Steel cylinders contain a substantial quantity of ferromagnetic material and MUST NOT be used in proximity to MRIs under any circumstances.

When medical gas cylinders are intended for use in a room in which magnetic resonance imaging (MRI) is being performed, the cylinders and associated equipment must be considered to potentially contain ferromagnetic materials.

Coregas recommends that the standard safety protocols for determining what materials may be brought into proximity with an MRI are applied to all gas cylinders and equipment.
