NEW QUESTION # 23
In mass timber construction of Type IV-B, each of the following is suitable for use as fireblocking except:
Answer: A
Explanation:
A 7/16-inch wood structural panel is not one of the prescriptively acceptable fireblocking materials listed by IBC Section 718.2.1. Therefore, option C is correct.
Section 718.2.1 permits fireblocking to consist of several specified materials. These include one-half-inch gypsum board; properly secured batts or blankets of mineral wool, mineral fiber, or other approved materials; and mass timber complying with Section 2304.11. Options A, B, and D are consequently valid.
For wood structural panels, however, the IBC requires a substantially greater thickness: a single thickness of approximately 0.719 inch , conventionally represented as 23/32 inch, with joints backed by material of the same required thickness. A 7/16-inch panel is only approximately 0.438 inch thick and therefore does not satisfy that prescriptive fireblocking provision.
Fireblocking is intended to interrupt concealed draft openings and restrict the movement of flame and hot gases through concealed combustible spaces. It should not be confused with a tested firestop system used at penetrations through fire-resistance-rated assemblies.
Special inspection should confirm that the installed material, thickness, joint backing, retention, and location conform to the approved construction documents and the applicable code provision.

NEW QUESTION # 24
Refer to the figure by clicking on the EXHIBIT button above.
In Type IV-B construction, unprotected portions of mass timber as shown in the Figure are required to be separated by _____ feet.
Answer: D
Explanation:
The required separation is 15 feet , making option B correct. Section 602.4.2.2.4 of the 2021 IBC specifically regulates the separation distance between unprotected mass timber elements in Type IV-B construction.
Within each dwelling unit or fire area, unprotected portions of mass timber walls and ceilings must be separated from other unprotected wall and ceiling portions by not less than 15 feet . For ceiling-related surfaces, the separation is measured horizontally along the ceiling. For wall-to-wall exposure, the applicable separation is measured horizontally along the floor.
This requirement operates in addition to the maximum exposed-area restrictions. A designer therefore cannot merely demonstrate that the exposed ceiling is below 20 percent or that exposed walls are below 40 percent of floor area; the exposed regions must also satisfy the required spatial separation.
The purpose is to prevent multiple exposed mass timber regions from acting as closely spaced fuel packages during a compartment fire. During inspection, dimensions should be checked against the approved documents before required gypsum or other noncombustible protection is completed.

NEW QUESTION # 25
What fire-resistance rating is required for floors in Type IV-A, IV-B and IV-C construction?
Answer: A
Explanation:
IBC Table 601 requires floor construction and associated secondary structural members in Types IV-A, IV-B, and IV-C construction to have a two-hour fire-resistance rating. Therefore, option B is correct.
This requirement applies to the complete floor assembly, not only the timber panel. The required two-hour performance may be established through the calculated fire resistance of the mass timber, the contribution of approved noncombustible protection, or a permitted combination of both. Any topping, protective membrane, connection protection, and edge condition that forms part of the approved rated design must be installed accordingly.
The ratings for other building elements should not be transferred to the floor. A three-hour rating applies to the primary structural frame and bearing walls of Type IV-A, but its floor construction remains two hours.
Type IV-B and Type IV-C floors also require two hours, even though those construction types permit different degrees of exposed mass timber.
The special inspector must verify panel dimensions, approved layup, protection layers, joints, penetrations, connections, topping thickness, and other details that influence the floor's rated performance.
References/Topics: 2021 IBC Sections 601 and 602.4; Table 601, floor construction and associated secondary structural members.
NEW QUESTION # 26
According to UL Fire Resistance Directory, a "finish rating" is the time:
Answer: D
Explanation:
Option C correctly states the fundamental UL finish-rating criterion. UL defines a finish rating for assemblies containing combustible wood structural supports as the elapsed fire-exposure time at which the wood member immediately behind the protective membrane reaches the prescribed temperature-rise threshold.
More precisely, UL uses two criteria: an average temperature rise of 250°F or an individual-point temperature rise of 325°F , measured on the plane of the wood nearest the fire, typically between the gypsum membrane and the wood stud or joist. The question asks for the principal definition, which is the 250° F temperature-rise criterion; therefore, option C is correct. Option D incorrectly treats the 325°F individual- point limit as the sole definition.
Options A and B confuse a finish rating with "assigned protection time." IBC Tables 722.6 and 722.7 provide calculated contribution values for specified protective materials, but those assigned values are not themselves UL finish ratings.
This distinction matters in mass timber fire design because membrane contribution, thermal separation, structural fire resistance, and finish rating are related but not interchangeable concepts.

325°F temperature-rise criteria.
NEW QUESTION # 27
The maximum allowable height for a Group I-4 building of Type IV-B construction provided with an automatic sprinkler system in accordance with Section 903.3.1.1 is _____ ft.
Answer: D
Explanation:
The applicable requirement is found in 2021 IBC Section 504.3 and Table 504.3. The table regulates building height in feet above grade plane by occupancy, construction type, and sprinkler condition. For a Group I-4 occupancy equipped throughout with a Section 903.3.1.1 sprinkler system, the applicable row is the sprinklered "S" row.
Reading across that row to Type IV-B construction gives a maximum building height of 120 feet. Therefore, option B is correct. The 180-foot value applies to Type IV-A construction for the same occupancy and sprinkler condition. The 85-foot value, which is not offered, applies to Type IV-C and Type IV-HT. The 270- foot value generally appears for certain lower-hazard occupancies-such as Groups A, B, E, F, M, S and U- when constructed as sprinklered Type IV-A, but it is not permitted for Group I-4.
This distinction reflects the additional life-safety considerations associated with custodial-care occupancies. A special inspector should verify that the approved construction documents identify both the correct occupancy classification and construction type because either classification directly changes the permitted height.
