Painting works

Painting works (occupational hygiene in the shops of the industrial enterprises) - preparation of surfaces to dyeing (removing old paint mechanical or chemical means, degreasing, primer) and applying them to whitewash or paint. Colouring make brushes, spraying, in an electrostatic field and so on
In the production of painting the air of working zone may be contaminated with plank beds organic solvents (see Solvents, Aromatic hydrocarbons), dust paints containing lead (see). Working may be exposed to noise, vibration and ionization. Most adverse working conditions can occur when spraying the paint, particularly of paints containing lead compounds.
For prevention of occupational diseases and poisoning paint shop should be equipped with exhaust ventilation, to paint small details required in flueblocks, medium and large, in a special spray booths with exhaust ventilation. At colouring of large-sized products are equipped with exhaust from places of colouring (using movement of the air handling unit or coated products). To test the effectiveness of ventilation is necessary to periodically perform research work premises on the content of solvent fumes colorful dust and lead. At low concentrations of vapours of solvents for workers ' protection use filtering gas masks, at high concentrations - insulating hose gas masks when working in closed containers and compartments - respiratory apparatus of the AAMWU and the spacesuit Sidyakova, to protect from dust containing lead compounds- respirator (see). At painting works it is used clothing made of cotton with vinyl chloride or silicate-casein coating. The washing of clothing should only be performed at special enterprises. To protect exposed areas of the skin apply protective ointments and pastes (see Paste protective).
During breaks in the work of painters should wash your hands with warm water and soap after work to take a shower. Be sure to brush your teeth. When working with lead compounds wash hands with 1% solution of soda. Painters are preliminary and periodic medical examinations and health training. Pregnant and lactating women with painting works temporarily transferred to another job. Persons under 18 in painting works with organic solvents and lead compounds are not allowed.

Painting collection of painting works, including preparation of surfaces to dyeing (degreasing, removing of old paint, putty and other) and paint application (priming, painting, varnishing) on the surface of the walls, machines, of various products. Removal of old paint and cleaning of metal surfaces produce chemical or mechanical means, using the remover of solvents, alkaline paste, etching, scrapers, cutters, abrasive jet way, firing and other Colouring make using brushes, spray guns, dipping into the paint, using electrostatic field, method of vortex spray and other
Painters can be exposed to vapours of organic solvents (see), colorful aerosol dust polymers, products of their thermo-oxidative degradation, lead compounds (see Lead), noise, vibration, ionization. The concentration of toxic substances in the air depend on the how to paint or remove it, the dimensions of products, availability of effective ventilation organization of the process and the composition of paint and varnish materials. The main source of pollution of the air of working zone and a cause intoxications are organic solvents that evaporate during painting and drying of the product.
Of pigments of the greatest importance of lead compounds (crowns, red, green); powder colouring they are in the paint aerosol, when removing old paint containing lead and grinding into the air in the form of dust. Film formers (tar, asphalt, bitumen and others) may have photosensitizing properties.
At colouring of using synthetic paints: enamel (pentaphthalic, glyptal, perchlorovinyl and others), varnishes (bitumen, coal-oil, epoxy, silicone and other), soils and putty. These materials usually contain organic solvents - white spirit, toluene, xylene, solventnaphta, chlorobenzene, alcohols, ether, acetone, turpentine and other Most toxic of them believe hydrocarbons aromatic series (see Aromatic hydrocarbons).
Under unfavourable conditions of employment of staff with long experience possible functional changes in the nervous system (on the type of vegetodystonia, asthenovegetative syndrome), in peripheral blood (lakopenia, thrombocytopenia, lymphocytosis. When exposed turpentine, toluene, xylene the celebrated painters skin diseases (dermatitis, eczema).


Health activities. Use of new types of paints - water, emulsion polyvinyl acetate - allows in some cases to avoid the use of organic solvents. Essential: hygienic standardization of paint and varnish materials with a decrease in their toxic substances or their substitution by less harmful; rational ventilation of the workplace; proper organization of technology and the personal hygiene of painters. Painting workshops are equipped with mechanical supply and exhaust ventilation. Painting small parts is made in special cabinets-cameras with local exhaust ventilation. Powder colouring of medium - and large-sized products, as a rule, is carried out in special painting chambers; the painter is on working site in the flow of incoming fresh air. At colouring of large-scale products (such as cars) ventilation is often made based on the principle of ventilation limited portion of products. Of great importance are the correct working posture painter and direction of the flow of paint, excluding an opportunity of passage of harmful substances in significant concentrations over the area of his breath. At painting works inside the tanks, compartments, and so on, in addition to mechanical ventilation, use of individual protective insulating means of respiratory organs of workers. Painting in electrostatic field is carried out with remote control outside the camera. With proper organization of labour and rational mechanical ventilation with extraction, from painting and drying units possibility of contamination of the breathing zone of the worker, his clothes and skin toxic substances insignificant. The process of painting in electrostatic field is accompanied bipolar ionization of the air, and so shall be provided for the necessary protection of painters.
Each party received a paint and varnish material must have technical passport for the names of solvents and percentage of them in the mix. This is essential, as in the manufacture of paints possible wide interchangeability solvents with different toxic-hygienic value. About presence in pigments more than 1 % of lead compounds specifies the labelling on the packaging of paints: contains lead compounds".
To prevent intoxication painters should wash your hands with warm water and soap during breaks and enjoy a warm shower after work; be sure to brush your teeth, wash the hands of 1% solution of soda (when working with lead compounds), and to apply protective pastes and gels (PM-1, HIOT 6 cream "Silicone"). It is necessary to work in the clothing, wash which are produced at enterprises. To protect against vapors of solvents used masks grade "a" or respirators f-46. When powder colouring of use of the isolation device with forced air supply in the zone of breath painters (mask IGOS-49 VNIIBT, hose self-contained breathing apparatus), in contact with dry dust of lead compounds - type respirators "Petal" (see Respirators).
Painters have to undergo preliminary and periodic medical examinations. Pregnant and lactating women is temporarily transferred to another job. Persons under 18 in painting works with organic solvents and lead compounds are not allowed.
