Calcium carbide yog cov khoom tsis muaj nplaim taws, tab sis acetylene tso tawm thaum nws decomposition yog tawg thiab ua pa. Nws yog cov nplaim taws heev txawm tias nrog lub sij hawm luv luv sib chwv nrog huab cua thiab muaj peev xwm ntawm kev sib xyaw ua ke txawm nyob hauv nws daim ntawv ntshiab. Nws kuj tseem ua kom yooj yim dua nrog tooj liab, nyiaj, thiab zoo Mercury ua tsis ruaj khov, foob pob ua acetylenides tsis ruaj khov, tawg tau acetylenides. Vim yog hydrogen phosphide nws muaj, nws muaj cov txiaj ntsig zoo nkauj.
Tus reagent yuav tsum tsis txhob tua neeg nrog dej! Yog tias kua tau nkag rau hauv cov thawv nrog cov tshuaj, cov tawg yog ua tau. Hmoov dej qhuav tua hluav taws, qhuav xuab zeb, carbon dioxide thiab Asbestos daim ntaub yuav tsum tau siv rau extinguishing.
Acetylene yog sib zog ntau dua huab cua, yog li nws tuaj yeem khaws cov ntsiab lus siab tshaj plaws ntawm cov pa tsis zoo.
