Health and Safety Guidelines for Micro CT Scanning with the Nikon XTH 225 ST

At the Natural Sciences Museum, safety is our top priority. Our state-of-the-art Nikon XTH 225 ST micro CT scanner provides researchers with exceptional imaging capabilities, but its advanced technology requires strict adherence to health and safety protocols. This page outlines the essential safety procedures for using the Nikon XTH 225 ST to ensure a safe and efficient scanning experience.

Operator Training
Only trained personnel are authorized to operate the Nikon XTH 225 ST micro CT scanner. Users must undergo appropriate training and familiarization with the equipment to ensure safe operation. Training includes understanding the scanner’s function, identifying hazards, and knowing emergency procedures.

Personal Protective Equipment (PPE)
All users must wear appropriate PPE when operating the micro CT scanner, including:

• Lab Coats.
• Gloves: For handling specimens safely.

Scanner Area Access
Only authorized personnel should be allowed in the vicinity of the Nikon XTH 225 ST during scanning. The scanning area should be clearly marked and restricted to prevent unauthorized access. Signage should indicate when the system is active, and access is prohibited.

X-ray Exposure Control
The Nikon XTH 225 ST operates using X-ray technology, which can potentially expose users to harmful radiation. Therefore, users should:

• Always ensure that the scanner is properly shielded during operation.
• Maintain a safe distance from the scanner when it is in use.
• Never attempt to modify or bypass safety controls.

Radiation Shielding
The micro CT scanner is equipped with built-in shielding to protect operators from radiation exposure. Always check that these shields are in place and functioning properly before use. Any damage or malfunction must be reported immediately, and the scanner should not be used until repaired.

Scanner Calibration and Maintenance
The Nikon XTH 225 ST should undergo regular calibration and maintenance as part of our safety protocols. This ensures that the scanner operates within safe parameters. Only qualified maintenance personnel should perform any repairs or adjustments to the scanner.

In the Event of a Radiation Incident
In the event of accidental exposure to X-rays, immediate action should be taken:

• Alert a supervisor: Notify your supervisor immediately.
• Exit the radiation area: Evacuate the area calmly and promptly.
• Medical attention: Seek medical attention if exposure is suspected or if any symptoms arise.

Equipment Malfunction
If the Nikon XTH 225 ST malfunctions or is suspected to be malfunctioning, stop using the machine immediately. Do not attempt to troubleshoot or repair the machine yourself. Inform the health and safety officer and technical staff to assess the issue. Always follow the manufacturer’s instructions for safe operation.

Fire Safety
In the event of a fire, follow the emergency evacuation procedures posted in the facility. Use fire extinguishers only if trained to do so. The scanner area should always have access to fire exits, and the emergency alarms should be clearly audible.

Specimen Preparation
Proper preparation of specimens is critical for both safety and quality of results:

• Ensure that specimens are free of hazardous materials.
• Always handle specimens using the appropriate equipment to avoid injury or contamination.
• If the specimen is fragile or toxic, take extra precautions to minimize exposure and damage.

Safe Placement of Specimens
Always place specimens on the scanner bed carefully, ensuring that they are secured properly before beginning the scan. Avoid placing any materials on or near the scanner’s X-ray source that are not intended for imaging, as this could cause damage to both the specimen and the scanner.

Pre-Scan Checks
Before starting a scan, confirm that all safety procedures have been followed, including the proper setup of the specimen, appropriate shielding, and the absence of any unauthorized personnel in the scanner area.

Monitoring During Scans
While the scanner is operating, the area should be monitored continuously. The system should never be left unattended during scanning unless proper shielding and protocols are in place. Make sure emergency stops and safety mechanisms are easily accessible in case of malfunction.

Post-Scan Procedures
Once the scan is complete, ensure that the X-ray source is powered off, and the scanner is secure before handling the specimen or leaving the area. Clean and disinfect any surfaces that may have come into contact with hazardous materials or biological samples.

By adhering to these safety guidelines, users can ensure that they are operating the Nikon XTH 225 ST micro CT scanner safely and effectively. The equipment is a powerful tool that aids in significant scientific research, and its safe use is essential for achieving accurate results while safeguarding the health of operators and the integrity of the specimens.
