1. Overview of the Oil Filter Complex Machine
a. What is the Oil Filter Complex Machine?
The Oil Filter Complex Machine is an integrated system of equipment and technology designed to remove impurities and contaminants from oil, improving its quality. Key components typically include filters, cleaning units, and control devices. This process helps protect machinery and extends the oil’s lifespan, allowing long-term use without damaging the system.
b. Operating Principle of the Oil Filter Complex Machine
The operating principle of the Oil Filter Complex Machine typically includes the following steps:
- Mechanical filtration principle: Uses filters to trap dirt, impurities, and other unwanted compounds. Filters may consist of membrane layers, filter fibers, or materials capable of capturing fine particles.
- Chemical filtration principle: Uses chemicals to interact with harmful substances or those that may affect the oil. These chemicals usually absorb or react with impurities, making them easier to remove.
- Electrical filtration principle: Uses electric fields to attract oppositely charged particles, allowing them to adhere to electrodes and be removed from the oil.
- Liquid separation principle: Uses physical principles, such as gravity, to separate unwanted liquid phases from the oil.
c. Industries that use the Oil Filter Complex Machine
The Oil Filter Complex Machine is widely used across various industries, including:
- Oil & Gas Industry: Used to filter oil from wells and crude oil, removing impurities and contaminants to protect equipment during production.
- Automotive Industry: Used in car engine systems to filter engine oil, keeping it clean and protecting the engine from damage.
- Aerospace Industry: Used in aircraft oil systems to ensure engine safety and performance.
- Shipbuilding Industry: Integrated into ship and fishing vessel oil systems to maintain engine and machinery performance and reliability.
- Manufacturing & Processing Industry: Used in factories to filter oil during production and processing.
- Power Generation Industry: Used in power plants to filter oil in generator systems.

b. Training Duration
Initial safety training duration:
- Total training time is at least 24 hours, including assessment time.
- 8 hours of theory on occupational safety policies and 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 theoretical assessment at the end of the course
The training center may divide the course into multiple sessions depending on employee scheduling. Typically, there are 6 sessions over 3 days, provided the company arranges continuous learning time.
Periodic safety training duration:
- Before the occupational safety card expires, employees seeking renewal must undergo periodic safety training, with the periodic training duration being at least 50% of the initial training duration.
Explanation: The total duration of periodic safety training is at least 12 hours, including assessment time. Upon successful completion and passing the exam, the employee is reissued or extended their occupational safety card.

d. Occupational Safety Card
Upon completion of the occupational safety training and passing the exam, employees are issued an occupational safety card (commonly called a Group 3 safety certificate).
The Group 3 safety card shows details such as full name, date of birth, job position, and work environment. It also includes training duration, official stamp, and signature confirming completion.
According to Clause 2 of Article 24 of Decree 44/2016/ND-CP, there are two cases:
- If there is a labor contract between the employer and employee, the employer must sign and stamp the safety card for the Group 3 employee after completing training and passing the exam from an authorized training unit.
- If the employee is freelance or temporary without a labor contract, the training unit must sign and stamp the safety card after the employee completes the training and passes the exam.

3. Hazards When Operating the Oil Filtration Machine System
Operating the Oil Filtration Machine System can sometimes involve certain hazards, including:
- If regular maintenance is not performed or filters are not replaced when needed, the performance of the oil filtration system may decrease significantly. This can lead to damage to other equipment and machinery in the system.
- Technical issues such as leaks, pressure drops, or control system errors can occur, compromising safety and performance.
- Uncontrolled oil loss during the filtration process can reduce oil quality and decrease system efficiency.
- In hazardous environments, some oils may contain flammable materials. Improper filtration can increase the risk of fire or explosion.
- Operators must be fully trained on how to use and maintain the oil filtration system. Lack of knowledge can lead to accidents and safety risks.
To minimize hazards, regular maintenance, employee training, and adherence to safety procedures are crucial when operating the Oil Filtration Machine System.
4. Measures to Control Occupational Accidents When Operating the Oil Filtration Machine System
To control occupational accidents when operating the Oil Filtration Machine System, several important safety measures should be implemented:
- Employee training: Train staff on operation, maintenance, and safety procedures for the Oil Filtration Machine System. They must understand potential risks and preventive measures.
- Follow safety procedures: Develop and implement safe working procedures, including proper filter replacement, regular inspections, and system maintenance. Adhering to these procedures reduces the risk of incidents.
- Use protective equipment: Ensure employees wear full personal protective equipment (PPE) such as helmets, safety goggles, gloves, and protective clothing to guard against potential hazards.
- Regular inspections: Conduct routine checks on the Oil Filtration System to detect technical issues or maintenance needs early.
- Restrict unsafe access: Limit access to the machine area, placing warning signs and safety instructions.
