Prevention of pneumoconiosis: the awareness of pneumoconiosis injury should always be borne in mind

As we all know, pneumoconiosis is a systemic disease dominated by diffuse fibrosis of lung tissue caused by long-term inhalation of productive dust at work. It is the most serious and common occupational respiratory disease in China.

Pneumoconiosis is difficult to cure, with high morbidity, high disability rate and high mortality. The body of early pneumoconiosis patients can compensate, generally without or only slight conscious symptoms; With the progression of lesions and the emergence of complications, there may be different symptoms and signs. The main clinical manifestations of pneumoconiosis patients are cough, expectoration, chest pain and dyspnea, as well as wheezing and hemoptysis; If there is fever, liver enlargement and edema, it may be complicated by other diseases.

"China is the country with the most serious harm of pneumoconiosis in the world. The number of workers exposed to dust, the number of new pneumoconiosis cases and the number of current pneumoconiosis patients all rank first in the world," said Sun Xin, director of the Institute of occupational health and poisoning control of the China CDC.

Relative to treatment, prevention of pneumoconiosis is the top priority!!! In fact, pneumoconiosis is not so terrible. It can be prevented by modern scientific and technological means. According to the national standard gb2626-2006 respiratory protective equipment self breathing particulate matter respirator, we can know that the dust-proof grade can be divided into three grades: kn100, kn95 and Kn90, and the corresponding protection efficiency is

Kn100: protection efficiency ≥ 99.97%

Kn95: protection efficiency ≥ 95%

Kn90: protection efficiency ≥ 90%

With the improvement of protection level, the dust-proof effect is also gradually improved. Among them, kn100 refers to that it can effectively filter non oily particles such as dust, smoke, fog and microorganisms above 75Nm, and the protection efficiency can reach more than 99.97%. In other words, effective protection can meet the protection standard of kn100, and the prevention of pneumoconiosis is not a problem. At present, China can independently produce kn100 grade respiratory protective articles! Therefore, don't take chances, care for your life, and always pay attention to scientific protection.
