| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Mercury salts are poisonous by ingestion and inhalation of dust. Acute effects include kidney failure. Prolonged exposure may cause heritable genetic damage and impaired fertility. |
| Primary Routes of Exposure: | Ingestion, skin, Inhalation of dust. |
| Eye Contact: | Causes mild to severe irritation of the eyes. May deposit mercury in the lens of the eye. |
| Skin Contact: | Causes mild to severe irritation of the skin. Toxic in contact with skin. |
| Inhalation: | Toxic by inhalation. Dust will cause severe respiratory and gastrointestinal distress, and may damage the central nervous system. |
| Ingestion: | Very toxic if swallowed. Lack of appetite, abdominal cramps, vomiting, kidney failure, paralysis. Mercury binds to thiol groups of protein. |
| Acute Health Effects: | Poison. Stomach upset and pain, mouth pain, vomiting, excessive salivation, urine production stops, urine products appear in the blood, ataxia (difficulty in moving). |
| Chronic Health Effects: | The chronic effects of mercury poisoning include stomatitis, tremors, psychic disturbances, excessive salivation, dermatitis, and pain on chewing. May cause heritable genetic damage and impair fertility. |
| NTP: | No |
| IARC: | Yes |
| 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. |
