Welding basa rinosanganisira akawanda maindasitiri minda, welding fume ndeimwe yenjodzi dzinowanzoitika dzebasa rewelding.
Welding fume iri mukuita welding kana simbi yewelding nenhengo dzewelding dzasangana, kana paine kupisa kwakanyanya kwekushisa kwakagadzira rudzi rwehutsi, fume iyi ine manganese dioxide, nitrogen oxides, fluoride, ozone, nezvimwewo, inoyangarara mumhepo. kukuvadza muviri wemunhu.Mushure mekunge vanhu vafemesa utsi neguruva, zvinogona kukonzera dzungu, kutemwa nemusoro, kukosora, kusimba kwechipfuva uye kutadza kufema, etc. Kufema kwenguva refu kuchaita kuti maronda efibrous emumapapu aite maronda, kureva, welder's pneumoconiosis, uye kazhinji anoperekedzwa nematambudziko akadai se. manganese chepfu, fluorosis uye metal fume fever.Kutanga uye kukura kwe welding pneumoconiosis inononoka, ine zviratidzo zvishoma uye zvinyoro mumatanho ekutanga echirwere, uye hapana zviratidzo zvinoziva mufirimu yechipfuva che X-ray.Zviratidzo zvinonyanya kuoneka chikosoro, sputum, kurwadziwa muchipfuva, kuoma kwechipfuva uye kutadza kufema.Pulmonary function tests isingaoneki mumatanho ekutanga, asi sezvo chirwere ichi chichifambira mberi, kukanganisa kwemhepo uye kuchinjana kwemhepo kunogona kuitika.
Welders 'pneumoconiosis inofanira kudzivirirwa nguva isati yasvika, uye mabhizinesi ane chokuita newelding uye welders vanofanira kutora matanho anotevera ekudzivirira njodzi yebasa.
1, Kuvandudza mhepo yebasa.
Kufefetedza kwakakamurwa kuita kufefetedza kwechisikigo uye kufefetedza kwemuchina, iyo mechanical ventilation yekubvisa guruva, detoxification effect iri nani, uye naizvozvo munzvimbo dzine urombo husina kunaka hwemhepo, yakavharwa kana semi-yakavharwa chimiro welding, panofanira kuva nemichina yemhepo yemhepo.Zvinokosha kucherechedza kuti akawanda manual arc welding nzvimbo, kunyanya muzhizha, kana kushandisa mafeni kuti zvakananga kufuridza utsi kufefetedza, izvo zvichaita kuti chiutsi diffusion yose workshop, zvikuru ngozi.
2, Kuvandudza dziviriro yako pachako.
Welding operators vanofanira kushandisa masiki eguruva, pamwe chete neheti, magirazi ekudzivirira, magirovhosi, earmuffs, nezvimwewo maererano nezvinodiwa zvehutano hwebasa;kana uchishanda munzvimbo dzakavharwa kana semi-akavharwa, iwe zvakare unofanirwa kupfeka kushandiswa kwemhepo yekupa masiki.
3, Kuvandudza welding tekinoroji uye welding maitiro uye zvinhu.
Nekuvandudza dhigirii remakanika uye otomatiki yewelding, kuitira kuti anoshanda uye nharaunda yekushanda yakasarudzika, inobvisa zvakanyanya njodzi dzekuita welding pamuviri wemunhu;nekuvandudza nzira yewelding, kuderedza kuvakwa kwezvivakwa zvakavharwa kuvandudza mamiriro ekushanda emushandisi kuderedza welding fume kusvibiswa;panguva imwe chete, kunatsiridza welding rod zvinhu, sarudza isina-chepfu kana yakaderera-chepfu welding tsvimbo, iriwo imwe yeanoshanda matanho ekudzikisa njodzi dzekupisa.
4, Teerera kuongororwa kwehutano hwebasa uye kuongororwa kwenzvimbo yebasa.
Mushandirwi anofanirwa kugara achiyedza uye kuongorora guruva uye njodzi dzine muchetura wenzvimbo yebasa, uye kugara uchiongorora hutano hwevashandi kuti vaone matambudziko nenguva uye kudzivirira nekudzora zvirwere zvepabasa.Kuongororwa kwehutano hwepabasa nekuonekwa kwenjodzi dzepabasa kunofanirwa kuitwa zvinoenderana nemitemo nemirau zvimiro nezviyero.
5, Simbisa dzidzo yehutano hwebasa.
Mushandirwi anofanirwa kuitisa dzidzo inodiwa paruzivo rwehutano hwebasa kune vanoita zvehudhirowa, kuwedzera ruzivo rwekuzvidzivirira, kutevedzera hurongwa hwehutano hwebasa, uye kuita basa rakanaka rekuzvidzivirira.
