I think the standard makes a distinction between large equipment with internal access and mechanical/equipment rooms. Being a mechanical/equipment room, your answer will boil down to the ease of access and the likelihood the owner (or their maintenance personnel) will use the open space for storage.
I'm working on a small hospital that has a hydro-therapy room - very similar to what you describe. In this case, maintenance access is via a trap door in the pool deck and steep ladder leading down to the pit. I wouldn't expect large quantities of storage, but the less-than-impossible access combined with the open space - we're sprinklering it.

Sprinklers shall not be required to be installed within electrical equipment, mechanical equipment, or air handling units not intended for occupancy. It is not the intent of 9.2.10 to require sprinklers to be installed in air handling units (AHUs) or in similar mechanical or electrical equipment. AHUs for large buildings and building complexes can be so large that it brings into question whether sprinklers should be installed inside them. Providing sprinkler protection in such units is not practical and would not be overly effective based on the limited hazard present. A.9.2.10 Equipment having access for routine maintenance should not be considered as intended for occupancy. AHUs that have access panels or “man doors" are not necessarily intended for occupancy and should not be treated as such when applying 9.2.10. Often the presence of an access hatch or other means to allow for equipment maintenance is misconstrued as allowing occupancy of such a space.
