Printing production

Printing production (occupational health) - an industry producing all kinds of printed materials (books, magazines, Newspapers, pictures and other). Currently in printing production carried out hygiene and health activities, improving working conditions. Printing production is highly mechanized, typing in the printing is carried out by machines, printing and reproduction of mass magazines produced on machines deep and flat printing. Are also used photo, fotografirovanie processes.
Lead alloys that serve as the material for casting font, replace if possible, zinc and plastic. The intaglio printing benzene, used as a solvent printing inks, replaced by less toxic toluene. Melting and casting of lead Garth is carried out under local exhaust ventilation, pots to melt the Garth all typesetting machines equipped with automatic temperature controls all premises where is melting alloys and casting font equipped with supply-and-exhaust ventilation, production sites are located in a large, square and cubic content areas, in workshops held katomina cleaning with suction dust from typesetting funds.
All these activities have led to the fact that the content of lead and toluene in the air of working premises does not exceed maximum permissible concentrations and almost in the production liquidated professional poisoning.
Of great importance to ensure high productivity in the printing is rational artificial lighting (see), through which ensures the observance of the standards of illumination in all major areas of printing production (LK 1 000 combined with fluorescent lighting, 400 Lux with luminous General lighting, 500 Lux in mixed light bulbs, 200 LK - in General). In jobs that require a high voltage of view, the coverage should be at least 3000 Lux combined with fluorescent lighting, 750 Lux with luminous General lighting, 1500 Lux in mixed light bulbs and 400 LK - when General. Working on printing production shall be subjected periodically to medical examinations.

Printing production - the branch of engineering that combines ways printed reproduction of text and illustrations.
In the USSR developed a set of hygienic measures to improve working conditions in printing production: hosting workshops in high, dry and bright adequate space and cubic capacity; lead smelting in boilers under a fume devices; bottling lead alloys under the hood; the equipment of the premises is melting alloy and fonts, forced-air and exhaust ventilation; the device of automated temperature controllers in boilers to melt the metal at all typesetting machines in order to reduce evaporation of lead; monthly thorough cleaning with suction dust from cars, floor and walls; wearing clothes and taking a shower after work.
Concentrations of lead dust in workplaces in various departments and offices of the printing enterprises usually do not exceed the maximum permissible norms (0.01 mg/m3). Benzene, used in the technology of deep printing for dissolving of paints, due to the high toxicity has been replaced by less toxic solvent - toluene. In the air workshops gravure printing, using toluene vapor concentration of the solvent does not usually emission limit value (50 mg/m3).
In addition to this, at the enterprises of the printing industry is the number of measures for occupational health: production introduced photo, fotografirovanie and Fotogalerie machines, lead Garth replaced zinc metal and plastic; in order to prevent the occurrence of noise and vibration printing machine installed on shock-absorbing foundations and floors, struggles with dust and other
In printing production the following rules shall apply lighting set for precision work (see the Light): 3000-750 Lux with fluorescent and 1500-400 Lux with incandescent lighting (tables to parse font, workbenches for dressing matrices); 1000-400 Lux with fluorescent lighting and 500-200 Lux with incandescent lighting (surface type-setting boards bakoulin machine, matrix font foundry machines, correction machine, a hash table, engraving machines, retournai remote, plates on the tables for etching half pans, plates on etching machines, cylinders transfer machines, hand and machine set, control printed production and others).
When using localized and local illumination must be provided with protective angle of not less than 30 degrees, and in the location of the center of lights below the line of vision is not less than 10 degrees.
Lighting of the major production facilities printing enterprises incandescent lamp is carried out with the help of combined lighting with use of separate lamps of local illumination of workplaces, mainly type "alpha" with metal caps, whose inner surface covered with white enamel.
Workplaces in typesetting, stereotyped and print shops are provided with relatively high standards of illumination (200-500 LC). However, this usually occurs reflected blizkosti, as incandescent filament lamps inevitably give mirror reflection from the surface of the metal. To mitigate blizkosti in caps insert a light-diffusing glass.
