The storage of flammable liquids in control areas within an S Occupancy (Storage Occupancy) is governed by the 2021 International Fire Code (IFC), Section 5003 – Hazardous Materials, and Table 5003.1.1(1).

IFC Section 5003.1.1(1) – Maximum Allowable Quantity (MAQ) Adjustments:

The maximum allowable quantity (MAQ) of flammable liquids in a control area may be doubled if an approved automatic sprinkler system is installed throughout the building.

Why Other Options Are Incorrect?

A. Permission is granted by the chief.

Fire officials can enforce code requirements but do not have the authority to override MAQ limits unless explicitly allowed in the code.

B. The control area exceeds 50,000 sq. ft.

The code does not specify an increase based solely on size; the sprinkler system is the determining factor.

D. The control area is provided with exhaust ventilation in accordance with fire code requirements.

While ventilation is important for hazardous material safety, it does not allow for an increase in the maximum storage quantity.

✅ Correct Answer: C. The building is protected with automatic sprinklers.
