Cov tshuaj no muaj ntau yam kev siv, suav nrog kev noj rau tib neeg. Tab sis nyob rau hauv nws daim ntawv ntshiab, nws tuaj yeem ua rau xeb, kub hnyiab thiab tuag taus.
Qhov xwm txheej ntawm LyondellBasell complex tau tso tawm kwv yees li 100,000 phaus ntawm acetic acid, ua rau kub hnyiab thiab ua rau muaj teeb meem ua pa rau cov neeg dim.
Acetic acid yog ib yam kua tsis muaj xim, ib yam organic compound uas muaj ntxhiab tsw qab siv rau hauv kev tsim cov xim, cov sealants, thiab cov nplaum. Nws kuj yog cov khoom tseem ceeb ntawm vinegar, txawm hais tias nws qhov concentration tsuas yog li 4–8%.
Raws li cov ntaub ntawv ntawm LyondellBasell lub vev xaib, nws tsim tsawg kawg yog ob hom glacial acetic acid. Cov khoom no tau piav qhia tias yog anhydrous.
Raws li daim ntawv qhia kev nyab xeeb ntawm lub tuam txhab, cov tshuaj no yooj yim hlawv thiab tuaj yeem ua rau muaj cov pa tawg ntawm qhov kub siab tshaj 102 degrees Fahrenheit (39 degrees Celsius).

Tus qauv tsawg kawg nkaus uas tau teeb tsa los ntawm Occupational Safety and Health Administration yog 10 feem ib lab (ppm) rau lub sijhawm yim teev.
Lub Chaw Tswj thiab Tiv Thaiv Kab Mob qhia tias yog tias koj raug tus kab mob, koj yuav tsum tau mus rau qhov chaw muaj huab cua ntshiab tam sim ntawd, tshem tawm tag nrho cov khaub ncaws uas muaj kab mob, thiab ntxuav qhov chaw muaj kab mob nrog dej ntau.
