STAGES OF FIRE

What are the stages of fire in the modern fire development curve?

A

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

46
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE

DESCRIPTION OF MODERN FIRE STAGES BY THE BOOK -

A
  • 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.
47
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

Definition of the incipient stage of fire:

A

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

48
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

Definition of the growth stage of fire:

A

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.

49
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

What is an indication that conditions in a fire area are rapidly changing?

A

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.

50
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

When does flashover occur?

A

Between the growth stage and the fully developed stage

51
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

What is the definition of the fully developed stage?

A

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

52
Q

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.

A

TRUE

53
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

What is the definition of the decay stage?

A

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.

54
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

How does backdraft occur?

A

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.

55
Q

ENGINE OPS 4 - FIRE SCENE OPERATIONS
STAGES OF FIRE DEVELOPMENT

Signs of backdraft?

A
  • Reversal of air
  • Glass windows stained with smoke condensation and pulsating from the pressure of the fire.
