How do you contain fire?
Controlling a fire means ensuring that the fire can’t spread or cross the containment line. That means putting up barriers, removing or burning any fuel that could help the fire spread, and cooling any hot spots – those are especially active parts of the fire that could suddenly jump.
Can you fight fire with fire?
Fire can be used to fight forest fires, albeit with a certain amount of risk. A controlled burn of a strip of forest will create a barrier to an oncoming forest fire as it will use up all the available fuel.
Can fire ever beat water?
Fire will scorch the surface quickly, but water, with time, will cut through solid rock. Also, water can put out a fire and the best the fire can do is turn the water into its gaseous form – but it just changes the form of the water, it doesn’t destroy it.
What is the golden rule for tackling a fire?
Only tackle a fire when it is in its very early stages. Give consideration to your own safety and the safety of other people and make sure you can escape from the fire if you need to. Never let a fire block your exit. Think about the position of yourself, the fire and the escape route.
What is direct attack in fire?
Any treatment applied directly to burning fuel such as wetting, smothering, or chemically quenching the fire or by physically separating the burning from unburned fuel.
What are the four main techniques involved in firefighting?
The acronym PASS is used to describe these four basic steps.
- Pull (Pin) Pull pin at the top of the extinguisher, breaking the seal.
- Aim. Approach the fire standing at a safe distance.
- Squeeze. Squeeze the handles together to discharge the extinguishing agent inside.
- Sweep.
What is direct attack?
DEFINITIONS AND PROCEDURES. Generally a direct attack is an effort prior to conclusion of the appeal or as an alternative to an appeal, to reform or set aside a judgment within the original action. A collateral attack is a new action or original action filed to attack a prior judgment.
What is the difference between a direct attack and an indirect attack?
A direct attack occurs when an attacker tries to flood a victim with a stream of packets directly from the attacker’s computer. An indirect attack tries to flood the victim computer in the same way, but the attacker’s IP address is spoofed (i.e., faked) and the attack appears to come from another computer.
What are the advantages of indirect attack?
Indirect attack takes advantage of using natural and human-made barriers as fireline and allows a choice of timing for backfiring. Indirect attack is generally used on hot fires with high rates of spread where direct attack is not possible.
What is the objective of an indirect fire attack?
An indirect attack (used when a room’s interior has been heated to the point that it is nearing a flashover condition). Fire fighters first use an indirect attack method to cool the fire gases down to safer temperatures and prevent flashover from occurring.
What is a parallel attack?
Method of fire suppression in which fireline is constructed approximately parallel to, and just far enough from the fire edge to enable workers and equipment to work effectively, though the fireline may be shortened by cutting across unburned fingers.
What is the most common type of wildland fire?
What is the most common type of wildland fire? Ground cover: fires that burn loose debris on the surface of the ground. This debris includes vegetation such as grass, as well as dead leaves, needles, and branches that have fallen from shrubs and trees.
What is an indirect fire line?
Indirect Line – Fireline placed a distance away from the fire edge. Mop Up –After an area has burned, extinguishing or removing burning material near control lines, felling snags and trenching logs to prevent rolling, to make a fire safe, or to reduce residual smoke.
What is the area where human development meets with the wildland?
WUI
Why are wildland-urban interface fires becoming more frequent and more costly?
The reasons wildland fires on federal lands have become expensive and dangerous include: A build-up of fuels resulting in part from past fire suppression policies, 1. A warming climate, including drought in the West, and 2. The development of homes adjacent to fire-prone public lands.
What is a wildland area?
The wildland–urban interface (WUI) is a zone of transition between wilderness (unoccupied land) and land developed by human activity – an area where a built environment meets or intermingles with a natural environment. Human settlements in the WUI are at a greater risk of catastrophic wildfire.
What does Wui mean?
wildland-urban interface
What is Wui in California?
Most California Fires Occur in Area of Wildland-urban Interface with Less Fuel and More People. “Intermix” WUI, on the other hand, is defined as the area where houses and wildland vegetation directly intermingle.

What is an urban interface fire?
The wildland-urban interface (WUI), defined as the area where houses are in or near wildland vegetation, is the area where wildfires pose the greatest risk to people due to the proximity of flammable vegetation (1). Wildfires frequently burn houses in the WUI (2, 3), and are most difficult to fight there.
