MR Unsafe What does this mean?
MR Safe

MR Safe – an item that poses no known hazards in all MRI environments. Using the terminology, “MR Safe” items are non-conducting, non-metallic, and non-magnetic items such as a plastic Petri dish. An item may be determined to be MR Safe by providing a scientifically based rationale rather than test data.

MR Conditional

MR Conditional – an item that has been demonstrated to pose no known hazards in a specified MR environment with specified conditions of use. “Field” conditions that define the MR environment include static magnetic field strength, spatial gradient magnetic field, dB/dt (time rate of change of the magnetic field), radio frequency (RF) fields, and specific absorption rate (SAR). Additional conditions, including specific configurations of the item (e.g., the routing of leads used for a neurostimulation system), may be required.

MR Unsafe

MR Unsafe – An item that is known to pose hazards in all MRI environments. MR Unsafe items include magnetic items such as a pair of ferromagnetic scissors.

Improve safety in your MRI suite with the MAGNET ALWAYS ON LED Warning Sign from MRImed. This single-sided LED warning sign clearly displays "Magnet Always On" in bold red lettering against a white background, ensuring crucial safety information is visible to both patients and staff. The high-visibility LED lights provide an effective, continuous reminder of magnetic hazards, helping to prevent accidental entry into restricted MRI areas. Designed for wall mounting, this energy-efficient and economical warning sign connects via a 120 VAC hardwired setup for consistent, reliable operation. Note: This product is not MRI safe and does not include a battery backup.

Key Features

  • Optimized for MRI Equipment Safety: Clearly marks magnet-on status near MRI rooms, improving patient and staff safety.
  • Bright LED Illumination: Energy-efficient LEDs ensure the message is visible from a distance, day or night.
  • Durable Single-Sided Design: Displays a prominent safety warning with red text on a white background.
  • Hardwired Installation (120 VAC): Ensures consistent power; does not rely on plug-in or battery backup.
  • Wall-Mountable & Economical: Easy to install and cost-effective for all types of MRI facilities.
  • MR Unsafe: For installation outside of MRI-protected zones.

Frequently Asked Questions

1. Where should an LED “Magnet Always On” warning sign be installed in an MRI suite?

This LED sign is designed for placement outside MRI-protected zones, typically at the final checkpoint before staff or visitors enter Zones III or IV. Facilities mount it near magnet-room doors, control-room exits, or screening areas so everyone approaching the field can clearly see that the magnet is energized at all times. Because it’s not intended for use inside magnet-exposed areas, it’s hardwired in a safe location where it can deliver a bright, constant warning without interfering with MRI operation.

2. How visible is the LED sign in busy MRI hallways or low-light areas?

The red LED display is easy to read from a distance, whether the hallway is brightly lit or dim. The illuminated lettering cuts through shadows, glare, and typical MRI-suite lighting conditions, which makes it far more noticeable than a standard printed sign. Many MRI teams prefer LED warnings for high-traffic corridors because the constant glow reduces the chance of someone overlooking the magnet hazard.

3. What power setup does the sign require, and does it need any ongoing maintenance?

The sign uses a hardwired 120 VAC connection, which gives you consistent, always-on illumination without relying on plug-in power or batteries. Beyond basic electrical installation, it requires very little upkeep—just occasional surface cleaning to keep the faceplate clear. Since it doesn’t include a battery backup, most sites connect it to a reliable circuit in an area with stable power, ensuring uninterrupted visibility.
