Q

What to look for when sizing up a building?

A 
Age of building (weathering or deteriorating)
Construction materials (wood frame, masonry, metal, concrete)
Roof type (arched or lightweight)
Renovations (additions, facades or false ceilings)
Dead loads (HVAC, water tanks or other heavy objects on roof)

Q

Name 6 out of 11 indicators of a potential building collapse.

A
  1. Cracks or separations in walls, floors, ceilings and roof structures.
  2. Evidence of existing instabilities such as tie rods and stars.
  3. Looser missing brick, block or stones.
  4. Deteriorated mortar between the masonry.
  5. Leaning walls.
    6 distorted structural members.
  6. Prolonged fire exposure to the structural members (especially trusses).
  7. Unusual cracks or creaking noises.
  8. Structural members pulling away from walls.
  9. Excessive weight of building contents.
  10. Fire beneath floors that support heavy machinery.
17
Q

What is a lightweight steel truss?

A

Structural support made from a steel bar, bent at a 90 degree angle.

18
Q

What is a lightweight wood truss?

A

2x4 connected with a gusset plate.

19
Q

What is a gusset plate?

A

Metal or wood plates used to connect the intersections of wood or metal components to a load bearing unit.

20
Q

What is a gang nail?

A

A type of gusset plate that have V-shaped holes with prongs to fasten.

21
Q

What is tension?

A

Vertical or horizontal forces that pull things apart.

22
Q

What is compression?

A

Vertical or horizontal forces that push material together.

23
Q

What is a rain roof?

A

A second roof constructed over the top of an older roof.

24
Q

Some examples of why buildings under construction are a hazard would be?

A

Contributing factors are, addition Fire loads and ignition sources, fire repression materials like wall board and sprinklers are not in place, building codes may not be followed.

25
Q

What are the strengths and weaknesses of type 1 (fire-resistive) construction?

A

Strengths
Resists direct flame impingement

Confines fire well

Little collapse potential from the effects of Fire alone

Impervious to water damage

Weaknesses
Difficult to breach entry or escape

Difficult to ventilate

Massive debris after collapse

Floors ceilings and walls retain heat

26
Q

What are the strengths and weaknesses of type 2 (noncombustibles) construction?

A

Strengths
Almost as fire resistant as type 1

Confines fire well

Almost as structurally stable as type 1

Easier to vertically ventilate than type 1

Weaknesses
Difficult to breach for access or escape

Steel structural components can fail due to heat

Roof system less stable than type 1

Steel components subject to weakening by fire

Steel subject to weakening by rust and corrosion

Massive debris after collapse

27
Q

What are the strengths and weaknesses of type 3 (ordinary) construction?

A

Strengths
Resist fire spread from the outside

Relatively easy to vertically ventilate

Weaknesses
Interior structural members vulnerable to fir involvement

Fire spread potential through concealed spaces

Susceptible to water damage

28
Q

What are the strengths and weaknesses of type 4 (heavy timber ) construction?

A

Strengths
Resists collapse due to flame impingement of heavy beams

Structurally stable

Relatively easy to vertically or horizontally ventilate

Relatively easy to breach for access of escape

Manageable debris after collapse

Weaknesses
Susceptible to fire spread from outside

Potential for flame spread to other nearby structures

Susceptible to rapid interior flame spread

Susceptible to water damage

29
Q

What are the strengths and weaknesses of type 5 (wood frame) construction?

A

Strengths
Easily breached for access, Ventilation or escape

Collapse debris relatively easily managed

Weaknesses
Susceptible from fire spread from the outside

Susceptible to rapid flame spread inside

Susceptible to total collapse due to fire or explosions

Susceptible to water damage

30
Q

What actions should be taken when imminent building collapse is suspected?

A

First
Command and all others inside the building should be informed of the situation as you exit.

Second
Clear the collapse zone ASAP

know and heed evacuation signals used by your department

31
Q

What hazards exist with lightweight construction?

A

Lightweight steel, wooden trusses, and gusset plates can fail quickly with no exposure to flame just heat.

32
Q

What hazardous situations may arise from renovated buildings?

A

Concealed spaces created by rain roofs and mansard fascia where fire can spread undetected.
