    Hazard symbols. Each row, column and 2 x 2 box contains the four warnings: toxic, corrosive, flammable and harmful or irritant. Each 2 x 2 box has either written. Flammable materials sign or symbol. 2. Explosion risk sign or symbol. 3. Toxic sign or symbol. 4. Corrosive sign or symbol. 5. Overhead crane sign or symbol. 6. These signs warn of hazards or a hazardous condition that is not likely to be life- threatening. The hazard symbol is black on a yellow background and a triangle.

    Science Laboratory Safety Symbols and Hazard Signs, Meanings Science Laboratory Safety Symbols and Hazard Signs, Meanings In order to maintain a safe workplace and avoid accidents, lab safety symbols and signs need to be posted throughout the workplace By Lab Manager September 07, Depending upon the scientific research being conducted, a lab can be filled with dangerous chemicals, radioactive substances, biological specimens, sharp instruments, breakable glassware, and flammable objects. Thus, those working in labs need to be keenly aware of the many dangers associated with these items. In order to maintain a safe workplace and avoid accidents, lab safety symbols and signs need to be posted throughout the workplace. Researchers, staff, and visitors should note and understand the hazard communication information on the laboratory safety signs, including specific hazardous agents biological, chemical, radiological , physical hazards lasers, magnetic fields present in the space, stated precautions no food or drink allowed , and required personal protective equipment lab coats, eye protection, gloves, etc. The following laboratory safety symbols warn of possible dangers in the laboratory to help lab professionals keep safe and informed. Disclaimer: Please note that the graphics below represent our own creative take on the standard laboratory safety signs and symbols and are not meant to be used in the laboratory. Physical Safety Symbols 1.

    The new symbol is not intended to be generally visible, but rather to appear on internal components of devices that house radiation sources so that if anybody attempts to disassemble such devices they will see an explicit warning not to proceed any further.

    Biohazard symbol used since The biohazard symbol is used in the labeling of biological materials that carry a significant health risk biohazards , including viral samples and used hypodermic needles see sharps waste.

    The article explained that over 40 symbols were drawn up by Dow artists, and all of the symbols investigated had to meet a number of criteria: " i striking in form in order to draw immediate attention; ii unique and unambiguous, in order not to be confused with symbols used for other purposes; iii quickly recognizable and easily recalled; iv easily stenciled; v symmetrical, in order to appear identical from all angles of approach; and vi acceptable to groups of varying ethnic backgrounds.

    The basic outline of the symbol is a plain trefoil , which is three circles overlapping each other equally like in a triple Venn diagram with the overlapping parts erased. The diameter of the overlapping part is equal to half the radius of the three circles.

    The arcs of the inner circles and the tiny circle are connected by a line. Finally, the ring under is drawn from the distance to the perimeter of the equilateral triangle that forms between the centers of the three intersecting circles. An outer circle of the ring under is drawn and finally enclosed with the arcs from the center of the inner circles with a shorter radius from the inner circles.

    May cause fire or explosion; strong oxidiser. Usually found on bleach, oxygen for medical purposes etc. Replaces: Gas under pressure Gas stored under pressure, such as in gas containers. This is a new symbol that wasn't represented under the old classification system. The symbol is a gas cylinder.

    Meanings: Contains gas under pressure - may explode if heated. Contains refrigerated gas - may cause cryogenic burns or injury. Usually found on gas containers. Corrosive Chemicals that may destroy living tissue on contact.

    Matches the previous symbol for corrosion, the pictogram shows corrosion of material and skin. Meanings: May be corrosive to metals.

    In the United States, due to concerns that the skull-and-crossbones symbol's association with pirates might encourage children to play with toxic materials, the Mr. Yuk symbol is also used to denote poison.

    The international radiation symbol also known as the trefoil first appeared in , at the University of California, Berkeley Radiation Laboratory. The modern version used in the US is magenta against a yellow background, and it is drawn with a central circle of radius R , an internal radius of 1.

    The trefoil is black in the international version, which is also acceptable in the US.

    Hazard symbol

    The sign is commonly referred to as a radioactivity warning sign, but it is actually a warning sign of ionizing radiation. Ionizing radiation is a much broader category than radioactivity alone, as many non-radioactive sources also emit potentially dangerous levels of ionizing radiation.

    This includes x-ray apparatus, medical beam cannons and particle accelerators. Non-ionizing radiation can also reach potentially dangerous levels, but this warning sign is different from the trefoil ionizing radiation warning symbol.

    The new symbol, to be used on sealed radiation sources, is aimed at alerting anyone, anywhere to the danger of being close to a strong source of ionizing radiation. The radiating trefoil suggests the presence of radiation, while the red background and the skull and crossbones warn of the danger. The figure running away from the scene is meant to suggest taking action to avoid the labeled material. The new symbol is not intended to be generally visible, but rather to appear on internal components of devices that house radiation sources so that if anybody attempts to disassemble such devices they will see an explicit warning not to proceed any further.

    The biohazard symbol was developed by the Dow Chemical Company in for their containment products. According to Charles Baldwin, [8] an environmental-health engineer who contributed to its development: The article explained that over 40 symbols were drawn up by Dow artists, and all of the symbols investigated had to meet a number of criteria: It is used in the labeling of biological materials that carry a significant health risk, including viral samples and used hypodermic needles see Sharps waste.

    All parts of the biohazard sign can be drawn with a compass and straightedge. The basic outline of the symbol is a plain trefoil , which is three circles overlapping each other equally like in a triple Venn diagram with the overlapping parts erased.

    The diameter of the overlapping part is equal to half the radius of the three circles. The arcs of the inner circles and the tiny circle are connected by a line.

    Finally, the ring under is drawn from the distance to the perimeter of the equilateral triangle that forms between the centers of the three intersecting circles. An outer circle of the ring under is drawn and finally enclosed with the arcs from the center of the inner circles with a shorter radius from the inner circles.

    A chemical hazard label is a pictogram applied to containers of dangerous chemical compounds to indicate the specific risk, and thus the required precautions. There are several systems of labels, depending on the purpose, such as on the container for end use, or on a vehicle during transportation. Several European countries have started to implement these new global standards, but older warning symbols are still used in many parts of the world.
