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. ✅

According to the International Fire Code (IFC) 2021, when specific fire safety requirements are not explicitly provided for in the code, the responsibility to determine the applicable requirements falls upon the Fire Code Official.

Reference from the IFC (2021):

IFC Section 104.1 – General Authority and Responsibilities:

This section explicitly grants the Fire Code Official the authority to interpret the code and determine the necessary safety measures in cases where the code does not provide specific guidance.

It states: "The fire code official is hereby authorized to enforce the provisions of this code and shall have the authority to render interpretations of the code and to adopt policies and procedures in order to clarify the application of its provisions."

IFC Section 104.9 – Alternative Materials and Methods:

This section further supports the authority of the Fire Code Official by allowing them to approve alternative fire safety measures when strict compliance with the code is not feasible.

Why Other Options Are Incorrect?

A. City Manager:

The city manager is responsible for administrative and operational management but does not have the authority to interpret or enforce fire code requirements.

B. Legal Counsel:

Legal counsel provides legal advice but does not have jurisdiction over fire safety code enforcement.

C. Board of Appeals:

The board of appeals reviews disputes and interpretations made by the Fire Code Official, but they do not have primary responsibility for determining applicable fire safety requirements.

Final Conclusion:

The Fire Code Official is the designated authority responsible for interpreting and applying fire safety requirements in situations where the International Fire Code (IFC) does not explicitly provide specific provisions.

 Reference to LP-Gas Tank Separation Requirements:

The International Fire Code (IFC 2021), Table 6104.3, provides minimum separation distances for above-ground LP-gas tanks based on capacity and proximity to each other or property lines.

According to Table 6104.3, for an LP-gas tank with a 501-gallon capacity located near a 250-gallon tank, the required minimum separation distance from adjoining property is 10 feet.

 Why Separation Distance is Important:

LP-gas is highly flammable, and inadequate separation distances increase the risk of fire spread and explosion hazards.

Proper spacing ensures safety for occupants, emergency responders, and nearby properties.

 Clarification of Incorrect Answer Choices:

A. 5 ft. → Incorrect

Too close per IFC 6104.3; does not meet safety requirements.

C. 20 ft. → Incorrect

20 feet is required for larger tanks, but not for the combined 501-gal. and 250-gal. tank setup.

D. 25 ft. → Incorrect

Greater than the required minimum; while more distance is safer, IFC mandates a minimum of 10 feet.

 Conclusion:

The correct and verified answer is B (10 feet) based on IFC 6104.3, ensuring safe LP-gas tank separation from adjoining properties.
