Question 11

When fighting a fire in an apartment building, whats one thing that can be done to assist in fire attack?

Answer 11

Quick look at the layout of the apartment directly below.

Question 12

What must be done prior to entry when the fire is in the decay stage? Why?

Answer 12

Vertical Ventilation

In the smoldering phase, all that is needed for fire to free burn violently is introduction of oxygen. Vertically venting allows gases to escape through vertical opening.

Answer 23

Autoextension

Question 24

The movement of heat and smoke from higher air pressure within a fire building to all other lower air pressure areas, both within and outside the fire building.

Answer 24

Flow path

Question 25

At a minimum, ladders should be extended where?

Answer 25

to each floor on which fire fighters are operating.

Ideally, on each side of the building
