I-Barium iyinsimbi yomhlaba e-silvery-white, ecwebezelayo ene-alkaline eyaziwa ngezindawo zayo ezihlukile kanye nohlu olubanzi lwezinhlelo zokusebenza ezimbonini ezahlukahlukene. I-Barium, enenombolo ye-athomu engu-56 kanye nophawu Ba, isetshenziswa kabanzi ekukhiqizeni izinhlanganisela ezihlukahlukene, kuhlanganise ne-barium sulfate ne-barium carbonate. Kodwa-ke, kubalulekile ukubhekana nezingozi ezingase zibe khona ezihambisana nazoinsimbi ye-barium.
Ingabe i-barium metal iyingozi? Impendulo emfushane ithi yebo. Njengezinye izinsimbi eziningi ezisindayo, i-barium ibeka izingozi ezithile empilweni yomuntu kanye nemvelo. Ukuphatha ngendlela efanele, ukugcinwa kanye nezindlela zokulahla ziyadingeka ukuze kuqinisekiswe ukuphepha kwabasebenzi futhi kuvinjwe noma yimiphi imiphumela emibi ezilwaneni zasendle nasezinhlelweni zemvelo.
Okunye okukhathaza kakhulu ngensimbi ye-barium ubuthi bayo. Uma uhogela umoya noma uwumunyile, ungabangela izinkinga zempilo ezihlukahlukene, okuhlanganisa izinkinga zokuphefumula, ukuphazamiseka kwesisu, ubuthakathaka bemisipha, ngisho nokungahambi kahle kwenhliziyo. Ukuchayeka isikhathi eside ku-barium kungase kube usongo olukhulu empilweni yomuntu. Ngakho-ke, kubalulekile ukulandela imihlahlandlela yokuphepha emisiwe lapho usebenza ne-barium noma noma yiziphi izinhlanganisela zayo.
Ngokuphathelene nezingozi zomsebenzi, insimbi ye-barium ingaba umthombo wokukhathazeka ezilungiselelweni zezimboni, ikakhulukazi phakathi nokukhiqizwa kwayo noma ukucwengwa kwayo. I-Barium ores nezinhlanganisela zivame ukutholakala ezimayini ezingaphansi komhlaba, futhi izisebenzi ezihilelekile ekukhishweni nasekusetshenzisweni kwe-barium zingase zivezwe ngamanani abalulekile ensimbi nezinhlanganisela zayo. Ngakho-ke, okokusebenza okufanele kokuvikela umuntu (i-PPE) kanye nezinqubo zokuphepha eziphelele kubalulekile ukuze kuncishiswe ubungozi.
Ngaphezu kwezingozi zomsebenzi, ukukhululwa kwe-barium endaweni ezungezile nakho kungaba yingozi. Ukulahlwa okungafanele kwemfucuza equkethe i-barium noma ukukhishwa ngephutha kwezinhlanganisela ze-barium kungangcolisa amanzi nomhlabathi. Lokhu kungcola kubangela ubungozi emanzini nakwezinye izinto eziphilayo ngaphakathi kwe-ecosystem. Ngakho-ke, kubalulekile ezimbonini ezisebenzisa i-barium ukusebenzisa amasu okulawula udoti asebenzayo futhi zihambisane nemithetho yemvelo.
Ukunciphisa izingozi ze-barium, izinyathelo ezihlukahlukene zokuphepha zingathathwa. Okokuqala, izilawuli zobunjiniyela ezifana nezinhlelo zokungenisa umoya kanye nezivalo zokuphefumula kufanele zibekwe ukuze kuncishiswe ukuchayeka kwabasebenzi ngesikhathi sokuphatha nokucubungulainsimbi ye-barium. Ukwengeza, izinto zokuzivikela ezinjengamagilavu, izibuko kanye nemishini yokuphefumula kufanele zinikezwe futhi zisetshenziswe ngokufanele ukuvimbela ukuthintana okuqondile noma ukuhogela.
Ukwengeza, izisebenzi kufanele zihlinzekwe ngezinhlelo ezifanele zokuqeqesha nezemfundo ukuze zandise ukuqwashisa kwazo ngezingozi ezingase zibe khona ezihlobene ne-barium. Lokhu kuhlanganisa ukubafundisa ngezinqubo zokuphatha ngokuphephile, izinqubo eziphuthumayo kanye nokubaluleka kokuhlolwa ngokomzimba okuvamile ukuze kuqinisekiswe ukutholakala kusenesikhathi kwanoma yiziphi izinkinga zempilo ezihlobene nokuchayeka kwe-barium.
Ama-ejensi alawulayo afana ne-Occupational Safety and Health Administration (OSHA) adlala indima ebalulekile ekumiseni nasekuphoqeleleni izindinganiso zokuphepha ezindaweni zokusebenza eziphethe izinto eziyingozi njenge-barium. Ngakho-ke, kuyadingeka ukuthi izimboni nabaqashi bahlale benolwazi ngale mithetho futhi balwele ukuyithobela.
Kafushane, insimbi ye-barium iyingozi ngempela futhi ingaba yingozi empilweni yomuntu kanye nemvelo uma kungathathwa izinyathelo ezifanele. Izisebenzi eziphatha i-barium nezinhlanganisela zayo kufanele zihlonyiswe ngolwazi oludingekayo, ukuqeqeshwa kanye nemishini yokuzivikela ukuze kuqinisekiswe ukuphepha kwazo. Ukuhambisana ngokuqinile neziqondiso zokuphepha kanye nemithethonqubo yezemvelo kubalulekile ekunciphiseni izingozi ezingase zibe khona ezihlobene nensimbi ye-barium nokugcina indawo yokusebenza ephephile.
