2. Impembelelo kokusingqongileyo.
i. iingozi zempilo
Indlela yokuhlasela: ukuphefumla, ukungeniswa.
Iingozi zempilo: Intsimbi yeBarium iphantse ingabi netyhefu. Iityuwa ze-barium ezinyibilikayo ezifana ne-barium chloride, i-nitrate ye-barium, njl. , ukubandakanyeka kwe-myocardial, kunye ne-low blood potassium. Ukukhubazeka kwemisipha yokuphefumla kunye nomonakalo we-myocardial kunokukhokelela ekufeni. Ukuphefumla i-soluble barium compound dust kunokubangela i-acute barium poisoning, ukusebenza kufana netyhefu yomlomo, kodwa indlela yokugaya i-digestive tract ilula. Ukubonakaliswa kwexesha elide kwiikhompawundi ze-barium kunokubangela ukuhluma amathe, ubuthathaka, ukuphefumla kancinci, ukudumba kunye nokukhukuliseka kwe-mucosa yomlomo, i-rhinitis, i-tachycardia, ukwanda koxinzelelo lwegazi kunye nokulahleka kweenwele. Ukuphefumla ixesha elide kwe-insoluble barium compound dust, njenge-barium sulfate, kunokubangela i-barium pneumoconiosis.
ii. ulwazi lwetyhefu kunye nokuziphatha kokusingqongileyo
Iimpawu ezinobungozi: i-chemical reactivity ephantsi, inokutshisa ngokuzenzekelayo emoyeni xa ishushu kwimo enyibilikayo, kodwa uthuli lunokutshisa kwiqondo lokushisa. Inokubangela ukutsha kunye nogqabhuko-dubulo xa isesichengeni sobushushu, ilangatye okanye ukusabela kweekhemikhali. Xa idibana namanzi okanye iasidi, isabela ngobundlobongela kwaye ikhuphe irhasi yehidrojeni ukuze ibangele ukutsha. Ukudibana ne-fluorine, i-chlorine, njl., ukusabela kweekhemikhali ezinobundlobongela kuya kwenzeka. Xa udityaniswe ne-asidi okanye i-asidi ye-dilute, iya kubangela ukutsha kunye nokuqhuma.
Ukutshisa (ukubola) imveliso: i-barium oxide.
3. Iindlela zokubeka iliso likaxakeka kwisiza.
4. Iindlela zokubeka iliso kwiLebhu.
I-Potentiometric titration (GB/T14671-93, umgangatho wamanzi)
Indlela yokufunxa iathom (GB/T15506-95, umgangatho wamanzi)
INcwadana yeNdlela yokufunxa i-Atomic yoVavanyo loMfuniselo kunye noVavanyo lweNkunkuma eZiqina, iGuqulwa siSitishi Jikelele sokuHlolwa kokuSingqongileyo saseTshayina kunye nezinye.
5. Imigangatho yokusingqongileyo.
| Indawo eyayisakuba yiSoviet Union | Ubuninzi obuvumelekileyo bezinto eziyingozi kumoya weworkshop | 0.5mg/m3 |

| iTshayina (iza kwenziwa) | Ubuninzi obuvumelekileyo bezinto ezinobungozi kwimithombo yamanzi okusela | 0.7mg/L |
6. Unyango olungxamisekileyo kunye neendlela zokulahla.
i. impendulo kaxakeka ekuchithekeni
Beka bucala indawo evuzayo kwaye uthintele ukufikelela. Sika umthombo womlilo. Abasebenzi bexesha likaxakeka bayacetyiswa ukuba banxibe iimaski zothuli ezizifunxayo kunye nempahla ekhusela umlilo. Musa ukudibana ngqo nokuchitheka. Ukuchitheka okuncinci: Kuphephe ukuphakamisa uthuli kwaye uqokelele kwizikhongozeli ezomileyo, ezicocekileyo nezigqunyiweyo ezinomhlakulo ococekileyo. Ukutshintshela ukuze kusetyenziswe kwakhona. Ukuchitheka okukhulu: Ukugquma ngeplastiki okanye ngeseyile ukunciphisa ukusasazwa. Sebenzisa izixhobo ezingatshisiyo ukudlulisa kunye nokurisayikilisha.
ii. amanyathelo okukhusela
Ukhuseleko lokuphefumla: Ngokuqhelekileyo akukho khuseleko lukhethekileyo olufunekayo, kodwa kuyacetyiswa ukuba imaski yothuli yokucoca i-self-priming ifakwe kwiimeko ezikhethekileyo.
Ukukhuselwa kwamehlo: Nxiba iiglasi zokhuseleko lwekhemikhali.
Ukhuseleko lomzimba: Nxiba impahla ekhuselayo yeekhemikhali.
Ukhuseleko lwesandla: Nxiba iiglavu zerabha.
Okunye:Ukutshaya kuthintelwe ngokungqongqo kwindawo yomsebenzi. Nikela ingqalelo kucoceko lobuqu.
iii. amanyathelo oncedo lokuqala
Ukuthintana nolusu: Susa impahla engcolileyo kwaye uhlambulule ulusu kakuhle ngesepha namanzi.
UQHAGAMSHELWANO LWEMEHLO: Phakamisa iinkophe uze ugungxule ngamanzi abalekayo okanye i-saline. Funa unyango.
UKUFUTHELA: Susa kwindawo ngokukhawuleza uye kumoya omtsha. Gcina indlela yomoya ivuliwe. Ukuba ukuphefumla kunzima, nika ioksijini. Ukuba ukuphefumla kuyeka, mnike ukuphefumla okufakelweyo ngoko nangoko. Funa unyango.
Ukuginya: Sela amanzi amaninzi ashushu, yenza ukugabha, ukuhlamba isisu nge-2% -5% yesisombululo se-sodium sulfate, kwaye ubangele isifo sohudo. Funa unyango.
Iindlela zokucima umlilo: amanzi, ugwebu, ikharbon diokside, iihalogenated hydrocarbons (ezifana ne-1211 agent agent) kunye nezinye izinto zokucima umlilo. Umgubo wegraphite owomileyo okanye omnye umgubo owomileyo (njengesanti eyomileyo) kufuneka usetyenziswe ukucima umlilo.
