| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to skin and eyes. May form boron oxides on ingestion, large amounts causing boron poisoning resulting in depression of circulation, vomiting, diarrhea, shock, and coma. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin and eyes. |
| Eye Contact: | The liquid causes irritation of the eyes. Symptoms include redness, and pain. |
| Skin Contact: | The liquid causes irritation and dryness of the skin and skin rash. |
| Inhalation: | This high boiling liquid is unlikely to be inhaled |
| Ingestion: | Forms boron oxides. May be toxic by ingestion. High doses may cause boron poisoning: convulsions, cyanosis, coma and death. |
| Acute Health Effects: | Irritating to skin and eyes. Boron oxide hydrolysis products may cause twitching of facial muscles. High doses may cause convulsions, cyanosis, coma, and death. |
| Chronic Health Effects: | Repeated ingestion may cause dryness of mucous membranes, anorexia, vomiting, mild diarrhea, skin rash, and low blood cell count. Kidney damage may occur. |
| 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 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. |
