Natural gas, butane, and hydrogen containers adhere to different regulatory standards due to their unique properties and applications. Natural gas is typically governed by separate codes focusing on utility service lines and appliances in residential and commercial settings, while butane is often regulated under different standards primarily relating to its use and storage. Hydrogen, being a lighter-than-air gas and used in specific applications like fuel cells, also falls under distinct guidelines. Each of these gases has different handling, storage, and installation standards tailored to their specific characteristics and safety requirements.
