|---|---|
| Emergency Overview: | May cause sensitization by inhalation and skin contact. May be irritating to skin, eyes and respiratory tract. Limited evidence of a carcinogenic effect. Possible risk of irreversible effects |
| Primary Routes of Exposure: | Ingestion, inhalation, skin contact |
| Eye Contact: | May cause mild to moderate irritation of the eyes. |
| Skin Contact: | May cause irritation of the skin. May cause sensitization in contact with skin. |
| Inhalation: | May be irritating to the nose, mucous membranes and respiratory tract. May cause sensitization by inhalation. |
| Ingestion: | No information on the physiological effects of ingestion. May be harmful if swallowed. |
| Acute Health Effects: | May cause sensitization by inhalation and skin contact. May be irritating to skin, eyes and respiratory tract |

| SECTION 4: First Aid Measures | |
|---|---|
| Eye Exposure: | Immediately flush the eyes with copious amounts of water for at least 10-15 minutes. A victim may need assistance in keeping their eye lids open. Get immediate medical attention. |
| Skin Exposure: | Wash the affected area with water. Remove contaminated clothes if necessary. Seek medical assistance if irritation persists. |
| Inhalation: | Remove the victim to fresh air. Closely monitor the victim for signs of respiratory problems, such as difficulty in breathing, coughing, wheezing, or pain. In such cases seek immediate medical assistance. |
| Ingestion: | Seek medical attention immediately. Keep the victim calm. Give the victim water (only if conscious). Induce vomiting only if directed by medical personnel. |
