Answer 44

Incipient Growth Fully developed Decay

Question 45

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE What are the stages of fire in the modern fire development curve?

Answer 45

Incipient Rapid growth Early oxygen limited decay stage If oxygen introduced a 2nd rapid growth stage may be encountered (transitioning to a fully developed) Second decay stage will occur as fuel depleted or fire extinguished

Question 46

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DESCRIPTION OF MODERN FIRE STAGES BY THE BOOK -

Answer 46

- Incipient. - rapid growth stage that consumes the available oxygen very quickly. - Since modern content fires rapidly consume the available oxygen within the fire area, they enter into an earlier oxygen limited Decay stage when compared to Legacy Fires, and will remain in the Decay Stage if no additional oxygen is added to the fire area. - If additional oxygen is added to the fire area, a second rapid growth stage may be encountered. - A second decay stage will occur as the fuel load is depleted or the fire is extinguished.

Question 47

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT Definition of the incipient stage of fire:

Answer 47

The early stage of fire development where the fire's progression is limited to a fuel source and the thermal hazard is localized to the area of the burning object

Question 48

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT Definition of the growth stage of fire:

Answer 48

Growth: The stage of fire development when the heat release rate from an incipient fire has increased to the point where heat transfers from the fire and causes the combustion products to pyrolyze adjacent fuel sources.

Question 49

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT What is an indication that conditions in a fire area are rapidly changing?

Answer 49

ROLLOVER **rollover is an indicator that fire conditions are rapidly changing. When rollover is observed and members are not operating under the protection of a charged hoseline, they shall immediately leave and isolate the fire area. As the fire continues to progress towards the fully developed stage, the potential for a flashover exists.**

Question 50

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT When does flashover occur?

Answer 50

Between the growth stage and the fully developed stage

Question 51

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT What is the definition of the fully developed stage?

Answer 51

The stage of fire development which has reached its peak heat release within a compartment. This usually occurs after flashover.

Question 52

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT TRUE/FALSE As modern content fires rapidly consume the available oxygen, the fire can go into an early decay stage prior to reaching full development. The interior conditions are pre-heated, smoke filled and oxygen deficient. As additional oxygen is added to the interior, a ventilation induced flashover can occur, resulting in rapid fire development.

Answer 52

TRUE

Question 53

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT What is the definition of the decay stage?

Answer 53

Decay: The stage of fire development within a structure characterized by either a decrease in the fuel load or available oxygen to support combustion, resulting in lower pressure and lower temperatures in the fire area.

Question 54

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT How does backdraft occur?

Answer 54

When a supply of oxygen is introduced and mixes with the flammable gases, an explosive event (deflagration) can occur. The gases can ignite and develop into a backdraft with explosive force.

Question 55

ENGINE OPS 4 - FIRE SCENE OPERATIONS STAGES OF FIRE DEVELOPMENT Signs of backdraft?

Answer 55

- Reversal of air - Glass windows stained with smoke condensation and pulsating from the pressure of the fire. - Dense black, dirty brown, yellow brown and gray yellow smoke

Answer 71

FALSE When rollover is observed and members are not operating under the protection of a charged hoseline, they shall immediately leave and isolate the fire area. As the fire continues to progress towards the fully developed stage, the potential for a flashover exists. Flashover causes the fire to spread rapidly through the space, resulting in fire involvement of the entire compartment or enclosed space.
