12.2.1 Small hose connections [11⁄2 in. (38 mm)] shall be provided where required by the authority having jurisdiction in accordance with 8.17.5 for first-aid fire-fighting and overhaul operations.

12.2.2 Small hose connections shall not be required for the protection of Class I, II, III, and IV commodities stored 12 ft (3.7 m) or less in height.

8.17.5.1.4* Hose connections used for fire purposes only shall be permitted to be connected to wet pipe sprinkler systems only, subject to the following restrictions:

(2) The requirements of 8.17.5.1.4(1) shall not apply to hydraulically designed loops and grids, where the minimum size pipe between the hose connection’s supply pipe and the source shall be permitted to be 2 in. (50 mm).

(3) For piping serving a single hose connection, pipe shall be a minimum of 1 in. (25 mm) for horizontal runs up to 20 ft (6.1 m), a minimum of 11⁄4 in. (32 mm) for the entire run for runs between 20 ft and 80 ft (6.1 m and 24 m), and a minimum of 11⁄2 in. (40 mm) for the entire run for runs greater than 80 ft (24 m). For piping serving multiple hose connections, runs shall be a minimum of 11⁄2 in. (40 mm) throughout.

(5) Where the residual pressure at a 11⁄2 in. (40 mm) outlet on a hose connection exceeds 100 psi (7 bar), an approved pressure-regulating device shall be provided to limit the residual pressure at the outlet to 100 psi (7 bar).

(6) Where the static pressure at a 11⁄2 in. (40 mm) hose connection exceeds 175 psi (12 bar), an approved pressure regulating device shall be provided to limit static and residual pressures at the outlet to 100 psi (7 bar).

I have designed many speculative shell warehouses where class I hose connections were required due to the width of the building, but small hose connections were not required by the AHJ until a tenant leased the building (or portion of) and maintained areas intended for storage.
