Health.
Exposure effects
Paresthesia have been reported. Headache, irritability, drowsiness and dizziness may occur. There is no evidence of methyl methacrylate-induced teratogenicity in humans but there are conflicting reports in animals.
   Ingestion
Anorexia and nausea has been reported from inhalational exposure. Stomatitis has resulted from contact. Administration to rats by lavage failed to produce gastric lesions.
   Inhalation
Respiratory depression, pulmonary edema, emphysema, and atelectasis have occurred in animals following large doses.
   Skin
Allergic contact dermatitis has been reported. Eczematous reactions of onychial and paronychial tissues have been reported in patients using acrylic plastic nails. Dystrophic nail changes may persist for months. Irreversible loss of the fingernails has occurred.

First aid
 
   Ingestion
Significant systemic toxicity is not expected after acute ingestion; gastrointestinal decontamination is generally not warranted.
   Inhalation
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
   Skin
Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists.
   Eyes
Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.
