| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to skin, eyes and respiratory tract. Harmful by inhalation, in contact with skin and if swallowed. Possible risk of harm to the unborn child, impaired fertility and irreversible effects. |
| Primary Routes of Exposure: | Ingestion, inhalation, skin and eyes. |
| Eye Contact: | The dust causes slight to mild irritation of the eyes. Symptoms include redness, and pain. |
| Skin Contact: | Harmful in contact with skin. Causes irritation to the skin. |
| Inhalation: | Harmful by inhalation. May be irritating to the nose mucous membranes and respiratory tract. Symptoms include coughing, wheezing and sore throat. |
| Ingestion: | Harmful if swallowed. High doses may cause boron poisoning: convulsions, cyanosis, coma and death. |
| Acute Health Effects: | Irritating to eyes, skin and respiratory tract. High doses may cause convulsions, cyanosis, coma, and death. Possible risk of harm to the unborn child. |
| Chronic Health Effects: | Repeated ingestion of boron compounds may cause dryness of mucous membranes, anorexia, vomiting, mild diarrhea, skin rash, and low blood cell count. Kidney damage may occur. Possible risk of impaired fertility and irreversible effects. |
| 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. |
