Tsis txhob siv lub tua hluav taws tso rau hauv cov hluav taws, vim cov hluav taws tua hluav taws yuav ua rau mob raug mob, thiab qhov tshwm sim yog qhov loj heev.
Cov hluav taws tua hluav taws ua rau muaj kev puas ntsoog txawm tias tib neeg siv khaub ncaws hnav. Lub tshuab tua hmoov qhuav muaj 50% phosphoric acid two hydrogen ammonium thiab 25% ammonium sulfate, uas muaj zog corrosiveness. Ib rooj plaub qhia tau tias hluav taws kub xav tias yuav raug cawm los ntawm lub tua hluav taws, tab sis vim yog qhov tsis paub txog lub tua hluav taws, cov txuag tau raug tua nrog lub tshuab tua hluav taws qhuav. Txawm hais tias qhov hluav taws kub tua tau los ntawm cov neeg ua haujlwm hlawv, nws tseem ua rau kev puas tsuaj.
Ntxiv nrog rau cov tua hluav taws tua hluav taws , cov pa roj carbon dioxide extinguishers kuj muaj ntau, siv hom tua hluav taws tua hluav taws xob yuav tsum tsis txhob raug rau cov tawv nqaij, vim tias qhov kub hauv -78 degrees, qhov kub cov khoom kub. Kuj muaj hluav taws xob tua hluav taws, tab sis hom tua hluav taws no tsis tuaj yeem siv rau xov hluav taws, nws yuav ua hluav taws xob.
Cov tua hluav taws tsis tuaj yeem txau tau. Cov kws txawj ntse xav tias:
(1) thaum ib tug neeg hnav khaub ncaws ntau, qhov hluav taws kub yuav tsis hlawv daim tawv nqaij, thiab lub tsho tiv no yuav tsum tau muab tshem tawm sai sai. Cov khaub ncaws khawm muaj ob txhais tes, kom cov khaub ncaws thiaj tawm tau, thiab cov nyees khawm tsis tuaj yeem raug tshem tawm ntawm ib qho, raws li lub sijhawm mus, vim tias lub sijhawm lig dhau lawm. Yog tias koj hnav lub tsho zipper, koj yuav tsum rub tus zip sai sai thiab hle koj cov khaub ncaws.
(2) Yog hais tias ib tug neeg hnav ib lub tsho, nws yuav hlawv yog tias nws nyob hauv hluav taws. Thaum cov khaub ncaws ntawm lub hauv siab nyob hauv hluav taws, lawv yuav tsum nce hauv av sai; Thaum cov khaub ncaws rov qab nyob rau hauv hluav taws, lawv yuav tsum pw hauv av, thiab thaum twg tag nrho cov khaub ncaws nyob rau hauv hluav taws, lawv yuav tsum rov qab rau hauv av, siv lub cev kom hla lub pa thiab npog lub nplaim taws, tab sis qhov ceev ntawm dov rau hauv av yog tsis ceev ceev, lwm yam qhov hluav taws kub tsis tau yooj yim nias tawm.
(3) nyob hauv tsev, siv cov txaj txaj, pam vov los yog hnab ntawv thiab lwm yam tua cov hluav taws, cov nyhuv yog zoo thiab raws sij hawm, tsuav nws rub rov qab los npog lub cev, ces maj mam nce hauv av, cov nplaim taws yuav raug rho tawm tam sim; yog tias muaj dej nyob ze ntawm cov dej, dej tau tuaj yeem nchuav.
(4) hauv tshav puam, yog tias muaj dej ntws thiab pas dej nyob ze cheeb tsam ze, nws tuaj yeem dhia mus rau hauv dej ntiav; tab sis yog lub cev tau raug kub hnyiab lawm thiab cov tawv nqaij tau raug kub hnyiab, nws tsis tsim dhia mus rau hauv dej los yog tsuag ncaj qha mus rau hauv lub cev nrog lub tua hluav taws, vim nws yooj yim rau kis mob hlav nrog cov kab mob.
