What requirement must be fulfilled when storing compressed non-flammable gases over a certain quantity?

When storing compressed non-flammable gases over a certain quantity, a specific permit is indeed required. This requirement is in place to ensure safety and compliance with regulations, as the storage of large quantities of compressed gases poses risks such as leaks or ruptures that can lead to hazardous situations. The permit process typically involves inspections and adherence to safety standards set by relevant authorities, which helps ensure that facilities are well-prepared to handle the potential dangers associated with such materials. The permitting process may also involve specifying the manner of storage, ensuring that it follows all applicable codes and practices, thus creating a safer environment for personnel and the community.

In contrast, supervision by trained personnel, outdoor storage only, or transportation only on weekends do not typically form part of the core legal requirements governing the storage of compressed gases and may not address the regulatory framework comprehensively.
