IV FIRE AND EXPLOSION HAZARDS DATA
Flash Point: N/A Autoignition Temperature: N/A
Flammable Limits: Lower: N/A Upper: N/A
Extinguishing Media: Dry Chemical, Class D Extinguisher. DO NOT USE WATER.
Special Fire Fighting Procedures: Wear NIOSH/MSHA approved self-contained breathing apparatus and full protective clothing.
Unusual Fire & Explosion Hazard: Dysprosium will burn under fire conditions. May react with water liberating flammable, explosive hydrogen gas. Thin foils may ignite by spark or static electricity. Like most dry chemicals, in a powder or dust form, this product (when mixed with air in critical proportions and in the presence of an ignition source) may present an explosion hazard.
V HEALTH HAZARD INFORMATION
Effects of Exposure:
Inhalation: May cause upper respiratory tract irritation.
Ingestion: Evidence suggests low toxicity potential due to poor absorption by the oral route.
Skin: Evidence suggests low toxicity potential due to poor skin absorption. May cause irritation.
Eye: May cause irritation.
Other: Has anticoagulant effect when given intravenously.
Chronic Effects: No data found.
Carcinogenicity: NTP: No IARC: No ACGIH: No OSHA: No
Medical Conditions Possibly Aggravated by Overexposure: No data found.
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove from area of exposure. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. GET IMMEDIATE MEDICAL ATTENTION.
INGESTION: If swallowed and victim is fully conscious, induce vomiting immediately by giving two glasses of water and sticking finger down throat. GET IMMEDIATE MEDICAL ATTENTION.
SKIN: Immediately wash with soap and plenty of water for at least 5 minutes. Remove contaminated clothing and shoes. Thoroughly clean contaminated clothing and shoes before reuse. Get medical attention if irritation develops or persists.
EYE: Immediately flush eyes with plenty of water for at least 15 minutes using an eyewash fountain. Lift upper and lower lids and rinse well under them. Get medical attention if irritation develops or persists.
NOTE TO PHYSICIAN: All treatments should be based on observed signs and symptoms of distress in the patient. Consideration should be given to the possibility that overexposure to materials other than this product may have occurred. Treat symptomatically. No specific information found.
VI REACTIVITY DATA
Conditions to Avoid: Dusting conditions, electric arcs, open flame, spark. Air and moisture sensitive.
Incompatibility (Material to Avoid): Strong acids, strong oxidizing materials, halogens, acid chlorides, water/moisture and air.
Hazardous Decomposition Products: Powder: Contact with water liberates extremely flammable gases (metal oxide fume).
Hazardous Polymerization: Will not occur.
VII SPILL OR LEAK PROCEDURES
Steps to be Taken in Case Material is Released or Spilled: Eliminate all sources of ignition. Evacuate area. Wear appropriate protective gear. Sweep into appropriate container. Avoid creating dust. Do not use "shop" vacuum as this may cause a fire. Ventilate area. Wash spill area with water after material pickup is complete.
Waste Disposal Method: Dispose of in accordance with Local, State and Federal regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: In dusting conditions, use a NIOSH/MSHA approved dust mask.
Ventilation: Provide adequate ventilation. Use local exhaust as needed to maintain airborne exposure below control limits.
Protective Gloves: Recommended
Eye Protection: Safety glasses with side shields. Chemical workers Dust-Proof Goggles (under dusting conditions).
Other Protective Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a cool, dry place in tightly closed containers. Air and moisture sensitive. Store away from oxidizers and other materials listed under incompatibility. STORE UNDER ARGON OR OTHER INERT ENVIRONMENT. Avoid breathing dusts. Avoid direct or prolonged contact with skin and eyes. Do not rub eyes with soiled hands.
Other Precautions: Avoid creating dusts as this product, like most materials in powder form, is capable of creating a dust explosion. Use non-sparking tools and grounded/bonded equipment and containers when transferring. Foils are subject to oxidation at elevated temperatures and will deteriorate in the presence of moisture. Will 'fingerprint' easily. Pinholes may occur in thin foils as metal ages.
Work Practices: Do not store, use, and/or consume foods, beverages, tobacco products, or cosmetics in areas where this material is stored. Wash hands and face carefully before eating, drinking, using tobacco, applying cosmetics, or using the toilet. Wash exposed skin promptly to remove accidentally splashes of contact with this material. Maintain a sink, safety shower and eyewash fountain in the work area. Have oxygen readily available.
Warning Statements: FLAMMABLE SOLID WHEN IN A POWDER OR THIN FOIL. ALL FORMS WILL REACT WITH DILUTE ACIDS EMITTING FLAMMABLE/EXPLOSIVE HYDROGEN GAS.
TSCA Inventory Status: Product is TSCA certified.
Transportation Status: Powder and Thin Foil: Flammable solid, n.o.s. (dysprosium metal), UN 3089.
Ingot and Chunk: Not regulated.
