Final answer:
The clearance required for the installation of surface-mounted fluorescent fixtures above a storage space depends on local building codes, but the question does not provide enough detail to give a definitive answer. Consultation of local codes or the NEC is recommended.
Step-by-step explanation:
The question appears to be related to building codes or standards regarding the installation of fluorescent lighting fixtures in relation to storage spaces. While specific building codes can vary by location, a general guideline is that there should be adequate clearance between the lighting fixture and storage areas to prevent fire hazards and ensure proper illumination.
However, to provide an accurate answer, one would need to refer to the specific building codes applicable in the area where the installation is to take place. Since this information is not provided in the question, it is not possible to provide a definitive answer. Therefore, a general recommendation would be to consult the local building codes or the National Electrical Code (NEC) for the exact clearance requirements for the installation of surface-mounted fluorescent fixtures.
