| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Toxic if swallowed or inhaled. Harmful if absorbed through skin. corrosive. causes burns to any area of contact. Decomposes to toxic hydrogen sulfide. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin and eyes |
| Eye Contact: | Splashes cause burns to the eyes. |
| Skin Contact: | Causes burning, redness, and pain. May be absorbed through skin and cause hydrogen sulfide poisoning. Harmful in contact with skin. |
| Inhalation: | Inhalation of vapors can lead to hydrogen sulfide poisoning and corrosive ammonia burns. |
| Ingestion: | Ingestion may cause hydrogen sulfide poisoning with nausea, vomiting, headache, convulsions, and death. |

| 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. |
