Hello!
1. You should be able to go to work, but you should still pay attention to the adoption of dust prevention measures. The pneumoconiosis observation period, also known as pneumoconiosis observation objects, refers to people who have a tendency to develop pneumoconiosis but have not yet reached the national diagnostic standards for pneumoconiosis occupational diseases, and who have not yet reached a certain severity of disease. Regular observation and physical examination are required.
2. How long does it take to get pneumoconiosis?
The onset time of pneumoconiosis varies, which is more related to the type and amount of dust inhaled. Generally speaking, it takes 8 to 10 years for silicosis to develop, 5 to 8 years for asbestosis, 15 to 20 years for coal workers' pneumoconiosis, and 16 to 40 years for aluminum pneumoconiosis.
3. Will you still get pneumoconiosis after leaving the dust industry?
Some people who have been engaged in dust operations for a certain period of time may not develop pneumoconiosis in the future even if they are not found to have pneumoconiosis when they no longer engage in such work. Especially those who have been exposed to high concentrations of rock dust for a long time, such as pneumatic drillers, excavation workers, pioneers, quarryers, etc., may even develop pneumoconiosis decades later. This situation is not uncommon because although the dust environment has been removed, the harmful dust that has been inhaled into the lungs will still have a destructive effect, continue to harm the lung tissue, and gradually form fibrosis.
4. What is the eight-character policy for preventing pneumoconiosis?
Some good experiences have been summed up in dust prevention and dust reduction work, which are "propaganda, revolution, water, density, wind, protection, management and inspection".
1. Propaganda refers to publicity and education. Propaganda should be carried out in accordance with the party's principles and policies. It should not only publicize the basic knowledge of pneumoconiosis and the hazards of dust, but also publicize that pneumoconiosis can be prevented and that it is sufficient for the masses. It is recognized that dust prevention and pneumoconiosis prevention are important matters related to the health of employees and the promotion of production. Strengthening organizational leadership and mobilizing the masses are the key to dust prevention work.
2. Innovation refers to the technological innovation of production processes and production equipment, which is the fundamental way to eliminate dust hazards.
3. Water refers to wet operation, which is an effective measure to prevent dust from flying. It has been widely used in many factories and mines and has accumulated a lot of experience.
4. Sealing refers to sealing the source of dust. All equipment that generates dust should be sealed as much as possible. Sealed equipment should be used in conjunction with local draw-out mechanical ventilation.
5. Wind is to use wind to achieve the purpose of dust removal. Generally, there must be a natural ventilation system in the mine so that the dusty air can be naturally discharged according to the designed lines. Mechanical ventilation can also be used, such as pressure-in local ventilation, which uses a fan to press fresh air into the working surface along the air duct, so that the dusty air can be discharged along the tunnel.
6. Protection refers to personal protection and physical enhancement. The purpose of personal protection is to prevent dust from entering the respiratory tract.
7. Management refers to strengthening technical management, establishing necessary dust prevention systems and dust prevention equipment maintenance management.
8. Inspection refers to the health examination of workers exposed to dust operations, regular dust measurement and supervision inspection of the production environment, etc.
