The following graphical symbols are for use on operator controls and other displays on fire and rescue apparatus. These symbols are appropriate for vehicles designed to meet NFPA 1901 Standard for Automotive Fire Apparatus, NFPA 1906 Standard for Wildland Apparatus, and NFPA 414 Standard for Airport Rescue and Fire Fighting Vehicles.

The artwork and information in this area gives the fire and rescue community an option for labeling common controls with a graphical representation of their function. This can be either in place of, or in addition to, the traditional text description. Some symbols have been adopted from already established sources, and many of the symbols are identical or similar to those being developed for use in Europe.
