Wildfire suppression equipment and personnel
Wildfire suppression equipment and personnel is part of the science of fire fighting focusing on the use of specialized equipment, training and tactics to effectively control, surround and eventually extinguish a natural cover fire. There are several specially designed tools that through their function and user training, perform specialized tasks that are specific to natural cover firefighting. This is used together in conjunction with the general understanding of the behavior of fire to form a viable plan of attack.
PPE or personal protective equipment is generally standardized for a certain type of team or crew. Smokejumpers for example require more protective equipment because of their method of delivery into the fire. Ordinarily, all firefighters regardless of assignment require durable fire recommended eight inch (203 mm) minimum boots, gloves, Nomex pants and shirt, a hard hat, potable water, eye protection and a fire shelter.
In the U.S., a firefighter's credentials and level of training is shown on their red card. For example, a sawyer will have a feller rating on their red card designating the capacity size tree they have been trained to fell. A firefighter trained as an EMT may have this certification on their card. Classes under the National Wildfire Coordinating Group (NWCG) and management qualification standards under the Interagency Fire Program Management (IFPM) are generally shown as well. At a minimum, the passing of the pack test is displayed showing the individual is physically able to perform appropriate duties.
Typically, wildland firefighting organizations will use large handcrews of 20 or more people who travel in vehicles to the fire incident. Although these crews can vary above or below 20 firefighters, they are generally called twenty-man crews. The designations of these crews in the U.S., defined in large portion by training, are as follows:
|Type I Interagency Hotshot Crew|
|Type II Initial Attack (IA) Crew|
|Type II Crew|
|Type III Crew|
Some personnel are organized into fast attack teams typically consisting of five to eight personnel. Similar to the larger crews, they travel by vehicle.
Smokejumpers are highly skilled firefighters specially trained in wildfire suppression tactics. They parachute into remote areas from aircraft to combat wildfires and are equipped to work in remote areas for extended periods of time with little logistical support.
The use of helicopter-delivered fire resources varies by agency. Often, helitack crews perform duties similar to other initial attack crews. Two or three firefighters will be dispatched to a newly reported fire. Helitack crews are usually used for initial attack on fires that are difficult for other firefighters to access, or on extended fires that require aerial support in the form of water drops, cargo delivery, crew shuttling, or reconnaissance. A typical initial attack response by a helitack crew involves flying to the fire via helicopter and spending one to three days (although sometimes much longer) putting the fire out before hiking to the nearest road for pickup.
A highly effective way to fight wilderness fire when no roads are nearby is to have wildland firefighters rappel from a helicopter. These firefighters then take suppressive action on the fire or clear a safe landing zone to receive additional firefighters if the fire is too large. Rappellers usually carry 30 pounds of personal gear plus up to 300 pounds of fire gear which is lowered down to them from their helicopter. Rappelling heights can range from 30 feet (in tall, continuous brush) to 250 feet (in timber). When suppression is complete on rappel fires, ground transport is typically arranged to pick up the firefighters at the nearest road. These crews carry chainsaws, hand tools, radios, and can even have 75-US-gallon (280 L) water bags, known as blivets, flown in to help fight the fire. When not rappelling, the crew works as a helitack crew and can fly or hike to any regular fire.

When water is required to refill a fire engine, water delivery is vital. The typical water tender carries 1,200 US gallons (4,500 L) of water to support fire engines. In addition to supplying fire engines directly, tenders may fill water reservoirs for bucket-dropping helicopters when a lake or reservoir is not nearby.
Heavy equipment's primary function of wildfire suppression is through the application of heavy construction style equipment to move large amounts or earth or remove vegetation. Fuel breaks, safety zones, firelines and access to areas that maybe previously were inaccessible may be made. Bulldozers and tractor plows are examples.
In addition to aircraft being used for deploying ground personnel, firefighting groups may utilize helicopters and fixed-wing airplanes specially equipped for use in aerial firefighting to douse areas that are inaccessible to vehicles with water and/or flame retardant chemicals.
