Gas cabinets must be constructed of steel that is not less than how thick?

Gas cabinets used for the storage of non-flammable compressed gases need to be constructed with materials that provide adequate protection and strength. The requirement for the thickness of steel in gas cabinets is stipulated to ensure structural integrity and safeguard against potential hazards, such as leaks or accidental ruptures.

The correct answer specifies a minimum thickness of 0.097 inch, which aligns with industry standards for gas cabinet construction. This thickness is necessary to withstand pressure and potential impacts, thereby enhancing the safety of the storage environment for the gases contained within.

In this context, the other thickness options are either insufficient to meet safety standards or do not provide the required level of protection. Options that specify smaller thicknesses would not offer adequate strength, potentially compromising the safety of the cabinet and leading to risks associated with gas storage.
