Exam 7: Fire and Smoke-Related Properties

What is the type of construction of the building of Problem 8 if the floor's fire rating is 2 h, while all else remain unchanged?

Describe what constitutes active fire protection in buildings.

Explain the term "fire area."

The building codes permit the use of fire- retardant- treated (FRT)wood or FRT plywood in some situations where noncombustible materials are required, although both these materials are not recognized by codes as noncombustible materials. Explain the reasons.

The International Building Code classifies interior finishes as Class A, Class B, and Class C. Which material property(ies)are these classes based on?

Combustible types of construction are

Explain the differences between the automatic sprinkler systems: NFPA 13, NFPA 13R, and NFPA 13D.

The exit access corridor walls in most occupancies need not be fire rated if the building is provided with automatic sprinklers throughout.

Which type of construction is commonly used for single- family dwellings in the U.S.?

Is the fire rating of non- load- bearing walls (i.e., partition walls)a determinant for the type of construction of a building?

The exterior walls of a building may pose a fire hazard to the adjacent building within the same lot or across the property line. Therefore, an exterior wall's minimum required fire rating is a function of its distance from the adjacent building, defined as fire separation distance (FSD)by the International Building Code. What is the required minimum value of FSD for a non- load- bearing wall (such as a glass curtain wall)so that the wall's fire rating may be zero?

Give one example where fire- retardant- treated (FRT)wood or FRT plywood is permitted by the codes as substitute for noncombustible materials.

The International Building Code classifies types of construction into three groups based on the requirement for the use of combustible or noncombustible materials. What is the requirement for the noncombustible/combustible group?

Discuss the differences between a fire code and a building code.

Fire- resistance rating of building assemblies is generally obtained from fire tests, not through calculations.

The fire code is one of the most important chapters in a building code.

List the factors that affect fire safety in buildings.

A material whose core is noncombustible but is covered with a combustible lamination or paint is considered a noncombustible material, provided that the thickness of the paint or lamination does not exceed

Name the quantity that measures the fire endurance of an assembly and give its units.

The fire properties that determine the class of interior finishes are
