Molecular Weight: 485.99 g/mol
Appearance: Bright yellow-orange crystalline solid
Inhalation: Remove exposed person to fresh air, monitor for signs of respiratory distress, seek medical attention if coughing, shortness of breath, or other symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water, wash thoroughly with soap, seek immediate medical attention because platinum compounds can trigger allergic reactions
Eye Contact: Rinse eyes with running water for at least 15 minutes while keeping eyelids open, remove contact lenses if present, call physician without delay
Ingestion: Do not induce vomiting, rinse mouth, never give anything by mouth to an unconscious person, get immediate medical assistance as this compound is highly toxic
Note to Physicians: Treat symptomatically, monitor for allergic and anaphylactic reactions, supportive care and oxygen may be required
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or foam extinguishers, do not use water jet because of potential spattering and contamination risks
Specific Hazards: Product does not burn but hazardous decomposition produces toxic chlorine and platinum fumes in a fire, smoke may irritate respiratory tract
Protective Equipment: Firefighters need full protective gear including self-contained breathing apparatus, chemical resistant gloves, and eye protection
Special Procedures: Move containers from fire area if safe to do so, avoid runoff to sewer or water systems
Personal Precautions: Restrict access to area, ventilate space, wear full personal protective equipment (gloves, lab coat, goggles, appropriate respiratory mask); evacuate unprotected personnel
Environmental Precautions: Prevent entry to sewers, surface waters, and soil, informed local authorities in case of large releases
Methods for Cleanup: Sweep up solids carefully to minimize dust, use wet methods when possible to collect residue, transfer material into secure waste containers with appropriate labeling, decontaminate surrounding surfaces with suitable cleaning agents, dispose of waste in accordance with regulatory guidelines
Handling: Handle only in well-ventilated area or fume hood, avoid generation and inhalation of dust, wear personal protective equipment, avoid skin and eye contact, keep food and beverages away from work zone
Storage: Store in tightly closed containers in a cool, dry, well-ventilated, and secure area clearly marked for toxic materials, keep away from incompatible substances such as acids, alkalis, and combustibles, use secondary containment in areas at risk of spillage, keep a chemical spill kit nearby
Occupational Exposure Limits: Platinum Salt Compounds (as Pt): ACGIH TLV 0.002 mg/m3 (TWA, inhalable fraction)
Engineering Controls: Local exhaust ventilation and full enclosure in fume hood or glove box for open operations, installation of eyewash stations and safety showers near work area
Personal Protective Equipment: Nitrile or neoprene gloves, long-sleeve lab coat, chemical splash goggles, and disposable respirators (minimum P2/N95 or higher efficiency respirators)

Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Effects: Severe irritation to mucous membranes, fatal if swallowed, highly toxic by inhalation; rapid onset of respiratory symptoms, skin or eye allergies common among sensitized individuals
Chronic Effects: Chronic exposure may cause systemic toxicity, allergic asthma, skin sensitization, respiratory tract sensitization, potential kidney and liver damage
LD50 Oral (rat): approx. 10-20 mg/kg [value varies by source]
Carcinogenicity: Not listed by IARC or NTP as carcinogenic, but prolonged contact with soluble platinum compounds can provoke severe allergic reactions
Other Information: Platinum salts among the most potent known chemical sensitizers, even small exposures can trigger responses in sensitive individuals
Ecotoxicity: Highly toxic to aquatic life, platinum compounds persist in sediments, can bioaccumulate in organisms, disrupt aquatic ecosystem balance
Persistence and Degradability: Non-biodegradable, remains in environment for extended periods
Bioaccumulation Potential: Bioaccumulative in some aquatic species; higher trophic levels may be affected over time
Mobility in Soil: Moderately mobile under acidic conditions, binds to soil under neutral to basic pH
Other Adverse Effects: Discharge into water bodies can damage aquatic organisms and disrupt food chains
Waste Treatment Methods: Must be disposed of as hazardous waste according to local, state, and national regulations; collection in sealed, properly labeled containers; avoid release into environment
Disposal of Contaminated Packaging: Rinse containers with water, collect rinsate for chemical waste treatment, do not reuse containers
Additional Precautions: Notify licensed hazardous waste disposal contractor, maintain proper manifest and tracking records for all waste transfers, document destruction and neutralization where appropriate
