2. Pharmaceuticals:
   • Ua raws li cov kuab tshuaj, stabilizer, thiab excipient nyob rau hauv qhov ncauj, tshuaj pleev ib ce, thiab txhaj tshuaj.
   • Feem ntau siv nyob rau hauv hnoos syrups, ointments, thiab lotions.
3. Tshuaj pleev ib ce thiab kho tus kheej:
   • Siv rau hauv cov khoom tu tawv nqaij, deodorants, tshuaj zawv plaub hau, thiab tshuaj txhuam hniav rau nws cov moisturizing thiab stabilizing zog.
   • Pab txhim khu kev sib kis thiab nqus ntawm cov khoom.
4. Kev Siv Hluav Taws Xob:
   • Siv los ua cov tshuaj tiv thaiv kab mob thiab ua kom txias hauv HVAC cov tshuab thiab cov khoom siv ua zaub mov.
   • Ua hauj lwm raws li hnyav nyob rau hauv cov xim, coatings, thiab adhesives.
5. E-kua:
   • Ib qho tseem ceeb hauv e-kua rau cov luam yeeb hluav taws xob, muab lub vapor du thiab nqa cov tsw qab.

Kev nyab xeeb thiab tuav:

• Cia:Khaws rau hauv qhov chaw txias, qhuav, thiab qhov cua zoo kom deb ntawm tshav ntuj ncaj qha thiab tshav kub.
• Kev tuav:Siv cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), xws li hnab looj tes thiab looj tsom iav, thaum tuav. Tsis txhob ncua ntev ntawm daim tawv nqaij thiab nqus pa ntawm vapors.
• Kev pov tseg:Pov tseg PG raws li cov cai hauv cheeb tsam ib puag ncig.

Ntim:
