SECTION VI - HEALTH HAZARD DATA |
| HEALTH HAZARDS (ACUTE AND CHRONIC) | |
|
To the best of our knowledge the chemical, physical and toxicological properties of gadolinium metal have not been thoroughly investigated and recorded. Gadolinium is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the rare earth elements include writhing, ataxia, labored respiration, walking on the toes with arched back and sedation. The rare earth elements exhibit low toxicity by ingestion exposure. However, the intraperitoneal route is highly toxic while the subcutaneous route is poison to moderately toxic. The production of skin and lung granulomas after exposure to them requires extensive protection to prevent such exposure. (Sax, Dangerous Properties of Industrial Materials, eighth edition) INHALATION: Acute: May cause irritation to the respiratory tract and mucous membrane. Dusts may cause asthma attacks and lung damage such as lung granulomas. Large doses may cause writhing, loss of muscle coordination, labored respiration, sedation, hypotension and cardiovascular collapse. Chronic: Prolonged or repeated inhalation may cause writhing, loss of muscle coordination, labored respiration, sedation, hypotension and cardiovascular collapse. INGESTION: Acute: May cause gastrointestinal irritation. Chronic: May affect the coagulation rate of the blood. SKIN: Acute: May cause irritation, rashes and skin granulomas. Chronic: May cause dermatitis, sensitivity to heat, itching and skin lesions. EYE: Acute: May cause irritation. Chronic: No chronic health effects recorded. TARGET ORGANS: May affect the respiratory system, blood and skin. . |

|
| SIGNS AND SYMPTOMS OF EXPOSURE | |
|
INHALATION: May cause writhing, ataxia, labored respiration, walking on the toes with arched back and sedation. INGESTION: May cause nausea, vomiting, diarrhea, abdominal burning and cramp-like pain. SKIN: May cause redness, itching and burning. EYE: May cause redness, itching, burning and watering. . |
|
| MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE | |
|
Pre-existing respiratory disorders. . |
|
| EMERGENCY AND FIRST AID PROCEDURES | |
|
INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention. INGESTION: Give 1-2 glasses of milk or water and induce vomiting; seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person. SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention if irritation persists. EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if irritation persists. . |

SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE |
| STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED | |
|
Wear appropriate respiratory and protective equipment specified in section VIII-control measures. Isolate spill area, provide ventilation and extinguish sources of ignition. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust. Use non-sparking tools. . |
|
| WASTE DISPOSAL METHOD | |
|
Dispose of in accordance with local, state and federal regulations. . |
