V.   HEALTH HAZARD INFORMATION

Effects of Exposure:

To the best of our knowledge the acute and chronic toxicity of hexachloroplatinic acid is not fully known.  Exposure to platinum containing dusts or fumes may cause irritation, sensitization reactions and asthma.  Effects include sneezing, coughing, tightness in the chest, dyspnea and wheezing.  Cyanosis is possible.  Chronic exposure may result in pulmonary fibrosis.  Swallowing will lead to a strong corrosive effect on mouth and throat and to the danger of perforation of esophagus and stomach.

Carcinogenicity:  No classification data on carcinogenic properties of this material is available from the EPA, IARC, NTP, OSHA or ACGIH.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION:  Remove patient to fresh air.  Seek immediate medical advice.

INGESTION:  Seek immediate medical advice.

SKIN:  Flush with soap and water for 15 minutes.  Seek immediate medical advice

EYE:  Flush with eye bath.  Consult a physician

NOTE:  Platinum compounds, especially platinum halogen complexes, are sensitizers.  Sensitized persons, on re-exposure to platinum salts, will show the clinical features of a type 1 allergy: asthma and/or rhinitis and/or conjunctivitis and/or urticaria (hives).  A contact dermatitis may also occur.  The symptoms of the allergic reaction to platinum salts may include any of the following: itchy red eyes, watering of the eyes, sneezing, runny nose, chest tightness, wheezing, breathlessness, cough, eczematous or urticarial (nettle rash type) skin lesions.  Exposure to platinum salts in exceedingly small amounts, even below the level of physicochemical detection, will produce symptoms in sensitized persons.  Continued exposure will give symptoms of increasing severity and can eventually lead to chronic asthma.  There is a risk of anaphylactic shock occurring in sensitized persons re-encountering platinum salts.  Therefore, if sensitization has developed, further exposure to platinum compounds must not be permitted.

VIII.   SPECIAL PROTECTION INFORMATION

Respiratory Protection:  Use suitable respirator when high concentrations are present.

Ventilation: Handle in a controlled, enclosed environment in an inert gas such as argon.  Use local exhaust to maintain low levels of exposure.  General exhaust is recommended.

Protective Gloves:  Rubber for all contact

Eye/Face Protection:  Goggles

Other Protective Equipment:  Protective work clothing

IX.   SPECIAL PRECAUTIONS

Precautions to Be Taken in Storage and Handling:  Store in cool dry place.  Keep tightly sealed when not in use.  Wash thoroughly after handling.  Prevent formation of dust.

Work Practices:  Implement engineering and work practice controls to reduce and maintain concentration of exposure.  Use good housekeeping and sanitation practices.  Do not use tobacco or food in work area.  Wash thoroughly before eating or smoking.  Do not blow dust off clothing or skin with compressed air.  Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
