2) The building configuration (joist spaces, vertical shafts, partition walls), determines the path that the heated products of combustion will follow, both horizontally and  .

3) Pulling down ceiling in the room next to a fire can stop the fire's of travel. 

4) In a small confined space, a fire may diminish due to lack of oxygen, however the heat produced will vaporize volatile combustible contents producing a -rich, oxygen poor atmosphere (backdraft). 

5) An increase in temperature will produce an in the volume of gases. 

6) Buildings are not designed to withstand pressures.

7) The temperatures that precede a flashover make human occupancy dangerous without protective gear.

8) Warning signs of flashover include:  a thick layer of smoke/hot and rising temperatures.

9) Low ceilings, small rooms/compartments, and well-insulated walls or building construction tend to promote .

10) Well-insulated buildings tend to retain heat and redirect it to the building .

11) Sparks can ignite a light fuel in the presence of .

12) Fire grows and spreads dependent on the amount of and oxygen.

13) Backdrafts can create internal capable of internal damage.
