Making the world better, one answer at a time. The hazard identification signal is a color coded array of four numbers or letters arranged in a diamond shape. The colors are: blue, red, yellow and white. A value of zero means that the material poses essentially no hazard; a ratig of four indicates extreme danger.
What do the numbers and symbols on an NFPA fire diamond mean? 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.
