Exceptions: The maximum allowable quantity per control area requirements set forth in FC Tables 5003.1.1(1) through 5003.1.1(4) shall not apply to:

1. A construction site in an unoccupied building prior to issuance of a certificate of occupancy or temporary certificate of occupancy for such building. Maximum allowable quantity per control area requirements shall apply to a construction site in an occupied or partially occupied building, except as may be otherwise authorized by the department in writing.

2. Liquid or gaseous fuel in fuel tanks on motor vehicles.

3. Gaseous fuels in piping systems and fixed appliances regulated by the Fuel Gas Code.

4. Liquid fuels in piping systems and fixed appliances regulated by the Mechanical Code.

5003.1.2 Conversion.

A conversion factor of 10 pounds per gallon (1.2 kg/L) shall be used to ascertain the weight per gallon of liquid when such weight is not provided or otherwise available to the commissioner.

5003.1.3 Quantities not exceeding the maximum allowable quantity per control area.

The storage, handling and use of hazardous materials in quantities not exceeding the maximum allowable quantity per control area indicated in FC Tables 5003.1.1(1) through 5003.1.1(4) shall be in accordance with FC 5001 and 5003.

5003.1.4 Quantities exceeding the maximum allowable quantity per control area.

The storage, handling and use of hazardous materials in quantities exceeding the maximum allowable quantity per control area indicated in FC Tables 5003.1.1(1) through 5003.1.1(4) shall be in accordance with this chapter and, in a high-hazard occupancy, the requirements of the Building Code.

5003.1.5 Additional specific requirements.

The storage, handling and use of hazardous materials shall additionally comply with the specific requirements of FC Chapters 51 through 67, as applicable.
