Aluminum manufacturer the dust which produces in the production process mainly has the aluminum oxide dust, the refinery coke dust, the asphalt mist and dust. In aluminum oxide dust main existence electrolysis workshop, aluminum oxide storage and transportation system; After the calcine construction section's high-quality goods system, the dump system, calcine, construction section's kneading machine, the preheating screw machine as well as the scratch system have the dust and the asphalt smoke production; The formation construction section also has the asphalt smoke production; The remnant extreme technical section thick broken, the ingredient, sieves the classification process to have the dust production. The overhead traveling crane driver, the electrolysis workshop worker, the carbon powder stave, sieves the classification post worker to be big the dust hazard. 2. poison harm
The work worker contacts the poison mainly has the fluoride, the sulfide, the asphalt smoke, the carbon monoxide and so on. The poison mainly exists nearby the electric tank and the haze purification system.
The human body inspiration excessive fluorine, will cause fluorine osteopathies frequently and so on osteosclerosis, ossein proliferation, porphyritic tooth, serious causes the human to lose the ability to work. The fluoride also has the intense stimulation and the corrosive action to the respiratory tract mucous membrane and the skin.
The asphalt has two aspects to human body's main harm: First, because in the asphalt contains light feeling materials and so on anthracene, the long time contact, and after the sunlight illumination, may cause dermatitis; Second, asphalt smoke to skin and mucous membrane stimulation.
The carbon monoxide produces in electric tank's anode, the carbon monoxide for the achromatic color, the odorless gas. It creates the organization oxygen deficit in the blood with the hemoglobin union. The mild gas casualty has the headache, dizziness, the tinnitus, the palpitation, disgusting, the vomit, incapable, the arteries quick, to be agitated, shallowly to the moderate stupor; The specific weight patient depth stupor, the pupil reduce, the myo- tensity to strengthen, to twitch frequently, the feces and urine incontinence, the pulmonary edema, the serious cardiac muscle harm and so on.
Also has the sulfide production in the electrolysis process. The sulphur dioxide is the colorless gas, the cross-eye and the respiratory tract mucous membrane has the intense stimulation. When mild poison, the skin either the eye contact has the inflammation or burns; The serious poison may have the pulmonary edema, throat dropsy, the vocal cord convulsion in several hours to send suffocates.
Produces the noise equipment mainly to have the purification system air blower, the carbon system breaker, the ball mill, the shaper, the feeding engine, the shaker, the conveyer and the roasting haze purification system air blower and the dust removal air blower and so on. The noise can cause the person sense of hearing function sensitivity to drop even creates deafness, or causes the neurasthenia, cardiovascular illness to get sick and illness sickness and so on digesting system, the noise effect communication, urges the misoperation formation rate rise.
So long as is silicosis, every year the duty against institute must force the physical examination, moreover the company must have the practical and feasible occupational disease prevention measure, otherwise is very big to worker's health's harm.
