Emergency overview: This material is harmful byu inhalation, in contact with skin and if ingested. Signal Word Harmful! Physical Health Hazards: Harmful by inhalation, in contact with the skin and if swallowed. Target organ(s): Liver Personal protection: Wear approved protective clothing when working with this material in order to avoid any contact with material at all. Long sleeves and/or lab coat are recommended to protect against skin contact. Approved chemical goggles are recommended to protect against eye contact. Physical state: Solid powder or chunks Color: Bright yellow powder and chunks Odor: None Odor threshold: No data available Potential Health Effects: Routes of exposure Eye contact, ingestion, skin contact Signs and Symptoms of Acute Exposure: Eye and skin irritation; ingestion, not known. Chronic Health Effects Summary: Not known. Conditions Aggravated by Exposure: No known conditions are aggravated by this material.
Take proper precautions to ensure your own health and safety before attempting to rescue and providing first aid. For specific information refer to the Emergency Overview in Section of this MSDS. Inhalation: If symptoms are experienced, move victim to fresh air, and obtain medical attention. Eye Contact: Wash eyes with copious amounts low-pressure water, removing contact lenses if possible. Then seek medical advice from a qualified physician. Skin Contact: Remove contaminated clothing, then rinse skin thorough with soap and water to remove all traces of the substance. Ingestion: Adverse health effects due to ingestion to be expected. Wash out mouth with water but never give liquids to an unconscious person. Call a physician at once and seek other medical attention.
NFPA Rating: Not known Flammability classification: Not known. Flash Point/Method: Not applicable Auto-Ignition Temperature: Not known Flammable Limits: Lower: Not applicable Upper: Not applicable Hazardous Combustion Products: Selenium and selenium oxides. One can also expect the emission of other toxic fumes under fire conditions. Special Conditions to Avoid: Strong oxidizing agents, moisture, oxygen/air, strong acids Extinguishing Media: Fires: Use dry chemicals, CO2, water spray, or appropriate foam. Fire Fighting Instructions: Protective Equipment/Clothing: Wear a NIOSH approved positive pressure self-contained breathing apparatus and firefighter turnout gear. Wear long sleeves and chemical goggles for eye protection. Instructions: Use flooding quantities of water until well after fire is out. If the product now wet with water starts to migrate to other areas or even to the outside environment, dike it at once to prevent that from happening.
Release response: Wear NIOSH approved respirator, chemical safety goggles, rubber boots, and heavy rubber gloves. Sweep up wet product, place in a bag and hold for waste disposal. If product is tending to flow away from fire or spill area, try to dike the material to keep in one place. If a broom is used, remember that the broom, when dried out, will contain powder of the product and if the broom is put into continued use without proper cleaning, then a hazardous dust cloud could be created. Ventilate area and wash spill site after pick up is complete. Reportable Quantities: See Section 15: Regulatory information.
Handling: Use full protective gear as described above. Storage: Keep container dry. Store away from excessive heat and away from strong oxidizing agents and moisture. Keep container closed to prevent contamination.
Engineering Controls: If user operations generate dust or fumes, ventilate area to prevent accumulation. Personal Protection: Inhalation: Use appropriate respiratory protection at all times. If product is to be used as part of a vacuum deposition process, we would recommend that all vacuum pumps be vented to the outdoors, in order to avoid any possible release of Se compounds into the laboratory environment. Skin: Protective clothing such as long sleeves or a lab coat should always be worn. When handling heated materials, also be sure to use heat-resistant gloves, boots and chemical goggles. Eye: Always use chemical goggles, even for work with small quantities, such as the loading of a tungsten basket or boat prior to making a deposition of the material.
