Pneumosilicosis is stalked, cut to masonries
Recently, there are 34 to cut to masonries and suffer from pneumosilicosis one gem craft factory in Guangdong, the person liable of the accident is punished severely, the aftermath costs 4 million yuan. According to the investigation, with the swift and violent development of urban construction, quarry, cut the stone, rubble, grind, polish the new and developing trade of the ornamental slabstone material and arise at the historic moment. Most operators in these trades come from the countryside, they lack the preventive treatment knowledge of occupational disease, what the manufacturer offered is cut the craft operating environment of rubstone ignores hygiene safe protection facilities again, just think of and appear the products more and make money more, endanger regardless of the stone dust. The workers often work extra shifts or extra hours, process production operation in overload, the small Shi dust not understanding the procedure flies upward with the wind will enter one's own lung through the respiratory tract, it will inevitablely cause pneumosilicosis to accumulate over a long period. Exploitation engaged in various mineral depositing, work post of building the road, excavating the tunnel, building water conservancy projects, quarrying crushing, refractory material etc. and ceramics, founding casting, quartz powder field, glass processing,etc. of cutting into a mountain are produced, while the craft is operated, workers may all touch and contain two free dust which oxidize the silicon. The persons who suck have illness coming on and is correlated with denying the density with the dust and size of particle, the higher the density is, endanger the more greatly; The smaller the dust is, more harmful. Pneumosilicosis is sucked, contained whole body disease that two free dust which oxidize the silicon cause by the human body, lung pathological change is particularly outstanding. The onset mechanism is: Includesing two dust which oxidize the silicon will enter and produce machinery to the lung organization amazingly in people's lung on one hand, dissolve gradually on one hand, form poisonous the intersection of silicon and sour colloidal solution, cause the intersection of cell and protein solidify, cause the lymphocytic tube wall or lymphoid tissue inflammation around, therefore stimulate the ring hyperplasia of connective tissue, form tubercle, and then lead to the fact pulmonary emphysema, lung original heart disease, lung function drop, cause workforces to drop or lose finally. The duty prevents the department from being engaged in quarrying, rubble worker's revealing health examination some stone field: The self inductance at various degrees of these people has symptoms such as chest aching, coughing, shortness of breath uncomfortable in chest,etc. frequently, chest block can see the shade density of lung door to increase, increase in the X-ray, even appear symptoms such as the tubercle shade,etc.. The specific patient, still with pulmonary emphysema, original physical sign of heart disease of the lung. Therefore, the ones that specially proposed all parts cut the rubstone homework workshop and should be devoted to thinking about workers, set up the dustproof measure, reform the production operation craft, motorize production equipment, airtight to melt, automize, this is a dustproof essential measure. All it operate craft to should change into on homeworks wet,can't the should last dust absorption devicing of homeworks wet, should also do a good job of the safe protection of the personal hygiene, such as putting on the dustproof gauze mask, mask and job cap, conditional to put on the work clothes. Carry on health examination to workers regularly.
