VI HEALTH HAZARD DATA
Routes of Entry: Inhalation, Skin, Eyes, Ingestion
Health Hazards (acute and chronic):
To the best of our knowledge the chemical, physical and toxicological properties of palladium oxide have not been thor-
oughly investigated and recorded. May be a skin sensitizer. In the laboratory, palladium appears to bind to many cell components;
blocks the action of a number of enzymes and interferes with use of energy by nerves and muscles; induces lung malfunction and
produces abnormal fetuses. Lethal intravenous doses cause appetite loss, hemolysis, renal deposition and bone marrow damage (Sax,
Dangerous Properties of Industrial Materials, eighth edition).
Inhalation: Acute: Inhalation of dust or powder may cause abrasive irritation to the respiratory system.
Chronic: May induce lung malfunction and produce abnormal fetuses.
Ingestion: Acute: Poorly absorbed by the body when ingested.
Chronic: No Chronic health effects recorded.
Skin: Acute: May cause abrasive irritation and possibly may be a skin sensitizer.
Chronic: No chronic health effects recorded.
Eye: Acute: May cause abrasive irritation.
Chronic: No chronic health effects recorded.
Target Organs: No target organs recorded
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders.
Carcinogenicity: NTP: No IARC Monographs: No OSHA Regulated: No
Recommended Exposure Limits: See鈥漇ection 2"
LD50/LC50: No toxicity date recorded
Signs and Symptoms of Exposure:
Inhalation: May cause red, dry throat and coughing.
Ingestion: No acute or chronic health effects recorded.
Skin: May cause redness and itching
Eye: May cause redness, itching and watering
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air; keep warm and quiet; give oxygen if breathing is difficult and seek medical attention if
INGESTION: Not Applicable.
SKIN: Remove contaminated clothing; brush material off skin; wash affected area with mild soap and water; seek medical attention
if symptoms persist.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids for at least 15 minutes. Seek medical attention if symptoms
VII PRECAUTIONS OF SAFE HANDLING AND USE
Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment specified in
Section VIII-Special Protection Information. 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: Dispose of in accordance with Local, State, and Federal Regulations.
Hazard Label Information: Store in a cool, dry area in a tightly sealed container. Wash thoroughly after handling.
Precautions to Be Taken in Handling and Storing: None
Other Precautions: None
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): NIOSH approved dust-mist-vapor respirator.
Ventilation: Local Exhaust: To maintain concentration at low exposure levels Mechanical (General): Recommended
Special: None Other: None
Protective Gloves: Rubber gloves Eye Protection: Safety glasses
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination
Work/Hygienic/Maintenance 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 areas. Wash thor-
oughly before eating and smoking. Do not blow dust off clothing or skin with compressed air.
