Which standard specifies how to handle flammable liquids in storage?

NFPA 30, also known as the Flammable and Combustible Liquids Code, specifically outlines the safe handling and storage of flammable and combustible liquids. This standard provides comprehensive guidelines to minimize risks associated with the fire and explosion hazards of these substances. It addresses aspects such as the classification of liquids, storage techniques, compatible storage requirements, and necessary precautions to be taken when handling these materials.

In contrast, other standards mentioned serve different functions. NFPA 70 pertains to the National Electrical Code, which regulates electrical installations. NFPA 101 is the Life Safety Code, focusing on building occupancy and egress to ensure safety in emergencies. NFPA 415 deals with the standard for the construction and protection of airplane hangars. Thus, NFPA 30 is the most relevant and authoritative standard concerning the storage and handling of flammable liquids, making it the correct choice.
