1. A
Type II-B construction for Group B occupancy without sprinklers has a maximum building height of 55 feet per IBC Table 504.3. This height limitation is based on the noncombustible materials used in Type II construction and the moderate fire load of business occupancies.

2. A
Group M (Mercantile) classification applies to buildings used for display and sale of merchandise regardless of occupant load. The 500-person threshold does not change the occupancy classification; it only affects certain code requirements within that classification.

3. B
According to IBC Section 1005.1, egress components must have a minimum width of 44 inches when serving an occupant load of 50 or more. For occupant loads of 200, the calculated width may be larger, but 44 inches is the minimum standard width required.

4. A
IBC Table 1017.2 specifies a maximum travel distance of 200 feet for unsprinklered Group B occupancies. This distance is measured from any occupied point to the nearest exit along the natural path of travel.

5. C
Per IBC Section 1007.1.1, when two exits are required, they must be placed at a distance apart not less than one-third of the length of the maximum overall diagonal dimension of the area served. This is reduced to one-quarter in fully sprinklered buildings.

6. B
According to IBC Table 601, Type I-A construction requires a minimum 3-hour fire-resistance rating for the building’s structural frame, bearing walls, and floor construction, representing the highest level of fire protection.

7. D
IBC Section 803.11 restricts interior finishes in exit enclosures to Class A or Class B materials. Class C and Class D materials are not permitted in these critical egress components due to their higher flame spread characteristics.

8. C
Per IBC Section 1011.5.2, the maximum riser height for stairways is 7.75 inches (7-3/4 inches). This dimension provides a balance between code compliance and comfortable stair ascent.

9. B
According to IBC Section 403.1, a high-rise building is defined as a building with an occupied floor located more than 75 feet above the lowest level of fire department vehicle access, triggering special fire and life safety requirements.

10. A
IBC Section 1003.2 requires a minimum headroom of 6 feet 8 inches (80 inches) in means of egress. This minimum applies to corridors, stairs, and other egress components measured from the floor to the lowest projection.

11. B
Group I-2 includes hospitals, nursing homes, and similar facilities where occupants are incapable of self-preservation due to medical conditions. Group I-1 is for supervised residential facilities, and Group I-3 is for detention facilities.

12. A
Per IBC Table 506.2, an unsprinklered Group A-2 occupancy in Type II-B construction is limited to 9,500 square feet per fire area. This limitation accounts for the assembly use and construction type fire resistance.

13. B
IBC Section 1011.5.2 requires a minimum tread depth of 11 inches for stairs in the means of egress. This dimension ensures adequate foot placement for safe stair navigation during both normal use and emergency evacuation.

14. A
Per IBC Table 509, boiler rooms exceeding 15 psi require either 1-hour fire barrier separation with automatic sprinklers or 2-hour fire barrier separation without sprinklers. This protects adjacent areas from potential boiler hazards.

15. C
The IBC only recognizes Type I-A and Type I-B as Type I construction categories. There is no Type I-C designation in the code. Type I construction is noncombustible with the highest fire-resistance ratings.

16. B
According to IBC Section 713.4, shaft enclosures connecting four or more stories require a minimum 2-hour fire-resistance rating. Shafts connecting less than four stories require a minimum 1-hour rating.

17. B
Per IBC Table 1006.2.1, the maximum common path of egress travel in a sprinklered Group B occupancy is 100 feet. This is an increase from the 75-foot limit for unsprinklered buildings.

18. C
IBC Section 1020.2 requires a minimum corridor width of 96 inches (8 feet) in Group I-2 occupancies where beds are moved. This accommodates the movement of patient beds during normal operations and emergencies.

19. B
Group I-4 occupancy classification applies to daycare facilities providing care to more than five children 2.5 years of age or younger. These facilities require enhanced supervision and safety features for this vulnerable population.

20. B
Per IBC Section 505.2, a mezzanine must not exceed one-third of the floor area of the room or space in which it is located to not be considered a story. Exceeding this limit would classify it as an additional story.

21. B
According to IBC Table 722.1, floor assemblies separating dwelling units in Group R-2 occupancies require a minimum 1-hour fire-resistance rating to provide adequate protection between residential units.

22. B
Per IBC Table 1004.5, assembly areas with fixed seats calculate occupant load based on the actual number of fixed seats installed. This provides an accurate count rather than an area-based calculation.

23. B
IBC Section 1020.4 permits a maximum dead-end corridor length of 50 feet in sprinklered Group B occupancies. This is an increase from the 20-foot limit in unsprinklered buildings.

24. B
According to IBC Section 1010.1.1, the minimum clear width of means of egress doors is 32 inches measured with the door in the 90-degree open position. The door leaf itself must be at least 36 inches wide.

25. B
Per IBC Table 602, exterior walls of Type II-A construction located 5 feet from a property line require a minimum 1-hour fire-resistance rating. Walls closer than 5 feet may require higher ratings.

26. B
According to IBC Section 403.4.5, high-rise buildings are required to have a fire command center. This dedicated room serves as the location for fire department operations during emergencies.

27. B
Per IBC Section 716.3, fire-rated glazing in door assemblies is limited to a maximum of 1,296 square inches when installed with a fire-protective rating that matches the door rating.

28. B
IBC Section 1010.1.6 requires a minimum landing length of 44 inches in the direction of travel. This provides adequate space for door swing and occupant movement at door locations.

29. C
According to IBC Section 1012.2 and accessibility requirements, the maximum slope for an accessible ramp is 1:12 (one unit of vertical rise for every 12 units of horizontal run), or 8.33 percent.

30. B
Per IBC Section 1026.2, horizontal exits require a minimum 2-hour fire-resistance rating. This ensures the fire barrier provides adequate protection for occupants moving from one fire area to another.

31. C
Group B occupancy applies to eating and drinking establishments with an occupant load of less than 50. Bars and taverns with 50 or more occupants are classified as Group A-2.

32. B
According to IBC Section 1010.1.9.2 referencing accessibility standards, door hardware must be installed between 34 inches and 48 inches above the finished floor to be accessible.

33. B
Per IBC Section 506.3, buildings with frontage on public ways or open spaces may increase the allowable floor area by up to 75 percent based on the extent of the building perimeter that has such frontage.

34. B
According to IBC Table 601, Type III-A construction requires exterior walls with a minimum 2-hour fire-resistance rating. Type III construction allows combustible interior elements but requires noncombustible or fire-rated exterior walls.

35. B
Per IBC Section 716.2, fire-protective glazing in 1-hour rated corridor walls requires a minimum 45-minute fire protection rating. This includes sidelights adjacent to exit doors.

36. A
According to IBC Table 1006.3.4, a single exit from a Group B occupancy story above the level of exit discharge is permitted when the occupant load does not exceed 29 occupants.

37. B
Per IBC Section 1208.2, the minimum ceiling height in habitable rooms is 7 feet 6 inches (90 inches). This applies to all areas intended for human occupancy except bathrooms and kitchens.

38. B
Type IV construction, also known as heavy timber construction, requires structural elements of heavy timber with minimum dimensions specified in the code. Light-frame wood is not permitted for structural elements.

39. C
According to IBC Section 407.5.1, smoke barriers in Group I-2 occupancies require a minimum 1-hour fire-resistance rating. These barriers create smoke compartments for patient protection.

40. C
Per IBC Table 504.4, Type V-B construction for Group R-2 occupancy with sprinkler protection is limited to a maximum of 4 stories. Without sprinklers, this would be limited to 2 stories.
