Shop by MRI Safety Sign Type

• 2-Line MRI Room Signage: Mark permanent MRI rooms and control areas with concise identification in raised text and braille.
• 3-Line MRI Room Signs: Provide additional space for longer permanent room names or multi-part identification in raised text and braille.
• Custom Regulatory Signs: Create MRI caution signs with symbol for strong magnetic fields, controlled access, screening, or facility-specific hazards.
• Custom Informational Signs: Communicate screening reminders, metal-removal instructions, equipment notices, and other location-specific messages.
• Authorized Personnel Only Signs: Help limit entry to MRI rooms, control areas, equipment rooms, and other restricted spaces.

MRI Caution Signs & Access Warnings

Use MRI caution signs to warn patients, visitors, and staff about strong magnetic fields, restricted access, and required screening before entry. Custom options allow facilities to select the symbol and message appropriate for each controlled area.

Common messages include:

• DANGER: STRONG MAGNETIC FIELD
• MAGNET IS ALWAYS ON
• RESTRICTED ACCESS
• SCREENED MRI PATIENTS AND STAFF ONLY
• NO METAL OBJECTS
• AUTHORIZED PERSONNEL ONLY

MRI In Use Signs

An MRI in use sign at a closed door alerts patients, visitors, and staff that an examination is underway and entry is restricted. Common messages include MRI IN USE, EXAM IN PROGRESS, DO NOT ENTER, and WAIT FOR STAFF ASSISTANCE.

Because the magnetic field may remain active even when an examination isn’t underway, an MRI in use sign should supplement—not replace—permanent magnetic-field and restricted-access warnings.

MRI Zone Signage Requirements

The American College of Radiology recommends identifying Zone III entrances with signage that denotes the zone and communicates appropriate access restrictions. Zone IV should be clearly marked as potentially hazardous because of the strong magnetic field. For superconducting systems, the Zone IV entrance should also display a prominent illuminated warning stating that the magnet is always on.

Review the ACR Manual on MR Safety, then confirm required wording, symbols, placement, and access controls with the facility’s MR medical director or MR safety officer and the MRI system manufacturer.
