| kev phom sij | Cov khoom no yog tshuaj lom. Nyob rau hauv kev sib cuag nrog dej, nws muaj peev xwm tsim hydrogen chloride, uas muaj ib tug irritating nyhuv ntawm daim tawv nqaij thiab mucous daim nyias nyias. | |||||||
| Flammability txaus ntshai | Tsis muaj ntaub ntawv | |||||||
| Kev pab thawj zaug Kev ntsuas | Tiv tauj daim tawv nqaij. | Tshem cov khaub ncaws tsis huv thiab yaug kom huv si nrog xab npum thiab dej. | ||||||
| Qhov muag sib cuag. | Tam sim ntawd qhib daim tawv muag sab sauv thiab sab qis thiab yaug nrog dej ntws rau 15 feeb. Nrhiav kev kho mob. | |||||||
| Inhalation. | Tshem tawm ntawm qhov chaw mus rau huab cua ntshiab. Ua kom sov thiab nrhiav kev kho mob. | |||||||
| Noj. | Yaug lub qhov ncauj, muab mis nyuj los yog qe dawb thiab nrhiav kev kho mob. | |||||||
| combustion thiab tawg phom sij | Cov yam ntxwv txaus ntshai. | Nws tsis hlawv nws tus kheej, tab sis emits cov pa phem thaum raug tshav kub. | ||||||
| Building Code Fire Hazard Classification. | Tsis muaj ntaub ntawv | |||||||
| Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob. | Hydrogen chloride. | |||||||
| Txoj kev tua hluav taws. | Ua npuas ncauj, carbon dioxide, hmoov qhuav, xuab zeb thiab av. | |||||||
| pov tseg | Cais tawm thaj chaw uas muaj paug thiab txwv kev nkag mus. Nws raug pom zoo tias cov neeg ua haujlwm xwm txheej ceev yuav hnav lub ntsej muag plua plav (dawb lub ntsej muag lub ntsej muag) thiab cov kua qaub thiab alkali resistant zuag qhia tag nrho. Tsis txhob tsa cov plua plav, cheb kom zoo, muab tso rau hauv lub hnab thiab hloov mus rau qhov chaw nyab xeeb. Yog tias muaj ntau qhov dej ntws tawm, npog nws nrog cov ntawv yas lossis canvas. Sau thiab rov ua dua lossis thauj mus rau qhov chaw kho cov khib nyiab pov tseg. | |||||||
| khaws cia thiab ceev faj txog kev thauj mus los | ① Kev ceev faj rau kev ua haujlwm: kaw kev ua haujlwm, tso pa hauv zos. Cov neeg ua haujlwm yuav tsum tau cob qhia tshwj xeeb thiab ua raws li cov txheej txheem ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav nws tus kheej-absorbing filtering plua plav qhov ncauj qhov ntswg, tshuaj tiv thaiv tsom iav, roj hmab acid thiab alkali resistant khaub ncaws, roj hmab acid thiab alkali resistant hnab looj tes. Tsis txhob tsim cov hmoov av. Tsis txhob sib cuag nrog alkalis. Thaum tuav, thauj khoom thiab tshem tawm maj mam txhawm rau tiv thaiv kev puas tsuaj rau cov ntim thiab ntim. Nruab nrog cov khoom siv thaum muaj xwm txheej ceev los daws cov dej xau. Cov thawv ntim khoob yuav khaws cov khoom tsim kev puas tsuaj. ② Cia ceev faj: Khaws rau hauv qhov chaw txias, qhuav, zoo-ventilated warehouse. Khaws kom deb ntawm qhov hluav taws kub thiab qhov cua sov. Ntim yuav tsum tau kaw, tsis txhob ntub. Yuav tsum tau muab cais los ntawm alkalis, thiab lwm yam, tsis txhob sib tov cia. Qhov chaw cia khoom yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog kom muaj qhov to. ③ Kev ceev faj txog kev thauj mus los: lub pob yuav tsum ua kom tiav thaum pib tsheb thauj mus los, thiab kev thauj khoom yuav tsum ruaj khov. Thaum lub sij hawm kev thauj mus los, xyuas kom lub thawv tsis xau, tawg, poob los yog puas. nruj me ntsis txwv tsis pub sib tov nrog alkali thiab edible tshuaj. Cov tsheb thauj mus los yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev. Thaum lub sij hawm kev thauj mus los, nws yuav tsum tau tiv thaiv los ntawm raug tshav ntuj, los nag thiab kub. | |||||||
