getting close to the air compressor

The air compressor itself is dangerous

  1. Due to the oxidative properties of air, especially at higher pressures, the delivery system has a higher flow rate, so the danger of the system is not only the danger of oxidation (heat), but also the danger of high-speed wear and friction. Because the cylinder, air receiver, and air delivery (exhaust) pipeline of the compressor may explode due to overtemperature and overpressure, the mechanical temperature of each component of the compressor should be controlled within the allowable range. Why are many people afraid of getting close to the air compressor?
  2. Atomized lubricating oil or its decomposition product mixed with compressed air can cause an explosion.
  3. Compressor oil seal and lubrication system or air inlet gas does not meet the requirements, so that a large amount of oil, hydrocarbons, etc. enter and deposit in low-lying parts of the system, such as flanges, valves, bellows, variable diameters, etc., under the action of high-pressure gas , is gradually atomized, oxidized, coked, carbonized, and decomposed, becoming a potential condition for explosion.
  4. Humid air, irregular cleaning of the system, and alternating hot and cold operations may cause rust on the inner wall of the pipe, which will peel off under the action of high-speed gas and become an ignition source.
  5. Instability and surge state during air compression can cause a sudden rise in medium temperature. This is the result of the local adiabatic compression of the fluid (air) in the system under sudden action.
  6. During repair and installation work, flammable liquids such as wipes, kerosene, gasoline, etc. fall into the cylinder, air receiver and air duct, which may cause an explosion when the air compressor is started.
  7. The mechanical strength of the compressed part of the compression system does not meet the standard.
  8. The compressed air pressure exceeds the specification. All of the above situations may lead to air compressor failure or air compressor explosion accidents.

Risk of human injury caused by air compressor

  • The risk of air compressor injury to the human body mainly includes:
    • The head of the air compressor, the oil tank, etc. are hot and easy to burn people;
    • The high pressure in the air storage tank of the air compressor may cause injury to personnel;
    • Sudden start of the air compressor during inspection and maintenance may easily cause equipment and personnel injury. In fact, the above risks to the human body come from the characteristics of the equipment, which can be avoided as long as the working regulations are strictly followed.
  • There are also risks from the misuse and lack of vigilance of compressed air. For example, it’s never a good idea to use compressed air to blow dirt off your clothes or in your workplace.
  • Many people know that using compressed air to clean up debris or clothing can cause injury, but it is still used inappropriately because of old bad habits and the convenience of compressed air in the workplace. However, it must be remembered that using compressed air to clean objects, machines, workbenches, clothing and other things is dangerous and that strong drafts or fine particles in the compressed air can cause personal injury.
  • The compressed air pressure used by compressed air tools in the workplace is about 0.6-0.8MPa, which is equivalent to 3-4 times the pressure of a fully inflated car tire. Therefore, although compressed air is a very useful energy source, if it is not used correctly or for the wrong purpose, it can easily cause serious injuries and disasters.

 Air compressor explosion will cause fire

  1. Impact damage
  2. Depending on the pressure, compressed air can wash away small particles of ash that can get into the eyes or scratch the skin. The extent of possible damage depends on the size, weight, shape, composition and velocity of these blown particles.
  3. Compressed air itself is a seriously hazardous source. In extreme cases, compressed air can enter the bloodstream through skin wounds or open tissue in the body. In medicine, air bubbles in the bloodstream act like thrombi, causing dangerous blockages of blood flow. Blood clots in arteries can cause coma, paralysis, or death depending on their size, duration, and location.
  4. Under 40psi (about 2.7 standard air pressure) pressure from 4 inches (about 10 cm) from the ear can blow the eardrum or cause brain damage. Under the pressure of as little as 12psi (about 0.82 standard air pressure), the eyeball can be blown out of the eye socket. Compressed air can even blow through clothing and into the navel, causing the intestines to burst. Blow straight into your mouth, the compressed air can crack your lungs.
  5. Explosion damage Compressed gas has energy, and if it breaks, it will leak quickly, which may cause a gas explosion. When the hose is compressed, the high-pressure air suddenly rising in the hose will cause the hose to bounce, causing eye and face injuries to the operator.
