• True

• False

Which of the following common building materials performs well under fire conditions but can lose strength through spalling?

• Gypsum

• Lath and Plaster

• Reinforced Concrete

• Composite Material

Which of the following construction types is considered to be the most collapse resistant?

• Type I

• Type II

• Type IV

• Type V

Noncombustible construction as defined by the National Building Code of Canada achieves fire safety by:

• using fire-resistant materials.

• avoiding concealed spaces under floors and roofs.

• placing limitations on sizes of wood structural methods.

• using noncombustible materials for structural members and other building assemblies.

What building component supports only its own weight and may divide two areas within a structure?

• Non-load-bearing wall

• load-bearing wall

• pitched roof

• flat roof

Which of the following styles of roof construction has a large surface-area-to-mass ratios that lead to poor performance under fire conditions?

• Heavytimber or Mill Construction

• Lightweight Truss Construction

• Cast-in Place Concrete

• Field-Framing rafters and ridge beams or ridge poles

Which of the following is MOST likely an indicator of a building collapse?

• Single room fire

• light smoke conditions

• non-protected structural steel

• leaning exterior walls

What building material when heated, loses its strength and expands (lengthens)?

• Cast Iron

• Steel

• Masonry

• Wood

What is an example of a non-combustible (Type II) building?

• A high rise building with all structural components having a fire rated protection

• A commercial building with concrete exterior walls and exposed steel joists

• A warehouse with all structural members being made of large dimension timber

• A private dwelling with all structural components made of wood materials

Which of the following choices BEST represents the parts of a truss?
