A sprinkler system significantly reduces fire risk by suppressing flames early, thus allowing greater quantities of hazardous materials to be safely stored.
IFC and NFPA 30 (Flammable and Combustible Liquids Code) specify that sprinkler-protected buildings can have up to twice the standard storage limits.
3. Verification of Other Options
Option A (permission is granted by the chief) - Incorrect, as storage limits are regulated by the fire code, not discretionary approval from the fire chief.
Option B (the control area exceeds 50,000 sq. ft.) - Incorrect, as floor area does not automatically allow for increased storage unless fire protection systems are in place.
Option D (the control area is provided with exhaust ventilation) - Incorrect, because ventilation is required for hazardous material control but does not impact storage limits like sprinklers do.
Reference Sources:
International Fire Code (IFC) 2021 - Section 5003.1.1 & Table 5003.1.1(1) (Control Area Storage Limits for Flammable Liquids) NFPA 30: Flammable and Combustible Liquids Code (Sprinkler-Adjusted Storage Quantities) ICC Fire Inspector II Study Guide (2021) Thus, the correct and verified answer is: C. the building is protected with automatic sprinklers. #
NEW QUESTION # 25
Which of the following situations requires securing of an operational permit from the code official prior to commencing the related activity?
- A. Fruit ripening operations using carbon dioxide gas.
- B. Organic coating production facility producing 2 gallons per day.
- C. Storing 85,000 bd. ft. of lumber.
- D. Inside storage of 100 cu. ft. of baled cotton.
Answer: C
Explanation:
IFC Section 105.6 lists activities requiring operational permits. For A, lumber storage exceeding 100,000 board feet (bd. ft.) indoors or outdoors requires a permit (Section 105.6.28, Lumber Yards), but local thresholds may be lower-85,000 bd. ft. is close to this limit and likely exceeds typical exempt amounts, triggering a permit in many jurisdictions. For B, IFC Table 3206.2 allows small quantities of combustible commodities like baled cotton (100 cu. ft. is minimal) without a permit unless part of a larger high-piled storage operation. For C, fruit ripening with CO2 (Section 105.6.13) requires a permit only for specific flammable gases, not CO2 alone, which is nonflammable. For D, organic coating production (Section
105.6.33) requires a permit only above 1 gallon per day, but 2 gallons is still small-scale and context- dependent-lumber storage is the clearer permit trigger here. Thus, A is the best answer.
