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).
Biological hazards include viruses, bacteria, fungi, prions, and biologically derived toxins, which may be present in body fluids and tissue, cell culture specimens, and laboratory animals. Routes of exposure for chemical and biological hazards include inhalation, ingestion, skin contact, and eye contact. [2]
A biological hazard, or biohazard, is a biological substance that poses a threat (or is a hazard) 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. [a]
Chemical hazard – Non-biological hazards of hazardous materials; Safety engineering – Engineering discipline which assures that engineered systems provide acceptable levels of safety; Security engineering – Process of incorporating security controls into an information system; Select agent – Controlled biological agents in the United States
Hazard analysis critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level. In this manner, HACCP attempts to ...
The USDA animal safety list is located at 9 CFR Subchapter B. [4] Not all select agents require BSL-4 handling, namely select bacteria and toxins, but most select agent viruses do (with the notable exception of SARS-CoV-1 which can be handled in BSL3). Many non-select agent viruses are often handled in BSL-4 according to facility SOPs or when ...
The National Academy of Sciences defines biosecurity as "security against the inadvertent, inappropriate, or intentional malicious or malevolent use of potentially dangerous biological agents or biotechnology, including the development, production, stockpiling, or use of biological weapons as well as outbreaks of newly emergent and epidemic ...
The National Bio and Agro-Defense Facility (NBAF) is a biosafety level 4 research laboratory in Manhattan, Kansas, operated by the United States Department of Agriculture. The facility opened in June 2023. [1] The facility is designed to combat biological threats involving human, zoonotic, and foreign animal diseases.
