V HEALTH HAZARD INFORMATION

Route(s) of Entry: Inhalation? Yes Skin? No Ingestion? Yes Other? No
Health Hazards (Acute and Chronic): To the best of our knowledge the chemical, physical and toxicological properties of lantha-
num aluminate have not been thoroughly investigated and recorded.

Lanthanum 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 respiration, walking on the toes with arched back and sedation. The rare earth
elements exhibit low toxicity by ingestion exposure. However, the intraperitoneal route is highly toxic while the subcutaneous route
is poison to moderately toxic. The production of skin and lung granulomas after exposure to them requires extensive protection to
prevent such exposure (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Aluminum compounds have many commercial uses and are commonly found in industry. Inhalation of fine aluminum
oxide particles is associated with Shaver??s Disease. (Sax, Dangerous Properties of Industrial Materials, eighth edition)

Inhalation: Acute: May cause irritation to the respiratory tract and mucous membranes. Dusts may cause lung damage such as lung
granulomas and pulmonary fibrosis. Large doses may cause writhing, loss of muscle coordination, labored respiration, sedation,
hypotension, and cardiovascular collapse.
Chronic: Prolonged or repeated inhalation may cause writhing, loss of muscle coordination, labored respiration, sedation, hypoten-
sion and cardiovascular collapse.
Ingestion: Acute: May cause gastrointestinal irritation and nervous afflictions.
Chronic: May affect the coagulation rate of the blood.

Skin: Acute: May cause irritation, rashes, lesions and skin granulomas.
Chronic: May cause dermatitis.

Eye: Acute: May cause irritation.
Chronic: No chronic health effects recorded.

Target Organs: May affect the respiratory system, blood and skin.
Carcinogenicity: NTP? No IARC Monographs? No OSHA Regulated? No

Signs and Symptoms of Exposure: Inhalation - coughing. Eyes -particle irritation. Ingestion - unknown.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders

EMERGENCY AND FIRST AID PROCEDURES:

EYES: Flush eyes with lukewarm water, lifting upper and lower lids, for at least 15 minutes. Seek medical attention if irritation
persists.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical attention
if irritation persists.
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.
INHALATION: Remove to fresh air, Keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.

VI REACTIVITY DATA

VII SPILL OR LEAK PROCEDURES

Steps to be Taken in Case Material is Released or Spilled: Wear appropriate respiratory and protective equipment specified in
section VIII. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter
and place in a closed container for proper disposal. Take care not to raise dust.

Waste Disposal Method: In accordance with local, state and federal regulations.

VIII SPECIAL PROTECTION INFORMATION

Respiratory Protection: NIOSH approved dust respirator.
Ventilation: Local Exhaust: To maintain concentration at low exposure levels. Mechanical: Recommended.
Special: None Other: None

Protective Gloves: Recommended Eye Protection: If dusting occurs

Other protective Clothing or Equipment: None
Work/Hygiene Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at
low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before
eating and smoking. Do not blow dust off clothing or skin with compressed air.
IX SPECIAL PRECAUTIONS

Precautions to be Taken in Handling and Storage: Store in a tight seal, dry container.

Other Precautions: None.
