V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of chromium selenide have not been thoroughly investigated and recorded. Chromium is a confirmed human carcinogen with experimental tumorigenic data. Human poison by ingestion with gastrointestinal effects. (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Selenium compounds are poison by inhalation and intravenous routes. Some selenium compounds are experimental carcinogens. Long-term exposure may be a cause of amyotrophic lateral sclerosis in humans, just as it may cause "blind staggers" in cattle. Elemental selenium has low acute systemic toxicity, but dust or fumes can cause serious irritation of the respiratory tract. Inorganic selenium compounds can cause dermatitis. Garlic odor of breath is a common symptom. Pallor, nervousness, depression, digestive disturbances and death have been reported in cases if chronic exposure (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Acute Effects:
Inhalation: DANGER-POISON. May cause a red, dry throat and garlic odor of breath.
Ingestion: May cause gastrointestinal disorders.
Skin: May cause irritation.
Eye: May cause irritation.
Chronic Effects:
Inhalation: May cause pallor, nervousness, depression, histologic fibrosis of lungs, nasal and/or lung cancer.
Ingestion: No chronic health effects recorded.
Skin: May cause dermatitis.
Eye: No chronic health effects recorded.
Target Organs: May affect the respiratory system.
Routes of Entry: Inhalation, skin, ingestion
Medical Conditions Generally Aggravated By Exposure: Pre-existing respiratory and skin disorders.
Carcinogenicity: NTP: Yes IARC: Yes OSHA: Yes
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 symptoms persists.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persists.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid: None
Incompatibility (Material to Avoid): None recorded.
Hazardous Decomposition Products: Fumes of selenium
Hazardous Polymerization: Will not occur
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified in Section VIII- Special Protection Information. Isolate spill area and provide ventilation. 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.
Waste Disposal Method: Dispose of in accordance with local, state and federal regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH - approved dust, mist, vapor cartridge respirator
Ventilation: Use local exhaust to maintain concentrations at or below the PEL, TLV. General exhaust is recommended
Protective Gloves: Rubber Gloves
Eye Protection: Safety Glasses
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storing: Store in cool, dry area. Store in tightly sealed container. Wash thoroughly after handling.
Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air.
Some of the chemicals listed herein are research or experimental substances which may be toxic, as defined by various governmental regulations. In accordance with Environmental Protection Agency regulations and the Toxic Substance Control Act (TSCA), these materials should only be handled by, or under the direct supervision of, a "technically qualified individual", as defined in 40 CFR 710.29(aa).
The above information is accurate to the best of our knowledge. However, since data, safety standards, and government regulations are subject to change, and the conditions of handling and use or misuse are beyond our control, ESPI makes no warranty, either expressed nor implied, with respect to the completeness or continuing accuracy of the information contained herein, and disclaims all liability for reliance thereon.
