Danger to human health caused by dust
The harm of dust to the human body can cause different lesions according to its physical and chemical properties and the amount of entering the human body. Such as respiratory diseases, local effects, poisoning and so on.
Occupational respiratory disease has the following four manifestations:
1.
Pneumoconiosis pneumoconiosis refers to ji disease that is mainly caused by fibrosis of lung tissue caused by inhalation of productive dust during the production process. There are different degrees of harm due to the different quality and quantity of inhaled dust. There are many types of pneumoconiosis, 12 of which are classified as occupational diseases. They are: silicosis, coal worker pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestos lung, talc lung, tide bar cement lung, mica lung, potter pneumoconiosis, aluminum pneumoconiosis. 3. Welding pneumoconiosis and caster pneumoconiosis.
2.
Dust deposition Some metal (iron, barium, tin, etc.) dust can react with foreign bodies in the lung tissue after inhalation, and continue to slightly fibrosis, but it is less harmful to the human body. After the dust is removed, the lesion can gradually disappear.
3.
Organic dust has different biological effects on lung diseases, such as causing bronchial asthma, cotton dust, occupational allergic pneumonia, mixed pneumoconiosis, etc.
4.
The local effect of respiratory dust refers to the atrophic lesions caused by dust on the mucous membranes of the respiratory tract; in addition, pharyngitis, laryngitis, and bronchitis can be formed; acne, folliculitis, and pustular disease can be formed on the skin; metals and abrasives Dust can cause corneal damage, resulting in dull corneal sensation and corneal turbidity; asphalt fume can cause photosensitivity dermatitis when exposed to sunlight. The poisoning effect of dust refers to the poisoning phenomenon caused by inhalation of toxic dust such as lead, arsenic and manganese.
For dust hazards, the following technical measures can be used to prevent dust during production:
1.
Technological innovation, reform of process equipment and process operation methods, and adoption of new technologies are a technical measure to eliminate dust pollution and do a good job of dust prevention. In the process reform, first of all, measures should be taken to prevent the production process from generating dust hazards, followed by measures to eliminate or reduce the hazards after treatment by generating dust.
2.
Wet dust protection is a simple, economical and effective dust protection measure. Dust is easily absorbed, condensed, and gains weight when it encounters water. This can greatly reduce the generation and diffusion of dust, which is good for the air quality of the operating environment.
3.
The sealed dust source effectively closes the dust source is an effective technical measure to prevent dust from escaping. It is often used in conjunction with ventilation and dust removal technical measures.
4.
Ventilation and dust removal This is a commonly used and effective technical measure in industrial production. Ventilation and dust removal is to effectively control the dust source by ventilation method, and extract the dust-containing gas, purify it by the dust collector, and discharge it into the atmosphere, so that the dust concentration in the air in the working area meets the requirements of hygienic standards and the exhaust gas reaches the emission standard. Requirements.
5.
Personal protection This is a supplementary measure. On the basis of other technical measures, the personnel engaged in dust operations are further prevented from inhaling dust by using various protective supplies (such as masks, dust masks, dust masks, dust helmets, etc.) to reduce the impact of dust on the human body. harm.
