V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the chemical, physical and toxicological properties of tetraamminepalladium chloride have not been thoroughly investigated and reported.

Palladium metal 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.

The chloride ion generally has a very low toxicity.

Ammonia gas is irritating to eyes and mucous membranes of the respiratory tract.  Irritation of the skin may be experienced, especially if it is moist.  Corneal ulcers have been reported following splashing of ammonia water in the eye.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove patient from area of exposure to fresh air.  Seek medical advice.

INGESTION:  Contact a physician immediately.

SKIN:  Flush with soap and water for 15 minutes.

EYES:  Flush with eye bath, including under eyelids, for at least 15 minutes.
