Toxicity cov kuab lom ntawm methyl methacrylate yog tsawg. Kev voos ntawm daim tawv nqaij, qhov muag, thiab cov dej qab zib thiab cov luav tau raug pom nyob rau hauv nas thiab luav tau nthuav tawm cov metyl methyl methacrylate. Tshuaj lom neeg yog cov tawv nqaij me me hauv cov tsiaj. Cov nyhuv tau pom feem ntau ntawm cov nquag seem tshaj plaws tom qab kev nqus me ntsis tom qab kev nqus me me methacrylate yog voos ntawm lub qhov ntswg. Qhov cuam tshuam rau lub raum thiab nplooj siab thaum ntau dua ntau dua tau tshaj tawm.
Khaws rau hauv qhov chaw txias, qhuav, zoo ventilated qhov chaw, thiab ua kom qhov kub thiab txias hauv qab 30 ° C.
Khaws rau hauv qhov chaw txias. Khaws lub thawv ntim dav hlau thiab khaws cia rau hauv qhov chaw qhuav, muaj qhov cua.
