3 building, Construction: fire, fighting problems, and structural hazards

Question 1

List five basic construction types, when considering collapse, or the fire resistance of a building

Answer 1

These are:
I - fire-resistive construction
II - Noncombustible/limited combustible construction
III - ordinary brick and Joist construction
IV - heavy timber construction
V - wood frame construction

Question 2

What is the major fire problem in a high-rise fire resistive building?

Answer 2

The fire problem in a high- rise fire resistive building is the central air conditioning system.

Question 3

What is the fire problem associated with a non-combustible/limited combustible building

Answer 3

A problem associated with a non-combustible and limited combustible building is the flat, combustible asphalt roof deck covering. When a fire occurs in a non-combustible, limited, combustible building, as soon as possible after the fire is dark and down. Check the roof covering above.

Question 4

Question 6

In an ordinary construction fire firefighters must be directed to…

Answer 6

Open the ceiling above the fire and nearby wall to examine for fire spread

Question 7

What is the major fire problem of a heavy timber construction?

Answer 7

The major fire problem of a heavy timber type IV construction is the large, wooden interior timber framework. Each interior wood structure member must meet size specifications.
- Wood columns cannot be less than 8 inches thick in any dimension
-Wood girders cannot be less than 6 inches thick 

Question 8

Which of the five types of construction have combustible exterior walls?

Answer 8
