IRRITATE THE EYES, RESPIRATORY SYSTEM & CAUSE SKIN RASHES. MAY
AFFECT THE NOSE, LIVER & KIDNEYS. REPEATED/PROLONGED OVEREXPOSURE
MAY CAUSE PERMANENT BRAIN & NERVOUS SY STEM DAMAGE, ALLERGIC SKIN
RASHES, EYE CORROSION & PERMANENT INJURY, CHANGES IN LIVER & KIDNEY
FUNCTION/DAMAGE.
Effects of Overexposure:METHYL METHACRYLATE MONOMER: IRRITATION, RASH,
HEADACHES, NAUSEA, STAGGERING GAIT, CONFUSION, DROWSINESS,
UNCONSCIOUSNESS, BURNS.
