Do mechanical lathes get pneumoconiosis?

I can tell you responsibly that you will not get pneumoconiosis when you do lathes, that is, the pneumoconiosis mentioned upstairs is the long-term inhalation of productive dust (dust) in professional activities. If you are worried, you can wear a mask, but it is not necessary for you, if you do the lathe long hair, you must wear a hat to avoid hair involvement, and wear long-sleeved clothes, because the iron filings are hot. As for other labor prevention measures, I don't need to know more than a dozen lathe workers, all of whom are in their thirties and forties, and there is nothing wrong with what you said, please rest assured.

As for the problem of powder produced by casting processing, lathes generally process rotary parts, rarely with cast iron (only end covers and machining allowances are very small in the impression), lathes mainly process shaft parts, no shafts are made of cast iron (crankshafts seem to have QT) Lathes process cast iron and cast iron pulleys

Pneumoconiosis is a systemic disease caused by long-term inhalation of productive dust (dust) during occupational activities and its retention in the lungs, mainly diffuse fibrosis (scarring) of lung tissue.

Pneumoconiosis can be divided into inorganic pneumoconiosis and organic pneumoconiosis according to the different types of dust it inhales. Pneumoconiosis caused by inhalation of inorganic dust during production labor is called inorganic pneumoconiosis.

Pneumoconiosis is mostly inorganic pneumoconiosis. Pneumoconiosis caused by inhalation of organic dust is called organic pneumoconiosis, such as cotton pneumoconiosis, farmer's lung, etc.

China's statutory 12 types of pneumoconiosis are: silicosis, coal workers' pneumoconiosis, electro-ink pneumoconiosis, carbon ink pneumoconiosis, talc pneumoconiosis, cement pneumoconiosis, mica pneumoconiosis, potter's pneumoconiosis, aluminum pneumoconiosis, welder's pneumoconiosis, and caster's pneumoconiosis.

1. Cough The cough of early pneumoconiosis patients is not obvious, but with the development of the course of the disease, patients are more likely to have chronic bronchitis, and patients in the late stage are more likely to have lung infection, which can make the cough significantly worse. Cough is related to the season, climate, etc.

2. Sputum cough Sputum cough is mainly caused by the continuous removal of dust by the respiratory system. Generally, the amount of sputum is not much, and most of it is gray thin sputum. If there is pulmonary infection and chronic bronchitis, the amount of sputum will increase significantly, and the sputum will be yellow and viscous or lumpy. It is often difficult to cough up.

3. Chest pain Patients with pneumoconiosis often feel chest pain, and there is no correlation or parallel relationship between chest pain and clinical manifestations of pneumoconiosis. The location is different and often varied, and most of them are limited. It is generally a dull pain, but it can also be a swelling pain, pins and needles pain, etc.

4. Dyspnea With the aggravation of the degree of fibrosis of lung tissue, the effective breathing area decreases, the proportion of ventilation and blood flow is out of balance, and the dyspnea gradually increases. The occurrence of comorbidities can significantly worsen the degree and rate of development of dyspnea.

5. Hemoptysis is relatively rare, and can cause mucosal vascular damage due to long-term chronic inflammation of the respiratory tract, with a small amount of blood streaks in sputumIt may also increase blood volume due to the lysis and rupture of large fibrotic lesions and damage to blood vessels.

6. Other In addition to the above-mentioned respiratory symptoms, there may be different degrees of systemic symptoms, and digestive function is often reduced.

Generally, you will not get this disease, unless you process cast iron all year round, then you should pay attention, if you only occasionally process cast iron, most of them are processed steel, then there is nothing to worry about.

Dry lathes should not get pneumoconiosis. Pneumoconiosis is a systemic disease caused by long-term inhalation of productive dust and retention in the lungs during occupational activities, mainly diffuse fibrosis of lung tissue. People work in the dust-producing environment for a long time, and inhaling a large amount of harmful dust for a long time can make the lung tissue undergo a diffuse fibrous change like ** "scarring", which can damage the function of the lungs, and in severe cases, the patient can lose the ability to work.

We call these lesions pneumoconiosis. It is a serious occupational disease, which is prone to be complicated by pneumoconiosis bronchitis, bronchiectasis, tuberculosis, emphysema, lung infection and lung tumors, and can be life-threatening due to respiratory and circulatory system failure in the late stage of the disease. At present, there is no best method for pneumoconiosis, and the mortality rate is high.

Due to the different types and properties of inhaled dust, the types of pneumoconiosis, the occurrence and development of lesions are also different. Among the current occupational diseases in China, there are 12 statutory pneumoconiosis. They are:

Silicosis, coal workers' pneumoconiosis, graphite pneumoconiosis, carbon black pneumoconiosis, asbestos pneumoconiosis, talc pneumoconiosis, cement pneumoconiosis, mica pneumoconiosis, potter's pneumoconiosis, aluminum pneumoconiosis, welding pneumoconiosis and caster pneumoconiosis. Many industrial production processes can produce dust and cause pneumoconiosis, so pneumoconiosis is the most widespread and serious occupational disease in China. The main areas of operation in China that produce dust and cause pneumoconiosis are:

1 Mining Mining of various metal mines, excavation and mining of coal mines and mining of other non-metallic mines is the main operating environment for pneumoconiosis, and the main types of work are rock drilling, blasting, pillars, and transportation

2 Crushing, screening and transportation of ores in the metal smelting industry;

3. Sand blending, molding, sand cleaning, sandblasting and electric welding of castings in the machinery manufacturing industry;

4. Building materials industry, such as mining, crushing, grinding, screening, mixing, etc. in the production of refractory materials, glass, cement and stone; asbestos mining, transportation and textiles;

5. Tunneling, blasting, etc. in the construction of highways, railways, water conservancy and hydropower.

The incidence of pneumoconiosis is related to genetic factors.

Regarding the degree of harm of productive dust to workers and the family history and blood type of workers, some people abroad conducted a survey on the dust workers of a refractory factory, and found that some family members did not develop silicosis despite long-term exposure to dust, while some family members with similar dust history all developed silicosis. Workers whose fathers had a history of dust exposure had a higher prevalence of silicosis than those whose fathers did not. Workers whose parents are consanguineously married have a higher incidence of silicosis than those whose parents are not consanguineously married.

These suggest that genetic resistance and susceptibility play a role in the pathogenesis of silicosis. In addition, blood type is also related to the onset of silicosis. Some preliminary studies have found that among the four common blood types, the prevalence of silicosis in dust workers with type O and AB is the highest, followed by type B, and the prevalence of silicosis among family members with type A is the lowest.

Gentlemen, smoking is not much better than my lungs.

Of course, you often need to sharpen your knives and you will inhale a lot of dust. It is recommended to wear a mask while sharpening knives.

To make a machine tool, it is necessary to remove rust and polish the machine tool bed of cast iron. If a grinding machine is used, the coolant of the grinding machine is oily and needs to be protected with KP filters. It is recommended to choose a P100 rated mask.

If it is only metal dust, it is susceptible to metal dust deposition. If grinding is done with a grinding wheel, etc., the grinding wheel will produce dust containing silica due to grinding, which can easily lead to pneumoconiosis.

Because pneumoconiosis is not medical, and seriously affects people's life and quality of life, therefore, there is a dust environment, and a pair of respiratory protection and pneumoconiosis prevention work.

Not all masks protect against pneumoconiosis.

To prevent pneumoconiosis, in addition to doing a good job in dust reduction, closure and other accidents in the working environment, it is necessary for individuals to choose dust masks scientifically.

As a special labor protection product, dust masks must be certified by GB2626-2006.

1. Therefore, when choosing a mask, you should also choose according to the national standard. In the national standard, for dust and oily particles, protective masks are divided into oil-proof (oily smoke, oil mist, dust, smoke, fog, microorganisms, represented by KP) and dust-proof (dust, smoke, fog, microorganisms). For dust protection, there are three levels of protection: KN100, KN95 and KN90.

They represent protection against ultrafine dust and 90% respectively.

2. Masks are divided into disposable and replaceable filter half masks and full masks. For long-term occupational protection use, especially in environments with high dust concentration and heavy smoke and dust, it is recommended to use a replaceable filter cotton half mask, and most of the disposable masks are large and small, and there are relatively few high-grade masks.

3. The mask material is silicone, plastic, etc., the silicone material is relatively soft and comfortable, and the facial pressure is low.

4. It is particularly important that the mask is divided into sizes according to the national standard. Many masks are not semicolonized, and the effect will vary from person to person.

5. There are two types of masks: covering the mouth and nose and covering the mouth, nose and jaw, of which the second type of contact mask is large, with good sealing and low pressure sensitivity.

Don't ignore respiratory protection, using fake and shoddy goods, gauze, towels, etc. as masks, which can easily lead to lung diseases. At present, some common N100 grade dust masks can breathe smoothly while ensuring the protective effect, and they are about one yuan a day, which is affordable for both enterprises and individuals. At present, many harsh environments in China are using N100 dust masks such as 3M8233 and Baoshunan 3201.

Planer The tool or workpiece moves in a reciprocating straight line, and the workpiece and the tool make an intermittent feed movement perpendicular to the main motion. Commonly used planers are: bull head planers, gantry planers and single-arm planers.

If there is dust flying in the working environment, and dust prevention and reduction measures cannot be achieved, it is easy to inhale harmful dust into the lungs, so you may suffer from pneumoconiosis. You can estimate according to your situation, if necessary, you can regularly go to the local occupational hospital or CDC to take a chest X-ray for examination, so as to detect the disease in time.

Even if a planer has been processing cast iron for a lifetime, the probability of developing pneumoconiosis is not high.

Is it a planer for machining? Yes, not at all, because it is mainly iron filings and does not produce small particles.

There is a certain chance that there is too much dust in the working environment of the planer.
