They are responsible for removing heat, smoke, and gases to allow greater visibility and permit engine company personnel to move rapidly and safely within a fire building or exposure buildings




providing access to and exits from all parts of the building

*Ladder company operations may either accompany or precede engine company operations.




true / false

true


Ladder company operations may either accompany or precede engine company operations.

Fire resistive construction is intended to_____________________

Fire resistive construction is intended to confine the convection cycle to one floor or to a small area of a floor in any type of building.

*Proper ventilation is a huge help against concentrations of radiant heat.


t/f




explain

false


Proper ventilation is of LITTLE help against concentrations of radiant heat.




Venting will remove the smoke, hot air, and heated gases, thereby lessening the chance of rapid spread and flashover, but the radiant heat remains and must be counteracted through proper application of water on the seat of the fire itself

Fuel and oxygen are typically scarce in supply. If the fire burns unchecked, heat continues to build up and allow the fire to enhance in size and intensity.




t/f

false


Fuel and oxygen are typically plentiful in supply. If the fire burns unchecked, heat continues to build up and allow the fire to enhance in size and intensity.
