| Numerical Ranking NFPA ranks chemicals numerically according to the hazards associated with them and displays these numbers in the NFPA symbol. They indicate: Health hazards Fire hazards Reactivity Special hazards related to a chemical | View Page |
| Health Hazards The blue diamond on the left side of the NFPA symbol represents health hazards. 0 = no health hazard 1 = a slight health hazard2 = a dangerous health hazard 3 = indicates extreme danger 4 = the chemical is deadly | View Page |
| Fire Hazards The red diamond on the top of the NFPA symbol represents fire hazards. 0 = the chemical will not burn and thus has no flash point 1 = the flash point > 200°F 2 = the flash point < 200°F 3 = the flash point < 100°F 4 = the flash point < 73°F | View Page |
| Reactivity The yellow diamond on the right side of the NFPA symbol represents reactivity. 0 = the chemical is stable 1 = the chemical is normally stable 2 = chemical is unstable 3 = the chemical is explosive4 = the chemical may detonate | View Page |
| Special Hazards The white diamond at the bottom of the NFPA symbol is the special hazard section. If the chemical reacts with water, a strike-out W (W) will appear in this section. OX means the chemical is an oxidizer. COR means the chemical is corrosive. The radioactivity symbol indicates that the chemical is radioactive. | View Page |
