Fire behavior includes such things as how fast a fire burns (rate of spread), how hot it burns (fire intensity), the presence of fire whirls, and ember production and spotting..

What are the 3 major factors in wildfire behavior?

Many factors govern a wildfires’ behavior. The three sides of the fire behavior triangle are weather, topography and fuels. Weather includes wind, temperature, cloudiness, moisture and air pressure. High temperatures and low humidity cause vegetation to dry and wildfires to burn rapidly.

What is the most dangerous part of a fire?

Error. Something went wrong. MEMPHIS, TN (WMC) – The fire that killed nine people Monday morning only burned 25 percent of the home, but the smoke filled the entire building, according to Memphis Fire Department.

What is dangerous fire behavior?

A low concentration of oxygen will slow the burning right down. An example of dangerous fire behaviour that can occur in a situation where there is a low concentration of oxygen is called backdraught. This is when an enclosed fire has used up most of the oxygen and is just smouldering.

What are the 5 stages of fire?

These stages are incipient, growth, fully developed, and decay. The following is a brief overview of each stage.

What determines fire behavior?

Weather conditions such as wind, temperature, and humidity also contribute to fire behavior. … Humidity, the amount of water vapor in the air, affects the moisture level of a fuel. At low humidity levels, fuels become dry and, therefore, catch fire more easily and burn more quickly than when humidity levels are high.

What are the 7 factors that affect fire development?

Interior finish in a room, fuel continuity, feedback, material ignitability, thermal inertia of the fuel, proximity of flames to walls are the major factors that influence fire growth.

What are the 3 stages of a fire?

Stages of fireIgnition: Fuel, oxygen and heat join together in a sustained chemical reaction. … Growth: With the initial flame as a heat source, additional fuel ignites. … Fully developed: Fire has spread over much if not all the available fuel; temperatures reach their peak, resulting in heat damage.More items…

What is the most common fire?

How can Backdraft be prevented?

If backdraft conditions are suspected, proper ventilation will prevent the explosion. Openings must be made above the fire to allow the superheated gases to escape before oxygen is introduced at lower levels-the lower levels where we would be entering. Backdrafts and flashovers are equally dynamic and deadly.

How do you detect a fire?

Optical smoke detectors are generally quick in detecting slow-burning, smoky fires. Ionization detectors are sometimes known as an ionization chamber smoke detector (ICSD), which is capable of quickly sensing flaming fires that produce little smoke.
