Engines

The NWCG categorizes information on fire apparatus into logical groups and provides common options often requested by fire managers. The Incident Command System (ICS) uses this system based on the equipment capability. The table below shows NWCG minimum performance requirements for structure and, wildland engine resource types. Additional information for required crew training and equipment recommendations can be found at the position catalog.

 Off-Highway Vehicles (OHVs)

In the OHV typing standard NWCG categorizes information on OHVs into logical groups and provides important safety requirements for the occupants. The typing is not meant to address all specialized applications such as water handling, ground ignition, or medical support. However, these requirements can be added within the context of the typing by only allowing certain specialized applications to be done on certain OHV types or specifying higher than minimum or additional requirements such as power.

Base operational weight is only used for typing. Final in-service weight will be higher and include additional accessories such as plow, winch, grapple, forestry package, etc. Final in-service weight must be used when calculating hauler capacity, bridge weight limits, etc.

 

This section lists many of the different initial attack engines used in the United States and describes the wide variety of vehicle sizes, pump, and tank size configurations. The data displayed in this section are intended to assist individuals interested in outfitting an initial attack wildland engine. Some of the following engines could possibly be reclassified from one NWCG ICS type to another by changing the basic equipment compliment, personnel staffing, or level of training.

Water Tenders

The National Wildfire Coordinating Group (NWCG) provides national leadership to enable interoperable wildland fire operations among federal, state, Tribal, territorial, and local partners. NWCG operations standards are interagency by design; they are developed with the intent of universal adoption by the member agencies. However, the decision to adopt and utilize them is made independently by the individual member agencies and communicated through their respective directives systems.
