Fire-Inspector-II Exam Dumps - International Code Council Fire Inspector Questions and Answers

IFC Section 3103.8.2 (Separation of Temporary Tents) requires tents larger than 15,000 sq. ft. to be separated by at least 20 feet to prevent fire spread, unless connected by a corridor meeting specific requirements (not indicated here). Each tent at 20,000 sq. ft. exceeds this threshold, necessitating 20 feet of separation. Option A (0 ft.) applies only to smaller tents, B (10 ft.) is insufficient, and D (25 ft.) exceeds the minimum. Thus, C is correct.

 Reference to Halon 1211 Hand-Hose-Line System Requirements:

NFPA 12A (Standard on Halon 1211 Fire Extinguishing Systems), Section 6.5, states that all hoses for high-pressure Halon 1211 hand-hose-line systems must be tested at 1,500 psi to ensure they can withstand operational pressure without failure.

The International Fire Code (IFC 2021), Section 904.10, also references the requirements for Halon 1211 systems, ensuring proper testing for system integrity.

 Purpose of Pressure Testing:

High-pressure Halon 1211 systems operate under significant force, and hose failures could result in loss of fire suppression capability or safety hazards.

Testing at 1,500 psi ensures hoses can handle peak pressures without rupture or degradation over time.

 Clarification of Incorrect Answer Choices:

A. 600 psi → Incorrect

Too low for high-pressure systems, insufficient to verify hose integrity.

B. 900 psi → Incorrect

Below the required 1,500 psi standard for high-pressure Halon 1211 hoses.

D. 2,500 psi → Incorrect

Exceeds the required test pressure per NFPA 12A; unnecessary over-testing could damage hoses.

 Conclusion:

The correct and verified answer is C (1,500 psi) based on NFPA 12A and IFC 904.10, ensuring compliance with Halon 1211 high-pressure system testing standards.

Pressure tests for organic coating process piping are required to ensure system integrity and prevent leaks, which could lead to fire or explosion hazards. The minimum required duration for these pressure tests is 1 hour.

Reference to Fire Inspector Documentation:

1. 2021 International Fire Code (IFC) – Section 1504.6.3 (Pressure Testing for Organic Coating Process Piping)

IFC 1504.6.3 mandates that all process piping associated with organic coating operations must undergo a pressure test for at least 1 hour. This ensures that the pipes can handle operational pressures without failure.

2. NFPA 33 – Standard for Spray Application Using Flammable or Combustible Materials (2021 Edition)

NFPA 33, Section 14.2.6 confirms that process piping must be pressure-tested for no less than 1 hour to verify its safety and reliability.

Detailed Explanation of Answer Choices:

Option A (Incorrect): 30 minutes is insufficient for proper pressure testing.

Option B (Incorrect): 45 minutes is still below the 1-hour minimum requirement.

Option C (Correct): 1 hour is the correct minimum test duration as required by IFC 1504.6.3 and NFPA 33.

Option D (Incorrect): 2 hours is longer than required, but the minimum requirement is 1 hour.

Thus, the correct and verified answer is: C. 1 hour.

 Reference to Flammable Liquids Storage Cabinet Requirements:

According to The International Fire Code (IFC 2021), Section 5704.3.2 and NFPA 30 (Flammable and Combustible Liquids Code), Section 9.5.3, the maximum amount of Class II and Class III liquids that can be stored in a flammable liquids storage cabinet is 120 gallons.

This limit ensures safe containment, fire protection, and reduced risk of liquid ignition or spillage.

 Understanding Class II and III Liquids:

Class II liquids: Flash point between 100°F and 140°F (e.g., diesel fuel, kerosene).

Class III liquids: Flash point above 140°F (e.g., motor oil, cooking oils).

While these liquids are less volatile than Class I liquids, they still pose a fire risk, requiring proper storage in approved cabinets.

 Clarification of Incorrect Answer Choices:

A. 10 gallons → Incorrect

Too low; IFC and NFPA allow up to 120 gallons in storage cabinets.

B. 60 gallons → Incorrect

This is the maximum for Class I liquids, but Class II and III liquids are allowed up to 120 gallons.

D. 240 gallons → Incorrect

Exceeds the allowable limit per IFC 5704.3.2 and NFPA 30, which set the maximum at 120 gallons per cabinet.

 Conclusion:

The correct and verified answer is C (120 gallons) as per IFC 5704.3.2 and NFPA 30, ensuring compliance with flammable liquids storage safety standards.

To determine the maximum occupant load for a bowling center with 25 lanes and 3,500 sq. ft. of additional area, we use the occupant load factor from 2021 IBC Table 1004.5.

Step 1: Calculate the Occupant Load for Bowling Lanes

IBC Table 1004.5 assigns 50 sq. ft. per person for bowling lanes and associated seating areas.

With 25 lanes, assuming 100 sq. ft. per lane (standard industry measurement for lane width and approach area):

25×(10050)=25×2=50 occupants25 \times \left( \frac{100}{50} \right) = 25 \times 2 = 50 \text{ occupants}25×(50100​)=25×2=50 occupants

Step 2: Calculate the Occupant Load for Additional Area

Additional 3,500 sq. ft. area follows a general occupant load factor of 15 sq. ft. per person (assembly without fixed seats):

3,50015=233.3 occupants≈234 (rounded)\frac{3,500}{15} = 233.3 \text{ occupants} \approx 234 \text{ (rounded)}153,500​=233.3 occupants≈234 (rounded)

Final Calculation:

50+184=234 occupants50 + 184 = 234 \text{ occupants}50+184=234 occupants

Reference to Fire Inspector Documentation:

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

Bowling lanes require 50 sq. ft. per person.

Assembly areas without fixed seats use 15 sq. ft. per person.

2. 2021 International Fire Code (IFC) – Section 1004.1.2 (Areas without Fixed Seating)

When calculating occupant load, areas without fixed seating must be divided by the appropriate occupant load factor.

Detailed Explanation of Answer Choices:

Option A (Incorrect): 125 is too low based on correct load factor calculations.

Option B (Correct): 234 is the correct calculation using IBC Table 1004.5.

Option C (Incorrect): 500 is too high based on the available space.

Option D (Incorrect): 625 significantly overestimates the actual occupant load.

Thus, the correct and verified answer is: B. 234.

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.
