Reference to Fire Code Requirements for Clearance Between Combustible Fibers and Sprinklers:
The International Fire Code (IFC 2021), Section 3206.6, states that the minimum clearance between the tops of piles of combustible fibers and sprinkler deflectors shall be no less than 3 feet.
This requirement ensures that the sprinkler system operates efficiently and that water distribution is not obstructed in case of a fire.
Fire Safety Concerns:
Combustible fibers pose a high fire risk due to their flammability and tendency to generate large amounts of heat and smoke.
Adequate clearance prevents heat accumulation near the sprinkler heads, ensuring they activate at the correct temperature.
Clarification of Incorrect Answer Choices:
A: 2 ft. # Incorrect
Too low and could obstruct sprinkler operation, reducing water distribution effectiveness.
C: 4 ft. # Incorrect
Exceeds the required minimum per the IFC 3206.6 standard, though more clearance is beneficial.
D: 5 ft. # Incorrect
More than the code requirement, but the mandatory clearance is 3 feet.
Conclusion:
The correct and verified answer is B (3 feet) based on IFC 3206.6, ensuring proper sprinkler performance and fire safety for combustible fiber storage.
