The maximum allowable quantity per control area is specified in Tables 5003.1.1(1) through 5003.1.1(4) of the IFC. Tables 5003.1.1(1) through 5003.1.1(4) establish the maximum quantities allowed in a control area (see Section 5003.8.2 for design and protection requirements). If the quantity of chemicals used in a building does NOT exceed the maximum allowed per control area AND the number of control areas does NOT EXCEED the number and percentage of chemicals allowed by Table 5003.8.3.2, those areas are considered part of the main use and do NOT have to meet all of the requirements for a hazardous occupancy.
