Occupational Safety Training for Plasma Cutting Machine Operation

1. Overview of Plasma Cutting Machines

a. What is a Plasma Cutting Machine?

A Plasma Cutting Machine is an industrial device used to cut ductile materials such as steel, stainless steel, aluminum, and other metals using the high thermal intensity of plasma. Plasma is a state of matter, usually in the gaseous state, created by heating compressed or supplied gas in an electrically insulated tube.

The plasma cutting process occurs when a high-frequency electric current is used to ionize and heat the plasma, generating a powerful form of thermal energy. When the plasma is hot enough, it can cut through ductile materials by melting them and blowing them away from the cutting area. This process allows for high-precision cuts and sharp cutting edges.

Plasma cutting machines are commonly used in industrial applications such as metal fabrication, construction, mechanical engineering, and metal manufacturing. They are also used to create custom patterns and designs. Plasma cutting machines can be computer-controlled to ensure high accuracy and easily produce complex cut products.

b. Applications of Plasma Cutting Machines in Manufacturing

Plasma cutting machines have many important applications in the manufacturing industry due to their cutting precision and efficiency. Below are some common applications of plasma cutting machines in production:

• Metal Fabrication: Plasma cutting machines are widely used in the metal fabrication industry to cut and process metal sheets such as carbon steel, stainless steel, aluminum, copper, and titanium. They help produce high-precision metal components for applications such as frames, assembly surfaces, and machinery parts.
• Construction: In construction, plasma cutting machines are used to cut metal sheets and other metal components to create steel structures, columns, and other parts for projects like bridges, high-rise buildings, and factories.

2. Overview of Occupational Safety Training for Operating Plasma Cutting Machines

a. What is Occupational Safety Training?

• Occupational safety training for operating plasma cutting machines consists of sessions that equip workers with awareness of how to prevent workplace accidents. Workers directly operating plasma cutting machines belong to Group 3.
• The occupational safety training course helps workers recognize and avoid hazards, reducing the risk of workplace accidents during work.

b. Training Duration

Initial Occupational Safety Training Duration

• Total training duration is at least 24 hours, including assessment time.
• 8 hours of theory on the system of policies and laws on occupational safety and hygiene
• 8 hours of theory on basic knowledge of occupational safety and hygiene
• 4 hours of theory on specialized training content
• 2 hours of practice on specialized training content
• 2 hours of theory assessment at the end of the course

The safety training center will distribute the course into multiple sessions depending on the worker schedule. Typically, there are 6 training sessions over 3 days, provided the company arranges continuous learning time.

Periodic Occupational Safety Training Duration

• Before the occupational safety card expires, employees seeking renewal must complete a periodic occupational safety training course with a duration of at least 50% of the initial training duration.

Explanation: The total duration of periodic occupational safety training is at least 12 hours, including assessment time. Upon completion and passing the assessment, employees will have their occupational safety card renewed.

c. Training Course Content

d. Occupational Safety Card

After completing the occupational safety training course and passing the assessment, employees will be issued a safety card (commonly called a Group 3 safety certificate).

The Group 3 card shows full name, date of birth, specific job and working environment. It also contains training duration, red stamp, and signature confirming course completion.

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

• If the employer and employee have a labor contract, the employer must sign, stamp, and endorse the safety card for Group 3 employees after they complete the training and pass the assessment.
• If the employee is freelance or temporary without a labor contract, the training unit must sign, stamp, and endorse the safety card after the employee completes the training and passes the assessment.

3. Hazards When Operating a Plasma Cutting Machine

Operating a plasma cutting machine can pose several hazards to both users and the work environment. Below are the main hazards that should be considered when working with a plasma cutter:

• Risk of fire and explosion: Plasma can reach extremely high temperatures, and working near it may cause a fire or explosion, especially with flammable materials. Safety rules for fire prevention should be followed, and personal protective equipment such as protective clothing, safety goggles, and heat-resistant gloves should be used.
• Emission of toxic gases: Plasma cutting may produce harmful gases such as metal fumes and flux fumes. These can be hazardous to health if proper ventilation systems are not used and safety regulations for toxic gases are ignored.
• UV and X-ray radiation: Plasma cutting can emit UV and X-ray radiation, which can harm the eyes and skin. Operators should wear UV-protective goggles and protective clothing when exposed to plasma.
• High voltage: Plasma cutting machines usually operate at high voltage to generate plasma. Users must follow electrical safety rules and avoid contact with high-voltage parts of the machine.
• Heavy metal contamination: Fumes and dust generated during plasma cutting may contain toxic heavy metals such as lead and cadmium. Protective equipment and appropriate air filtration systems are essential to prevent poisoning.
• Bodily injury from cutting: Due to the sharp nature of plasma, failing to follow safety rules can result in severe injuries. Users must be trained in safe plasma cutter operation and comply with safety procedures.

To ensure safety when operating a plasma cutting machine, users must adhere to safety regulations, particularly regarding personal protective equipment and safe handling of materials and toxic gases. This helps minimize potential hazards and ensures a safe working environment for all employees.

4. Accident Prevention Measures When Operating a Plasma Cutting Machine

To control occupational accidents when operating a plasma cutting machine and ensure employee safety, the following measures should be implemented:

• Employee training: Provide safety training to all employees working with plasma cutters. Ensure they fully understand the hazards and safety measures required, as well as machine operation rules.
• Use of personal protective equipment: Require employees to wear complete personal protective equipment, including safety goggles, protective clothing, heat-resistant gloves, and safety shoes. Ensure protective equipment is inspected and maintained regularly.
• Machine inspection and maintenance: Conduct regular inspections and maintenance to ensure the plasma cutting machine operates safely and correctly. Repair or replace any defective parts immediately.
• Smoke extraction system: Install a smoke and air filtration system to remove toxic gases and harmful dust from the workplace.
• Electrical safety: Ensure the plasma cutter is connected properly and electrical safety regulations are followed. Minimize contact with high-voltage parts of the machine.
• Workplace management: Keep the workspace clean and well-ventilated to prevent fire risks and enhance toxic gas management.
• Work environment inspection: Regularly inspect the workplace to ensure there is no flooding, subsidence, or other hazards that may cause accidents.
• Machine usage regulations: Ensure employees use the plasma cutter only if trained and experienced. Strictly enforce machine usage rules and limit access to untrained personnel.
• Risk management: Conduct risk assessments to identify potential hazards and develop control plans, including identifying dangerous areas and implementing preventive measures.
• Warning and alarm systems: Install alert and alarm systems to warn employees in case of risk or incidents.
• Periodic inspection of plasma cutting machines to detect early safety issues such as mechanical wear or damage, thereby reducing occupational accident risks.
