Recently, social concern of the original Zhengzhou Zhendong abrasive Co. workers Zhang Haichao "lung" event by the media, finally have the final result. Henan city in Zhengzhou Province, "Zhang Haichao incident" coordinate the work leading group reported 28 days, a number of medical institutions and the content of Henan province by the occupation disease prevention expert Zhang Haichao occupation history, can collect existing imaging data and tracking to diagnose the complex after careful scientific, finally in July 26th, Zhang Haichao was diagnosed with pneumoconiosis.

Zhengzhou Zhendong abrasive Co. Ltd. is a major production of non-public enterprises of science and technology for steel ladle bricks, al2o3-mgo-c bricks, high aluminum. 2004 June to 2007 October, during the Zhang Haichao administration it has experienced workers, broken, press the three jobs will be exposed to dust. In 2007 August, Zhang Haichao started, but has been as a cold treatment, then began a long and difficult journey that occupation disease. With the company's workers Zhang Xicai in 2006 November was diagnosed as "pneumoconiosis II + period", but there is no complete work-related injury confirmation, had died.

28, the relevant departments on the matter of the treatment, disposal after the announcement of the results again in the wear industry caused a stir in the dust pollution. Many people have expressed concern that, occupation disease examination requires the employer issued certificate of occupation history, occupation health surveillance archives, the occupation health examination, workplace occupation hazards detection over the evaluation data and other evidence can be identified, which itself is a high polluting enterprises can take advantage of loopholes, and the reality is employers are willing to "self incrimination", therefore, in this regard, the vast majority of occupation disease is difficult to found. Although the government has introduced a "occupation disease prevention law" and relevant regulations, but the government's lack of investment, no census, and enterprises mainly focus on the development of economy, to protect the health of workers is not paid enough attention.

It is understood, pneumoconiosis in the occupation activity is due to long-term inhalation of the production of dust (dust), and in the lungs caused by pulmonary interstitial fibrosis (scarring) of systemic disease, the incidence of the disease is slow, generally 5-10 years, the elderly up to 20 years. In China there are more than 200000000 people are threatened and occupation disease harm, and pneumoconiosis in all kinds of occupation disease accounted for 80%. Spread to the large number of pneumoconiosis, and cannot be cured, the consumption of social resources is much higher than mine sudden disaster.

Pneumoconiosis is harmful to our health workers the most serious occupation disease. In our country the legal pneumoconiosis has the following twelve types: silicosis, coal worker's pneumoconiosis, electricity, carbon ink, ink pneumoconiosis pneumoconiosis pneumoconiosis pneumoconiosis, cement, talc, mica, kaolin pneumoconiosis pneumoconiosis pneumoconiosis, welder pneumoconiosis, aluminum casting pneumoconiosis.

According to health department statistics, as of the end of 2006, the national total report of occupation disease in 676000 cases, the cumulative incidence of more than 61 cases of pneumoconiosis. The main industry of the disease prone and the types of work are: 1, mining: all kinds of metal mine mining, coal mining and coal mining excavation and other metal mines, is the main operation environment of pneumoconiosis, the main works are drilling, blasting, pillar, transportation; 2, metal smelting, ore crushing screening and transportation; 3, casting manufacturing mechanism with sand, molding, casting, sand blasting and welding work; 4, building materials industry, such as refractory materials, glass, cement, stone production in mining, crushing, grinding, screening, mixing, etc.; asbestos mining and textile transportation 5;, roads and railways, water conservancy construction in tunnel blasting, etc.. Since the 50's of last century, China has more than 14 people died in the occupation of pneumoconiosis, each year about 10000 new cases, these data are the first in the world.

Chinese cement cement reminder and related industries and enterprises, in order to avoid a similar "lung" incident tragedy, guarantee the rapid, healthy and stable development of enterprises, please be sure to take the following precautions: 1, the process of reform, innovation of production equipment: is the main way to eliminate dust hazard. 2, wet operation: the wet milling quartz, refractory material, wet drilling, underground transportation mine sprayer. 3, closed, ventilation, dust: take place not on the wet operation, should adopt closed exhaust dedusting method, prevent dust. 4, dust workers health examination: including pre employment and regular health examination, from dust exposure should also do homework check dust removal. 5, personal protection: wear protective gear such as dust, dust, air safety helmet, helmet air masks. In addition, the pneumoconiosis patients should be removed from the dust and timely, comprehensive treatment according to the condition, active prevention and treatment of tuberculosis and other complications, to alleviate the symptoms, delay the progress of the disease, improve the quality of life!
