Cato Introduces an MR-Safe Fire Protection Cabinet

May 23, 2025

Cato’s Island Chief cabinet is now labeled MR-Safe in accordance with ASTM F2503. The cabinet is constructed of all non-magnetic materials and is safe to use in a magnetic resonance imaging environment.

The Island Chief is a surface-mounted cabinet that now comes in a larger size to accommodate non-magnetic fire extinguishers and up to 20lb ABC fire extinguishers offered through JL Industries. Please see our submittal for a list of specific extinguisher models that will now be accommodated by this cabinet.

Cato’s cost-effective plastic Island Chief fire extinguisher cabinets are manufactured in the US, are available in red or white and each cabinet is labeled with the green MR Safe label.
