Is there a required clearance between mobile pedestals and HVAC floor registers?

Yes. Mobile pedestals should not be placed directly over or in front of HVAC floor registers or return-air grilles. Blocking a floor register with a pedestal reduces airflow and can cause HVAC imbalance, overheating of the pedestal contents, and potential fire code violations (NFPA 90A requires that air distribution equipment remain accessible and unobstructed). Maintain at least 12"–18" of clearance between a pedestal and any floor HVAC register. When planning a workstation layout, map floor registers first and position pedestals around them.
