General Advice: Upon exposure, move to fresh air and seek medical assistance. Remove contaminated clothing and rinse skin with water immediately.
Inhalation: Remove person from contaminated area. Seek medical attention if symptoms such as coughing or shortness of breath occur.
Skin Contact: Wash with soap and water for at least 15 minutes. Remove contaminated clothing and shoes.
Eye Contact: Rinse eyes with water for several minutes, holding eyelids open. Seek medical help if irritation persists.
Ingestion: Rinse mouth with water. Do not induce vomiting unless directed by medical personnel. Seek medical attention at once.
