Special Firefighting Procedures:  Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.  Fumes from fire are hazardous.  Isolate runoff to prevent environmental pollution.

Unusual Fire and Explosion Hazards:  Emits toxic fumes of chlorine when heated to decomposition.




Health Hazards:

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

Exposure to complex platinum salts has been shown to cause symptoms of intoxication such as wheezing, coughing, running of the nose, chest tightness, shortness of breath and cyanosis.  Furthermore, many people working with platinum salts are troubled with dermatitis.  They may become sensitized after years of exposure.  Symptoms of platinum allergy include rhinitis, conjunctivitis, asthma, urticaria and contact dermatitis (Sax, Dangerous Properties of Industrial Materials, eighth edition).

Chlorides vary widely.  Sodium chloride (table salt) has very low toxicity, while carbonyl chloride (phosgene) is lethal in small doses (Sax, Dangerous Properties of Industrial Materials, eighth edition).

Acute Effects:

Inhalation:  May cause irritation to the respiratory system, nose, throat, lungs and mucous membranes.

Ingestion:  Poison by ingestion.

Skin:  May cause irritation.

Eyes:  May cause irritation.

Chronic Effects:

Inhalation:  May cause wheezing, dyspnea, cyanosis and lymphocytosis.

Ingestion:  No chronic health effects recorded.

Skin:  May cause dermatitis and sensitization.

Eye:  No chronic health effects recorded.

Target Organs:  May affect the respiratory system, eyes and skin.

Medical Conditions Generally Aggravated by Exposure:  Pre-existing respiratory and skin disorders.

CarcinogenicityNTP?  No      IARC Monographs?  No       OSHA Regulated:  No

Symptoms of Exposure:

Inhalation:  May cause burning sensation, nausea, sneezing, coughing, difficulty breathing and choking.

Ingestion:  May cause nausea, vomiting, and burning.

Skin:  May cause redness, itching and burning.

Eyes:  May cause redness, itching, burning and watering.



EYES:  Flush with copious amounts of water for at least 15 minutes, lifting both upper and lower eyelids.  Seek medical attention immediately.

SKIN:  Remove any contaminated clothing, brush material off of skin, flush with running water, wash carefully with soap and water.  Seek medical attention.

INHALATION:  Remove to fresh air.  Keep victim warm and quiet, give oxygen if breathing is difficult.  Seek medical attention.

INGESTION:  Give 1-2 glasses of milk or water, DO NOT induce vomiting, seek immediate medical attention.  Never give anything by mouth to an unconscious person.

Other:  None

Protective Gloves:  Neoprene

Eye Protection:  Safety glasses

Other Protective Equipment:  Wear protective clothing to prevent contamination of skin and clothes.

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 area.  Wash thoroughly before eating and smoking.  Do not blow dust off clothing or skin with compressed air.




Handling and Storage:  Keep container tightly closed.  Store in a cool dry, well-ventilated area.  Wash thoroughly after use.
