Where is the refilling of compressed flammable gas containers strictly prohibited?

Refilling compressed flammable gas containers is strictly prohibited in New York City due to strict safety regulations aimed at preventing accidents and ensuring public safety. The density of population, the presence of numerous commercial establishments, and the potential hazards associated with the storage and use of flammable gases contribute to the city's stringent rules. By prohibiting the refilling of these containers within city limits, authorities aim to minimize the risk of explosions and fires that could result from improper handling.

In contrast, other cities may have different regulations regarding this practice, which could allow for refilling under specific circumstances or with proper licensing and safety measures. The regulations in New York City are designed to address the unique challenges posed by its urban environment and high-rise buildings, where the consequences of a gas-related incident can be catastrophic.
