| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to eyes, skin, and respiratory tract. Toxic by inhalation and if swallowed. May cause heritable genetic damage, harm to the unborn child, and impair fertility. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin, eyes. |
| Eye Contact: | Causes irritation, redness and pain. |
| Skin Contact: | Causes irritation, redness and pain. May be absorbed through the skin. |
| Inhalation: | Toxic. Causes irritation to the respiratory tract, and in large amounts, poisoning. |
| Ingestion: | Toxic. Ingestion of as little as 1/2 ounce may cause nitrite poisoning including intense cyanosis, nausea, dizziness, vomiting, collapse, coma, and death. |
| Acute Health Effects: | Irritating to eyes, skin, and respiratory tract. Toxic by inhalation and if swallowed. Nitrite poisoning may cause cyanosis, nausea, dizziness, vomiting, collapse, rapid heart beat, irregular breathing, coma, convulsions, circulatory collapse and death. May cause harm to the unborn child. |
| Chronic Health Effects: | May cause heritable genetic damage and impair fertility. |
| NTP: | No |
| IARC: | No |
| OSHA: | No |
| 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 immediately with water. Remove contaminated clothing 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. |
