1- On floor, on side storage less than 12 ft (3.66 m) in height, or

The purpose of this standard is to provide a reasonable degree of protection for life and property from fire through standardization of design, installat

requirements for sprinkler systems based upon sound engineering principles, test data, and field experience. This standard endeavors to continue the

that has been established by sprinkler systems while meeting the needs of changing technology. Nothing in this standard is intended to restrict new te

alternate arrangements, provided the level of safety prescribed by this standard is not lowered. Materials or devices not specifically designated by thi

be utilized in complete accord with all conditions, requirements, and limitations of their listings.

This standard provides the minimum requirements for the design and installation of automatic fire sprinkler systems and exposure protection sprinkle

Exception No. 1: Wooden pallets stored up to 6 ft (1.8 m) in height or plastic pallets up to 4 ft (1.2 m) in height with not over four stacks o

pallets or two stacks of plastic pallets separated from other stacks by at least an 8-ft (2.4-m) aisle. (For heights or quantities exceeding th

NFPA 231, Standard for General Storage.)

Exception No. 2*: Storage of rubber tires that is incidental to the main use of the building and not more than 2,000 ft2

Occupancy examples in the listings as shown in the various hazard classifications are intended to

represent the norm for those occupancy types. Unusual or abnormal fuel loadings or combustiblecharacteristics and susceptibility for changes in these characteristics, for a particular occupancy, are

considerations that should be weighed in the selection and classification.

present and has combustible interiors),
