What do the colors on the NFPA mean?
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 colors of the NFPA chemical label?
The four bars are color coded, using the modern color bar symbols with blue indicating the level of health hazard, red for flammability, orange for a physical hazard, and white for Personal Protection. The number ratings range from 0-4. The Health section conveys the health hazards of the material.

The NFPA diamond is made up of four smaller diamonds that each have a different meaning and rating. The four smaller diamonds are red,blue,white and yellow. Each color stands for a different category they are health,flammability,reactivity and special.
What does a yellow colored dot label indicate?
reactivity
All of the companies use the color red for flammability, blue for health, and yellow for reactivity as taken from the National Fire Protection Association (NFPA) color code system.
What does a 3 in the Blue diamond mean?

What do the colors represent on the NFPA diamond?
The NFPA diamond has four colors–coded to represent different hazards–and each of those hazards is given a number to indicate severity. Blue indicates a health hazard. Red indicates flammability. Yellow indicates (chemical) reactivity. White contains special codes for unique hazards.
Are fire hydrants color coded?
The tops of hydrants are color coded blue, green, orange, and red tops inform firefighters as to the water flow in the hydrant. Blue hydrants have the highest flow rate and are therefore most desirable. They release water at 1,750 gpm (gallons per minute) and above.
