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. ✅

Paint Spray Booth Clearance Requirements

According to the International Fire Code (IFC) 2021, Section 2404.3.2, paint spray booths must have a minimum clearance of 18 inches from unprotected combustible materials.

This clearance requirement helps prevent heat transfer, fire spread, and ignition of nearby combustible materials due to the operation of the spray booth.

2. Why 18 Inches is the Correct Answer

Spray booths generate overspray, vapors, and heat, making clearance essential for fire prevention.

The requirement applies to combustible walls, ceilings, and storage materials surrounding the spray booth.

If combustibles are within 18 inches, additional fire protection such as fire-rated barriers or sprinkler protection may be required.

3. Verification of Other Options

Option A (12 inches) – Incorrect, as the IFC mandates a minimum 18-inch clearance.

Option C (24 inches) – Exceeds the standard clearance requirement but is not the official minimum. Incorrect.

Option D (36 inches) – Some jurisdictions may require larger clearances, but IFC mandates 18 inches as the minimum. Incorrect.

Thus, the correct and verified answer is: B. 18 inche

A code official may allow the occupant load to exceed the building code requirements if additional exit facilities are provided, all egress requirements are met, and the maximum occupancy does not exceed one occupant per 10 sq. ft. of occupiable floor area.

Reference to Fire Inspector Documentation:

1. 2021 International Building Code (IBC) – Table 1004.5 (Occupant Load Factor)

The minimum safe occupancy load factor is 10 sq. ft. per occupant, meaning no space can have more than 1 person per 10 sq. ft.

Fire code officials can approve increased occupancy only if extra exits are provided, ensuring compliance with egress and fire safety rules.

2. 2021 International Fire Code (IFC) – Section 1004.2 (Increased Occupant Load Allowance)

Allows for an increased occupant load only if additional exits and egress requirements are met but never beyond 1 person per 10 sq. ft.

Detailed Explanation of Answer Choices:

Option A (Incorrect): 1 occupant per 3 sq. ft. is too high and would violate egress safety regulations.

Option B (Incorrect): 1 occupant per 5 sq. ft. still exceeds safety limits.

Option C (Incorrect): 1 occupant per 7 sq. ft. is not the minimum required standard.

Option D (Correct): 1 occupant per 10 sq. ft. is the minimum limit for allowing an increased occupant load under IFC 1004.2 and IBC Table 1004.5.

Thus, the correct and verified answer is: D. 10.
