? Reference to Occupant Load Calculation:

The International Fire Code (IFC 2021), Section 1004.2 states that the calculated occupant load of a building may be increased if all other life safety provisions are met.

However, the occupant load cannot exceed one person per 5 square feet when increased beyond the standard calculations.

? Fire Safety Considerations for Increased Occupant Load:

Increasing the occupant load requires ensuring:

Egress capacity (number and width of exits) meets the increased load.

Fire protection systems (sprinklers, alarms, etc.) are adequate for the new load.

Proper ventilation and sanitation facilities are maintained.

IFC 1004.2 and NFPA 101 both enforce the maximum limit of 1 occupant per 5 square feet in modified occupant load scenarios.

? Clarification of Incorrect Answer Choices:

A. 3 sq. ft. ? Incorrect

Too small for safe egress and occupant movement; the code does not allow such high density in general occupancies.

C. 7 sq. ft. ? Incorrect

While some occupancies have higher space-per-occupant allowances, 5 sq. ft. is the maximum density permitted when increasing load.

D. 15 sq. ft. ? Incorrect

15 sq. ft. per person is for lower-density assembly and business occupancies, not for maximum occupant load increases.

? Conclusion:

The correct and verified answer is B (5 sq. ft. per occupant) as per IFC 1004.2 and NFPA 101, which govern occupant load increases in buildings.

? Reference to ICC Fire Code Regulations:

According to the International Fire Code (IFC) Section 308.1.5 (2021 Edition), the use of open-flame devices, including candles, is prohibited in dormitories, sleeping rooms, and similar occupancies unless specifically approved by the fire code official.

The regulation exists to prevent fire hazards in areas with high occupant density and potentially limited egress routes.

? Fire Safety Concerns in Dormitories:

Dormitories typically contain highly combustible materials such as bedding, curtains, and furniture, making them susceptible to rapid fire spread.

The presence of multiple residents in a shared living space increases the risk of fire-related casualties.

Even in sprinklered buildings, candles pose an unnecessary ignition risk that could endanger occupants before the activation of fire suppression systems.

? Clarification of Incorrect Answer Choices:

B. may be used in a sprinklered dormitory ? Incorrect

While fire sprinklers help control fires, they do not prevent ignition, and the prohibition still applies regardless of sprinkler systems.

C. must be kept a minimum of 12 inches from combustibles ? Incorrect

This rule applies to general open-flame devices in some circumstances but does not override the outright ban on candles in dormitories.

D. must be kept a minimum of 36 inches from combustibles ? Incorrect

Similar to option C, maintaining a distance from combustibles does not exempt candles from being prohibited in dormitory settings.

? Conclusion:

The correct and verified answer is A (Candles may not be used) based on the International Fire Code (IFC) Section 308.1.5, ensuring fire safety compliance in dormitory settings.

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.

? Correct Answer: D. 6.25 inches

LP-Gas Storage Limits for Dealers in Non-Public Buildings

According to the International Fire Code (IFC) 2021, Section 6109.9, the maximum allowable quantity of LP-gas in containers stored by a dealer awaiting resale in a building that is not open to the public is 2,000 pounds of water capacity.

This limit is intended to reduce fire and explosion hazards in enclosed spaces while allowing reasonable storage for commercial purposes.

2. Understanding Water Capacity vs. Propane Weight

The water capacity of an LP-gas cylinder refers to the total weight of water the container can hold, not the actual propane content.

The propane content is typically about 42% of the water capacity (i.e., 2,000 lbs. of water capacity is approximately 840 lbs. of propane).

3. Verification of Other Options

Option A (735 lbs.) – Incorrect, as IFC allows a significantly higher storage limit for dealers in non-public buildings.

Option B (1,000 lbs.) – Incorrect, as the actual limit per IFC 6109.9 is 2,000 lbs.

Option D (2,500 lbs.) – Incorrect, as this exceeds the IFC's maximum allowable storage limit.

ICC Fire Inspector II Study Guide (2021)

Battery-charging areas for industrial trucks (such as forklifts) present a fire hazard due to the potential for flammable hydrogen gas buildup and electrical malfunctions. To mitigate this risk, portable fire extinguishers with a minimum rating of 40-B:C are required.

Reference to Fire Inspector Documentation:

1. 2021 International Fire Code (IFC) – Section 309.5 (Fire Extinguishers for Battery-Charging Areas)

IFC 309.5 states that battery-charging areas must have a portable fire extinguisher with a minimum rating of 40-B:C to handle potential electrical and flammable liquid fires.

The B rating covers flammable liquid fires (such as battery electrolyte leaks), while the C rating ensures it is safe for electrical fires.

2. NFPA 10 – Standard for Portable Fire Extinguishers (2022 Edition)

NFPA 10, Table 6.3.1.1 outlines that industrial battery-charging areas must have at least one extinguisher rated 40-B:C.

This ensures adequate fire suppression capability for both electrical and flammable liquid hazards.

Detailed Explanation of Answer Choices:

Option A (Incorrect): 4-A:20-B:C includes a higher A-rating (for ordinary combustibles), but 20-B:C is below the required 40-B:C.

Option B (Incorrect): 3-A:40-B:C exceeds the B:C requirements but adds an unnecessary A-rating, which is not specified in the code.

Option C (Incorrect): 2-A:10-B:C is insufficient, as it does not meet the 40-B:C minimum requirement.

Option D (Correct): 40-B:C is the correct and minimum required rating per IFC 309.5 and NFPA 10.

Thus, the correct and verified answer is: D. 40-B:C.
