Appliances installed in an underground parking garage shall meet which of the following standards?

Appliances installed in an underground parking garage must meet the standards set forth in NFPA 88A. This standard specifically addresses the design, installation, and maintenance of parking structures, including the safety requirements for appliances used in such environments. It emphasizes the need for proper ventilation, fire safety measures, and risk management practices to prevent hazards associated with the accumulation of gases and vapors in enclosed spaces.

NFPA 70 pertains to the National Electrical Code, which focuses on electrical installations but does not specifically address the unique conditions of underground parking garages. NFPA 54 deals with the installation of gas piping and appliances but lacks the comprehensive angle on the structure and ventilation required for parking facilities. NFPA 101 is the Life Safety Code, which focuses on general life safety in buildings rather than specifically addressing the installation standards for appliances in parking garages.

Therefore, choosing NFPA 88A aligns with the specific considerations for safety and compliance needed in underground parking structures, making it the most appropriate standard among the options provided.
