Is there a code (NEC, NFPA, BICSI, TIA or EIA) that dictates that a Telecom room in a commercial building can not be used to store supplies (paper, paper towels, computer monitors, etc)?
Try posting this question in the "IEEE (electrical) Code Issues" and "NFPA (fire) Code Issues" forums in the Engineering Codes, Standards & Certifications section.
They may have a better idea of any codes concerning this issue.
