V HEALTH HAZARD INFORMATION
Exposure Limits in Air: (TLV or suggested control figure):
Chemical Name(s): ACGIH (TLV): OSHA (PEL):
10 mg/m3 15 mg/m3
Particulates
Not otherwise (TWA) total dust
5 mg/m3 respirable
Regulated total dust
Effects of Single Overexposure:
Swallowing: Studies performed on mice have shown rare earth chlorides to have low toxicity. Hydrates of rare earth chlorides are
not tolerated as well after ingestion. LD50 (mouse) anhydrous: 4417 (mg/kg)
Skin Absorption: No data found
Inhalation: No data found for rare earth chlorides. Good industrial hygiene practice recommends limiting exposure to all respirable
particulates.
Skin Contact: SEVERE IRRITANT ON ABRADED SKIN. Studies on this and other rare earth chlorides have shown these materi-
als to be non-irritating to intact skin but extremely irritating to abraded skin.
Eye Contact: SEVERE EYE IRRITANT. Studies on this and other rare earth chlorides have shown these materials to be very
irritating to the eye.
Effects of Repeated Overexposure: No toxic effects noted after chronic oral exposure in studies performed on animals.
Carcinogenicity: This product does not contain any ingredient designated by IARC, NTP, ACGIH, or OSHA as a probable human
carcinogen.
Significant Laboratory Data With Possible Relevance to Man: No additional data found.
Medical Conditions Possibly Aggravated by Overexposure: No additional data found.
EMERGENCY AND FIRST AID PROCEDURES:
EYES: In case of contact, 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 immediate medical attention, preferably an eye specialist.
SKIN: In case of contact, 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.
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 medical attention.
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
Conditions to Avoid: Dusting conditions
Incompatibility (materials to avoid): Strong acids, strong oxidizing materials, strong bases.
Hazardous Decomposition Products or Byproducts: Toxic fumes of hydrogen chloride gas are released at decomposition tempera-
tures.
Hazardous Polymerization: Will not occur
VII SPILL OR LEAK PROCEDURES
Steps to be Taken in Case Material is Released or Spilled: Wear appropriate protective gear. Sweep up into appropriate container
for disposal or recovery. Avoid creating dusting conditions. Ventilate area. Neutralize spill area with calcium carbonate hydroxide
solution.
Waste Disposal Method: Dispose of in accordance with Local, State and Federal regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: Under conditions requiring respiratory protection use a NIOSH/MSHA approved air purifying respirator
with particulate filter.
Ventilation: Provide adequate ventilation. Use local exhaust as needed.
Protective Clothing: Work uniform and gloves.
Eye Protection: Chemical Workers goggles.
Other: DO NOT WEAR CONTACT LENSES.
Other Protective Equipment: Maintain a sink, safety shower and eyewash fountain in the work area. Have oxygen readily avail-
able.
IX SPECIAL PRECAUTIONS
Other Handling and Storage Conditions: SEVERE EYE IRRITANT. SEVERE IRRITANT TO ABRADED SKIN. HYGRO-
SCOPIC. Store in tightly closed containers in cool dry place. Avoid breathing dusts. Avoid all direct contact with skin and eyes.
Change contaminated clothing promptly and launder before reuse. Wash hands thoroughly after handling. Do not rub eyes with
soiled hands. Do not eat, drink or smoke in the work area.
Other Precautions: Dry powders can build static electricity charges when subjected to the friction of conveying, mixing or sliding.
To prevent ignition, provide adequate precautions, such as electrical grounding, or inert atmospheres when material is used in the
presence of flammable materials.
Regulatory Status: TSCA Inventory Status: Product is TSCA certified. Listed under CAS #: 10138-41-7 for anhydrous erbium
chloride.
