International Fire Code (IFC) 2021 - Section 3313.1 (Temporary Standpipe Requirements for Construction) NFPA 14: Standard for the Installation of Standpipes and Hose Systems ICC Fire Inspector II Study Guide (2021) Thus, the correct and verified answer is: D. 75 feet. #
NEW QUESTION # 53
Which of the following situations requires securing of an operational permit from the code official prior to commencing the related activity?
- A. Organic coating production facility producing 2 gallons per day.
- B. Storing 85,000 bd. ft. of lumber.
- C. Inside storage of 100 cu. ft. of baled cotton.
- D. Fruit ripening operations using carbon dioxide gas.
Answer: B
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.
