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. ✅

The storage of flammable liquids in control areas within an S Occupancy (Storage Occupancy) is governed by the 2021 International Fire Code (IFC), Section 5003 – Hazardous Materials, and Table 5003.1.1(1).

IFC Section 5003.1.1(1) – Maximum Allowable Quantity (MAQ) Adjustments:

The maximum allowable quantity (MAQ) of flammable liquids in a control area may be doubled if an approved automatic sprinkler system is installed throughout the building.

Why Other Options Are Incorrect?

A. Permission is granted by the chief.

Fire officials can enforce code requirements but do not have the authority to override MAQ limits unless explicitly allowed in the code.

B. The control area exceeds 50,000 sq. ft.

The code does not specify an increase based solely on size; the sprinkler system is the determining factor.

D. The control area is provided with exhaust ventilation in accordance with fire code requirements.

While ventilation is important for hazardous material safety, it does not allow for an increase in the maximum storage quantity.

✅ Correct Answer: C. The building is protected with automatic sprinklers.

Definition of Extra-High-Rack Combustible Storage

According to International Fire Code (IFC) 2021, Section 3206.6, extra-high-rack combustible storage is defined as:

Class I, II, III, or IV commodities stored on racks exceeding 40 feet in height.

High-hazard commodities stored on racks exceeding 30 feet in height.

2. Understanding Rack Storage Classifications

Class I-IV Commodities: These refer to general, moderate-risk combustible materials such as wood, paper, and plastics.

High-Hazard Commodities: These are materials that have a higher fire risk, such as highly combustible plastics, flammable solids, and products prone to rapid heat release.

3. Verification of Other Options

Option A (20; 30) – Incorrect, as 40 feet is the correct threshold for Class I-IV commodities.

Option B (30; 40) – Incorrect, as 30 feet applies to high-hazard commodities, not Class I-IV commodities.

Option D (50; 40) – Incorrect, as the correct heights are 40 feet and 30 feet, respectively.
