Explosion Limits: Lower: N/E     Upper: N/E

Extinguishing Media: Use suitable extinguishing media for surrounding material and type of fire.

Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.

Unusual Fire and Explosion Hazards: May emit toxic fumes of nitrogen oxide, hydrogen chloride, ammonia and/or metal oxide in case of fire.

V           HEALTH HAZARD INFORMATION

Effects of Over Exposure:

              Ammonium hexachloroosmate is a mucous membrane irritant and a corrosive solid which may cause chemical burns to skin. Oxidation of osmium compounds may form the volatile and highly irritating osmium (VIII) oxide (OsO₄). Exposure may cause bronchitis and dermatitis. OsO₄ may also cause ocular disturbances and temporary loss of night vision.

Acute and Chronic Effects:

Inhalation: May cause irritation of the respiratory tract and mucous membranes.

Ingestion: May cause irritation of the gastrointestinal tract and mucous membranes.

Skin: May cause irritation and chemical burns.

Eye: May cause irritation and temporary loss of night vision.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Supply fresh air. If required, provide artificial respiration. Keep patient warm. Seek immediate medical advice.

INGESTION: Seek immediate medical advice.

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

EYES: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.

VI         REACTIVITY DATA

Stability: Stable

Conditions to Avoid: Extreme heat, humidity/moisture.

Incompatibility (Materials to Avoid): Acids, oxidizing agents, metal powders, organic solvents.

Hazardous Decomposition Products: OsO₄, nitrogen oxides, hydrogen chloride, ammonia, toxic metal oxide fume.

Hazardous Polymerization: Will not occur

VII        SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective clothing specified in section VIII. Isolate spill and provide ventilation. Sweep up and place in airtight plastic container. Take care not to raise dust.
