Fire Suppressant and Retardant Use in the Wildfires. Fire control operations also have the potential to impact park ecosystems (e.g. water withdrawal from streams and lakes, chemical and fuel spills, cat guard construction). Fire suppressants and fire retardants are two categories of fire control requiring special monitoring. A fire retardant is a substance that is used to slow or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion. Fire retardants may also cool the fuel through physical action or endothermic chemical reactions. Fire retardants are available as powder, to be mixed with water, as fire-fighting foams and fire-retardant gels.
Airplanes and helicopters have long worked in concert with ground crews to fight big wildfires. When used effectively, retardant draws a chemical line in the landscape that can keep a fire from Author: William Yardley. Chemical fire retardants are considered a vital wildland firefighting tool, helping to slow the spread of flames while ground crews move into position. But as their use increases, the harmful side effects of these chemicals are coming under increasing scrutiny. The chemicals, usually dropped from low-flying aircraft, largely consist of ammonia compounds, which are Author: Matt Weiser.
Wildland Fire Control. STUDY. PLAY. AERIAL FUELS. A wildland fire that has not been contained or controlled by initial attack forces and for which more firefighting resources are arriving, en route, or being ordered by the initial attack incident commander. A line of water, or water and chemical retardant, sprayed along the ground. Chemical fire retardant compounds are popular in forestry applications and are usually dropped by fixed wing aircraft during wildland fires. These fire retardant chemicals are not intended for.

Long-term fire retardants, commonly referred to as retardants, are applied from aerial or ground equipment. The red liquids dropped from aircraft, often viewed in media coverage of wildland fire-fighting activities, are retardants.
These products, which are primarily the same salts found in fertilizers, are supplied as either wet or dry concentrates. Each long-term retardant product used in wildland fire-fighting is a mixture of individual chemicals.
The product is supplied as a concentrate, in either a wet (liquid) or dry (powder) form, which is then diluted with water to produce the mixture that is applied during fire-fighting operations.

TOXICITY OF FIRE RETARDANT AND FOAM SUPPRESSANT CHEMICALS TO PLANT AND ANIMAL COMMUNITIES Fire retardants and suppressants are used extensively in the United States for suppression and control of range and forest fires.
Each year, fire control agencies utilize millions of gallons of these mixtures on a wide array of ecosystems. Phos-Chek fire retardants are used for wildland fire control in forest, brush or grassland. Functionally, Phos-Chek retardants react with and alter the thermal decomposition of wildland fuels so that they do not support flaming or glowing combustion.
This deprives the fire of fuel, reducing fire intensity and the rate of flame spread. Fire retardancy of wood involves a complex series of simultaneous chemical reactions, the products of which take part in subsequent reactions.
Most fire retardants used for wood increase the dehydration reactions that occur during thermal degradation so that more char and fewer combustible volatiles are Size: KB.

Ensures chemical fire retardants and suppressants are provided to airtanker(s) at the rate specified and for the expected duration. Checks all accessory equipment such as valves, hoses, pumps, and tanks. Takes immediate steps to obtain personnel and equipment to perform operations safely and efficiently.
They combine combustion, flame retardants, smoke and toxic products and material-specific aspects of combustion in relation to textiles, composites, and bulk polymers. The contributors include the latest research in the nanocomposites, making it an essential source for anyone working with, studying, and developing fire retardant s: 2.
Retardants can be dropped from an aircraft to cool a fire and slow its progress long enough for fire fighters on the ground to take action. Retardants are applied to various forest ecosystems during seasonal fire suppression operations to assist in wildland fire suppression efforts, support ground crews, and to protect values across the NWT.

Retardant Crewmember The Retardant Crew Member loads Wildland Fire Chemicals (WFC) into airtankers and reports to the Mix Master (MXMS). The RTCM works in the Air Operations functional area. Aerial firefighting is the use of aircraft and other aerial resources to combat types of aircraft used include fixed-wing aircraft and umpers and rappellers are also classified as aerial firefighters, delivered to the fire by parachute from a variety of fixed-wing aircraft, or rappelling from als used to fight fires may include water, water.
All wildland fire agencies remain committed to wildland fire readiness through active hiring of fire personnel, adjusting training practices to minimize contact and slow COVID spread potential, and assessing prescribed burning operations. All wildland firefighting partners are working together to plan for fire activity during COVID The configuration of some fuels, such as coal and baled waste paper, result in a deep seated and burrowing fire, resulting in less effective fire control by the application of water on the outer surfaces of the fuel.
Some Class-B fires can be controlled with the application of chemical fire. Ground Applied Retardant. PHOS-CHEK® Long-Term Retardant is a valuable fire management tool for controlling and suppressing wildland fires. For over 50 years, PHOS-CHEK has been applied from the air by the world’s largest fire management agencies.
Now Fire Managers are getting great results by applying PHOS-CHEK from the ground. Since the beginning of the s research has been directed towards improving the effectiveness of water as a forest fire extinguishing agent. Throughout this time various chemical substances have been added to the water, and this is still the case today.
Among these substances are the various types of long-term forest fire retardant, which maintain their ability to alter combustion Cited by: personnel, it is acceptable to anchor the wildland fire chemical application.
