Occupational safety training for operating air compressors

1. Overview of Air Compressors

a. What is an air compressor?

An air compressor is a device used to compress air from the surrounding environment to a higher pressure. This compression process helps create a stable supply of compressed air with consistent pressure and flow, which is used in a variety of industrial and commercial applications. Air compressors can operate in various ways, including using pistons, screws, gears, or other technologies to compress air.

Air compressors come in various types and sizes, ranging from compact units for household use to large industrial compressors capable of powerful and continuous air compression. These types of compressors have different designs and features to suit specific application needs.

b. How an air compressor works

The working principle of an air compressor is based on increasing the pressure of air by compressing it. This process is carried out through the following basic steps:

• Air Intake: The compressor draws air from the surrounding environment through an intake valve. The air is usually drawn into a chamber or cylinder.
• Air Compression: After intake, the compressor begins compressing the air. This process is typically performed using one or more pistons or rotating screws. As the piston moves up and down or the screw rotates, the pressure in the chamber rises, compressing the air.
• Oil and Water Separation (if needed): In some cases, compressors may also need to separate oil and water from the compressed air. This is usually done with specialized filters and separators.
• Compressed Air Storage: Once compressed to the desired pressure, the air is stored in a pressure tank. This tank helps balance the pressure and provides a stable supply of compressed air.
• Using Compressed Air: Compressed air can be used in various applications, including powering tools and equipment, cooling, drying, and many industrial processes.
• Pressure Reduction (if needed): Before use, the pressure of compressed air is often reduced to ensure it meets the specific requirements of the equipment or application.

c. Industries that use air compressors

Air compressors are used in many different industries. Some key industries where compressors play an important role include:

• Automotive Industry: Compressors provide compressed air for tools and equipment used in car manufacturing, including painting, tire inflation, and other processes.
• Food & Beverage Industry: In this industry, compressors are used to transport food products, package food with gas, and cool production processes.
• Chemical Industry: Compressors are essential in chemical production, including chemical processes and packaging.
• Oil & Gas Industry: Compressors are used in oil and gas production, including drilling and product testing.
• Electronics Industry: In manufacturing electronic components and circuit boards, compressors are used for cleaning and blowing air onto components.
• Metal Industry: Compressors supply air for metal cutting, welding, and other processes in metal production.
• Wood & Furniture Industry: In woodworking and furniture production, compressors power tools and machinery such as sanders, chisels, and cutting machines.
• Paper Industry: Compressors help control and maintain paper production processes, including cleaning and aerating materials.
• Textile Industry: Compressors supply air for sewing machines and other equipment during fabric and garment production.
• Aquaculture & Seafood Processing: In seafood production, compressors are often used to supply air to water treatment systems and provide oxygen for fish ponds.

d. Occupational safety card

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

The Group 3 card shows personal details such as name, date of birth, job, and working environment, along with training duration, official stamp, and signature confirming course completion.

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

• If the employer and employee have a labor contract, the employer must sign and stamp the card for the Group 3 worker after training and passing the test.
• If the worker is freelance or seasonal, without a labor contract, the training unit must sign and stamp the card after the worker completes training and passes the test.

3. Hazards When Operating Air Compressors

Operating air compressors requires careful attention and strict adherence to safety rules to prevent hazards. Below are some common hazards when operating air compressors:

• Explosion and Safety Incidents: If the air compressor operates incorrectly or there is a system failure, there is a risk of explosion due to high compressed air pressure. This can cause serious injuries or even death. Ensure the compressor and compressed air system are properly maintained and meet safety standards.
• High Pressure: Air compressors generate high pressure. Working near pipes or equipment can be life-threatening if a malfunction occurs.
• Noise and Vibration: Air compressors often produce noise and vibrations, which can harm workers’ health if ear and eye protection is not used. Noise and vibration control measures should be applied.
• Oil and Compressed Air Lubricants: Compressors often use oil for lubrication and cooling. Oil leaks or contact with compressed air oil can cause environmental contamination or fire hazards.
• Temperature: Excessive temperature in the compressor system can cause oil overheating or fire. Ensure proper cooling and temperature management.
• Electrical System: Air compressors use high-voltage electricity. Risks of electric shock and fire must be managed.
• Maintenance and Periodic Checks: Neglecting maintenance can lead to malfunctions or fire hazards. Regular inspection and maintenance ensure safe and effective operation.
