| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Harmful if swallowed. Aqueous solutions of sodium silicate are strongly alkaline and corrosive to eyes, skin and respiratory tract. May cause harm to the unborn child. |
| Primary Routes of Exposure: | Skin, eyes, Ingestion |
| Eye Contact: | Alkaline dust and aqueous solutions causes burns to the eyes. |
| Skin Contact: | Causes burns of the skin. |
| Inhalation: | (As dust) This alkaline material is corrosive to the nose, mucous membranes and respiratory tract. |
| Ingestion: | Harmful if swallowed. Small amounts exhibit little toxicity. Large amounts may produce caustic burns due to alkalinity. |
| Acute Health Effects: | Dust and aqueous solutions are Irritating to skin, eyes and respiratory tract due to alkalinity. Corrosive to gastrointestinal tract if swallowed. May cause harm to the unborn child. |
| Chronic Health Effects: | Reproductive effector by RTECS criteria. |
| 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. |
