International Code Council Fire-Inspector-II Dumps

 Reference to Automatic Sprinkler Requirements:

The International Fire Code (IFC 2021), Section 903.2.11.1 and NFPA 13 (Standard for Installation of Sprinkler Systems) regulate when sprinkler systems are required based on ventilation and fire spread potential.

A building with only one exterior wall providing openings creates a fire trap, increasing the need for automatic sprinklers.

 Determining the Required Distance:

IFC 903.2.11.1 states that when the wall opposite the provided openings is more than 100 feet away, an automatic sprinkler system must be installed to ensure proper fire suppression.

 Clarification of Incorrect Answer Choices:

A. 50 ft. → Incorrect

Sprinklers are not necessarily required at this distance because natural ventilation is still effective.

B. 75 ft. → Incorrect

This distance still allows some natural ventilation, making sprinklers optional rather than mandatory.

D. 150 ft. → Incorrect

Sprinklers are required once the distance exceeds 100 feet, so waiting until 150 feet would not meet code requirements.

 Conclusion:

The correct and verified answer is C (100 feet) based on IFC 903.2.11.1 and NFPA 13, ensuring fire safety in office buildings with limited exterior openings.

IFC Section 903.3.5 and Appendix B (Fire-Flow Requirements) allow a reduction in fire flow when sprinklers are installed. For a Type II-B building (noncombustible, unprotected), the base fire flow (7,000 gpm) reflects a large, unsprinklered structure (e.g., per Table B105.1(2)). With full sprinkler protection, IFC B105.2 permits a reduction to as low as 25% of the original flow or the sprinkler demand (whichever is greater), typically 1,500 gpm for commercial buildings per NFPA 13 standards, assuming adequate water supply. Options B, C, and D exceed this minimum without justification. Thus, A is correct.

Foamed plastics or materials containing foamed plastics used for stage scenery must meet strict fire performance requirements to prevent rapid flame spread and fire hazards in assembly occupancies.

The correct fire test standard for these materials is UL 1975 – Standard for Fire Tests for Foamed Plastics Used for Decorative Purposes.

Reference to Fire Inspector Documentation:

1. 2021 International Fire Code (IFC) – Section 807.4.2 (Foamed Plastics for Stage Scenery)

IFC 807.4.2 states that foamed plastics used in scenery must be tested and approved per UL 1975 to ensure fire safety.

2. UL 1975 – Standard for Fire Tests for Foamed Plastics Used for Decorative Purposes

This standard evaluates the flammability and smoke production of foamed plastics used in decorative applications, including stage scenery.

Detailed Explanation of Answer Choices:

Option A (Correct): UL 1975 is the required test standard for foamed plastics used in stage scenery, ensuring compliance with IFC 807.4.2.

Option B (Incorrect): NFPA 11A deals with foam-water fire suppression systems, not foamed plastics for decorative use.

Option C (Incorrect): CPSC 16CFR relates to consumer product safety regulations but does not address fire safety for foamed plastics on stage scenery.

Option D (Incorrect): ASTM D 1784 is a test for rigid PVC plastics and does not apply to foamed plastics used for stage scenery.

Thus, the correct and verified answer is: A. UL 1975.
