Important NFPA CFPS Exam Questions

Answer: D

Answer: D

Answer: B

Explanation:

Fire tests typically relate to two types of fire properties, fire resistance and reaction to fire. Fire resistance is the ability of a building element or component to prevent the passage of heat and flames from one side to another, while reaction to fire is the response of a material or product in contributing to the development and spread of a fire. Fire resistance tests are usually performed on systems or assemblies, such as walls, floors, doors, or windows, while reaction to fire tests are usually performed on materials or products, such as sealants, insulation, cladding, or plastics.

Answer: C

Explanation:

The use of an exhaust to an abatement system during the large-scale tests made the test results difficult to interpret for use in field applications. The exhaust system was used to reduce the environmental impact of the tests, but it also altered the natural buoyancy-driven flow of the smoke and heat through the vents and draft curtains. This created a pressure difference between the inside and outside of the test building, which affected the performance of the sprinklers, vents, and draft curtains. Therefore, the test results may not accurately reflect the conditions that would occur in real buildings without an exhaust system.

Answer: A

Explanation:

The correct answer is A. Type I construction consists of structural members of approved noncombustible or limited combustible materials with specified fire resistance ratings for exterior bearing walls of 3 or 4 hours. This is the highest level of fire resistance among the five types of construction defined by NFPA 220: Standard for Types of Building Construction. Type I construction is typically used for high-rise buildings made of concrete and protected steel12
