A biosafety level (BSL) 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.
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.
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. 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.
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.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.
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.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.
In 1977 Jim Peacock of the Australian Academy of Science asked Bill Snowdon, then Chief CSIRO AAHL if he could have the newly released USA NIH 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 $185 million, built on Corio Oval.The Australian Animal Health Laboratory is a Class 4/ P4 Laboratory.
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.
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.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.
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.This includes various microbes that cause mild disease to humans, or are difficult to contract via aerosol in a lab setting. Examples include Hepatitis A, B, and C viruses, human immunodeficiency virus (HIV), pathogenic strains of Escherichia coli and Staphylococcus , Salmonella , Plasmodium falciparum , and Toxoplasma gondii .
Biosafety level 3 is appropriate for work involving microbes which can cause serious and potentially lethal disease via the inhalation route.This type of work can be done in clinical, diagnostic, teaching, research, or production facilities. Here, the precautions undertaken in BSL-1 and BSL-2 labs are followed, as well as additional measures including:
In addition, the facility which houses the BSL-3 laboratory must have certain features to ensure appropriate containment. The entrance to the laboratory must be separated from areas of the building with unrestricted traffic flow.Additionally, the laboratory must be behind two sets of self-closing doors (to reduce the risk of aerosols escaping). The construction of the laboratory 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 for easy cleaning and decontamination. Additionally, 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. Air from the laboratory must be filtered before it can be recirculated.
Biosafety level 3 is commonly used for research and diagnostic work involving various microbes which can be transmitted by aerosols and/or cause severe disease. These include Francisella tularensis , Mycobacterium tuberculosis , Chlamydia psittaci , Venezuelan equine encephalitis virus, Eastern equine encephalitis virus, SARS coronavirus, MERS coronavirus, Coxiella burnetii , Rift Valley fever virus, Rickettsia rickettsii , several species of Brucella , chikungunya, yellow fever virus, West Nile virus.
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 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. The cabinets themselves are required to have seamless edges to allow for easy cleaning. Additionally the cabinet and all materials within must be free of sharp edges in order to reduce the risk of damage to the gloves. In a protective-suit laboratory, all work must be done in a class II biosafety cabinet by personnel wearing a positive pressure suit. In order to exit the BSL-4 laboratory, 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 laboratory is restricted to trained and authorized individuals, and all persons entering and exiting the laboratory must be recorded.
As with BSL-3 laboratories, BSL-4 laboratories must be separated from areas that receive unrestricted traffic. Additionally 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.
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. Additionally, poorly characterized pathogens which appear closely related to dangerous pathogens are often handled at this level until sufficient data are obtained either to confirm continued work at this level, or to permit working with them at a lower level.This level is also used for work with Variola virus, the causative agent of smallpox, 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.
Sample-return missions that bring back to Earth samples obtained from a Category V body must be curated at facilities rated BSL-4. Because the existing BSL-4 facilities in the world do not have the complex requirements to ensure the preservation and protection of Earth and the sample simultaneously,there are currently at least two proposals to build a BSL-4 facility dedicated to curation of restricted (potentially biohazard) extraterrestrial materials.
The first is the European Sample Curation Facility (ESCF),proposed to be built in Vienna, which would curate non-restricted samples as well as perform BSL-4 processing of restricted material obtained from Category V bodies such as Mars, Europa, and Enceladus. The other proposal is by NASA and is tentatively known as the Mars Sample-Return Receiving facility (MSRRF). At least three different designs were submitted in 2009. If funded, this American facility would be expected to take 7 to 10 years from design to completion, and an additional two years is recommended for the staff to become proficient and accustomed to the facilities. NASA is also assessing a 2017 proposal to build a mobile and modular BSL-4 facility to secure a sample return capsule at the landing site to conduct preliminary biohazard analyses. After completion of biohazard testing, decisions could be made to sterilize the sample or transport all or portions to a permanent quarantine storage facility anywhere in the world.
The systems of such facilities must be able to contain unknown biohazards, as the sizes of any putative alien microorganisms are unknown. Ideally, it should filter particles down to 10 nanometers, and release of a particle 50 nanometers or larger is unacceptable under any circumstance.
According to a U.S. Government Accountability Office (GAO) report published on October 4, 2007, a total of 1,356 CDC/USDA registered BSL-3 facilities were identified throughout the United States.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.

A North Carolina Mosquito & Vector Control Association (NCMVCA) study highlighted safety concerns. In the United States, laboratories can be funded by federal, state, private, non-profit, or academically. The last accounts for 72% of the funding. There is no central monitoring agency accountable for monitoring laboratories and standards vary according to funding, the age of the laboratory, and is dependent on the size and whether it is SA approved.
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.No single federal agency, according to 12 agencies' responses to a GSA survey, has the mission to track the overall number of BSL-3 and BSL-4 labs in the United States. This means no agency is responsible for determining the risks associated with the proliferation of these labs.
Biosafety is the prevention of large-scale loss of biological integrity, focusing both on ecology and human health. These prevention mechanisms include conduction of regular reviews of the 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, as originally conceptualized, was a set of preventive measures designed to reduce the risk of transmission of infectious diseases in crops and livestock, quarantined pests, invasive alien species, and living modified organisms. From the 1990s, in response to the threat of biological terrorism, biosecurity started including the prevention of the theft of biological materials from research laboratories. The emerging nature of biosecurity threats means that small scale risks blow up rapidly, thus an effective policy becomes a challenge for there are limitations on time and resources available for analysing threats and estimating the likelihood of their occurrence.
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 animals.
Plum Island Animal Disease Center of New York (PIADCNY) is a United States federal research facility dedicated to the study of animal diseases. It is part of the DHS Directorate for Science and Technology.
The National Microbiology Laboratory (NML) is part of the Infectious Disease Prevention and Control Branch 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 and is a subordinate lab of the U.S. Army Medical Research and Development Command (USAMRDC), headquartered on the same installation.
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 term "biocontainment" was coined in 1985, but the concept stretches back at least to the 1940s.
The National Emerging Infectious Diseases Laboratories, or NEIDL, is a biosciences facility of Boston University located near Boston Medical Center on Albany Street in the South End neighborhood of Boston, Massachusetts.
The National Bio and Agro-Defense Facility (NBAF) is a planned United States government-run research facility that will replace the 1950s-era Plum Island Animal Disease Center in New York, which is "nearing the end of its lifecycle and is too small to meet the nation’s research needs." The NBAF will be operated under the authority of the U.S. Department of Homeland Security (DHS), with the U.S. Department of Agriculture’s Agriculture Research Service (USDA-ARS) and Animal Plant Health Inspection Service, Veterinary Services (USDA-APHIS-VS) as primary research partners.
The National Institute of Virology, Pune is an Indian virology research institute, and one of the translational science cells part of Indian Council of Medical Research (ICMR). It was previously known as 'Virus Research Center' and was founded in collaboration with the Rockefeller Foundation. It has been designated as a WHO H5 reference laboratory for SE Asia region.
In health care facilities, isolation represents one of several measures that can be taken to implement infection control: the prevention of contagious diseases from being spread from a patient to other patients, health care workers, and visitors, or from outsiders to a particular patient. Various forms of isolation exist, in some of which contact procedures are modified, and others in which the patient is kept away from all others. In a system devised, and periodically revised, by the U.S. Centers for Disease Control and Prevention (CDC), various levels of patient isolation comprise application of one or more formally described "precaution".
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 is the workplace of approximately 500 federal employees.
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 required. 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 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 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 American Biological Safety Association (ABSA) was founded in 1984 to promote biological safety as an essential principle and serve the needs of biosafety professionals. The Association's goals are to represent the interests and desires of practitioners of biosafety, and to be a dispenser of biosafety information.
The National Interagency Biodefense Campus is a facility in Frederick, MD at Fort Detrick. It hosts members of a scientific collaboration, the National Interagency Confederation for Biological Research.
The curation of extraterrestrial samples (astromaterials) obtained by sample-return missions take 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.
