International Code Council Fire-Inspector-II Dumps

A container in a clean-agent extinguishing system must be refilled or replaced if it experiences a loss of more than 5% of its original weight or a loss in original pressure of more than 3%. This requirement ensures the system maintains sufficient agent concentration for fire suppression.

Reference to Fire Inspector Documentation:

1. NFPA 2001 – Standard on Clean Agent Fire Extinguishing Systems (2022 Edition)

NFPA 2001, Section 7.3.2.1 states that a container must be refilled or replaced if the weight loss exceeds 5% or the pressure loss exceeds 3% from the original fill pressure.

These limits are set to maintain system effectiveness and ensure that a clean-agent system can properly discharge in case of a fire.

2. 2021 International Fire Code (IFC) – Chapter 9 (Fire Protection Systems)

IFC 904.10 requires that clean-agent systems be maintained per NFPA 2001 to ensure reliability.

Detailed Explanation of Answer Choices:

Option A (Correct): 3% pressure loss is the correct threshold beyond which a container must be replaced or refilled.

Option B (Incorrect): While 5% is correct for weight loss, it is not the correct value for pressure loss.

Option C (Incorrect): A 10% pressure loss is too high and would compromise system performance before reaching the replacement threshold.

Option D (Incorrect): 12% is well beyond the acceptable loss limit and would pose a significant safety risk.

Thus, the correct and verified answer is: A. 3

 Reference to Fire Code Requirements for Clearance Between Combustible Fibers and Sprinklers:

The International Fire Code (IFC 2021), Section 3206.6, states that the minimum clearance between the tops of piles of combustible fibers and sprinkler deflectors shall be no less than 3 feet.

This requirement ensures that the sprinkler system operates efficiently and that water distribution is not obstructed in case of a fire.

 Fire Safety Concerns:

Combustible fibers pose a high fire risk due to their flammability and tendency to generate large amounts of heat and smoke.

Adequate clearance prevents heat accumulation near the sprinkler heads, ensuring they activate at the correct temperature.

 Clarification of Incorrect Answer Choices:

A. 2 ft. → Incorrect

Too low and could obstruct sprinkler operation, reducing water distribution effectiveness.

C. 4 ft. → Incorrect

Exceeds the required minimum per the IFC 3206.6 standard, though more clearance is beneficial.

D. 5 ft. → Incorrect

More than the code requirement, but the mandatory clearance is 3 feet.

 Conclusion:

The correct and verified answer is B (3 feet) based on IFC 3206.6, ensuring proper sprinkler performance and fire safety for combustible fiber storage.

Understanding Construction Types

The International Building Code (IBC) Chapter 6 classifies building construction types based on material combustibility and fire resistance.

Type II construction is noncombustible, meaning it is built using materials such as steel or concrete that do not contribute fuel to a fire.

The difference between Type IIA and Type IIB is the level of fire resistance.

2. Fire Resistance Rating Requirement

Type IIA construction requires a minimum 1-hour fire-resistive rating for structural elements, meeting the conditions in the question.

Type IIB, on the other hand, has no minimum fire-resistive rating for structural components, making it less protective than Type IIA.

3. Verification of Other Options

Option B (IIB) – Incorrect, as Type IIB has no fire-resistive rating for its structural elements and does not meet the 1-hour requirement.

Option C (IIIB) – Incorrect, as Type III allows combustible exterior materials and is not entirely noncombustible.

Option D (VA) – Incorrect, as Type V construction is wood-framed and does not meet the requirement for noncombustible materials.
