V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of neodym ium oxide have not been
thoroughly investigated and recorded.
Neodymium is considered a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the
rare earth elements include writhing , ataxia, labored re spiration, walking on toes w ith arch ed back and sedation. T he rare earth
elem ents ex hibit low toxicity b y ing estion exposure. How ever, the intraperitone al rou te is high ly tox ic wh ile the su bcu taneo us route
is poiso n to m ode rately toxic. The produc tion o f skin and lung gran ulom as after exposure to them requ ires extensive pro tection to
prevent such exp osure (Sax, Dan gerous Prope rties of Industrial Materials, eighth edition).
Acute E ffects:
Inhalation: May cause irritation to the respiratory tract and mucous membrane. Dusts may cause asthma attacks and lung damage
such as lung granulomas. Large doses may cause writhing, loss of muscle coordination, labored respiration, sedation, hypotension
and cardiovascular collapse.
Ingestion: May cause gastrointestinal irritation.
Skin : Ma y cau se irritation , rashes and skin g ranu lom as.
Eye: May cause irritation.
Chro nic Effects:
Inhalation: Prolonged or repeated inhalation may cause writhing, loss of muscle coordination, labored respiration, sedation,
hypotension and cardiovascular collapse.
Ingestion: May affect the coagulation rate of blood.
Skin : May cause dermatitis, sensitivity to heat, itching and skin lesions.
Eye: No Chronic health effects recorded.
Routes of Entry: Inhalation, Skin, Eyes, Ingestion.
Medically Conditions Generally Aggravated by Exp osure: Pre-existing respiratory disorders
Target Organs: May affect the respiratory system, blood and skin.
Carcino genicity: NTP: N IARC M onographs: N OSH A Regulated: N
EMERG ENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim from exposure. 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.
SK IN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention
if irritation persists.
EYE: Flush eyes with lukewarm water, lifting u ppe r and lower eyelids fo r at least 15 m inutes. Seek me dical attention if
irritation persists.
VI REACTIVITY DATA

VII SPILL OR LEAK PROC EDURES
Steps to Be Taken in Case Material Is Released or Spilled: We ar appropriate respira tory and protective equipm ent specified in
Section VIII-Special Protection Information. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency
particulate absolute (H EPA) air filter and place in a closed container fo r proper d isposal. Tak e care not to raise dust.
Waste Disposal Method: Dispose o f in accord ance w ith Loca l, State and Federal regu lations.
VIII SPECIAL PROTECTION INFORMATION
-Neodymium Oxide 2-
Respiratory Protection (Specify Type): NIOSH approved dust respirator.
Ventilation: Use lo cal exhau st to m aintain concentration at low exposure levels. Handle and store in an inert gas, such as argon.
Handle in a dry, controlled atmosphere. Mechanical (general) exhaust is not 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 a cool dry place in a tightly sealed container. Wash thoroughly after
handling.
Other Precautions: Neodymium oxide is hygroscopic. Handle and store in an inert gas such as argon.
Wo rk Practices: Imp lem ent en gineering and wo rk practice controls to re duc e and ma intain c onc entration o f exp osure at low levels.
Use good housekeeping an sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and
smok ing. Do not blow dust off clothing or skin with comp ressed air.
