A CAL FIRE crew strike team consists of a strike team leader, and two fire crews. All CAL FIRE fire crews are Type I crews. These crews are highly trained wildland firefighters and are fully equipped to respond to wildland fires anywhere in the state with minimal support. Each fire crew carries enough supplies and food to last for about two days. The only additional support that would be needed is drinking water and fuel for chainsaws. The minimum staffing for a Type I crew strike team is 30 firefighters.
CAL FIRE maintains 196 fire crews, housed in 39 Conservation Camps throughout the state. A CAL FIRE fire crew consists of a fire captain and 15 to 17 firefighters. The firefighters that make up these crews are minimum-security inmates and wards from the California Department of Corrections and Rehabilitation (CDCR). These fire crews are directly supervised by a CAL FIRE fire captain. CAL FIRE fire crews are the infantry of the Department’s firefighting “ground attack” resources. Their primary function is to construct fire line by hand in areas where heavy machinery cannot be used because of steep topography, rocky terrain, or areas that may be considered environmentally sensitive.

Space cleared of vegetation as required by law, regulation, easement, etc., for the purpose of preventing fires.
Application of specific codes based on statutory mandated conducted through inspection.
A fire is contained when it is surrounded on all sides by some kind of boundary but is still burning and has the potential to jump a boundary line. The boundary may be a “fire line” which is a strip of area where the vegetation has been removed to deny the fire fuel, or a river, a freeway or some other barrier which is expected to stop the fire. Hose lines from fire engines may also contribute to a fire being surrounded and contained. A fire is controlled when there is no further threat of it jumping a containment line. While crews continue to do mop-up work within the fire lines, the fire fight is over.
In California, the six counties that provide fire-prevention services in state responsibility areas under contract with the state. These counties are Marin, Kern, Santa Barbara, Ventura, Los Angeles and Orange.
Contract Counties (CAL FIRE Pays Local Government for Services) Section 4133 of the Public Resources Code and Section 55607 of the Government Code permit the CAL FIRE Director to contract with counties for protection of State Responsibility Area (SRA).

By creating a fire safe landscape of at least 100 feet around your house, you will reduce the chance of a wildfire spreading onto your property and burning through to your home. This is the basis for creating a "defensible space" - an area that will help protect your home and provide a safety zone for the firefighters who are battling the flames. Clearing all flammable vegetation a minimum of 100 feet around your home and other structures will not only provide you with the greatest chance for survival, it is also required by California law.
An area either natural or manmade where material capable of causing a fire to spread unchecked has been treated, cleared, reduced or changed in order to act as barrier between the advancing wildfire and the loss to life, property or resources. This concept is vital for firefighter safety and provides the single significant element of protection of individual property owners. Adequate space (free from flammable vegetation) between structures and flammable vegetation, which allows firefighters a safe working area within which to attack an oncoming wildfire, or the area within the perimeter of a parcel, development, neighborhood or community where basic wildland fire protection practices and measures are implemented, providing the key point of defense from an approaching wildfire or defense against encroaching wildfires or escaping structure fires, or The perimeter as used in this regulation is the area encompassing the parcel or parcels proposed for construction and/or development, excluding the physical structure itself.

CAL FIRE uses its Super Huey helicopters for fast initial attack on wildfires. The copters are able to quickly deliver a nine-person fire crew wherever needed as well as battle fires with water/foam drops. The copters are also used for medical evacuations, backfiring operations on wildland fires, to ignite prescribed burns using either a helitorch or a ping-pong ball machine - Chemical Ignition Device System (CIDS), cargo transport (internal and external loads), re-seeding operations, infra-red mapping of incidents, and numerous non-fire emergency missions. Since 1997, CAL FIRE helicopter crews have been trained to do "short haul" rescues. Short haul involves a crew member being lowered from a hovering helicopter to an injured or trapped person below. Once hooked to a harness or basket, both the victim and crew member are then carried a short distance to safety.

An incident base is the command and control location for all personnel and equipment working an incident. Incident bases are set up within a close but safe proximity to the incident. The incident base is similar to a small city complete with sleeping areas, feeding areas, toilets, showers, and equipment repair facilities.
Initial attack means the first attack on the fire. The number of resources sent on the first dispatch to a wildfire depends upon the location of the fire, the fuels in the area (vegetation, timber, homes, etc) and current weather conditions. Municipal fire departments would call this the first alarm. Most fires are caught within the first burn period (the first two hours). Therefore, the vast majority of the fires CAL FIRE responds to are considered initial attack fires.
The geographical meeting point of two diverse systems, wildland and structures. At this interface, structures and vegetation are sufficiently close that a wildland fire could spread to structures or a structure fire ignites vegetation.
Interspersing of developed land with wildland, where there are no easily discernible boundaries between the two systems. An example would be what real estate brochures describe as “ranchettes” or “weekend farmer” homes. This poses more problems in wildland fire management than interface.

The California Department of Forestry and Fire Protection (CAL FIRE) has developed Major Incident Command Teams (ICT) to manage large complex incidents. CAL FIRE maintains 10 Incident Command Teams, five in the Northern Region and five in the Southern Region. Each day of the year two CAL FIRE Incident Command Teams are ready for deployment anywhere in the state, or outside of California if requested.
A Major Incident Command Team consists of 16 highly trained and certified individuals and 10 trainees that, as a team, provide incident management skills for any type of disaster, regardless of location. Each team includes members with the experience and skills to fill responsibilities including incident commander, planning, finance, logistics, safety, information, and air operations to name a few.
The CAL FIRE MICT works under the direction of the local jurisdiction having statutory responsibility for the incident. If it is a wildland fire on State Responsibility Area (SRA) then CAL FIRE is the lead for all activities in the suppression effort. If a wildland fire were to occur on both SRA and federal lands, then a unified command may occur. If, however, it is an earthquake or hazardous materials spill within an urban area, CAL FIRE may be called in to assist in the management of the incident, but the overall lead would be the local agency of jurisdiction.
CAL FIRE MICTs manage large complex wildland fires on a regular basis as well as major hazardous materials incidents, flood fighting operations, earthquakes and other incidents or activities needing a management structure.
