Step-by-step explanation:
The hazard diamond is a symbol used to summarize the major hazards of a chemical substance. It provides safety information about certain substances and details flammability, reactivity, health, and other hazards. Within the diamond symbol, there are four quadrants: the top (red) diamond specifies the level of fire hazard, the blue (left) diamond indicates the level of health hazard, the yellow (right) diamond describes reactivity hazards, and the white (bottom) diamond points out special hazards like being corrosive, acidic, alkaline, biologically hazardous, or radioactive. Each hazard is rated on a scale from 0 to 4, with 0 indicating no hazard and 4 indicating extreme hazard.
