    The harm of dust to the human body can cause different lesions according to its physical and chemical properties and the amount of dust entering the human body. Such as respiratory system diseases, local effects, toxic effects, etc.

    There are four manifestations of occupational respiratory diseases:

    1.Pneumoconiosis. Pneumoconiosis refers to a disease mainly caused by fibrosis of lung tissue caused by inhalation of productive dust during the production process.

    Due to the difference in the quality and quantity of inhaled dust, there are different degrees of harm. There are many types of pneumoconiosis, 12 of which are classified as occupational diseases, they are: silicosis, coal workers' pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestososis, talc, cement pneumoni, mica pneumoni, potter's pneumoconiosis, aluminum pneumoconiosis, electric welding mixed pneumoconiosis, caster pneumoconiosis.

    2.Dustiness.

    After inhalation of some metals (iron, barium, tin, etc.) dust, it can react with foreign bodies in lung tissues and continue to be slightly fibrotic, but it is less harmful to the human body, and the lesion can gradually subside after being removed from the dust operation.

    3.Lung lesions caused by organic dust.

    Different organic dusts have different biological effects, such as causing bronchial asthma, cotton dust, occupational hypersensitivity pneumonitis, mixed pneumoconiosis, etc.

    4.Tumors of the respiratory system.

    The local effect of dust refers to the action of dust on the mucosa of the respiratory tract to cause atrophic lesions; In addition, pharyngitis, laryngitis, tracheitis, etc. can also be formed; It can form acne, folliculitis, pyoderma, etc.; Metal and abrasive dusts can cause corneal damage, resulting in corneal dysesthesia and corneal opacity; Asphalt soot can cause photosensitive dermatitis when exposed to sunlight. The poisoning effect of dust refers to the poisoning phenomenon caused by inhalation of toxic dusts such as lead, arsenic, and manganese.

    For the hazards of dust, the following technical measures can be used to prevent dust in the production process:

    1.Innovation.

    Reforming process equipment and process operation methods and adopting new technologies is a technical measure to completely eliminate dust pollution and do a good job in dust prevention. In the process reform, the first should be the root cause of the dust hazard in the production process, and then the measures to eliminate or reduce the harm of the dust through treatment.

    2.Wet dust protection.

    It's a simple, cost-effective and effective way to prevent dust. Dust is easy to absorb, coagulate, and increase weight after encountering water, which can greatly reduce the generation and diffusion of dust and improve the air quality of the working environment.

    3.Seal the dust source.

    The effective closure of the dust source is an effective technical measure to prevent dust from escaping, and it is often used in conjunction with ventilation and dust removal technical measures.

    4.Ventilation and dust removal.

    This is the most widely used and most effective technical measure in industrial production. Ventilation and dust removal is to effectively control the dust source by ventilation, and extract the dust-containing gas, which is purified by the dust collector and discharged into the atmosphere, so that the dust concentration of the air in the operation area meets the requirements of the health standard, and the exhaust gas meets the requirements of the emission standard.

    5.Personal protection.

    This is a complementary measure. Usually on the basis of other technical measures, various protective equipment (such as masks, dust masks, dust masks, dust helmets, etc.) is used to further prevent the inhalation of dust and reduce the danger of dust to the human body.

    In modern society, although the standard of living is constantly improving, but with the continuous development of industrial products, the environment in which people live has also been seriously polluted, many projects, in the process of production, will produce a large amount of dust, these dust float in the air, and the body contact with these dust, will have a great impact on the body.

    Leads to poisoning. Different types of dust cause different hazards to the body, if the body inhales some soluble dust, then the dust will enter the body through the blood system, which can cause poisoning, and may also endanger the life of the patient.

    Damage to the cornea, in the process of contact with dust, if some hard dust once it comes into contact with the eye, it will damage people's cornea and conjunctiva, tissue, in this case, it will lead to the symptoms of corneal opacity, and may even cause conjunctivitis, so we must pay attention to it, and try to stay away from these dusts.

    Pneumoconiosis is caused by the body after inhaling a large amount of dust, which is mainly caused by long-term living in a dusty environment, resulting in changes in the diffuse interstitial fibers of the lungs. Pneumoconiosis is a relatively common occupational disease, which will have a great impact on the health of the body, so everyone should wear a mask as much as possible when living and working.

    Affecting the health of the powder, after it has been in contact with the skin, it will have an adverse impact on the health of the skin, and may even clog the pores and may also cause the problem of dryness.

    Dust will cause a lot of harm to the health of the body, we must have a correct understanding and understanding, in daily life to try to avoid these dust, if you have to work in this environment, then we must do a good job of relevant protective measures, as far as possible to wear eye masks and masks, so as to reduce the adverse effects of dust on the body.

    The main hazards of dust to the human body include bronchitis, severe can cause pneumoconiosis, obstructive emphysema, respiratory failure, and cor pulmonale. Under normal circumstances, the nasal cavity, nasal mucosa, and bronchial cilia have a certain filtering effect on dust particles with large diameters in the gas, but for dust with a diameter of less than 5 microns, it can diffuse into the lower respiratory tract and be deposited in the bronchial mucosa, and will form pneumoconiosis nodules after being engulfed by macrophages for a long time, and form plaques with the development of the disease, affecting the function of lung diffusion and ventilation.

    Dust refers to solid particles with a small diameter, which can be naturally generated in the natural environment, such as dust produced by volcanic eruptions, or can be generated by various activities in industrial production or daily life, such as a large number of dust particles produced by rock crushing in the mining process. Production dust refers to solid particles that are formed during the production process and can float in the air for a long time. After the formation of many production dusts, the surface can often adsorb other gaseous or liquid harmful substances, becoming the carrier of other harmful substances. Productive dust pollutes the working environment and affects the physical and mental health of workers.

    1. Systemic damage: Long-term inhalation of higher concentrations of dust can provoke systemic diseases (pneumoconiosis) dominated by overflowing and progressive fibrosis in the lungs; If toxic dust is inhaled, it can be ablated on the bronchial wall and received, and carried from the blood to all parts of the body, causing systemic poisoning and severe damage to the central nervous system, respiratory system and digestive system. Similarly, there are also hazards in the paint mist produced by spray painting, so the spray paint mist treatment work also needs to be done well!

    2. Part of the damage to contact or inhalation of dust, the initial effect on the occurrence of **, cornea, mucous membrane, etc., and a series of lesions. If the dust effect is on the respiratory tract, it can cause hyperfunction of the nasal mucosa and telangiectasia in the early stage, which will constitute hypertrophic rhinitis over time, and finally atrophic rhinitis due to the lack of mucosal nutrient supply. It can also constitute pharyngitis, laryngitis, trachea and bronchitis. The effect is **, can constitute acne, folliculitis, pyoderma, such as lead dust immersion**, will present some small red spots, called "lead rash" and so on.

    3. Carcinogenesis induces dense exposure to dust such as nickel, chromium and chromate, which can cause lung cancer; Exposure to radioactive mineral dust can easily cause lung cancer; Asbestos dust can cause skin cancer.

    People who work in widespread, persistent dusty environments are physically hazardous. This is because dust is solid particles with a very small diameter that can be inhaled through the respiratory tract and deposited in the lungs. If you work in such an environment for a long time, the productive dust in the lungs will be inhaled more and more for a long time, and the deposition in the lung tissue will cause a wide range of lung inflammatory reactions, such as pneumoconiosis, silicosis, and diffuse fibrosis of the lungs for a long time.

    Moreover, lung function will decline, causing dyspnea, and even respiratory failure in severe cases, which will affect the normal life and work of individuals.

    First, it has the greatest impact on the first, although there is protection, but the dust is still easy to be absorbed by the first. For example, it is easy to absorb during sweating or after sweating, causing itching.

    Second, if the protection is not enough to injure the trachea and lungs through the nasal cavity, the trachea will become inflamed at least and the lungs will be suffocated at worst.

    Thirdly, if the protection is not well received through the oral cavity, it can lead to stomatitis and even gastrointestinal diseases.

    The harm of dust is very large, if inhaled into the body, it will bring us different degrees of damage and cause different degrees of lesions, especially the respiratory tract is more common.

    1.First of all, there will be varying degrees of pneumoconiosis. Long-term inhalation of dust can cause fibrosis of lung organs and tissues. The severity of the disease is determined by the amount of dust inhaled.

    2.There are also some problems with the milder impact of dust, dust-deposition. It will also cause slight fibrosis of the lungs, but the impact on the human body is relatively small, and it will cause lesions of the respiratory mucosa, such as tracheitis, pharyngitis, laryngitis and so on.

    3.Dust sticking to ** will also form some troubles, such as causing **folliculitis, acne, etc., and even inhaling heavy metal dust will also lead to poisoning.

    Therefore, we must stay away from dust in our lives, and we must also take protective measures.

    The harm of dust to the human body, according to its physical and chemical properties and the size of the particles, the amount of the amount of entering the human body and the different parts of the action, can cause different lesions, mainly some lung lesions. Among the respiratory diseases affected, the first common is pneumoconiosis, which refers to the fibrosis of lung tissue caused by inhalation of productive dust in the production process, and the patients are mostly exposed to silica dust 10 15 years after the onset of the disease, the course of the disease is slow, and the respiratory function of patients in advanced severe cases is seriously impaired, often complicated by cor pulmonale and tuberculosis, and the best ** needs to be replaced**.

    It can also lead to the occurrence of asbestosis, which refers to the long-term inhalation of asbestos dust caused by pulmonary fibrosis and pleural fibrosis as the main lesions, and the main clinical manifestations of patients are cough, sputum, shortness of breath and chest pain, etc., and the symptoms and signs of pulmonary dysfunction and chronic cor pulmonale will occur in the late stage.

    If you must work in such an environment, you must take protective measures to avoid the occurrence of diseases.

    The main injury to people is respiratory disease. Due to the different properties of dust, it is generally easy to cause lung inflammation, pneumoconiosis, metal dust deposition, tumors, etc.

    For the sake of personal health, it is recommended to choose a protective mask scientifically.

    The way to clean dust: the scientific selection of dust masks certified by GB2626-2006 standards can help prevent lung damage.

    1. Choose a duplex half mask type. Disposable masks are not suitable for long-term protection due to their high air leakage rate.

    2. Choose KN100 dustproof filter cotton for use. A low rate of protection will lead to physical injury.

    3. It is more comfortable to choose silicone material. It is suitable for long-term wear and is not easy to cause allergic reactions. Masks with high rigidity are prone to facial indentation.

    4. Masks are divided into large and small sizes, which is extremely important. Don't buy masks that are called generic models. Prone to air leakage.

    5. There are two types of masks that cover the mouth and nose, covering the mouth, nose and chin, and it is recommended to use the latter, which is relatively comfortable.

    6. It is recommended to choose a breathing mask. Some masks are designed with double filters, and the filters are double-sided, so that the masks are relatively easy to breathe.
