Who must generally supervise the storage of compressed gases?

The supervision of the storage of compressed gases is typically the responsibility of individuals holding a G-46 Certificate of Fitness. This specific certification indicates that the holder has the necessary knowledge and training related to the safe handling and storage of compressed gases, which includes understanding the hazards associated with these materials and the proper procedures for storage, use, and emergency response.

Individuals with a G-46 certification are trained in relevant New York City Fire Department regulations and guidelines pertaining to compressed gases, ensuring compliance with safety standards and minimizing risks associated with gas storage. This level of expertise is critical in preventing accidents, such as leaks or explosions, which can have severe implications for safety in various settings, including industrial, commercial, and residential environments.

The other options represent different certificates of fitness that pertain to various aspects of fire and safety regulation but do not specifically address the supervision of compressed gases, making them unsuitable for this particular responsibility.
