Flammable Liquid Storage Limits in Control Areas
According to the International Fire Code (IFC) 2021, Section 5003.1.1 and Table 5003.1.1(1), the allowable quantity of flammable liquids stored in a control area can be doubled if the building is equipped with an automatic sprinkler system that complies with NFPA 13.
2. Why Automatic Sprinklers Allow Increased Storage
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.

Thus, the correct and verified answer is: C. the building is protected with automatic sprinklers. ✅
