2. Kukanganisa kwezvakatipoteredza.
i. njodzi dzehutano
Nzira yekupinda: inhalation, kupinza.
Njodzi dzehutano: Barium simbi inenge isiri-chepfu. Soluble barium salts yakadai sebarium chloride, barium nitrate, etc. (barium carbonate inosangana negastric acid kuti iite barium chloride, iyo inogona kutorwa kuburikidza nemagetsi ekudya) inogona kuva nechepfu yakakomba mushure mekudya, nezviratidzo zvekugumburwa kwechirwere chekudya, kuparara kwemhasuru kunowedzera. , kubatanidzwa kwemyocardial, uye kuderera kwe potassium muropa. Kufa mitezo yetsandanyama yekufema uye kukuvara kwemyocardial kunogona kutungamirira kurufu. Inhalation ye soluble barium compound dust inogona kukonzera acute barium poisoning, kushanda kwakafanana nemuromo wechepfu, asi maitiro ekugadzirisa matumbo akareruka. Kugara kwenguva refu kune barium compounds kunogona kukonzera mate, kushaya simba, kupera kwekufema, kuzvimba uye kukukurwa kwemukanwa mucosa, rhinitis, tachycardia, kuwedzera kweropa uye kurasikirwa kwebvudzi. Kufema kwenguva refu kweinsoluble barium compound dust, yakadai sebarium sulfate, kunogona kukonzera barium pneumoconiosis.
ii. toxicological ruzivo uye maitiro ezvakatipoteredza
Hazardous maitiro: yakaderera kemikari reactivity, inogona kungoerekana yapisa mumhepo kana ichipisa kusvika kune yakanyungudutswa, asi guruva rinogona kupisa nekupisa kwekamuri. Inogona kukonzera kupisa uye kuputika kana yaiswa pakupisa, murazvo kana kuita kwemakemikari. Kana yasangana nemvura kana asidhi, inoita zvechisimba uye inoburitsa gasi rehydrogen kukonzeresa kupisa. Mukubatana nefluorine, chlorine, nezvimwewo, mhirizhonga yemakemikari ichaitika. Kana yabatwa neasidhi kana dilute asidhi, inokonzeresa kupisa uye kuputika.
Kupisa (kuora) chigadzirwa: barium oxide.
3. Pa-saiti yekutarisisa nzira dzekukurumidzira.
4. Nzira dzekuongorora marabhoritari.
Potentiometric titration (GB/T14671-93, mhando yemvura)
Atomic absorption nzira (GB/T15506-95, mhando yemvura)
Atomic Absorption Method Manual yeKuongorora Ongororo uye Ongororo Yemarara Yakaoma, Yakashandurwa neChina Environmental Monitoring General Station nevamwe.
5. Mitemo yezvakatipoteredza.
| Yaichimbova Soviet Union | Yakanyanya kubvumidzwa kuwanda kwezvinhu zvine njodzi mumhepo yewekishopu | 0.5mg/m3 |

| China (ichagadziriswa) | Kuwanda kunobvumidzwa kwehuwandu hwezvinhu zvine njodzi mumatsime emvura yekunwa | 0.7mg/L |
6. Emergency kurapwa uye nzira dzokurasa.
i. mhinduro yechimbichimbi pakuteuka
Isora nzvimbo inovuza ine utachiona uye rambidza kupinda. Dimbura panobva moto. Vashandi vekukurumidzira vanorairwa kupfeka masiki eguruva ekusefa uye zvipfeko zvinodzivirira moto. Usasangana zvakananga nekuteuka. Kuteuka kudiki: Dzivisa kusimudza huruva uye kuunganidza mumidziyo yakaoma, yakachena, yakavharwa nefoshoro yakachena. Transfer kuti ishandiswezve. Kurasika kwakakura: Fukidza nepepa repurasitiki kana canvas kuderedza kupararira. Shandisa zvisiri-zvinopisa maturusi kutamisa uye kudzokorodza.
ii. matanho ekudzivirira
Dziviriro yekufema: Kazhinji hapana kudzivirirwa kwakakosha kunodiwa, asi zvinokurudzirwa kuti iyo yekusefa guruva mask mask inopfekwa mumamiriro ezvinhu akasarudzika.
Dziviriro yeziso: Pfeka magirazi ekuchengetedza makemikari.
Kudzivirirwa kwemuviri: Pfeka zvipfeko zvinodzivirira zvemakemikari.
Kudzivirirwa nemaoko: Pfeka magirovhosi erabha.
Zvimwe:Kusvuta kunorambidzwa zvachose panzvimbo yebasa. Ngwarira utsanana hwako.
iii. matanho ekutanga ekubatsira
Kubata ganda: Bvisa zvipfeko zvine utachiona uye wogeza ganda zvakanaka nesipo nemvura.
KUSVIRA KWEZISO: Simudza maziso uye geza nemvura inoyerera kana saline. Tsvaka kurapwa.
KUSVIRA: Bvisa panzvimbo nekukurumidza kuenda kumhepo yakachena. Chengetedza nzira yekufema yakavhurika. Kana kufema kwakaoma, ipa oxygen. Kana kufema kwakamira, ipa artificial kufema nekukasika. Tsvaka kurapwa.
Kudya: Inwa mvura yakawanda inodziya, kurutsa, gastric lavage ne2% -5% sodium sulfate solution, uye kuita manyoka. Tsvaka kurapwa.
Nzira dzekudzima moto: mvura, furo, carbon dioxide, halogenated hydrocarbons (senge 1211 extinguishing agent) nezvimwe zvekudzima moto. Dry graphite powder kana imwe hupfu yakaoma (yakadai sejecha rakaoma) inofanira kushandiswa kudzima moto.
