Example: R: 34-37 Causes burns, irritating to the respiratory system. Slashes indicate fixed combinations of single phrases. Example: R: 36/37/38 Irritating to eyes, respiratory system and skin. More detailed hazard and safety information can be found in the material safety data sheets (MSDS) of a compound.
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.
Secondly, the laboratory supervisor, who reports to the laboratory director, is responsible for organizing regular training sessions on laboratory safety. [9] The third point, the personnel must be informed about any special hazards and be required to review the safety or operations manual and adhere to established practices and procedures. The ...
Statements which correspond to related hazards are grouped together by code number, so the numbering is not consecutive. The code is used for reference purposes, for example to help with translations, but it is the actual phrase which should appear on labels and safety data sheets. [5]
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.
Transmission-based precautions are additional infection control precautions – over and above universal/standard precautions – and the latest routine infection prevention and control practices applied for patients who are known or suspected to be infected or colonized with infectious agents, including certain epidemiologically important ...
An example SDS, including guidance for handling a hazardous substance and information on its composition and properties. A safety data sheet (SDS), [1] material safety data sheet (MSDS), or product safety data sheet (PSDS) is a document that lists information relating to occupational safety and health for the use of various substances and products.
An example of a Levey–Jennings chart with upper and lower limits of one and two times the standard deviation. A Levey–Jennings chart is a graph that quality control data is plotted on to give a visual indication whether a laboratory test is working well. The distance from the mean is measured in standard deviations.
