Common occupational and prevention of granite industry

Because natural granite material advantages such as beautiful and durable, has become one of people's favourite construction and decoration materials one, have been widely used in luxury building and into family.

Because of the massive development and use granite, the rapid development of urban and rural granite base many teams, processing an increasingly large. For example of shandong laizhou city and almost flat, whole people all soldiers make granite, and has become a pillar industry in the stone, the current granite vendors and processing teams have been throughout the country.

The author, after retiring, asking for past medical granite, others fun changed his business funny that I "make up the software and hardware". Through years of work, I saw in granite observed in the processing, for youth team laid-off again obtain employment personnel temporary is relatively poor, their lives and culture quality is poor. Only immersed find jobs to make money, and do not pay attention to also won't themselves protection: at the same time, the management of material of granite of private corporations boss, also most cultural water strict and technical quality is poorer, management of water, jot down low, eager for dry conditions are poor horse, labor, equipment humble, technological level, just grab production, health care workers on enough. Now the common diseases of the granite industry, the harms, etiology and preventive measures, some ideas about the same field for reference.

A, pneumonia

Silicosis is long-term inhalation crystallization of the fractal silica (SiO2), lung tissue damage caused by dust, one of the most serious diseases, is most see the earliest occupational disease, research reports. Silicon is the most main crustal rocks with free form element, combines with oxygen into SiO2; It takes tetrahedral crystallization forms and microscopic particles exist, through respiratory tract enters lung tissue forming fibrosis, and constantly fusion nodular sclerosis of normal lung tissue, causing severe decrease, finally the respiratory function obstacle. Early may not have any abnormalities, incidence after often appeared cough, shortness of breath, chest tightness, chest pain, difficulty breathing, emphysema, easy concurrent tuberculosis and lung cancer, etc.

Precaution: the mainest is well, to improve the dustproof job working environment, strengthen ventilated, adopt wet homework, such as drilling to bring water drilling operations, banned dry play; Edge grinding drilling should be changed, dig holes for dry grinding joint; Dust must stand on when working on workers, or wear good indeed upstaged the dust mask mote effect. And suggest granite processing staff regularly performed or x radiograph, find out problems timely photo profession or treatment.

Second, vibration disease

Systemic and local vibration disease points in the latter two, but see more, it is a kind of caused by the body's long-term accept vibration stimulate the occupational disease, such as surface happen one long-term use of various electric tools, marble machine, drilled Angle abrasive machine, pneumatic, electric hammer, driving a tractor etc, can cause acromegaly vasospasm, peripheral nerve feels obstacle, serious can cause paroxysmal purple or pale fingers, hands, hand pain, "mildew's hand stiff's phenomenon".

Prevention measures are: requests the enterprise management and the general workers, and to reform the granite processing equipment and working style, reduce machine violent vibration attention, avoid combining exertion and the noise of the cold collaborative stimulation. Solid for the cold and noise, neural and fluid strengthen function, will promote the development of vibration disease can also strengthen noise, vibration of hearing damage, because this vibration, cold and noise are three interrelated pathogenic factors. Close all should prevent the relationship.

Three, noise disease

In today's world, a variety of noise pollution has become more and more serious, the seven nuisance, millions of people, our country has seriously by noise dry sorrow, tens of thousands of people exposed to can cause hearing damage noise environment, granite industry work, including the noise, such as granite mining waste materials and cutting blasting, and special processing of electric tool vibration noise, can lead to employees "ill from ear into", long-term excessive stimulation, will have headaches, dizziness, tinnitus, hard of hearing, deaf, elevated blood pressure, atherosclerosis and other serious diseases.

Precaution: granite profiles of the blasting away from the scene, updating of the more advanced equipment, selects the noise small granite grinding machine, cutting machine operation run large, workers available ears cover, earplugs, etc the necessary measures.

Four, electrically damaging

granite's many kinds of processing machine like cutting machine, spends line machine, milling machine, drilling machine and a variety of small electric tools, regardless of three-phase electricity or two phase electricity, if use undeserved, lack of elaborate preventive maintenance, or motor water, or cable aging, broken, or use and shoddy products, together with cultural quality is poor, no workers regular security training, hidden dangers many, can appear different degree of shock damage, serious can cause fires and personal casualty, such as in August 1998 Beijing league two market a merchant workers from shandong fei county, just eight days to work of rural, because Angle mill site leakage died in one.

Prevention measures: improved worker culture quality and strengthen education, training learned to use power tools and simple maintenance technology, vigorously promotes the safety of electricity various measures, suit the remedy to the case, minimize the shock casualties accidents.

Five, the granite of selenium wounds and cutting wounds

granite features: heavy, marble, edge sharp, easy rupture, so in transportation, move and machining process, often happen different degree of blunt force trauma and cutting wounds.

Prevention measures: Suggestions carry board to make carry don't flat lift, wear a glove, torre during the work do not wear shoes, handling tools and store shelves to firmly.
