Also referred to as air attack. The use of aircraft in support of ground resources to combat wildfires, often most effective in initial attack in light fuels. air drop The delivery of supplies or fire retardant from the air. Supplies can be dropped by parachute, while retardant is generally released in a single drop of one or more trails, the size of which is determined by the wind and the ...
A controlled burn or prescribed burn (Rx burn) is the practice of intentionally setting a fire to change the assemblage of vegetation and decaying material in a landscape. The purpose could be for forest management , ecological restoration , land clearing or wildfire fuel management.
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.
By the 1980s, in light of this new understanding, funding efforts began to support prescribed burning in order to prevent wildfire events. [3] In 2001, the United States implemented a National Fire Plan, increasing the budget for the reduction of hazardous fuels from $108 million in 2000 to $401 million. [4]
A backfire is a more aggressive type of burning done to influence the behavior of the main fire. In forest and prairie management, the driptorch is the most common tool used to ignite prescribed burns, which are used to remove excess fuel buildup or to re-create natural cycles of fire in an ecosystem.
The Joint Code of Practice provides advice on how to prevent fires such as through the use of flame-retardant temporary protection materials: for example, some high quality floor protectors are designed to burn slowly and prevent the spread of fires.
Ruggedized infrared equipment used by some firefighters to detect hidden people, animals, heat sources (i.e., fire) and structural compromise. Tones A series of two or three musical notes, used as an auditory alert over a radio or radio-paging system to indicate that a particular fire company, district, or territory is dispatched to service on ...
Broadcast burning is commonly used to prepare clearcut sites for planting, e.g., in central British Columbia, [26] and in the temperate region of North America generally. [27] Prescribed burning is carried out primarily for slash hazard reduction and to improve site conditions for regeneration; all or some of the following benefits may accrue:
