What are the 3 tactics for wildland suppression?

The methods of attack are direct, parallel, and indirect. Direct attack is made directly on the fire’s edge or perimeter (see Figure 3). The flames may be knocked down by dirt or water and the fire edge is generally treated by a follow-up fireline.

What technique is used in fighting wildfires?

Fire lines often are constructed using hoe dads, shovels, or bulldozers. A prescribed burn is another method, also called a burn out. Aerial support is another tactic. Helicopters and air tanks dump fire retardants on the landscape to establish fire lines and protect structures, not to extinguish flames.

Is wildland firefighting bad for your lungs?

These findings suggest that wildland firefighters should reduce exposure to smoke in any way possible.

What is the best strategy firefighters can use to try to slow the spread of a fire?

Firefighters control a fire’s spread (or put it out) by removing one of the three ingredients fire needs to burn: heat, oxygen, or fuel. They remove heat by applying water or fire retardant on the ground (using pumps or special wildland fire engines) or by air (using helicopters/airplanes).

What is cold trailing?

Cold Trailing: A method of controlling a partly dead fire edge by carefully inspecting and feeling with the hand for heat to detect any fire, digging out every live spot, and trenching any live edge.

What does the T in S facts stand for?

S: Survival. F: Fire environment. A: Access. C: Construction/clearance. T: Time.

What are the 3 methods of extinguishing a fire?

The basic methods for extinguishing a fire are to suffocate it by ensuring that it cannot have access to oxygen, to cool it with a liquid such as water which reduces the heat or finally to remove the fuel or oxygen source, effectively removing one of the three elements of fire.

What are fixed fire fighting equipment?

There are a number of fixed fire-fighting facilities available, including:

• fire hydrants and rising mains.
• hose reel systems.
• sprinkler systems.
• water mist and fogging systems.
• gas systems (sometimes referred to as “clean agent systems”)
• foam systems.
• dry powder.

Why do wildland firefighters not wear masks?
