Battery production

Battery manufacturing industry electrotechnical industry engaged in the production of batteries. From a hygienic point of view, particular importance is the production of lead batteries, the production of which is connected with the use of lead and sulfuric acid. Individual production processes may be accompanied by a receipt in the air of working premises lead dust that enter the body mainly through the respiratory tract (less than by ingestion) and causing lead poisoning (see Lead).
Prevention: mechanization of production processes, sealing equipment, strict observance of rules of personal hygiene and safety when working with lead. On the battery plants should be periodically conducted medical examinations to detect early signs of poisoning of workers lead, laboratory monitoring of air of working premises. Must be constructed shower room type sanitary inspection, organized separate storage for personal and industrial service, will be issuing a work of soap and towels.

Battery manufacturing industry electrotechnical industry engaged in the production of electric batteries. Material for the manufacture of lead acid batteries are lead, lead litharge, red lead, antimony and sulphuric acid.
In the foundry battery manufacturing plant on the machine are cast lead lattice required for the manufacture of lead plates. In large enterprises, almost all casting processes are mechanized. Foundry unit is equipped with a ventilation system ensuring remove fumes of lead and dust. In the shop of lead powder machines cast lead balls, which are then ground in a ball mills. The mill is equipped with suction unit with installation for cleaning of sucked the air from lead dust before release to the atmosphere. In pastoralisation shop of oxides of lead (red lead and litharge, lead powder) to prepare a paste by mixing sulfuric acid and water. Pasta is cooked in a closed or open faucets. In the first case, the possibility of penetration of lead dust in the working premises is excluded. Open faucets should be thoroughly covered and equipped with exhaust ventilation. To pattanapitoon machines serves lead lattice, in which vyzyvaetsya pasta. Pastamania shops are equipped with dryer. Drying chamber is equipped with suction ventilation. In electrochemical plant formed plate. The process of education on plates by electrolysis of active materials - dioxide of lead and spongy lead - lasts from 24 to 50 hours. Plates are immersed in tanks with sulfuric acid. After forming plates arrive in the separation division, where their mechanical share and smooth out; the emitted dust is removed by local suckers. Of the barrier separating the plates arrive at mechanized Assembly.
Individual production processes A. p. may be accompanied by a receipt in the air of working premises lead dust when working on mixers of an open type in the separation branch), as well as fumes of lead (in the process of manufacturing of lead powder in foundries). In forming the shop, if the bath mirror remains open, acid baths in the air is allocated the smallest droplets of sulfuric acid. Possible burns the body, sulfuric acid, hydrogen flame, and splashes of molten metal.
In the body lead falls mainly in the form of dust through the respiratory tract, less frequently, through the digestive tract. Fine particles are formed by condensation of vapours during the smelting of lead.
When mechanization of production processes, sealing equipment, observance of rules of personal hygiene and safety work with lead and its compounds modern mills is not dangerous for health. Monitoring of the health of workers and periodic medical examinations allow to identify the earliest signs of the impact of lead on the body.
On the battery plants laboratory monitoring of work premises; this provides an opportunity to prevent lead poisoning (see). When individual production processes, where the dust on the technical conditions, it is difficult to completely eliminate, the workers are dust respirators (see).
Of great importance for the prevention of poisoning has observance of rules of personal hygiene. At the enterprises suit shower room type sanitary inspection, organize separate storage of personal and manufacturing service.
