Non-Magnetic Tools

Non-Magnetic Tools are the hand tools your biomed department, facilities crew, and scanner service engineers reach for when work has to happen inside the magnet room. A standard steel screwdriver or wrench carried into Zone IV can be pulled toward the bore with enough force to injure a person or damage the scanner, and the static magnetic field is always on, whether or not a scan is running. Non-ferrous hand tools remove that hazard so routine maintenance, coil repairs, and construction work can proceed without waiting for the magnet to be ramped down.

MRI Med carries a full range of non-magnetic tools for MRI environments, from complete MRI tool kits to individual screwdrivers, wrenches, pliers, hex keys, sockets, and scissors. The category also includes construction tools for contractors working near magnets and titanium surgical instruments for clinical procedures in the MRI suite. Every item is selected for use in Zone III and Zone IV, where conventional steel tools do not belong.

The projectile effect, sometimes called the missile effect, is the reason this category exists. Ferromagnetic objects experience a pull that increases sharply as they approach the magnet, and a tool that feels inert in the hallway can become a projectile a few feet from the bore. Hand tools figure in many reported incidents because they are small, easy to pocket, and easy to forget.

Under ASTM F2503, equipment is classified as MR Safe, MR Conditional, or MR Unsafe. MR Safe items pose no known hazards in any MR environment because they are non-conducting, non-metallic, and non-magnetic. MR Conditional items are safe within specified conditions such as field strength and spatial gradient. Almost no metal hand tools, even non-ferrous ones, are labeled MR Conditional or sold with a formal classification, so check the ferrous properties of each product and confirm the conditions match your scanner rather than assuming a tool is safe for use.

Keeping a dedicated set of MR Conditional tools in the suite, clearly labeled and stored in Zone III, is a simple control that supports the ACR Guidance Document on MR Safety Practices and the screening expectations accreditation surveyors look for.

Start with the work you actually do in the magnet room. A biomed technician servicing coils needs a different mix than a contractor cutting drywall, and an imaging center manager may simply want one standardized kit at each scanner.

Consider materials. Non-magnetic tools are commonly made from aluminum bronze, titanium, and certain austenitic stainless steels. Each material trades off differently between hardness, weight, and cost, and some austenitic stainless alloys can become mildly magnetic after cold working. Read the product description for each item rather than assuming all non-ferrous tools behave the same way.

Verify before entry. Even tools purchased as non-magnetic should be checked with a test magnet before they go into Zone IV, and rechecked periodically as items are replaced, as they can easily be mistaken for a traditional, magnetic tool and swapped on accident. MRI Med's MRI Safety Category includes Test Magnets and Ferromagnetic Detection products that make this a quick step.

Plan for storage and labeling. Non-ferrous tools should live in a dedicated, labeled case that stays in Zone III, not in the general facilities shop where they will be mixed with steel. Finally, think about who else enters the suite. Outside contractors and electricians rarely arrive with non-ferrous tools of their own, so a loaner kit and clear signage at the Zone IV entry close a gap many facilities overlook.

MRI Med designs, manufactures, and distributes products for the MRI market and is owned and operated by a group with more than 80 years of combined MRI experience. The tools offered here are selected for real MRI room maintenance work, not repurposed from a general industrial supply list.

Because MRI Med serves the whole suite, Non-Magnetic Tools can be ordered alongside MRI Safety products, MRI Suite Furniture, and MRI Carts in one purchase order, which simplifies procurement for radiology managers and purchasing agents. Orders ship from California, and support is available Monday through Friday during Pacific business hours. If you need help building a set for a new suite, call or email MRI Med and a knowledgeable representative will assist.
