How does NFPA 30 address inside container storage ares?

0

Chapter 4 of NFPA 30 describes four types of inside liquid storage areas: inside rooms, which have no exterior walls; cut-off rooms, which have either one or two exterior walls; attached buildings, which share only one wall with another structure; and liquid warehouses, which are either separate buildings entirely or which are separated by 4-hour construction from adjoining areas. Inside rooms are limited to 150 sq. ft., if of 1 hour construction. If of 2-hour construction, they can be as large as 500 sq. ft. Cut-off rooms and attached buildings are limited to 300 sq. ft., if of 1-hour construction, but can be any size desired, if of 2-hour construction. However, NFPA 30 sets a maximum limit on the total quantity of liquid that can be stored in a cut-off room or attached building, in accordance with Table 4-4.4.1, if a fire protection system is not provided or if the fire protection system cannot meet the criteria imposed by Section 4-8 of NFPA 30.
