The diamond is divided into four color-coded squares, each which conveys information about specific hazards present in the area. The top square is red and describes flammability hazards, the leftmost square is blue and describes health hazards, and the rightmost square is yellow and describes reactivity hazards.
What is the diamond on chemicals called?
Fire diamonds located on tanks and buildings indicate the level of chemical hazard located there. The four colors are blue, red, yellow, and white. The numbers superimposed over the colors rank the severity or danger, ranging from one to four, with four being the highest rating.
How does the safety diamond work?
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.
Is the NFPA diamond still used?
“Employers may continue to use rating systems such as National Fire Protection Association (NFPA) diamonds or HMIS requirements for workplace labels as long as they are consistent with the requirements of the Hazard Communication Standard and the employees have immediate access to the specific hazard information as …
How do you read an SDS diamond?
The diamond is broken into four sections. Numbers in the three colored sections range from 0 (least severe hazard) to 4 (most severe hazard). The fourth (white) section is left blank and is used only to denote special fire fighting measures/hazards. NFPA signs and kits are available at Safety Emporium.
What is the fire diamond in chemistry?
NFPA 704 sometimes is called a “fire diamond” because the diamond-shaped sign indicates flammability of a substance and also communicates essential information about how emergency response teams should deal with a material if there is a spill, fire or other accident.
What is the purpose of the fire diamond?
The “Fire Diamond” or “NFPA 704” refers to signs posted at locations that contain hazardous materials. The purpose of the signs are to alert emergency personnel to the risks posed by the materials.
What does a 3 in the blue diamond mean?
Unstable at high temperature and pressure. Reacts with water. 2-Normally unstable but will not detonate. 3-Can detonate or explode but requires strong initiating force or heating under confinement.
What does a 4 on a hazmat diamond meaning?
4. Material that, on very short exposure, could cause death or major residual injury. White for health hazard (W-Water Reactive, OX-Oxidizer)
How can you tell a fire diamond?
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).
How long is the chemical able to be used before it must be labeled with a GHS compliant label?
(See Example 2.) Labels must be legible, in English, and prominently displayed. Other languages may be displayed in addition to English. Chemical manufacturers, importers, and distributors who become newly aware of any significant information regarding the hazards of a chemical must revise the label within six months.
Are NFPA diamonds required?
When am I required to use the NFPA 704 rating system? NFPA 704 labels are required when another Federal, state or local regulation or code requires their use. NFPA 704 does not specify when a container, tank or facility must label with the 704 diamond.
What does NFPA stand for?
The National Fire Protection Association (NFPA) is a global self-funded nonprofit organization, established in 1896, devoted to eliminating death, injury, property and economic loss due to fire, electrical and related hazards.
What’s the purpose of a SDS?
A safety data sheet (SDS), previously known as a material safety data sheet) is an important information source for eliminating or minimising the risks associated with the use of hazardous chemicals (hazardous substances and/or dangerous goods) in workplaces.
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.
Why is it important to read the SDS?
It is important that workers read the SDS carefully and understand its contents before working with a hazardous chemical so that it can be safely stored, handled or used. The SDS can be used to assist in assessing specific risks associated with a chemical and in training workers on how to use a chemical safely.
What are orange diamonds?
Treated orange diamonds are colorless diamonds that have been sent to a lab to be subjected to a chemical process (HPHT) so that the color of the surface of the diamond artificially changes to orange while its interior remains colorless.

- 1 = Slightly hazardous.
- 2 = Hazardous.
- 3 = Extreme danger.
- 4 = Deadly.

What does red diamond says about this chemical?
The red diamond tells how flammable the chemical compound is: how easily it catches fire. The yellow diamond tells about reactivity: how quickly the compound reacts with other materials. (For example, some chemicals, like ammonium nitrate, explode when they touch water; this is an example of reactivity.)
What does the red yellow blue and white diamond mean?
The panel has four areas: Red – Fire hazard. Blue – Health hazard. Yellow – Reactivity. White – Specific hazard.
What does the white diamond represent in the risk diamond?
The white diamond on the NCFA hazard diamond is used for special information. Oxy stands for Oxygen. G means Compressed Gas.
Are yellow diamonds rare?
Yellow Diamonds They are still very rare, but their relatively low price and striking color has made them the most in-demand of the colored diamonds. Yellow diamonds get their color from the element nitrogen, which absorbs blue light in the diamond and reflects a stunning yellow color.
Are pink diamonds real?
The majority of all pink diamonds mined come from one source in Australia, the Argyle Mine. Argyle Pink Diamonds are so expensive because of the very limited supply. A pink diamond is formed of only carbon like a white diamond, through millions of years in the kimberlite pipes of volcanoes.
