Yes, the 2017 National Electrical Code (NEC) addresses the location of the disconnect for MRI equipment. Specifically, look at Article 517, Health Care Facilities, Part VI, Essential Electrical Systems, and Article 517.63, Wiring and Protection. While the specific wording may vary, the intent is to provide a readily accessible and clearly labeled disconnect located outside the MRI room but readily accessible in case of emergency.Here's why it's important and some considerations: Emergency Shutdown

The main purpose of the disconnect is to allow for immediate shutdown of the MRI system in an emergency (e.g., fire, patient entrapment, system malfunction).

Accessibility

The disconnect must be readily accessible to authorized personnel (usually, but not always, outside the MRI room door). Accessibility is key, as seconds can matter in an emergency.

Clear Labeling

The disconnect must be clearly labeled as the MRI power disconnect.

Lockout/Tagout

Provisions for lockout/tagout are crucial for maintenance and repair.

Qualified Personnel

Only qualified individuals are permitted to operate or work on this equipment.

Important Considerations When Installing an MRI Disconnect



Specific Requirements

Consult with the MRI equipment manufacturer for their specific disconnect requirements. They may have stipulations beyond the NEC minimums.

Local Amendments

Always check with your local Authority Having Jurisdiction (AHJ). They may have local amendments to the NEC that further define the requirements.

Collaboration

Collaborate closely with the facility's engineering and safety departments, the MRI vendor, and the electrical contractor to ensure proper placement and functionality of the disconnect.*

Magnetic Field: Be aware of the strong magnetic field around the MRI system. Use non-ferrous materials for enclosures and mounting hardware as appropriate.In summary, while the NEC 2017 provides guidance on the location of the MRI disconnect, it's crucial to consult the manufacturer's specifications, local codes, and collaborate with the relevant parties to ensure a safe and compliant installation. The location, accessibility, and labeling are all key aspects of the disconnect's effectiveness. Flag for review
