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]
Essential features of a biosafety level 4 (BSL-4) laboratory [1] 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 ...
Laboratory accident resulted in two scientists infected and one died. [8] 1971-07-30 1971 Aral smallpox incident: Smallpox Soviet Union The 1971 Aral smallpox incident was the outbreak of viral disease which occurred as a result of a field test at a Soviet biological weapons facility on an island in the Aral Sea. The incident sickened ten ...
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]
Hazardous chemicals present physical and/or health threats to workers in clinical, industrial, and academic laboratories. Laboratory chemicals include cancer-causing agents (carcinogens), toxins (e.g., those affecting the liver, kidney, and nervous system), irritants, corrosives, sensitizers, as well as agents that act on the blood system or damage the lungs, skin, eyes, or mucous membranes.
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 (or potentially contaminated with) pathogens requiring a defined biosafety level.
Biorisk generally refers to the risk associated with biological materials and/or infectious agents, also known as pathogens. [1] The term has been used frequently for various purposes since the early 1990s. [2] [3] The term is used by regulators, security experts, laboratory personnel and industry alike, and is used by the World Health ...
Microbiology laboratories present multiple chemical, biological, and physical hazards that can be mitigated with laboratory safety methods. Biosafety hazards to workers from synthetic biology are similar to those in existing fields of biotechnology, mainly exposure to pathogens and toxic chemicals used in a laboratory or industrial setting.
