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: "laboratory personnel have specific training in handling pathogenic agents and are directed by competent scientists." [24] [25] Access to the laboratory is limited when work is being conducted.
Biosafety level refers to the stringency of biocontainment precautions deemed necessary by the Centers for Disease Control and Prevention (CDC) for laboratory work with infectious materials. Typically, institutions that experiment with or create potentially harmful biological material will have a committee or board of supervisors that is in ...
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 (bacteria, viruses, and toxins) is required, usually by isolation in environmentally and biologically secure cabinets or rooms, to prevent accidental infection ...
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.
Preparation of microbiological samples in a laminar chamber. A laminar flow cabinet or tissue culture hood is a partially enclosed bench work surface designed to prevent contamination of biological samples, semiconductor wafer, or any particle-sensitive materials.
Although construction sites face significantly the same hazards, the rate of accidents varies in different regions and countries due to a variety of safety cultures and workers' behavioral safety. [5] [6] [7] Construction incurs more occupational fatalities than any other sector in both the United States and in the European Union.
An interstitial space is an intermediate space located between regular-use floors, commonly located in hospitals and laboratory-type buildings to allow space for the mechanical systems of the building. By providing this space, laboratory and hospital rooms may be easily rearranged throughout their lifecycles and therefore reduce lifecycle cost.
A hazard and operability study (HAZOP) is a structured and systematic examination of a complex system, usually a process facility, in order to identify hazards to personnel, equipment or the environment, as well as operability problems that could affect operations efficiency.
