| Kev piav qhia dav dav |
Octafluorocyclobutane yog cov roj uas tsis muaj xim tsis muaj nplaim taws. Octafluorocyclobutane tuaj yeem tsim kev puas tsuaj los ntawm asphyxiation. Kev kis ntawm lub thawv rau lub sijhawm ntev los yog hluav taws kub tuaj yeem ua rau Octafluorocyclobutane tawg ua rau muaj kev kub ntxhov thiab foob pob hluav taws. Octafluorocyclobutane yog siv los ua lwm yam tshuaj. |
| Reactivity Profile |
Octafluorocyclobutane yog tshuaj inert nyob rau hauv ntau lub sijhawm, tab sis tuaj yeem ua rau muaj zog nrog cov neeg ua haujlwm txo qis xws li cov hlau nquag thiab cov hlau nquag. Lawv raug kev txom nyem oxidation nrog muaj zog oxidizing cov neeg ua haujlwm thiab nyob rau hauv qhov kub thiab txias. |
| Health Hazard |
Vapors tuaj yeem ua rau kiv taub hau lossis asphyxiation yam tsis tau ceeb toom. Vapors los ntawm cov roj liquefied yog thawj zaug hnyav dua li huab cua thiab kis mus rau hauv av. Kev sib cuag nrog cov roj los yog cov roj liquefied tuaj yeem ua rau kub hnyiab, raug mob hnyav thiab / lossis frostbite. Hluav taws yuav ua rau khaus, corrosive thiab/los yog cov pa phem. |
| Hluav Taws Xob |
Qee tus yuav hlawv tab sis tsis muaj qhov kub hnyiab tau yooj yim. Cov thawv ntim khoom tuaj yeem tawg thaum cua sov. Lub tog raj kheej tawg tuaj yeem foob pob hluav taws. |
| Kev ruaj ntseg Profile |
Mdly tshuaj lom los ntawm kev noj thiab nqus pa. Muaj peev xwm ua rau me ntsis kev cuam tshuam nyob rau hauv high concentrations. Tsis muaj tshuaj loog lossis cov teebmeem hauv nruab nrab ntawm lub paj hlwb. Cov roj uas tsis yog nplaim taws. Cov ntaub ntawv hloov pauv tau tshaj tawm. Thaum rhuab mus rau decomposition nws emits hghly toxic fumes ntawm F-. |
| Ntxim yuav nphav raug |
Cov khoom no yog siv los ua ib lub tub yees. |
| Kev pab thawj zaug |
Yog hais tias cov tshuaj no nkag mus rau hauv lub qhov muag, tshem tawm ib qho kev sib cuag lo ntsiab muag ib zaug thiab irrigate tam sim ntawd rau tsawg kawg yog 15 feeb, qee zaus nqa lub hau sab sauv thiab qis dua. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no kis rau ntawm daim tawv nqaij, tshem tawm cov khaub ncaws tsis huv thiab ntxuav tam sim nrog xab npum thiab dej. Nrhiav kev kho mob tam sim ntawd. Yog tias cov tshuaj no tau nqus tau lawm, tshem tawm ntawm qhov raug, pib ua pa cawm siav (siv kev ceev faj thoob ntiaj teb, suav nrog daim npog qhov ncauj resuscitation) yog tias ua pa tau nres thiab CPR yog tias lub plawv nres. Hloov tam sim ntawd mus rau qhov chaw kho mob. Thaum cov tshuaj no tau nqos, tau txais kev kho mob. Muab dej ntau thiab ua kom ntuav. Tsis txhob ua rau tus neeg tsis nco qab ntuav. Kev soj ntsuam kev kho mob raug pom zoo rau 24-48 h tom qab ua pa ntau dhau, vim tias mob ntsws edema yuav qeeb. Raws li kev pabcuam thawj zaug rau pulmonary edema, tus kws kho mob lossis kws kho mob tuaj yeem txiav txim siab siv tshuaj corticosteroid. |
| khaws cia |
Xim Code-Green: Kev khaws cia dav dav tuaj yeem siv.Ua ntej ua haujlwm nrog cov tshuaj no koj yuav tsum tau kawm txog nws txoj kev tuav thiab khaws cia. Khaws rau hauv cov thawv kaw nruj nreem rau hauv qhov chaw txias, qhov cua zoo kom deb ntawm qhov chaw muaj cua sov siab. Tiv thaiv lub tog raj kheej los ntawm kev puas tsuaj rau lub cev. Cov txheej txheem rau kev tuav, siv, thiab khaws cia ntawm lub tog raj kheej yuav tsum ua raws li OSHA 1910.101 thiab 1910.169, ib yam li cov lus pom zoo ntawm Lub Koom Haum Compressed Gas. |
| Kev xa khoom |
UN1976 octafluorocyclobutane, lossis refrigerant gas RC-318, Hazard class: 2.2; Cov ntawv lo: 2.2-Nonflammable compressed gas. Lub tog raj kheej yuav tsum tau thauj mus rau hauv qhov chaw ruaj ntseg, nyob rau hauv lub tsheb uas muaj cua zoo. Tiv thaiv lub tog raj kheej thiab cov ntawv cim los ntawm kev puas tsuaj rau lub cev. Tus tswv ntawm lub tog raj kheej roj compressed yog tib qhov chaw tso cai los ntawm tsoomfwv txoj cai lij choj (49CFR) los thauj thiab rov qab rau lawv. Nws yog kev ua txhaum cai ntawm kev thauj mus los kom rov ua cov roj compressed cylinders yam tsis tau sau ntawv tso cai los ntawm tus tswv. |
| Txoj Kev Purification |
Purify octafluorocyclobutane los ntawm ntxiab-rau-trap distillation, khaws cia qhov nruab nrab. [Danus Ind Eng Chem 47 144 1955, Claasen J Chem Phys 18 543 1950, Beilstein 5 III 8, 5 IV 8.] |
| Kev tsis sib haum xeeb |
Octafluorocyclobutane yog tshuaj inert nyob rau hauv ntau lub sijhawm, tab sis tuaj yeem hnov mob hnyav nrog cov muaj zog txo cov neeg ua haujlwm xws li hydrides thiab cov hlau nquag thiab tshwj xeeb tshaj yog cov hlau nquag. Lawv raug kev txom nyem oxidation nrog muaj zog oxidizing cov neeg ua haujlwm thiab nyob rau hauv qhov kub thiab txias. |
| Pov tseg pov tseg |
Rov qab refillable compressed gas cylinders rau tus neeg muag khoom. Cov thooj voos kheej kheej uas tsis tuaj yeem yuav tsum tau muab pov tseg raws li cov cai hauv zos, xeev thiab tseemfwv qib siab. Cia cov pa roj ntxiv kom maj mam nkag mus rau hauv cov huab cua hauv qhov chaw tsis muaj kev txwv lossis tso pa tawm. Refillabletype cylinders yuav tsum tau xa rov qab mus rau tus neeg muag khoom qub nrog txhua lub kaus mom valve thiab lub qhov hluav taws xob ntsaws ruaj ruaj thiab lub kaus mom tiv thaiv valve hauv qhov chaw. |
