For the NFPA Standard System to the Identification of Fire Hazards the 1991 edition of the Fire Protection Guide of Hazardous Materials was used. 

The health rating is provided on the left at the 9 o clock position and is colored blue. The flammability rating is provided at the top or 12 o clock position and is colored red. The reactivity hazard is provided on the right at the 3 o clock position and is colored yellow. The relative rankings for each hazard are indicated in each quadrant. Special hazard identifiers are provided in the bottom quadrant at the 6 o clock position, which is usually white. Special hazard qualifiers generally include radioactivity, explosives, corrosive, water reactive, oxidizer, etc. The NFPA fire hazard identification scheme is somewhat limited as it only identifies relative potential hazards with the individual material. It does not identify the material itself or all of its potential reactions with other materials. See Figure C.3 for a depiction of this placard.

For most flammable hydrocarbons, the LFL is around 2%—5%. For simple alkanes, such as methane and ethane, the UFL is in the 10%—15% range. Some chemicals, such as hydrogen, ethylene oxide, and acetylene, have much higher values for UFL. Values for flammable limit ranges for many flammable materials are provided by NFPA 704—Standard System for the Identification of the Hazards of Materials for Emergency Response.
