Frequently Asked Questions


Why are MR Safe cabinets paired with MR Conditional extinguishers?
MR Safe cabinets contain no metal and can be installed inside the MRI room. Fire extinguishers contain required metal components, so they are classified as MR Conditional with a specific Tesla rating.

Can any non-magnetic extinguisher be mounted inside an MRI room?
No. Even if an extinguisher is non-magnetic, it must be third-party tested and labeled MR Conditional with a specific Tesla rating—such as 3T, 7T, or 11.7T. And that rating must meet or exceed the magnetic field strength specified by the MRI manufacturer or the facility’s safety requirements.

Why can't fire extinguishers be MR Safe?
All extinguishers contain a pressure vessel, valve components, and internal parts made of metal. MR Safe requires no metal whatsoever.
