Kadangi operatoriai da\u017enai b\u016bdavo mobil\u016bs ir dirbdavo ore, jie jau tur\u0117jo siurbimo degiklius. Tuomet juos papild\u0117me „ePur100” galia, kad b\u016bt\u0173 galima surinkti likusius suvirinimo d\u016bmus i\u0161 aplinkos. Operatori\u0173 atsiliepimai buvo patenkinami, nes jiems nebereikia nerimauti d\u0117l sveikatos problem\u0173. <\/p>\n\n

K\u0105 reikia \u017einoti apie suvirinimo d\u016bmus<\/h2>\n\n

Metalo suvirinimo d\u016bmai gali b\u016bti laikomi pavojingais operatori\u0173 sveikatai ir sukelti profesines ligas, priklausomai nuo j\u0173 sud\u0117ties, koncentracijos ir poveikio trukm\u0117s. Rizika kyla ne tik suvirintojams, bet ir aplinkiniams darbuotojams. Prevencin\u0117s priemon\u0117s grind\u017eiamos kolektyvini\u0173 ir individuali\u0173 apsaugos priemoni\u0173 naudojimu. <\/p>\n\n

Kas yra suvirinimas?<\/h2>\n\n

Jungiant metalines dalis, taip pat vadinam\u0105j\u012f metalo suvirinim\u0105, susidaro suvirinimo d\u016bmai. Jie susidaro energijos \u0161altiniu kaitinant skirting\u0173 metal\u0173 kra\u0161tus iki lydymosi temperat\u016bros. Pagrindinio metalo ir u\u017epildomojo metalo mi\u0161inys praskied\u017eiamas, kad susidaryt\u0173 suvirinimo si\u016blelis arba jungtis. Metalo suvirinimas gali b\u016bti atliekamas su visomis metalin\u0117mis med\u017eiagomis. <\/p>\n\n\n\n

Galima naudoti daug suvirinimo proces\u0173, kurie skirstomi \u012f rankinius, pusiau automatinius ir automatinius. Da\u017eniausiai \u012fmon\u0117se naudojamas suvirinimas elektriniu lanku, ta\u010diau yra ir kit\u0173, pavyzd\u017eiui, var\u017einis, dujinis, mechaninis ir didel\u0117s energijos tankio suvirinimas. <\/p>\n<\/div>\n\n\n\n

Kokie yra suvirinimo d\u016bm\u0173 keliami pavojai?<\/h2>\n\n

D\u0117l auk\u0161t\u0173 temperat\u016br\u0173, pasiekian\u010di\u0173 lydymosi ta\u0161kus, visi suvirinimo procesai skleid\u017eia potencialiai kenksmingus d\u016bmus. \u0160i\u0173 d\u016bm\u0173 gali \u012fkv\u0117pti suvirintojai ir gamybos pastatuose esantys pa\u0161aliniai asmenys. Priklausomai nuo proceso, \u0161ie d\u016bmai susimai\u0161o su kar\u0161tu oru ir susidaro \u012fvairios proporcijos dujos ir dulk\u0117s. \u0160i\u0173 dulki\u0173 dydis yra ma\u017eesnis nei 1 mikrometras. Atsi\u017evelgiant \u012f labai ma\u017e\u0105 dyd\u012f, \u0161ios dulk\u0117s gali pasiekti kv\u0117pavimo sistemos alveolin\u0119 zon\u0105. <\/p>\n\n

Tod\u0117l suvirinimo d\u016bmai gali sukelti apsinuodijim\u0105 ir sukelti \u016bmi\u0173 ar l\u0117tini\u0173 sveikatos sutrikim\u0173. Pagrindiniai d\u016bmuose esantys ter\u0161alai yra \u0161ie: <\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t

Kaip galite i\u0161vengti rizikos?<\/h2>\n\n

Taikomos atsargumo priemon\u0117s turi b\u016bti pritaikytos ne tik prie naudojam\u0173 proces\u0173 ir med\u017eiag\u0173, bet ir prie darbo vietos (\u012fskaitant dirbtuves ir darbo viet\u0105). Tod\u0117l, prie\u0161 imantis bet koki\u0173 prevencini\u0173 priemoni\u0173, b\u016btina atlikti operatori\u0173 darbo viet\u0173 analiz\u0119. Siekiama surinkti kuo daugiau svarbi\u0173 veiksni\u0173, kad b\u016bt\u0173 galima apibr\u0117\u017eti priemones, kuri\u0173 reikia imtis. Analizuotinos \u0161ios sritys: naudojami suvirinimo b\u016bdai ir parametrai, apdirbami ruo\u0161iniai, operatori\u0173 darbo vietos, biurai ir med\u017eiag\u0173 sraut\u0173 organizavimas dirbtuv\u0117se. <\/p>\n\n

Siekiant suma\u017einti suvirinimo d\u016bm\u0173 kiek\u012f, galima taikyti kelet\u0105 prevencini\u0173 sprendim\u0173, pavyzd\u017eiui, suvirinimo d\u016bm\u0173 surinkim\u0105 j\u0173 susidarymo vietoje ir bendr\u0105j\u012f v\u0117dinim\u0105<\/strong>.<\/p>\n\n

Suvirinimo d\u016bm\u0173 surinkimas prie \u0161altinio yra saugiausias sprendimas operatoriams. Taip sulaikomi i\u0161siskiriantys d\u016bmai ir operatoriai apsaugomi nuo rizikos \u012fkv\u0117pti dulki\u0173 ir daleli\u0173. Vietinis i\u0161traukimas i\u0161laiko ter\u0161alus iki ma\u017eiausios \u012fmanomos t\u016brio dalies ir po filtravimo i\u0161 cecho pa\u0161alina ter\u0161alus. Vietinis i\u0161traukimas sulaiko i\u0161siskirian\u010dius ter\u0161alus prie\u0161 jiems patenkant \u012f operatori\u0173 ir j\u0173 kv\u0117pavimo takus ir (arba) pasklidus po dirbtuves. Galima numatyti kelet\u0105 vietinio i\u0161traukimo tip\u0173, pavyzd\u017eiui, nusiurbiam\u0105j\u0105 nugar\u0117l\u0119, nusiurbiam\u0105j\u012f stal\u0105, gaubt\u0105<\/strong> arba dulki\u0173 surinktuvus<\/strong>. <\/p>\n\n
