| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Toxic by inhalation, in contact with skin and if swallowed. Causes burns to respiratory system, skin and eyes. Boron poisoning may cause vomiting, bloody diarrhea, coma and death. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin and eyes. |
| Eye Contact: | Causes burns to the eyes. |
| Skin Contact: | Toxic in contact with skin. Causes burns to the skin. |
| Inhalation: | Toxic by inhalation. Inhalation of dust causes caustic burns to nose, mucous membranes, and respiratory tract. |
| Ingestion: | Toxic if swallowed. High doses may cause vomiting, bloody diarrhea, twitching of facial muscles, convulsions, cyanosis, coma and death. |
| Acute Health Effects: | Toxic by inhalation, in contact with skin and if swallowed. Causes burns to skin, eyes and respiratory tract. 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. |
