| There are three classes of materials
which use the fire symbol. |
| 1. |
Flammables can be gases,
liquids or solids. Flammables ignite easily and burn rapidly. Liquid flammables
have a flashpoint under 100 degrees Fahrenheit. |
| 2. |
Combustibles are similar
to flammables, but they do not ignite as easily. Liquid combustibles have
a flash point above 100 degrees Fahrenheit. |
| 3. |
Pyrophoric, or spontaneous
combustion materials, burst into flames "on their own" at temperatures
below 130 degrees Fahrenheit. |
