E behe ka setshelo se tiisitsoeng ka thata 'me se boloke sebakeng se pholileng, se omileng.
1. Sesebelisoa: Sebelisa lijana tsa moea o entsoeng ka lisebelisoa tse lumellanang le litempele, joalo ka khalase kapa polasetiki e itseng. Qoba ho sebelisa lijana tse ka 'nang tsa arabela ka phofo.
2. Tikoloho: Boloka sejana se sebakeng se pholileng le se omileng ho thibela mohopotsi oa mongobo, e ka bakang oxidation kapa lintho tse ling.
3. Mocheso: Boloka sebaka sa polokelo ka mocheso o tsitsitseng ebe o qoba mocheso o feteletseng kapa o bata.
4. Lengolo-tsoibila: Ho ngola ka mokhoa o hlakileng le sejana ka hare le tlhaiso-leseling e loketseng ea polokeho.
5. Lithahasello tsa polokeho
6. Qoba ho hlekefetsa: Etsa bonnete ba hore sebaka sa polokelo se hloekile ebile se se na lithibelo tse ka kenang le phofo.
E tsitsitse mochesong oa kamore moeeng, 'me o qala ho oxitize ho 200 ° C ho theha filimi e teteaneng ea li-oxide.
Qoba li-oxides, Alkalis le Halogens. Niobium e na le khatello e matla ea ho loants'oa ke asiti.
Hangata phofo ea niobium ka kakaretso e nkuoa e le chefo e tlase ebile ha e nkuoe batho ba tlas'a maemo a tloaelehileng a ntseng a sebetsana le maemo a tloaelehileng a ho sebetsana le maemo a tloaelehileng a maemong a tloaelehileng a leholimo. Leha ho le joalo, joaloka mesupo e mengata ea tšepe, e ka ba likotsi tse ling tsa bophelo bo botle haeba litšebeletso tse nepahetseng tsa polokeho li sa lebaleheng. Mona ke mehato ea ho itlhokakala:
1. Ho inhalation: ho inhalation ea mehala e nepahetseng e ka baka ho koata ha pherekano kapa mathata a mang. Tšireletso e nepahetseng ea phepo e nepahetseng e khothalletsoa ha o sebetsana le phofo e ngata ea Niobium kapa libakeng tse lerole.
2. Letlalo ke ho ikopanya
3. Ho kenella: ho kenya mekhoeng ea tšepe ha ho sireletsehe, kahoo ho bohlokoa ho boloka mekhoa e metle ea bohloeki e lokelang ho qoba ho kenella ka phoso.
4. Batho ba bang ba allergic: Le hoja ka seoelo, batho ba bang ba ka ba le lintho tse ling tsa ho nahana ka tšepe ho lekana le niobium.
Ha u tsamaisa phofo ea Niobium, ho bohlokoa ho latela mehato e ikhethang ea ho netefatsa polokeho le ho latela melao. Mona ke meqoso e meng ea bohlokoa eo u ka e nahanang:
1. Ho paka: Sebelisa lisebelisoa tse loketseng tsa ho patelana tse matla le bopaki. Sesebelisoa se lokela ho tiisoa le tse entsoeng ka thepa e sa arabeheng ka niobium.
2. Lengolo-tsoibila: Ho kenyelletsa litaba tsa sephutheloana, ho kenyelletsa lebitso la lik'hemik'hale (niobium phofo) le tlhaiso-leseling efe kapa efe e loketseng ea kotsi. Kenyelletsa litaelo tsa ho sebetsana le tlhaiso-leseling ea maemo a tšohanyetso.
3. Kholiseho ea taolo: Hlahloba le ho latela melao ea lehae, ea machabeng le ea machabeng le ea machabeng le ea machabeng le lipalangoang tsa lipallo tsa tšepe. Sena se ka kenyelletsa litlhoko tse ikhethileng bakeng sa lisebelisoa tse kotsi.
4. Moeli oa boima: Ela hloko moeli oa boima ba thepa ho netefatsa ho kenya ho bolokehileng, ho laolla le ho tsamaisa.
5. Qoba ho tšoaea liphoso: Ho etsa bonnete ba hore phoo phofo ea Niobium e lokolohile ho li-silantants pele ho thepa. Lisebelisoa tse silafetseng li ka baka kotsi nakong ea lipalangoang.
6. Taolo ea mocheso: Haeba ho hlokahala, nahana ka mehato ea taolo ea mocheso ho thibela karabelo e mpe nakong ea lipalangoang.
7. Litokomane: Lokisetsa litokomane tsohle tse hlokahalang tsa ho tsamaisa, ho kenyelletsa le lishiti tsa data tsa polokeho (SDS) le liphatlalatso life kapa life tse hlokahalang.
8 Ba sebetsana le tšireletso: Basebetsi ba terene ba amehang ts'ebetsong ea lipalangoang ka litekanyo tse nepahetseng tsa polokeho le polokeho ea Noobium.
