What is the diamond on chemicals called?

Each color-coded section of blue, red, yellow, and white represents a different type of hazard. With the exception of the bottom white diamond, there will be a number that corresponds to the level of danger a chemical poses. On a scale of 0-4, zero represents no hazard at all and four represents an extreme hazard.

Laboratory Grading of Fire A 3-D scan of the actual diamond is mathematically ray-traced and the effects of 32,000 rays are calculated. The diamond is graded for brightness, contrast, light leakage, and dispersion.

What is the numeric scale used in a safety diamond?

Chemical substances are rated for degree of HEALTH RISK (blue diamond), FLAMMABILITY (red diamond), REACTIVITY (yellow diamond), on a scale of 0 to 4. The white diamond is used to indicate the presence of large quantities of chemicals possessing unusual water reactivity (W) or oxidative capability (oxy).

What does a 4 in reactivity stand for on the hazardous material diamond?

About the Numbering Scale. The blue, red, and yellow fields (health, flammability, and reactivity) all use a numbering scale ranging from 0 to 4. A value of zero means that the material poses essentially no hazard; a rating of four indicates extreme danger.

What are the 4 quadrants of the hazardous materials diamond?

The system uses a color-coded diamond with four quadrants in which numbers are used in the upper three quadrants to signal the degree of health hazard (blue), flammability hazard (red), and reactivity hazard (yellow). The bottom quadrant is used to indicate special hazards.

What are fire diamonds?

A diamond’s “fire” is the effect produced when white light disperses into rainbow colors when it hits the diamond’s facets (the angled cuts in the stone). There are two main kinds of facets: Physical facets and virtual facets. A physical facet is an actual cut in a diamond.
