6. Kev nkag mus: Cia nws nyob rau hauv qhov chaw nyab xeeb deb ntawm cov neeg tsis tau tso cai thiab xyuas kom cov ntawv ntaub ntawv muaj kev nyab xeeb (SDS).
Cov lus qhia dav dav
Sab laj tus kws kho mob. Qhia phau ntawv qhia kev nyab xeeb no rau tus kws kho mob ntawm qhov chaw.
Ua pa
Yog nqus tau, txav tus neeg mob mus rau cua tshiab. Yog tias koj tsum tsis ua pa, muab ua pa tawm dag zog. Sab laj tus kws kho mob.
Daim tawv nqaij tiv tauj
Yaug nrog xab npum thiab dej kom ntau. Sab laj tus kws kho mob.
qhov muag hu
Yaug kom huv nrog cov dej kom ntau li 15 feeb thiab sab laj kws kho mob.
Kev noj
Nws yog txwv tsis pub ua kom ntuav. Tsis txhob pub dab tsi los ntawm lub qhov ncauj rau tus neeg tsis nco qab lawm. Yaug koj lub qhov ncauj nrog dej. Sab laj tus kws kho mob.
Zoo li ntau yam tshuaj lom neeg, diisopropyl malonate ua qee yam phom sij. Nov yog qee qhov kev phom sij muaj peev xwm cuam tshuam nrog nws:
1. Flammability: Diisoproyl malonate yog cov nplaim taws thiab yuav tsum tau ceev tseg kom deb ntawm cov nplaim taws, cov txim taws thiab cov khoom cua sov.
2. Kev Noj Qab Haus Huv:
Daim tawv nqaij thiab qhov muag khaus: kev sib chwv nrog tawv nqaij lossis qhov muag yuav ua rau khaus. Cov cuab yeej tiv thaiv tiv thaiv thaum tuav.
Inhalation Kev Nyuaj Siab: Inhalation ntawm Vapor yuav ua rau muaj kev cuam tshuam ua pa. Tsim nyog cua tsim nyog yuav tsum tau tswj xyuas thaum siv cov compound no.
3. Toxicity: Txawm hais tias Diisopropyl malonate tsis tau cais raws li cov tshuaj lom heev, nws tseem yuav tau ua raws li kev saib xyuas. Kev sib tw ntev los yog raug rau cov kev xav zoo yuav ua rau muaj kev noj qab haus huv cuam tshuam.
4. Ib puag ncig kev puas tsuaj: tej zaum yuav muaj kev phom sij rau cov neeg muaj lub neej kom tsim nyog kom muaj pov tseg kom muaj pov tseg kom muaj pov tseg ib puag ncig ib puag ncig.
