In the event of contact or inhalation, seek medical advice. Intoxication by inhalation - Take the victim into the fresh air. - Supply oxygen or apply artificial respiration if necessary. - In case of persistent problems: consult a doctor. B1 Skin contact - Remove contaminated clothing. - Immediately wash thoroughly with soap and water. - In case of persistent irritation of the skin, consult a doctor. Eye contact - Wash well-open eyes immediately, abundantly and thoroughly with water (remove contact lenses where possible). - In case of persistent problems, consult a doctor. Intoxication by ingestion - Rinse out the mouth. - Do not induce vomiting. - Consult a doctor. Where necessary, contact theCedre nearest poison control centre (cf. page 4). 8 Methyl Methacrylate Chemical Response Guide 1 ID card Methyl methacrylate Gross formula: C5H8O2 Semi-developed formula: CH2 = C(CH3)COOCH3 Synonyms MMA; Methacrylic acid methyl ester; Methyl alpha-methacrylate; Methyl B2 ester; 2-methyl-2-propenoic acid; Methyl 2-methyl-2-propenoate; Methyl 2-methylpropenoate.
