CDC) have specified these levels. In the European Union, the same biosafety levels are defined in a directive. In Canada the four levels are known as Containment Levels. Facilities with these designations are also sometimes given as P1 through P4 (for pathogen or protection level), as in the term P3 laboratory.
What is BSL-1?
Biosafety level 1 (BSL-1) is suitable for work with well-characterized agents which do not cause disease in healthy humans. In general, these agents should pose minimal potential hazard to laboratory personnel and the environment. At this level, precautions are limited relative to other levels. Laboratory personnel must wash their hands upon entering and exiting the lab. Research with these agents may be performed on standard open laboratory benches without the use of special containment equipment. However, eating and drinking are generally prohibited in laboratory areas. Potentially infectious material must be decontaminated before disposal, either by adding a chemical such as bleach or isopropanol or by packaging for decontamination elsewhere. Personal protective equipment is only required for circumstances where personnel might be exposed to hazardous material. BSL-1 laboratories must have a door which can be locked to limit access to the lab. However, it is not necessary for BSL-1 labs to be isolated from the general building.
What is level 4 biosafety?
Biosafety level 4 laboratories are used for diagnostic work and research on easily transmitted pathogens which can cause fatal disease.
When was the first Class III biosafety cabinet made?
The first prototype Class III (maximum containment) biosafety cabinet was fashioned in 1943 by Hubert Kaempf Jr., then a U.S. Army soldier, under the direction of Arnold G. Wedum, Director (1944–69) of Industrial Health and Safety at the United States Army Biological Warfare Laboratories, Camp Detrick, Maryland.
How many nanometers should a biohazard filter be?
Ideally, it should filter particles down to 10 nanometers, and release of a particle 50 nanometers or larger is unacceptable under any circumstance.
