International Code Council Fire-Inspector-II Exam With Confidence Using Practice Dumps

 Reference to Automatic Sprinkler Requirements:

The International Fire Code (IFC 2021), Section 903.2.11.1 and NFPA 13 (Standard for Installation of Sprinkler Systems) regulate when sprinkler systems are required based on ventilation and fire spread potential.

A building with only one exterior wall providing openings creates a fire trap, increasing the need for automatic sprinklers.

 Determining the Required Distance:

IFC 903.2.11.1 states that when the wall opposite the provided openings is more than 100 feet away, an automatic sprinkler system must be installed to ensure proper fire suppression.

 Clarification of Incorrect Answer Choices:

A. 50 ft. → Incorrect

Sprinklers are not necessarily required at this distance because natural ventilation is still effective.

B. 75 ft. → Incorrect

This distance still allows some natural ventilation, making sprinklers optional rather than mandatory.

D. 150 ft. → Incorrect

Sprinklers are required once the distance exceeds 100 feet, so waiting until 150 feet would not meet code requirements.

 Conclusion:

The correct and verified answer is C (100 feet) based on IFC 903.2.11.1 and NFPA 13, ensuring fire safety in office buildings with limited exterior openings.

Understanding Type III Construction

According to the International Building Code (IBC) 2021, Section 602.3, Type III construction is a mix of noncombustible and combustible materials.

Exterior walls must be noncombustible or fire-retardant-treated wood, while interior structural elements (such as floors, roofs, and partitions) can be wood.

2. Common Uses of Type III Construction

Churches, schools, apartment buildings, and mercantile (retail) structures are often built using Type III construction because it balances fire resistance with cost-effectiveness.

Many low-rise residential and commercial buildings use this type due to its ability to support multiple stories while maintaining some fire protection.

3. Verification of Other Options

Option A (Type I) – Incorrect, as Type I construction is entirely noncombustible (steel/concrete) and used for high-rises, not typical for churches, schools, or apartments.

Option B (Type II) – Incorrect, as Type II construction is fully noncombustible but has lower fire resistance than Type I, mainly used for commercial buildings, warehouses, and low-rise offices.

Option D (Type IV) – Incorrect, as Type IV (heavy timber) is rarely used for schools and apartments, though some older churches may use it.

Thus, the correct and verified answer is: C. Type III. ✅

For Group I-2 occupancies (such as hospitals, nursing homes, and similar healthcare facilities), horizontal exits are used to improve fire safety by allowing occupants to move to a safer area without using stairs or elevators.

IFC 2021, Section 1026.1 (Horizontal Exits – General Requirements) states that:

Horizontal exits shall not comprise more than one-half (1/2) of the required exits from any floor area in a Group I-2 occupancy.

This ensures that at least 50% of the required exits remain traditional vertical or exterior exits, maintaining a balance between horizontal and traditional egress routes.

✅ Correct Answer: B. 1/2
