Risks and Preventive Measures for Use of Air Compressors

The air compressors have various risks during use, which may involve the equipment itself, the operator, and the surrounding environment. In order to ensure safety, effective preventive measures must be taken. The following is a detailed analysis and preventive measures for the use of air compressors: 1. Risks of use of air compressors

1. Fire and explosion risks
   • Risk reasons:
     • Diesel used in diesel-powered air compressors is a Class B hazardous chemical, and improper storage and transportation can easily cause fires and explosion accidents.
     • The high-pressure gas and possible oil and gas mixtures inside the compressor may cause an explosion under certain conditions. For example, cylinders, gas reservoirs, and air delivery pipelines can explode due to overtemperature and overpressure; atomized lubricating oil or its decompositions can also cause explosions.
     • When repairing and installation work, flammable liquid falls into the cylinder, air reservoir and air conduit, which may cause an explosion when the air compressor is started.
     • Electrical failures, such as line aging, short circuit, insulation damage, etc., may also cause fires.
   • Risk Consequences: Equipment damage, casualties, production interruptions, etc.
2. Risk Risk
   • Risk Causes: The air compressor driven by the motor has electrical problems such as broken equipment power cord, ungrounded equipment, and damaged junction box.
   • Risk Consequences: Operators are injured or killed by electric shock.
3. Mechanical injury risk
   • Risk reasons:
     • Rounding components such as pulleys, couplings and other rotating components that move at high speed are lacking protective covers.
     • The trachea is aging, broken, or the quick joint is loose, and the high-pressure trachea swings violently when the pressure is quickly released.
   • Risk Consequences: Wrap the worker’s clothing and gloves, causing physical injury.
4. Risk risk
   • Risk reasons: Trachea aging, breaking, or the rapid joint loosening, and the high-pressure trachea swings violently when the pressure is quickly released.
   • Risk Consequences: Injure the operator.
5. Noise damage risk
   • Risk reasons: High noise generated when the air compressor is working.
   • Risk Consequences: Long-term exposure to high noise environments will cause damage to the human hearing.
6. Risk Risk of Misuse of Compressed Air
   • Risk Causes: Use compressed air to clean objects, machines, workbenches, clothes, etc.
   • Risk Consequences: Strong airflow or small particles in compressed air can cause personal injury, such as impact damage, explosion damage, etc.

2. Prevention measures for air compressors

1. Prevention measures for fire and explosion
   • Please use low-noise equipment: reduce noise pollution in the equipment itself.
   • Regular inspection and maintenance:
     • Cleaning the oil stains and carbon deposits inside the compressor to ensure the normal operation of the oil and gas separator.
     • Check the effectiveness of the cooling system to prevent the lubricant from thermal cracking due to overheating and forming carbon deposits.
     • Check safety devices such as safety valves, pressure gauges and other safety devices regularly to ensure that they are sensitive and reliable.
   • Strictly abide by operating procedures:
     • Diesel-powered air compressors should take good leak prevention and fire prevention measures.
     • It is prohibited to store flammable and explosive items around the compressor, and no operations such as painting and aluminum-magnesium grinding are allowed.
     • Do not flammable liquid fall into the cylinder, air reservoir and air conduit during repair and installation.
     • Electrical equipment must ensure grounding and zeroing protection, and ensure good and effective. Electrical equipment that is aging, short circuit, and damaged insulation should be repaired in a timely manner.
   • Installing safety devices:
     • Installing an overtemperature and overpressure alarm interlock device on the compressor.
     • The design and operation of the gas storage tank shall comply with the provisions of the “Pressure Vessel Safety Technical Supervision Regulations” and install necessary pressure display and overpressure regulation and alarm systems.
     • Dry filters should be installed before the suction pipe of a large air compressor.
2. Prevention of electric shock
   • Check the electrical system regularly: Make sure the power cord, grounding cord, junction box, etc. are intact.
   • Strengthen electrical safety management: Provide electrical safety training for operators to improve safety awareness.
   • Set warning signs: Set warning signs around electrical equipment and lines to remind personnel to pay attention to safety.
3. Mechanical injury prevention measures
   • Installing protective covers: Install protective covers for rotating components such as pulleys and couplings that move at high speed.
   • Confirm the trachea and joints regularly: Make sure that the trachea is not aging or broken, and the joints are connected firmly.
   • Set warning signs and safety areas: Set warning signs and safety areas in dangerous areas to restrict people from entering.
4. Object strike prevention measures
   • Regularly check the trachea and joints: the same as mechanical injury prevention measures to ensure that the trachea is not aging or fractured, and the joints are connected firmly.
   • Strengthen the training of operators: Improve the safety awareness and operation skills of operators, and avoid illegal operations.
5. Noise damage prevention measures
   • Select low-noise equipment: reduce noise pollution in the equipment itself.
   • Set up sound insulation facilities: Set up sound insulation facilities around the compressor to reduce noise propagation.
   • Equipment of protective supplies for workers: such as noise-proof earplugs or ear cups to reduce the damage caused by noise to the human body.
6. Prevention on misuse of compressed air
   • Strengthen safety training: Provide operators with safety use of compressed air, and it is clearly prohibited to use compressed air to clean clothes, hair and body.
   • Set warning signs: Set warning signs in the compressed air usage area to remind personnel to pay attention to safety.
   • Confirm and maintain the trachea and joints regularly: Make sure the trachea is not aging or brokenThe phenomenon is that the joints are connected firmly to prevent personal injury caused by tracheal burst.

3. Summary

There are many risks in the use of air compressors, but by taking effective preventive measures, these risks can be effectively reduced. Enterprises should establish and improve safety management systems, strengthen equipment maintenance, personnel training and safety supervision, and ensure the safe use of air compressors. At the same time, operators should also improve their safety awareness, strictly abide by operating procedures, and avoid illegal operations.
