| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Harmful by inhalation. May be irritating to skin, eyes and respiratory tract. Boron affects the central nervous system. Boron poisoning causes depression of circulation, vomiting, diarrhea, shock and coma. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin and eyes. |
| Eye Contact: | May cause slight to mild irritation of the eyes. |
| Skin Contact: | May cause irritation and dryness of the skin and skin rash. |
| Inhalation: | Harmful by inhalation. May be irritating to nose, mucous membranes, and respiratory tract. |
| Ingestion: | May be toxic by ingestion. High doses may cause boron poisoning: convulsions, cyanosis, coma and death. |
| Acute Health Effects: | Harmful by inhalation. May be irritating to skin, eyes and respiratory tract. Redness and pain in eyes, sore throat and twitching of facial muscles may occur. |
| Chronic Health Effects: | Repeated ingestion of some boron compounds 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. |
