numbness, nausea, vomiting and tremors.
Medical Conditions Generally Aggravated by Exposure: None known.
Section 4: First Aid Measures
If swallowed, call a physician or Poison Control Center. Do not induce vomiting. This product contains
aromatic petroleum solvent. Aspiration may be a hazard. Promptly drink a large quantity of milk, egg
white, and gelatin solution, or if these are not available, water. Avoid alcohol.
If inhaled, remove victim to fresh air. If not breathing, administer artificial respiration, preferably by
mouth to mouth. Get medical attention.
If on skin, wash with plenty of soap and water. Get medical attention if irritation persists.
If in eyes, flush eyes with plenty of water. Get medical attention if irritation persists.
