What color is used for the overall recognition color of the NFPA 704 diamond for reactivity?
What color is used for the overall recognition color of the NFPA 704 diamond for reactivity?
yellow
The National Fire Association (NFPA) has developed a color-coded number system called NFPA 704. 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).
What are the four categories embodied in NFPA 704?
The four divisions are typically color-coded with red on top indicating flammability, blue on the left indicating level of health hazard, yellow on the right for chemical reactivity, and white containing codes for special hazards.
What are the more common oxidizing agents?
The most common oxidizing agents are halogens—such as fluorine (F2), chlorine (Cl2), and bromine (Br2)—and certain oxy anions, such as the permanganate…
What is an oxidizing hazard?
Oxidizers are solids, liquids, or gases that react readily with most organic material or reducing agents with no energy input. Oxidizers are a severe fire hazard. They are not necessarily combustible, but they can intensify combustion and increase the flammable range for chemicals so they ignite more readily.
Which one is the strongest oxidizing agent?
Fluorine
Fluorine, having the largest positive value of electrode potential, is the strongest oxidizing agent.

What are the warning labels for NFPA 704?
NFPA 704 warning labels You may see a warning label on a container or box of containers, such as a case of chemical jugs. These labels provide the most important information you need to know about the substance you are handling. The number system is based on the NFPA 704 rating: Hazard ratings range from 0 to 4, with 4 being the most hazardous.
What kind of oxidizers are included in NFPA 400?
Materials, Annex G.3 Typical Oxidizers to the bench-scale solid oxidizer test method recently added to the Annex of NFPA 400 to determine if the listed Class assignment is consistent with the established burning rate criteria. The Research Foundation expresses gratitude to the report author Elizabeth C. Buc, PhD, PE, CFI,
How to design a NFPA 704 fire placard?
1The placard design is based on the hazard identification system described in Recommended System for the Identification of the Fire Hazards of Materials, National Fire Protection Association (NFPA) 704. 2 For more information, see ES&H Manual, Chapter 37, “Emergency Management.” Hazard Categories
What is the NFPA rating for hazard labels?
You may see a warning label on a container or box of containers, such as a case of chemical jugs. These labels provide the most important information you need to know about the substance you are handling. The number system is based on the NFPA 704 rating: Hazard ratings range from 0 to 4, with 4 being the most hazardous.
