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 a publication referred to as BMBL. [2] In the European Union, the same biosafety levels are defined in a directive. [3] In Canada the four levels are known as Containment Levels. [4] Facilities with these designations are also sometimes given as P1 through P4 (for pathogen or protection level), as in the term P3 laboratory. [5]
At the lowest level of biosafety, precautions may consist of regular hand-washing and minimal protective equipment. At higher biosafety levels, precautions may include airflow systems, multiple containment rooms, sealed containers, positive pressure personnel suits, established protocols for all procedures, extensive personnel training, and high levels of security to control access to the facility. Health Canada reports that world-wide until 1999 there were recorded over 5,000 cases of accidental laboratory infections and 190 deaths. [6]
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 (1944–1969) of Industrial Health and Safety at the United States Army Biological Warfare Laboratories, Camp Detrick, Maryland. Kaempf was tired of his MP duties at Detrick and was able to transfer to the sheet metal department working with the contractor, the H.K. Ferguson Co. [7]
On 18 April 1955, fourteen representatives met at Camp Detrick in Frederick, Maryland. The meeting was to share knowledge and experiences regarding biosafety, chemical, radiological, and industrial safety issues that were common to the operations at the three principal biological warfare (BW) laboratories of the U.S. Army. [8] Because of the potential implication of the work conducted at biological warfare laboratories, the conferences were restricted to top level security clearances. Beginning in 1957, these conferences were planned to include non-classified sessions as well as classified sessions to enable broader sharing of biological safety information. It was not until 1964, however, that conferences were held in a government installation not associated with a biological warfare program. [9]
Over the next ten years, the biological safety conferences grew to include representatives from all federal agencies that sponsored or conducted research with pathogenic microorganisms. By 1966, it began to include representatives from universities, private laboratories, hospitals, and industrial complexes. Throughout the 1970s, participation in the conferences continued to expand and by 1983 discussions began regarding the creation of a formal organization. [9] The American Biological Safety Association (ABSA) was officially established in 1984 and a constitution and bylaws were drafted the same year. As of 2008, ABSA includes some 1,600 members in its professional association. [9]
In 1977, Jim Peacock of the Australian Academy of Science asked Bill Snowdon, then chief of the CSIRO's Australian Animal Health Laboratory (AAHL) if he could have the newly released United States' National Institutes of Health and the British equivalent requirements for the development of infrastructure for bio-containment reviewed by AAHL personnel with a view to recommending the adoption of one of them by Australian authorities. The review was carried out by CSIRO AAHL Project Manager Bill Curnow and CSIRO Engineer Arthur Jenkins. They drafted outcomes for each of the levels of security. AAHL was notionally classified as "substantially beyond P4". These were adopted by the Australian Academy of Science and became the basis for Australian legislation. It opened in 1985 costing AU$185 million, built on Corio Oval. [10] The Australian Animal Health Laboratory is a Class 4/ P4 Laboratory. [11] [12]
In 2003, the Chinese Academy of Sciences approved the construction of mainland China's first BSL-4 laboratory at the Wuhan Institute of Virology (WIV). In 2014, the WIV's National Bio-safety Laboratory was built at a cost of 300 million yuan (US$44 million), in collaboration and with assistance from the French government's CIRI lab. [13] [14] [15]
In 2007 a scientific review paper stated that the Canadian Science Centre for Human and Animal Health, which was designed in the early 1990s, "has become the prototype for modern BSL4 laboratories". [16]
Starting with the 2020 COVID-19 pandemic near the facilities of the WIV, work in biocontainment facilities has been politicized, especially in the US Senate for example as the result of Rand Paul's work. [17] Russia asked questions on 25 October 2022 in the United Nations over the presence in Ukraine of biolabs. [18] In April 2023, Sudan's descent into civil war caused worries at the World Health Organization over its National Public Laboratory as contending factions battled over its area and NPL staff were kicked out in favor of installing a military base at its premises. [19] At the time, the facility contained organisms rated at BSL-2. [20]
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. [21] 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. [21] Potentially infectious material must be decontaminated before disposal, either by adding a chemical such as bleach or isopropanol or by packaging for decontamination elsewhere. [21] Personal protective equipment is only required for circumstances where personnel might be exposed to hazardous material. [21] BSL-1 laboratories must have a door which can be closed to limit access to the lab. However, it is not necessary for BSL-1 labs to be isolated from the general building. [22]
This level of biosafety is appropriate for work with several kinds of microorganisms including non-pathogenic strains of Escherichia coli and Staphylococcus , Bacillus subtilis , Saccharomyces cerevisiae and other organisms not suspected to contribute to human disease. [23] Due to the relative ease and safety of maintaining a BSL-1 laboratory, these are the types of laboratories generally used as teaching spaces for high schools and colleges. [22]
At this level, all precautions used at Biosafety level 1 are followed, and some additional precautions are taken. BSL-2 differs from BSL-1 in that:
Biosafety level 2 is suitable for work involving agents of moderate potential hazard to personnel and the environment. [22] This includes various microbes that cause mild disease to humans, or are difficult to contract via aerosol in a lab setting. [26] Examples of pathogens classified as "Risk Group 2" in the United States include seasonal influenza, [27] SARS-CoV-2, [28] hepatitis A, B, and C viruses, human immunodeficiency virus (HIV), pathogenic strains of Escherichia coli and Staphylococcus, Salmonella , Plasmodium falciparum , and Toxoplasma gondii . [26] [29] Notably, the European Union departs from the United States and classifies HIV and hepatitis B – G as Risk Group 3 agents best handled at BSL-3. [30]
Prions, the infectious agents that transmit prion diseases such as vCJD, are typically handled under Biosafety Level 2 or higher. [24] This is due to the lack of any evidence of aerosol transmission and relatively higher infective dose of prion diseases, though some circumstances (such as handling animal-infective prions in a facility which cares for vulnerable animals) would require BSL-3 conditions. [24]
Biosafety level 3 is appropriate for work involving microbes which can cause serious and potentially lethal disease via the inhalation route. [21] This type of work can be done in clinical, diagnostic, teaching, research, or production facilities. [22] Here, the precautions undertaken in BSL-1 and BSL-2 labs are followed, as well as additional measures including:
Also, the facility which houses the BSL-3 lab must have certain features to ensure appropriate containment. The entrance to the lab must be separated from areas of the building with unrestricted traffic flow. [21] Also, the lab must be behind two sets of self-closing doors (to reduce the risk of aerosols escaping). [22] The construction of the lab is such that it can be easily cleaned. Carpets are not permitted, and any seams in the floors, walls, and ceilings are sealed to allow easy cleaning and decontamination. [21] Also, windows must be sealed, and a ventilation system installed which forces air to flow from the "clean" areas of the lab to the areas where infectious agents are handled. [21] Air from the lab must be filtered before it can be recirculated. [21]
A 2015 study by USA Today journalists, identified more than 200 lab sites in the U.S. that were accredited biosafety levels 3 or 4. [31] The Proceedings of a Workshop on "Developing Norms for the Provision of Biological Laboratories in Low-Resource Contexts" provides a list of BSL-3 laboratories in those countries. [32]
Biosafety level 3 is commonly used for research and diagnostic work involving various microbes which can be transmitted by aerosol and/or cause severe disease. These include Francisella tularensis , Mycobacterium tuberculosis , Chlamydia psittaci , Venezuelan equine encephalitis virus, Eastern equine encephalitis virus, SARS-CoV-1, MERS-CoV, Coxiella burnetii , Rift Valley fever virus, Rickettsia rickettsii , several species of Brucella , chikungunya, yellow fever virus, West Nile virus, and Yersinia pestis . [29]
Biosafety level 4 (BSL-4) is the highest level of biosafety precautions, and is appropriate for work with agents that could easily be aerosol-transmitted within the laboratory and cause severe to fatal disease in humans for which there are no available vaccines or treatments. BSL-4 labs 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. The cabinets themselves are required to have seamless edges to allow easy cleaning. Also, the cabinet and all materials within must be free of sharp edges to reduce the risk of damage to the gloves. In a protective-suit lab, all work must be done in a class II biosafety cabinet by personnel wearing a positive pressure suit. To exit a BSL-4 lab, personnel must pass through a chemical shower for decontamination, then a room for removing the positive-pressure suit, followed by a personal shower. Entry into the BSL-4 lab is restricted to trained and authorized individuals, and all persons entering and exiting the lab must be recorded. [21]
As with BSL-3 laboratories, BSL-4 labs must be separated from areas that receive unrestricted traffic. Also, airflow is tightly controlled to ensure that air always flows from "clean" areas of the lab to areas where work with infectious agents is being performed. The entrance to the BSL-4 lab must also employ airlocks to minimize the possibility that aerosols from the lab could be removed from the lab. All laboratory waste, including filtered air, water, and trash must also be decontaminated before it can leave the facility. [21]
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. Other pathogens handled at BSL-4 include Hendra virus, Nipah virus, and some flaviviruses. Also, poorly characterized pathogens which appear closely related to dangerous pathogens are often handled at this level until enough data is obtained either to confirm continued work at this level, or to permit working with them at a lower level. [29] This level is also used for work with smallpox virus, though this work is only performed at the Centers for Disease Control and Prevention in Atlanta, United States, and the State Research Center of Virology and Biotechnology in Koltsovo, Russia. [33]
Sample-return missions that bring back to Earth, samples from a Category V body, must be curated at facilities rated BSL-4. Because the existing BSL-4 facilities in the world do not provide the level of cleanliness needed for such pristine samples, [35] there is a need to design a facility dedicated to curation of restricted (potentially biohazardous) extraterrestrial materials. The systems of such facilities must be able to contain unknown biohazards, as the size of any putative alien microorganism is unknown. Ideally, it should filter particles down to 10 nanometers, and release of a particle 50 nanometers or larger is unacceptable under any circumstance. [36]
Because NASA and ESA are collaborating on the Mars Sample Return campaign, due to return samples from Mars in the early 2030s, the need for a Sample Receiving Facility (SRF) is becoming more pressing. An SRF is expected to take 7 to 10 years from design to completion, [37] [38] and an additional two years is recommended for the staff to become proficient and accustomed to the facilities. [37]
According to a U.S. Government Accountability Office (GAO) report published on 4 October 2007, a total of 1,356 CDC/USDA registered BSL-3 facilities were identified throughout the United States. [39] Approximately 36% of these laboratories are located in academia. 15 BSL-4 facilities were identified in the U.S. in 2007, including nine at federal labs. [39] As of May 2021, there are 42 BSL-4 facilities in operation around the world, with a further 17 planned or under construction. [40]

High-containment labs that are registered with the Centers for Disease Control and Prevention (CDC) and the U.S. Department of Agriculture's (USDA) Select Agent Program must adhere to Department of Defense standards. [105] Since BSL3 and 4 laboratories in the United States are regulated by either the CDC or USDA or another federal agency (depending on the pathogens they handle), no single federal agency is responsible for regulating or tracking the number of these labs. [106] U.S. high-containment laboratories that handle pathogens which are declared as "select agents" must be inspected periodically by the CDC or USDA, adhere to certain standards, and maintain ongoing education on biosecurity and biosafety policies as mandated by law. [107] [108]
Biosafety is the prevention of large-scale loss of biological integrity, focusing both on ecology and human health. These prevention mechanisms include the conduction of regular reviews of biosafety in laboratory settings, as well as strict guidelines to follow. Biosafety is used to protect from harmful incidents. Many laboratories handling biohazards employ an ongoing risk management assessment and enforcement process for biosafety. Failures to follow such protocols can lead to increased risk of exposure to biohazards or pathogens. Human error and poor technique contribute to unnecessary exposure and compromise the best safeguards set into place for protection.
Biosecurity refers to measures aimed at preventing the introduction or spread of harmful organisms intentionally or unintentionally outside their native range or within new environments. In agriculture, these measures are aimed at protecting food crops and livestock from pests, invasive species, and other organisms not conducive to the welfare of the human population. The term includes biological threats to people, including those from pandemic diseases and bioterrorism. The definition has sometimes been broadened to embrace other concepts, and it is used for different purposes in different contexts.
A biological hazard, or biohazard, is a biological substance that poses a threat to the health of living organisms, primarily humans. This could include a sample of a microorganism, virus or toxin that can adversely affect human health. A biohazard could also be a substance harmful to other living beings.
The National Microbiology Laboratory (NML) is part of the Public Health Agency of Canada (PHAC), the agency of the Government of Canada that is responsible for public health, health emergency preparedness and response, and infectious and chronic disease control and prevention.
The United States Army Medical Research Institute of Infectious Diseases is the U.S Army's main institution and facility for defensive research into countermeasures against biological warfare. It is located on Fort Detrick, Maryland, near Washington, D.C., and is a subordinate lab of the United States Army Medical Research and Development Command (USAMRDC), headquartered on the same installation.
One use of the concept of biocontainment is related to laboratory biosafety and pertains to microbiology laboratories in which the physical containment of pathogenic organisms or agents is required, usually by isolation in environmentally and biologically secure cabinets or rooms, to prevent accidental infection of workers or release into the surrounding community during scientific research.
The National Institute of Virology in Pune, India is an Indian virology research institute and part of the Indian Council of Medical Research (ICMR). It was previously known as 'Virus Research Centre' and was founded in collaboration with the Rockefeller Foundation. It has been designated as a WHO H5 reference laboratory for SE Asia region.
The Canadian Science Centre for Human and Animal Health (CSCHAH) is an infectious disease laboratory complex in Winnipeg, Manitoba, owned and operated by the Government of Canada. This modern facility is home to two laboratories: the Public Health Agency of Canada's National Microbiology Laboratory (NML) and the Canadian Food Inspection Agency's National Centre for Foreign Animal Disease (NCFAD). It was the workplace of approximately 550 federal employees prior to the Covid-19 outbreak; since then it has been home to over 800 staff.
Rocky Mountain Laboratories (RML) is part of the NIH Intramural Research Program and is located in Hamilton, Montana. Operated by the National Institute of Allergy and Infectious Diseases, RML conducts research on maximum containment pathogens such as Ebola as well as research on prions and intracellular pathogens such as Coxiella burnetii and Francisella tularensis. RML operates one of the few Biosafety level 4 laboratories in the United States, as well as Biosafety level 3 and ABSL3/4 laboratories.
The Galveston National Laboratory (GNL) in Galveston, Texas, United States, is a high security National Biocontainment Laboratory housing several Biosafety level 4 research laboratories. The lab is run by the University of Texas Medical Branch (UTMB) for exotic disease diagnosis and research. The GNL is one of the 15 biosecurity level 4 facilities in the United States and the largest one in the world located on an academic campus.
A biosafety cabinet (BSC)—also called a biological safety cabinet or microbiological safety cabinet—is an enclosed, ventilated laboratory workspace for safely working with materials contaminated with pathogens requiring a defined biosafety level. Several different types of BSC exist, differentiated by the degree of biocontainment they provide. BSCs first became commercially available in 1950.
Positive pressure personnel suits (PPPS)—or positive pressure protective suits, informally known as "space suits", "moon suits", "blue suits", etc.—are highly specialized, totally encapsulating, industrial protection inflatable garments worn only within special biocontainment or maximum containment (BSL-4) laboratory facilities. These facilities research dangerous pathogens which are highly infectious and may have no treatments or vaccines available. These facilities also feature other special equipment and procedures such as airlock entry, quick-drench disinfectant showers, special waste disposal systems, and shower exits.
The Aeromedical Isolation Team of the US Army Medical Research Institute of Infectious Diseases (USAMRIID) at Fort Detrick, Maryland was a military rapid response team with worldwide airlift capability designed to safely evacuate and manage contagious patients under high-level (BSL-4) bio-containment conditions. Created in 1978, during its final years the AIT was one of MEDCOM’s Special Medical Augmentation Response Teams comprising a portable containment laboratory along with its transit isolators for patient transport. Contingency missions included bioterrorism scenarios as well as the extraction of scientists with exotic infections from remote sites in foreign countries. The AIT trained continuously and was often put on alert status, but only deployed for “real world” missions four times. The AIT was decommissioned in 2010 and its mission was assumed by one of the US Air Force’s Critical Care Air Transport Teams (CCATTs).
The United States Biological Defense Program—in recent years also called the National Biodefense Strategy—refers to the collective effort by all levels of government, along with private enterprise and other stakeholders, in the United States to carry out biodefense activities.
The National Centre for Foreign Animal Disease (NCFAD), located in the Canadian Science Centre for Human and Animal Health in Winnipeg, Manitoba, is part of the Canadian Food Inspection Agency’s National Centres for Animal Disease. NCFAD is co-located with the Public Health Agency of Canada’s National Microbiology Laboratory.
The curation of extraterrestrial samples (astromaterials) obtained by sample-return missions takes place at facilities specially designed to preserve both the sample integrity and protect the Earth. Astromaterials are classified as either non-restricted or restricted, depending on the nature of the Solar System body. Non-restricted samples include the Moon, asteroids, comets, solar particles and space dust. Restricted bodies include planets or moons suspected to have either past or present habitable environments to microscopic life, and therefore must be treated as extremely biohazardous.
The Wuhan Institute of Virology, Chinese Academy of Sciences is a research institute on virology administered by the Chinese Academy of Sciences (CAS), which reports to the State Council of the People's Republic of China. The institute is one of nine independent organisations in the Wuhan Branch of the CAS. Located in Jiangxia District, Wuhan, Hubei, it was founded in 1956 and opened mainland China's first biosafety level 4 (BSL-4) laboratory in 2018.
