How the fire was initially ignited

14. Which of the following statements about fire-retardant treatments for wood is MOST accurate?

Treatments only provide protection for 3-5 years.

Treatments must be reapplied every year for maximum effectiveness.

Treatments do not affect the structural strength regardless of weather conditions.

Treatments may adversely affect structural strength as a result of elevated temperature and humidity.

15. The two main methods of fire-retardant treatment of wood are pressure impregnation and:

aging.

dipping.

surface coating.

flash treatment.

16. During a fire, the behavior of building materials is affected by their chemical and physical properties and:

initial cost.

method of fabrication.

manufacturer markings.

distance to smoke detection systems.

17. Which of the following statements about plastics is MOST accurate?

They are used infrequently in both building exteriors and interiors.

They are not usually used for structural applications in buildings.

It is not viable to incorporate or add fire retardants to any plastics.

The use of plastics has no impact on the fire hazards of a building.

18. Which of the following statements about siding is MOST accurate?

All siding must be noncombustible.

All siding is considered combustible.

Buildings are allowed only one layer of siding.

Older buildings may have multiple layers of siding.

Fully tempered

20. Which of the following joints hold laminated members together?

Hip joints

Scarf joints

Collar joints

Secondary joints

21. Modern synthetic building wraps are much:

less fire resistant than felt or tar paper.

more fire resistant than felt or tar paper.

more prone to degradation than felt or tar paper.

more expensive and time consuming to install than felt or tar paper.

22. Which construction material is required by the International Building Code® to be graded (labeled) to denote strength?

Members have significantly stronger load capacities than solid wood

Sizes and shapes can be produced that are not available from solid wood

29. Which of the following statements about gypsum board is MOST accurate?

It must be sprayed with a finishing spray for any fire resistive properties.

It is used mainly for aesthetics and provides little protection to components.

High water content gives it excellent heat-resistant and fire-retardant properties.

It breaks down quickly under fire conditions and cannot be used in fire-resistive semblies.
