IV FIRE AND EXPLOSION H AZARDS DATA

Flash Point: N/A Autoignition Temperature: N/A
Flam mab le Limits: Lower: N/A Upper: N/A

Extingu ishing 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 w ill burn under fire conditions. May react with water liberating flammable,
exp losive hyd rogen gas. Th in foils m ay ignite by spa rk or static electricity. Like m ost dry chem icals, in a p ow der o r 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.
Chro nic Effects: No data found.

Carcino genicity: NTP: No IARC: No AC GIH : No OSHA: No
Medical Conditions Possibly Aggravated by O verexposure: No data found.

EMERG ENCY 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 imm ediately by giving two glasses of water and sticking
finger down throat. GET IMMEDIATE MEDICAL ATTENTION.
SK IN: Imm ediately wash w ith soap and plenty o f water for at least 5 m inutes. Rem ove contaminated clothing and sh oes.
Tho roug hly clean contam inated clothing and shoes before reu se. Get m edical attention if irritation develops or persists.
EYE: Imm ediately flush eyes with plenty of water for at least 15 minutes using an eyewash fountain. Lift upper and lower lids and
rinse we ll under them. G et med ical 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

Stability: Stable

Co nditio ns to Av oid: Dusting conditions, electric arcs, open flame, spark. Air and moisture sensitive.
Incompatibility (Material to Avoid): Strong acids, strong ox idizing materials, halogens, acid chlorides, water/moisture and air.

Haz ardous D ecomposition Produc ts: Powder: Con tact with water liberates extremely flamm able gases (metal oxide fum e).
Hazardous Polymerization: Will not occur.


VII SPILL OR LEAK PROC EDURES

Steps to be Taken in Case Material is Released or Spilled: Elim inate all sourc es of ig nition. Eva cuate area. We ar appropriate
protective gear. Sweep into ap propriate container. Avoid creating du st. Do not u se "shop" vacu um as this m ay ca use a fire. Ventilate
area. Wash spill area with water after material pickup is complete.

Waste Disposal Method: Dispose o f in accord ance w ith Loca l, State and Federal regu lations.


VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection: In dusting conditions, use a NIOSH/MSHA approved dust mask.
Ventilation: Provide adequ ate ventilation. U se local exh aust as need ed to m aintain airborne exposure below control lim its.

Protective Gloves: Recommend ed
Eye Protection: Safety glasses with side shields. Chemical workers D ust-Proof Gog gles (under dusting cond itions).

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 mo isture
sensitive. Store away from oxidizers and other materials listed under incompatibility. STORE UNDER ARGO N OR OTHER INERT
EN VIR ON MEN T. A void breathing dusts. A void direct or prolon ged contact with skin and eyes. Do not ru b eyes with soiled hands.

Other Precautions: Avoid creating du sts as this product, like mo st ma terials in p ow der fo rm, is capable of creating a dust explo sion.

-Dysprosium 2-
Use non-sparking tools and grounded/bonded equipment and containers when transferring. Foils are subject to oxidation at elevated
temp eratures an d will deteriora te in the presen ce of m oisture. W ill 'fingerprint' easily. Pinholes m ay occ ur in thin foils as metal ages.

Wo rk Practices: Do not sto re, use, and/or co nsume foods, be verages, tobacco products, or cosm etics in areas w here this m aterial is
stored. Wash hands and face carefully before eating, drinking, using tobacco, applying cosmetics, or using the toilet. Wash exposed
skin p rom ptly to rem ove accid entally splash es of contact with this m aterial. M aintain a sink, safety show er and eyewash fo untain in
the work area. Have oxygen readily available.

W arning Statem ents: FLAMMABLE SOLID WHEN IN A POWDER OR THIN FOIL. ALL FORMS WILL REACT WITH
DILUTE A CIDS EMITTING FLAM MA BLE/EXPLOSIVE H YDRO GEN G AS.

TSCA Inventory Status: Product is TSCA certified.

Transportation Status: Powd er an d Th in Fo il: Flammable solid, n.o.s. (dysprosium metal), UN 3089.
Ingot and Chunk: Not regulated.

The abo ve inform ation is believ ed to be co rrect, but do es no t purp ort to b e all inclu sive an d sha ll be used only as a gu ide.
ESPI shall not be held liab le for any d am age resulting from h and ling o r from contact with the abov e pro duc t.
