Occupational Safety Training for Operating MRI Machines

1. Overview of MRI Machines (Magnetic Resonance Imaging)

a. What is an MRI Machine (Magnetic Resonance Imaging)?

MRI (Magnetic Resonance Imaging) machines are medical devices widely used to create cross-sectional images of the human body and internal structures without using X-rays or any other ionizing radiation. Instead, MRI uses strong magnetic fields combined with radio waves to generate images. Modern MRI machines can often produce high-resolution images, providing detailed information about the structure and function of body parts.

MRI can image many parts of the body, including the brain, spine, joints, muscles, heart, liver, and many other organs. This technology is commonly used in medical diagnostics to help physicians identify health problems, such as diseases, injuries, or normal body variations.

b. How an MRI Machine Works (Magnetic Resonance Imaging)

The operating principle of an MRI machine is based on the interaction between a strong magnetic field and atoms in the body, especially hydrogen atoms (1 proton) in water molecules. Under the influence of the magnetic field and radio waves, these atoms move and emit signals, which are then used to generate images of the body.

Here is a detailed analysis of how an MRI machine works:

• Creating a strong magnetic field (B0): The MRI generates a strong magnetic field, typically ranging from a few to several tens of Tesla (T). This field causes the atomic spins in the body to be displaced from their equilibrium state.
• Excitation by radio waves (RF): A radio wave is applied simultaneously with the strong magnetic field. The radio wave frequency corresponds to the Larmor frequency of atoms in the magnetic field. When excited, the atoms move out of equilibrium.
• Signal emission (MR Signal): When the radio wave is turned off, atoms return to equilibrium and emit signals. These signals are recorded and analyzed.
• Signal processing and image formation: Signals from body atoms are collected by receiver antennas and converted into images using image processing algorithms. These images show how body structures respond to the magnetic field and radio waves, providing information about the structure and properties of tissues and organs.

c. Industries Using MRI Machines (Magnetic Resonance Imaging)

MRI is an important technology in the medical field and is widely used across various specialties:

• Medicine: MRI is used to diagnose and monitor many different conditions. It can generate detailed images of the brain, spine, joints, muscles, heart, liver, kidneys, uterus, prostate, and many other organs and tissues. MRI is also used to track disease progression, assess therapy effects, and guide complex surgeries.
• Medical research: MRI plays a key role in understanding body structure and function and in developing and evaluating new treatments.
• Sports medicine: MRI is used to evaluate injuries and abnormalities in athletes and physically active people, helping to identify muscle, ligament, and joint injuries for treatment and recovery.
• Pharmaceutical research: MRI is used to monitor the effects of new drugs and therapies and to evaluate their impact on the body.
• Veterinary medicine: MRI is also used in animal research and diagnostics, such as studying diseases and animal biology.

2. Overview of Occupational Safety Training for MRI Operation (Magnetic Resonance Imaging)

a. What is Occupational Safety Training?

• Occupational safety training for operating MRI machines provides sessions to equip workers with awareness on preventing workplace accidents. Workers directly handling MRI machines belong to Group 3.

b. Training Duration

Initial safety training:

• Total training time is at least 24 hours, including testing.
• 8 hours of theory on policies and labor safety regulations
• 8 hours of theory on basic occupational safety knowledge
• 4 hours of theory on specialized training content
• 2 hours of practical training on specialized content
• 2 hours of final theoretical test

The training center will arrange multiple sessions depending on workers’ availability. Typically, there are 6 sessions over 3 days if continuous scheduling is feasible.

Periodic safety training:

• Before the occupational safety card expires, workers must take periodic safety training with at least 50% of the initial training duration.

Explanation: Total periodic training time is at least 12 hours, including testing. After completing the training and passing the test, workers will have their safety card reissued and extended.

c. Training Content

d. Occupational Safety Card

After completing the training and passing the test, workers will be issued an occupational safety card (commonly referred to as Group 3 occupational safety certificate).

The Group 3 card shows personal information, date of birth, job, work environment, training duration, red seal, and signature confirming training completion.

According to Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:

• If the employer and employee have an employment contract, the employer must sign and stamp the card after the employee completes training and passes the test.
• If the worker is freelance or seasonal, without an employment contract, the training unit must sign and stamp the card after the worker completes training and passes the test.

3. Hazards for Workers Operating MRI Machines (Magnetic Resonance Imaging)

Operating MRI machines (Magnetic Resonance Imaging) requires strict adherence to safety measures to ensure worker safety. Below are some common hazards that workers may face when operating MRI machines:

• Effects of strong magnetic fields: MRI machines generate strong magnetic fields to create images, and exposure to these fields can affect health. Workers must follow safety instructions regarding strong magnetic fields and avoid direct exposure without proper protective equipment.
• Electrical safety hazards: MRI machines operate at high voltages and can create dangerous situations if not handled properly. Workers need thorough electrical safety training and must follow safety procedures when working near electrical equipment.
• RF (Radiofrequency) hazards: RF waves used during imaging can induce currents in the body, especially if metal or conductive implants are present. This can cause heating or bodily stimulation if safety guidelines are not followed.
• Working in a strong magnetic field environment: Prolonged work in a strong magnetic field can cause dizziness, nausea, headaches, and discomfort. People with medical implants such as pacemakers, defibrillators, or metal implants may be at risk if safety instructions are not followed.
• Chemical and material hazards in the MRI room: Some materials and chemicals in the MRI room may be harmful if not used correctly. Workers must be trained to safely use and handle these materials and chemicals.

To minimize these hazards, medical facilities and organizations must implement safety measures, train workers properly, provide appropriate protective equipment, and comply with safety regulations and guidelines related to MRI operation.

4. Occupational Accident Control Measures for Operating MRI Machines (Magnetic Resonance Imaging)

To control occupational accidents when operating MRI machines, a series of specific safety measures must be implemented. Key measures include:

• Training and education: Provide comprehensive and ongoing training for all staff on MRI safety. Training should cover safety rules, accident prevention measures, use of protective equipment, and emergency response.
• Use of protective equipment: Ensure all MRI operators are provided with and use full protective equipment such as reflective vests, safety goggles, and helmets to protect against strong magnetic fields and other hazards.
• Hazard identification and elimination: Assess and identify potential hazards related to MRI operation, including strong magnetic fields, electrical hazards, and exposure to chemicals and materials in the working area. Implement measures to eliminate or minimize these risks.
