| SPECIAL FIRE FIGHTING PROCEDURES | |
|
Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution. |
|
| UNUSUAL FIRE AND EXPLOSION HAZARDS | |
|
May be flammable when exposed to flame or by spontaneous chemical reaction. When heated to decomposition, yttrium sulfide may emit highly toxic fumes of sulfur oxides. Many sulfides ignite easily in air at room temperature, others require a higher temperature or the presence of an oxidizer. Upon contact with steam or acids, hydrogen sulfide may be evolved, which can form explosive mixtures with air. May ignite violently and explosively on contact with powerful oxidizing agents. |

SECTION VI - HEALTH HAZARD DATA |
| HEALTH HAZARDS (ACUTE AND CHRONIC) | |
|
To the best of our knowledge the chemical, physical and toxicological properties of yttrium sulfide have not been thoroughly investigated and recorded. Yttrium is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the rare earth elements inlude writhing, ataxia, labored respiration, walking on the toes with arched back and sedation (animals). 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) Sulfides of the heavy metals are generally insoluble and hence have little toxic action except through the liberation of hydrogen sulfide. (Sax, Dangerous Properties of Industrial Materials, eighth edition) INHALATION: Acute: May cause irritation to the upper respiratory system. Chronic: May cause writhing, ataxia, labored respiration, walking on toes with arched back, sedation, pulmonary edema and lung granuloma. INGESTION: Acute: Considered to have low toxicity by ingestion. Chronic: May act as a blood anticoagulant. SKIN: Acute: May cause irritation, sensitivity to heat and skin lesions. Chronic: May cause skin granuloma. EYE: Acute: May cause moderate irritation. Chronic: No chronic health effects recorded. TARGET ORGANS: May affect the blood, lungs and skin. |

No toxicity data recorded. |
|
| SIGNS AND SYMPTOMS OF EXPOSURE | |
|
INHALATION: May cause a red, dry throat and coughing. INGESTION: May affect the coagulation time of the blood. SKIN: May cause redness, burning, itching, heat sensitivity and skin lesions. EYE: May cause redness, burning, itching and watering. |
|
| MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE | |
|
Pre-existing lung 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. EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention. |

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. |
