| Inhalation. | Tshem tawm ntawm scene mus rau huab cua ntshiab. Kom sov thiab nrhiav kev kho mob. | |||||||
| Kev noj haus. | Yaug lub qhov ncauj, muab mis nyuj lossis qe qe thiab nrhiav kev kho mob. | |||||||
| combusction thiab tawg txaus ntshai | Cov yam ntxwv muaj kev phom sij. | Nws tsis hlawv nws tus kheej, tab sis emits kom muaj kuab lom thaum raug rau kub. | ||||||
| Tsim kom muaj kev phom sij tua hluav taws. | Tsis muaj ntaub ntawv muaj | |||||||
| Kev phom sij cov khoom lag luam. | Hydrogen chloride. | |||||||
| Tua hluav taws kom txav. | Ua npuas ncauj, carbon dioxide, qhuav hmoov, xuab zeb thiab av. | |||||||
| Kua Nplaim | Cais tawm cov xau xau thaj chaw tsis huv thiab kev txwv tsis pub nkag. Nws raug nquahu tias cov neeg ua haujlwm thaum muaj xwm ceev hnav lub ntsej muag plua plav (tag nrho cov ntsej muag ntsej muag) thiab acid thiab alkali tiv thaiv tag nrho. Zam kev ua kom muaj plua plav, cheb tsev kom zoo zoo, muab tso rau hauv hnab thiab hloov mus rau qhov chaw nyab xeeb. Yog tias muaj qhov dej xau ntau, npog nws nrog daim ntawv yas lossis cov canvas. Sau thiab rov qab siv dua lossis thauj mus rau qhov chaw pov tseg pov tseg rau kev pov tseg. | |||||||
| Chaw Cia Thiab Tsheb Thauj Mus Los | ①PRECAED RAU KEV UA HAUJ LWM: Kaw ua haujlwm, tso pa hauv zos. Cov neeg ua haujlwm yuav tsum raug cob qhia tshwj xeeb thiab nruj me ntsis ua raws cov txheej txheem ua haujlwm. Nws raug nquahu kom cov neeg ua haujlwm hnav lub ntsej muag plua plav tsis huv, roj hmab kev tiv thaiv kev nyab xeeb, roj hmab acid thiab alkali resistant hnab looj tes. Zam kev plua plav. Zam kev sib cuag nrog alkalis. Thaum kov, thauj khoom thiab tsis txhob maj mam tiv thaiv kev puas tsuaj rau ntim thiab ntim. Hauv cov khoom siv thaum muaj xwm ceev los daws cov tod. Cov thawv ntim tau tuaj yeem tuav cov ntaub ntawv tsis zoo. ②storage ceev faj: Khaws rau hauv qhov chaw txias, qhuav, zoo-ventilated tsev rau khoom. Cia li deb ntawm hluav taws thiab qhov chaw kub. Ntim yuav tsum tau muab ntim, tsis txhob ntub. Yuav tsum tau muab cia cais tawm ntawm Alkalis, thiab lwm yam, tsis txhob muab kev cia. Thaj chaw cia yuav tsum tau nruab nrog cov ntaub ntawv tsim nyog los muaj cov to. ③transport kev ceev faj: Cov pob yuav tsum ua kom tiav thaum pib thauj thauj kev thauj mus los, thiab cov chaw thau khoom yuav tsum ruaj khov. Thaum lub sijhawm thauj mus los, paub tseeb tias lub thawv ntim tsis xau, vau, poob lossis raug puas. Nruj me ntsis txwv kev sib xyaw nrog cov tshuaj alkali thiab cov khoom noj tau zoo. Cov tsheb thauj mus los hauv tsheb yuav tsum tau nruab nrog cov khoom siv thaum muaj xwm ceev. Thaum lub sijhawm thauj mus los, nws yuav tsum tau tiv thaiv los ntawm kev kis tau los ntawm kev kis tau lub hnub ci, nag thiab kub. | |||||||
