BUILDING COLLAPSE
Test Questions
| Question | Answer |
|---|---|
| ch1. Burning bulding collapse is the fourth leading cause of fireground death at 7.4% | ch1. Falls, falling abjects and contact with objects is second leading cause of fireground death 27% |
| ch1. NFPA states physical stress is #1 cause of fireground death 42% | ch1. Exposure to fire product is #3 cause of fireground death at 18% |
| ch1. three factors that will increase the number of structural collapse 1. age 2. abandonment 3. lightweight construction materials | ch1. a building has a life span of 75-100 yrs. |
| ch1. A building vacant for several years,exposed to rain, snow, summer heat, and freezing temperatures, will collapse more quickly during a fire than will occupied buildings. | ch1. The use of lightweight construction materials in the Sun Belt and western states presents another serious danger to the future firefighters of America. |
| ch1. One reason for the lack of collapse studies is that any research into the subject offers small benefit to anyone except firefighters. | ch1. Outside impartial investigators, who were operating at the fire scene at the time of the collapse and who can objectively evaluate the collapse rubble, are necessary in order to conduct an analysis of the incident. |
| ch1. The NFPA states, "Structural collapse means that a major integral part of a structure failsed as a result of fire" | ch1. The term structural collapse is defined as "any portion of a structure that fails as a result of fire." |
| ch1. The final and most important reason for the abscenece of collapse information for FF after 200 yrs. of firefighting experience is the lack of fire department documentation and record of collapse. | ch1. when a burning building collapse kills or seriously injures a FF, a post-investigation and analysis should be conducted. |
| ch2. ARCH: a curved structure used as a support over an open space. The removal or destruction of any part of an arch will cause the entire arch to collapse | ch2. BALLOON CONST: One of the 3 basic methods of constructing wood frame residential buildings (brace frame & platform are the other two) |
| ch2. If a non-bearing wall collapses during a fire, the continuous studs will cause the wall to fall straight outward in one section, at 90 degree angle. | ch2. If the bearing wall of a balloon constructed building fails, it can cause a second collapse of the floors it supports. |
| ch2. BEAMS: A beam is a horizontal structural member, subject to compression, tension, and shear, supported by one of three methods- Cantilever, Continuous, & Simple. | ch2. Examples of Cantilever structures are an ornamental stone cornice, a marquee, a canopy, a fire escape and an advertising sign. |
| ch2. Continuous beam support: A beam supported at both ends and at the center. | ch2. BRACED-FRAME CONST.: one of the 3 basic methods of wood frame residential buildings (balloon & platform are the other two) it is sometimes referred to as Post-and-Girt construction. |
| ch2. During a fire a braced-frame building wall often fails in an inward/outward collapse | ch2. BUTTRESS: A wall reinforcement or brace built on the outside of a structure, sometimes called a "wall column" |
| ch2. On a masonry wall , a buttress is a column of bricks built into the wall. When seperated from the wall and connected by an arch at the top, it is called a flying buttress. | ch2. The presence of a buttress on an exterior wall can indicate the point where roof trusses or girders are supported by a bearing wall. |
| ch2. A buttress constructed on the inside of a wall is called a pilaster | ch2. Collapse: The failure of any portion of a structure during a fire. |
| ch2. Curtain-Fall Wall Collapse: One of the three types of masonry wall collapse, it occurs when an exterior masonry wall drops like a falling curtain cut loose at the top. | ch2. The impact of an aerial platform master stream striking a veneer wall at close range can cause a curtain-fall collapse of bricks. |
| ch2. Inward/Outward Collapse: The collapse of an exterior wall that breaks apart horizontally. The top collapses inward, back on top of the structur; the bottom collapses outward on to the street. | ch2. Inward/Outward Collapse: Wood braced-frame constructed buildings collapse in this manner, and a timber truss roof collapse can cause a secondary collpase of a front wall in this manner. |
| ch2. Lean-Over Collapse: A type of wood-frame building collapse indicated by the burning structure slowly starting to tilt or lean over to one side. | ch2. Lean-to Floor Collapse: A floor collapse in which one end of the floor beams remains partially supported by the bearing wall, and the other end of the floor beams collapse on to the floor below or collapses but remains unsupported. |
| ch2. A Lean-to Collapse can be classified as supported or unsupported, depending upon the position of the collapsed beam ends. |
