4. FIRST AID MEASURES
Inhalation: Remove victim to fresh air and provide oxygen if breathing is difficult. Give artificial respiration if not
breathing. Get medical attention.
Skin contact: In case of contact with hot product, immediately flood the affected area with cold water. Wipe
excess material from exposed area. Flush exposed skin with water and follow by washing with soap if available.
Carefully remove clothing; if clothing is stuck to a burn area do not pull it off, but cut around it. Cover burn area do
not pull it off, but cut around it. Transport to nearest medical facility for additional treatment.
Eye contact: Flush eye with water. Rest eyes for 30 minutes. If symptoms persist, consult a physician.
Ingestion: Do not induce vomiting. Have victim rinse out mouth with water, then drink sips of water to remove
taste from mouth. In general, no treatment is necessary unless large quantities are ingested. However, get
medical advice. If vomiting occurs spontaneously, keep head below hips to prevent aspiration.

Skin: Remove contaminated clothing. Flush skin with water, then wash affected areas with soap and water. If
irritation develops, seek medical attention. Wash or dispose of clothing before reuse.
Eye: Flush eyes with water for 15 minutes. Remove contact lenses prior to water flush if possible. Seek
immediate medical attention.
Respiratory: Remove patient to fresh air. If patient is having difficulty breathing, seek immediate medical
attention. If not breathing, clear airway and start mouth-to-mouth artificial respiration (or use bag-mask
respirator). Seek immediate medical attention.

Section 4 FIRST-AID MEASURES
Skin: Remove contaminated clothing. Flush skin with water, then wash affected areas with soap and water. If
irritation develops, seek medical attention. Wash or dispose of clothing before reuse.
Eye: Flush eyes with water for 15 minutes. Remove contact lenses prior to water flush if possible. Seek
immediate medical attention.
Respiratory: Remove patient to fresh air. If patient is having difficulty breathing, seek immediate medical
attention. If not breathing, clear airway and start mouth-to-mouth artificial respiration (or use bag-mask
respirator). Seek immediate medical attention.
Ingestion: Give patient water to dilute material in stomach. DO NOT induce vomiting. Seek immediate medical
attention. If vomiting occurs naturally, have person lean forward to reduce risk of aspiration. DO NOT give
anything by mouth to an unconscious person.
Section 5 FIRE-FIGHTING MEASURES
Suitable Extinguishing Media: In case of fire, use dry chemical or CO2. Water spray may cause frothing.
