A 501 gal. water capacity above-ground liquefied petroleum gas (LP-gas) tank located 20 ft. from a 250 gal. LP-gas tank must be separated a minimum of __ ft. from adjoining property.
Correct Answer: B
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.
Question 2
A local board of appeals may perform all of the following functions except:
Correct Answer: A
IFC Section 108 (Board of Appeals) outlines the board's role: it hears appeals on fire code official decisions (Section 108.1), can interpret the code (B), approve alternatives (C) per Section 104.9, and establish procedural rules (D) per Section 108.2. However, the board cannot "waive" code requirements outright (A)- it can only grant variances or approve alternatives that still meet the code's intent, not eliminate requirements entirely. Waiving implies nullification, which exceeds the board's authority; that power rests with the fire code official or legislative amendments. Thus, A is the exception.
Question 3
The minimum working space width for a 66-in. wide electrical equipment panel shall be in
Correct Answer: C
Minimum Working Space Width for Electrical Equipment Panels According to National Electrical Code (NEC) 110.26(A)(2) and International Fire Code (IFC) 2021, Section 604.3, the minimum working space width for electrical equipment must be at least the width of the equipment or 30 inches, whichever is greater. Since the equipment panel in the question is 66 inches wide, the required working space width must be at least 66 inches. 2. Why 66 Inches is the Correct Answer The minimum clearance width must be equal to the width of the electrical equipment if the panel itself is wider than 30 inches. This ensures safe maintenance and emergency access to electrical components. 3. Verification of Other Options Option A (30 inches) - Incorrect, because the equipment is wider than 30 inches, requiring a larger clearance. Option B (36 inches) - Incorrect, as this is not the requirement for a 66-inch-wide panel. Option D (78 inches) - Incorrect, as the clearance does not need to exceed the width of the panel. Reference Sources: National Electrical Code (NEC) 2023 - Section 110.26(A)(2) (Working Space Width Requirements) International Fire Code (IFC) 2021 - Section 604.3 (Electrical Equipment Clearance Requirements) ICC Fire Inspector II Study Guide (2021)
Question 4
A Type I handrail that is not circular shall have a minimum perimeter dimension of ___ inches.
Correct Answer: D
According to the 2021 International Fire Code (IFC) and the International Building Code (IBC) Section 1014.3, handrails are categorized into Type I and Type II based on their shape and size requirements. Type I handrails refer to those that are not circular in shape but still comply with graspability requirements. IBC Section 1014.3.1 states that: If a handrail is not circular, it must have a perimeter dimension between 4 inches (minimum) and 6.25 inches (maximum). The cross-section of such a handrail should provide an adequate grasping surface.
Question 5
Foamed plastics or materials containing foamed plastics used for stage scenery must be approved when tested in accordance with
Correct Answer: A
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.
