Uranium production

Electrical manufacturing industry, which produces lighting bulbs, tubes, electrovacuum devices and electron-beam tube.
Lamp production consists of: 1) the manufacture of electrodes, 2) degreasing them with acid, alkali, acetone, trichloroethylene, 3) the coating of the electrode oxides (mixture carbonate, barium and strontium with ethyl and methyl alcohol), 4) application to electrodes of corundum in methanol.
In the production of fluorescent tubes and cathode ray tubes (CRT uses different phosphors, that stands out dust phosphor. Welding of tubes and pipes produced by gas torches. Work on air exhaust from lamps and tubes and filling them with mercury accompanied by release into the air of mercury vapor, and with semi-automatic pumping and pouring of mercury. At the enterprises of uranium manufacture of non-compliance with rules of labour protection and safety of possible cases of chronic poisoning from exposure to vapors of mercury (see) and acute poisoning from trichloroethylene. First aid in case of poisoning trichloroethylene is immediate removal of victims to fresh air and provide oxygen (alternating every 15-20 minutes Carbogen inhalation).
Health activities. Working with trichloroethylene must be performed in a fume hood with mechanical draught or baths with the on-Board suction and cooling. Production of oxides should be in sealed equipment, and the application of oxides on the tables with the on-Board suction. Spray extraction, the work should be carried out in flueblocks. When Strait mercury - immediate cleaning it. In the manufacture of fluorescent lamps must meet the requirements of "Temporary sanitary rules on the device, equipment and maintenance of plants (shops)manufacturing phosphors and fluorescent lamps". A large number of those working in uranium production are granted additional leave.

Lamp manufacturing industry producing electro-vacuum devices: radio tubes, incandescent, fluorescent, rectifiers and electron-beam tube.
The main disadvantages for workers, uranium production are the following. In the plant of refractory metals harmful dust tungsten, molybdenum, tantalum or aerosol condensation of these metals; most intensively these toxic substances are released during loading and unloading reactors and furnaces, grinding, preseve and forging. In the composite plants for crushing, ProSafe, weighing, transportation of sand, dolomite, sodium nitrate, red lead (the elements of glass) can affect the dust of these substances. Furnaces, glass hall, workers are exposed to high temperatures and vapour of lead in the production of lead glass. In chemical plants use a variety of solvents (trichloroethylene, methanol, butyl acetate), and flammable substances (barium, strontium, cerium and their derivatives). The Assembly of the electrodes and installation of small-size vacuum products carry significant stress of view, therefore, important hygienic importance is the lighting of workplaces, and painting of equipment and premises.
In the manufacture of cathode-ray tubes and mercury lamps of DRL lamps are different brands of phosphors which in the process of crushing, weighing and prosea can be a source of dust, air polluting industrial premises. These contaminants can cause the working pneumosclerosis.
The build process of vacuum products is to build devices and vacuum treatment (pumping, filling devices, inert gases, and in some cases in the production of fluorescent and discharge lamps - mercury filling). The main and most serious hazards are mercury vapour contained in the air of industrial premises due to pollution sex and equipment drops of mercury for pumping, the content of the lamps, as well as in the result of the battle of finished products (see Mercury as industrial poison).
Health activities. All work with solvents should be mechanized and be carried out in flueblocks with the lowest exposed workers openings. Particular caution should be observed when working with methanol (see Methyl alcohol). All work with strontium, barium, cerium should be conducted with the observance of fire safety, without the use of metal items, and all containers must be glass or porcelain. Technological processes, accompanied by the release of a large amount of dust (refining, sifting, weighing, transportation), should be as mechanized workshops are equipped with powerful ventilation systems.
