How to check whether got pneumoconiosis?

summary

Many mine workers often come into contact with productive dust and worry that they are suffering from pneumoconiosis. But usually the work is busy, and the hospital examination cost is high. Considering the time and money problems, there is no way to often go to the hospital for examination. How to check whether got pneumoconiosis? Next, I'd like to share my views with you.

How to check whether got pneumoconiosis?

In the early stage, the patients were in good condition, but in the late stage, they were in poor nutrition. Rales can be heard in the lungs of advanced patients, especially when complicated with tuberculosis or pulmonary infection. There are emphysema, pneumothorax, pulmonary heart disease, can appear the corresponding signs. When there are clubbing fingers, we should pay attention to the possibility of other complications.

The X-ray appearance of typical silicosis caused by exposure to quartz dust, especially by inhalation of high concentration quartz dust, is that small round shadows appear in the upper lung fields at first. Both sides are symmetrical, especially on the outside. But the apex of lung is not involved. If the apex of lung has shadow, it is more likely to be complicated with tuberculosis.

In severe cases exposed to high concentration of quartz dust, calcification of silicon nodules may occur after central necrosis of silicon nodules, often accompanied by eggshell calcification of hilar lymph nodes. After the appearance of calcification, the condition often becomes mild and stable for many years.

matters needing attention

1. Process reform and innovation of production equipment are the main ways to eliminate dust hazards. 2. wet operations: wet grinding quartz, refractory materials, wet rock drilling, underground transportation spray spray. 3. Airtight, ventilation and dust removal: for places where wet operation cannot be adopted, airtight ventilation and dust removal method shall be adopted to prevent dust from flying.
