Kev ceev faj rau kev siv cov tub yees thiab kev kho thaum muaj xwm txheej ceev ntawm cov dej xau
1. Cov lus ceeb toom ntawm kev siv cov tub yees
1. Tsis txhob nkag mus rau cov dej vapor uas muaj concentrated heev. Txawm hais tias qee cov tub yees tsis muaj hluav taws kub hnyiab tau nyob rau hauv qhov kub thiab txias, lawv cov khoom sib tov tuaj yeem kub hnyiab tau thiab txawm tawg nyob rau hauv qhov kub siab thiab siab concentrations ntawm huab cua.
2. Kev cia cov tub yees yuav tsum tau khaws cia kom deb ntawm qhov chaw hluav taws kub thiab kub kub ntawm cov hlau.
3. Cov tshuaj toxicity ntawm cov tub yees yog tsawg, tab sis ntau npaum li cas ntawm inhaled refrigerants (piv txwv li: R407C) yuav ua rau cov tshuaj loog, thiab cov concentrations siab heev yuav ua rau lub plawv dhia thiab tuag tam sim ntawd. Yog tias qhov concentration ntawm R407C thiab R134a nyob rau hauv qhov chaw kaw yog siab, nws yuav ua rau asphyxia vim hypoxia.
4. Qhov muag, tes thiab tawv nqaij tiv nrog cov tub yees yuav ua rau frostbite, thov hnav cov hnab looj tes tiv thaiv kab mob thaum xav tau.
5. Cov pa sib xyaw nrog cua yuav tsum tsis txhob siv rau kev ntsuas siab thiab xau.
6. Tsis txhob tso cua sov rau cov khoom ua kua uas muaj cov tub yees. Cua sov thiab decomposition yuav ua rau muaj kuab heev thiab (R407C muaj zog corrosive) (R134a irritating) chav; yog tias overheated, cov kua txais yuav tawg.
7. Tsis txhob ntaus lossis ua phem rau lub raj mis tub yees.
8. Lub raj mis tub yees yuav tsum muab tso rau ntsug.
9. Siv ib lub wrench tsim nyog qhib thiab kaw lub valve ntawm lub raj mis tub yees.
2. Cov dej xau ntawm lub tub yees thiab kev kho mob xwm txheej ceev
Thaum cov refrigerant xau, ntau cov pa luam yeeb tawm ntawm qhov xau, thiab ib puag ncig ib puag ncig muaj cov ntxhiab tsw muaj zog; cov khoom siv thiab cov kav dej ntawm cov xau yog txias thiab khov heev.
1. Kev tiv thaiv, khoom siv tiv thaiv thiab cov txheej txheem xwm txheej ceev rau cov neeg ua haujlwm:
1) Txheeb xyuas thaj chaw ceeb toom raws li thaj chaw cuam tshuam ntawm cov pa roj, thiab tshem tawm cov neeg ua haujlwm tsis cuam tshuam mus rau thaj chaw nyab xeeb los ntawm kev hla cua thiab cua ntsawj ntshab.
2) Rau kev nyab xeeb, kom deb ntawm qhov chaw xau.
3) Nws raug pom zoo tias cov neeg teb xwm txheej ceev yuav hnav lub siab zoo ntawm tus kheej lub tshuab ua pa thiab cov khaub ncaws ua haujlwm. Tsis txhob kov lossis hla dhau qhov nchuav.
4) Txiav tawm qhov dej ntws tawm kom ntau li ntau tau. Txau dej txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau vapor.
5) Nws yog txwv tsis pub cuam tshuam ncaj qha rau cov dej xau los yog cov dej xau.
2. Kev tiv thaiv ib puag ncig:
1) Txiav tawm qhov dej ntws tawm kom ntau li ntau tau. Cov nchuav me me tuaj yeem evaporate yog tias muaj qhov cua txaus. Yog tias qhov nchuav loj heev, ua kom qhov cua hauv cheeb tsam thiab npog nws nrog xuab zeb lossis lwm yam khoom siv uas tsim nyog.
2) Tiv thaiv kom tsis txhob muaj cov kua dej nkag mus rau hauv cov kav dej, cov kav dej, hauv qab daus lossis qhov chaw ua haujlwm, thiab tiv thaiv cov roj los ntawm cov kav dej, qhov cua thiab qhov chaw kaw. Vim nws vapor yuav ua rau suffocation.
3) Cov pa xau tau tso cai tawm mus rau hauv qhov chaw, thiab qhov chaw xau yog khaws cia qhov cua.
4) Yog tias hluav taws tshwm sim, siv cov xov xwm tua hluav taws tua hluav taws. Ntxuav lub tank tub yees nrog dej kom txias; los yog siv lub tshuab tua hluav taws.
3. Kev ntsuas kub ceev
1. Kev nqus pa
Tsawg concentrations ntawm inhalation tuaj yeem ua rau khaus khaus, thiab qhov siab ntawm R407C nyob rau hauv cov huab cua yuav ua rau cov tshuaj loog, nrog rau kev tsis nco qab. Kev nqus pa siab heev yuav ua rau lub plawv dhia tsis zoo thiab tuag sai sai.
Mob lom lom: mob me tshwm sim raws li daim tawv nqaij thiab mucous membrane irritation, rhinitis, laryngitis, thiab bronchitis; pob txha thiab daim tawv nqaij kub hnyiab tuaj yeem tshwm sim. Nyob rau hauv cov xwm txheej hnyav, laryngeal edema, glottis stenosis, pa mucosal cell shedding, airway obstruction thiab suffocation yuav tshwm sim, thiab tej zaum yuav muaj tshuaj lom pulmonary edema thiab daim siab puas.
Txoj kev pov tseg: Yog tias nqus tau pa, tus neeg raug mob yuav tsum tau khaws cia kom deb ntawm qhov chaw siab thiab rov qab los rau hauv qhov chaw sov. Oxygen yog tias tsim nyog. Yog tias ua tsis taus pa los yog qaug zog, ua pa tawm dag zog thiab nrhiav kev kho mob nyob ze.
2. Tiv tauj daim tawv nqaij
Kev sib cuag ntawm daim tawv nqaij nrog cov kua txau yuav ua rau frostbite.
Yog tias frostbite tshwm sim:
1. Soak qhov cuam tshuam rau hauv dej sov uas khaws cia ntawm 38-42 degree kom rov ua kom sov.
2. Tsis txhob rub. Tsis txhob siv dej kub lossis hluav taws kub.
3. Hloov cov khaub ncaws tsis huv.
4. Siv cov hnav khaub ncaws huv, qhuav thiab nrhiav kev kho mob.
Ceeb toom: Tom qab frostbite, khaub ncaws yuav lo rau ntawm daim tawv nqaij.
3. Rau hauv qhov muag
Splashes tuaj yeem ua rau frostbite, clouding ntawm lub lens, perforation ntawm lub cornea, thiab txawm dig muag. Nyob rau hauv rooj plaub ntawm qhov muag tsis pom kev, yaug tam sim ntawd nrog tshuaj ntxuav qhov muag lossis dej, thiab tsis txhob kaw qhov muag tsawg kawg 15 feeb. Tau txais kev kho mob tam sim ntawd.
4. Noj yuam kev
Qhov no tsis zoo li - tab sis thaum nws tshwm sim, nws yuav ua rau frostbite. Tsis txhob yuam ntuav. Yog tias tus neeg raug mob tseem tsis nco qab lawm, lawv yuav tsum ntxuav lawv lub qhov ncauj nrog dej huv thiab ua rau lawv haus dej 200-300ml. Tau txais kev kho mob tam sim ntawd, kev kho mob ntxiv thiab kev pab kho mob. Rau R407C, epinephrine thiab cov tshuaj sympathomimetic zoo sib xws yuav tsum raug zam vim yog mob plawv inotropes.
