Emergency measures for dust accidents

Productive dust is formed in industrial and agricultural production and is capable of floating solid particles in the air for a long time. In the process of producing and using cement, it is often necessary to contact a large amount of cement dust. If it does not pay attention to protection, it is harmful to the human body. Therefore, constantly improving labor conditions, protecting the safety and health of employees, achieving safe production and civilized construction are an important measure to ensure the completion of production tasks, and an important symbol of corporate management.
First, the classification of dust Inorganic dust. According to different sources, it can be divided into: metal dust, such as aluminum, iron, tin, lead, manganese and other metals and compound dust; non-metallic mineral dust, such as quartz, asbestos, talc, coal, etc.; artificial inorganic dust, such as cement , glass fiber, emery, and so on.
1. Organic dust. Can be divided into: plant dust and animal dust.
2. Synthetic material dust. Mainly seen in plastic processing. In addition to the polymer, the basic ingredients of plastics also contain fillers, plasticizers, stabilizers, pigments, and other additives.
Second, the opportunity to contact In a variety of different production sites, you can access different types of dust. In construction and industry, the main contact dust is free silica, quartz mixed dust, limestone, clay, volcanic mud, shale and iron powder, coal, slag, gypsum, sand, diatomaceous earth and so on.
Third, dust hazards 1. According to different characteristics, dust can cause various damage to the body. If soluble toxic dust enters the respiratory tract, it can be quickly absorbed into the bloodstream and cause poisoning; radioactive dust can cause radiation damage; some hard dust can damage the cornea and conjunctiva, causing corneal opacity and conjunctivitis; dust blocking Sebaceous glands and mechanically irritated skin can cause acne, pyoderma and skin chapped, etc.; dust enters the external auditory canal mixed with sebum, and can form cerumen and so on.
2. Dust most harmful to the body is respiratory system damage, including upper respiratory tract inflammation, pneumonia (such as manganese dust), lung granuloma (such as silica dust), lung cancer (such as asbestos dust, arsenic dust), pneumoconiosis (such as silica Dust and other occupational lung diseases.
3. Pneumoconiosis is a disease mainly caused by diffused interstitial fibrosis in the lung caused by long-term inhalation of productive dust in the production environment. It is the most widespread and most harmful disease in occupational diseases.
Fourth, prevention 1. Leather: that is to actively deepen the process reform and technological innovation, to substantially reduce the production of dust, which is the fundamental way to eliminate dust hazards.
2. Water: Wet operation prevents dust from flying and reduces the concentration of dust in the environment.
3.Wind: Strengthen the ventilation and ventilation measures. Based on the airtight and semi-closed dust emission sources, use the partial extraction mechanical ventilation to extract the dust-laden air from the working face and use the local delivery type mechanical ventilation. Feed fresh air into the work surface.
4. Density: The dust-generating source shall be sealed. The dust-generating equipment shall be covered as closely as possible, combined with the exhaust air, and discharged into the atmosphere after dust removal.
5. Protection: Do a good job of personal protection. After working on dust and poisonous workers, you must bathe and change your clothes to prevent them from taking home dust.
6. Pipes: To strengthen management, personnel engaged in dust operations must wear gauze masks, and even wear filter dust masks. Employees exposed to benzene and high manganese must wear oxygen-type or air-breathing gas masks.
7. Check: Regularly check the concentration of dust in the ambient air, and contact persons should conduct regular physical examinations. Where there are patients with diseases that are not suitable for a harmful operation, they should promptly change jobs.
8. Teaching: Strengthen publicity and education. Educators must not smoke or eat food in hazardous workplaces. They must wash their hands after classes before meals to prevent harmful substances from entering the body with food. Strengthen health education and education, to harmful workplaces, every day to do a good job in cleanliness.
