Inhalation: Move the exposed person to fresh air. If breathing difficulties appear, seek emergency medical attention. Oxygen administration and artificial respiration may be necessary.
Skin Contact: Rinse thoroughly with water for at least 20 minutes, remove contaminated clothing. Immediate medical intervention is vital for chemical burns.
Eye Contact: Immediately flush with water for a minimum of 15 minutes while holding eyelids apart, do not allow victim to rub eyes. Immediate ophthalmological examination required.
Ingestion: Do not induce vomiting. Rinse mouth thoroughly. Seek urgent medical attention due to risk of severe poisoning.
Symptoms: Burning sensation, coughing, shortness of breath, severe irritation or damage to eyes and mucous membranes, allergic reactions, abdominal pain, intensive skin irritation
Suitable Extinguishing Media: Water spray, dry powder, carbon dioxide, foam. Use agents suitable for adjacent fire types.
Unsuitable Media: Avoid strong water jets.
Hazardous Combustion Products: Hydrogen chloride, platinum compounds, chlorine
Special Protective Equipment: Use self-contained breathing apparatus and full protective suit.
Special Hazards: Formation of toxic fumes under fire conditions. Avoid inhalation of dust, vapor, or combusted product.
Firefighting Instructions: Evacuate area, approach fire upwind, stay clear of smoke, water runoff may be acidic and should be contained.
Personal Precautions: Evacuate unprotected personnel, ensure proper ventilation, wear respirator, gloves, and goggles.
Spill Response: Prevent further leakage if safe, contain with sand or inert absorbent. Collect solid or liquid carefully to minimize powder generation.
Cleaning Methods: Vacuum up with HEPA filter or wet methods; never use a standard broom or dry sweeping to avoid dust. Dispose collected material in accordance with official regulations.
Environmental Precautions: Prevent entry into waterways, sewers, or soil. Notify authorities if environmental contamination is possible.
Decontamination: Wash area with copious water after removal to neutralize traces.
Precautions: Handle strictly with chemical-resistant gloves, protective goggles, and lab coat. Avoid creating dust, and do not ingest or inhale fumes.
Safe Practices: Keep workplace clean; work only in well-ventilated or fume-hood equipped settings.
Storage Conditions: Store locked up in tightly closed chemical-resistant containers, in a cool, dry well-ventilated space far from incompatible substances such as organic materials, alkalis, and reducing agents.
Storage Limitations: Keep away from food, beverages, and incompatible chemicals. Make sure container is properly labeled.
Handling Guidance: Open containers with care, avoid spillage, immediately rinse accidental splashes from surfaces.
Control Parameters: No established OSHA or ACGIH exposure limits for platinum chlorides, but exposure should be kept as low as possible.
Engineering Controls: Use chemical fume hood, local exhaust ventilation, safety shower, and eye wash station.
Personal Protective Equipment: Nitrile or neoprene gloves, chemical splash goggles, lab coat, appropriate respirator for airborne exposure risk.
Hygienic Measures: Wash hands thoroughly after use, remove and wash contaminated clothing before reuse.
Environmental Controls: Prevent chemical from reaching water sources or soil.
