2. Umthelela emvelweni.

Mina. Izingozi Zezempilo

Indlela yokuhlasela: ukuphefumula, ukumunca.
Izingozi Zezempilo: I-Barium Metal cishe ayinobuthi. I-Soluble Barium usawoti anjengeBarium Chloride, i-Barium Nitrate, njll. Ukulimala kwemisipha yokuphefumula kanye nomonakalo we-myocardial kungaholela ekufeni. I-inhalation of soluble barium uthuli lungadala ubuthi be-barium, ukusebenza kufana nobuthi bomlomo, kepha ukusabela kweThathi lokugaya ukudla kukhanya. Ukuchayeka isikhathi eside kuma-barium amakhompiyutha kungadala ukugcwala, ubuthakathaka, ukufushane, ukuvuvukala kanye nokuguguleka kwe-mucosa yomlomo, i-rhinitis, i-tachycardia, ukukhuphuka kwengcindezi yegazi nokulahleka kwegazi. Ukuphefumula kwesikhathi eside kothuli oluhlanganisiwe lwe-barium ye-insoluble, njenge-barium sulfate, kungadala ama-barium pneumononies.

II. Imininingwane yobuthi kanye nokuziphatha kwemvelo

Izici ezinobungozi: Ukuvuselelwa kwamakhemikhali okuphansi, kungaziqhenya ngokuzenzakalela emoyeni lapho kufuthelwa isimo esincibilikisiwe, kepha uthuli lungashisa emazingeni okushisa asekamelweni. Kungadala ukuhlanganiswa nokuqhuma lapho kuvezwa ukushisa, ilangabi noma ukusabela kwamakhemikhali. Ngokuxhumana namanzi noma i-acid, iphendula ngobudlova bese ikhipha igesi ye-hydrogen ukwenza ukuhlanganiswa. Ngokuxhumana ne-fluorine, chlorine, njll, kuzokwenzeka ukusabela kwamakhemikhali. Lapho uthintwa nge-acid noma i-diliful acid, kuzodala ukuhlanganiswa nokuqhuma.
Umkhiqizo wokuhlanganisa (ukubola): IBarium Oxide.

I-6. Ukwelashwa okuphuthumayo kanye nezindlela zokulahla.

Mina. Ukuphendula okuphuthumayo kokuchitheka

Hlukanisa indawo evuza indawo engcolisiwe bese ukhawulela ukufinyelela. Nginqume umthombo womlilo. Abasebenzi bezimo eziphuthumayo bayalwa ukuba bagqoke imaski yothuli yokuzijabulisa nokuzivikela komlilo. Musa ukuxhumana ngqo nokuchitheka. Ukuchitheka okuncane: Gwema ukukhulisa uthuli bese uqoqa ezitsheni ezomile, ezihlanzekile, ezimboziwe ngefosholo elihlanzekile. Dlulisela ukuphinda usebenzise kabusha. Ukuchitheka okukhulu: ikhava nge-petches yepulasitiki noma i-canvas ukunciphisa ukuhlakazwa. Sebenzisa amathuluzi angakhangi ukudlulisa nokuphinda usebenzise kabusha.

II. Izindlela Zokuvikela

Ukuvikelwa kokuphefumula: Ngokuvamile akukho ukuvikelwa okukhethekile okudingekayo, kepha kunconywa ukuthi imaski yothuli lokuzihlunga ukuze igqoke ezimweni ezikhethekile.
Ukuvikelwa kwamehlo: Gqoka izibuko zokuphepha zamakhemikhali.
Ukuvikelwa ngokomzimba: Gqoka izingubo zokuvikela amakhemikhali.
Ukuvikelwa Kwezandla: Gqoka amagilavu ​​enjoloba.
Okunye: Ukubhema akuvunyelwe ngokuphelele endaweni yomsebenzi. Nakisisa inhlanzeko yomuntu siqu.

III. Izindlela Zomsizi Wokuqala

Ukuxhumana kwesikhumba: Susa izingubo ezingcolisiwe bese ugeza isikhumba kahle ngensipho nangamanzi.
Ukuthintwa ngamehlo Funa ukunakekelwa kwezokwelashwa.
Ukuphefumula: Susa endaweni yesehlakalo ngokushesha emoyeni omusha. Gcina i-Airway ivulekile. Uma ukuphefumula kunzima, nikeza umoya-mpilo. Uma ukuphefumula kumisa, nikeza ukuphefumula kokufakelwa ngokushesha. Funa ukunakekelwa kwezokwelashwa.
Ukungenisa: Phuza amanzi amaningi afudumele, unxenxa ukugabha, ukufutheka kwesisu nge-2% -5% sodium sulfate solution, futhi unxenxa uhudo. Funa ukunakekelwa kwezokwelashwa.

Izindlela zokucisha umlilo I-graphite ye-graphite eyomile noma enye i-powder eyomile (efana nesihlabathi esomile) kumele isetshenziselwe ukucisha umlilo.
