maintained.

EXCEPTION 2: In an industrial occupancy that is

protected by an automatic fire sprinkler system, the

number of cabinets can be increased to 6 in a group.

EXCEPTION 3: In a laboratory fire area, the number

of flammable liquid storage cabinets is not limited;

however, the total quantity of flammable and

combustible liquids is limited to the quantities as

Numerous types of storage areas (e.g., cutoff storage rooms, mercantile storage areas, inside storage rooms, etc.)

can exist. Storage limits for laboratories have been defined in 4.3.14. There are many other types of storage areas

and limits for each of these are not included in this document. A fire protection engineer should be consulted to

determine storage limits for these other storage areas.
