| SECTION 3: Hazards Identification | |
|---|---|
| Emergency Overview: | Irritating to eyes, skin an respiratory tract. Harmful by inhalation, in contact with skin and if swallowed. Chromium (III), a possible metabolite, has acted as a tumorigen and mutagen in animal studies. |
| Primary Routes of Exposure: | Ingestion, inhalation of dust |
| Eye Contact: | Causes slight to mild irritation of the eyes |
| Skin Contact: | Causes slight to mild irritation of the skin. Harmful in contact with skin. |
| Inhalation: | Irritating to the nose, mucous membranes and respiratory tract. Harmful through inhalation. |
| Ingestion: | Harmful if swallowed. |
| Acute Health Effects: | Irritating to skin, eyes and respiratory tract. Harmful through inhalation, in contact with skin and if swallowed. |
| Chronic Health Effects: | It is possible that prolonged exposure could result in formation of Chromium (III) salts in the human body. Although less toxic than Chromium (VI), some animal studies show Chromium (III) to act as a mutagen and tumorigen. |
| NTP: | Yes |
| 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. |
