Chemical Name: Lanthanum (III) Chloride Heptahydrate
Common Names: Lanthanum trichloride hydrate
CAS Number: 10099-58-8
Purity: Typically above 99% in laboratory grades
Major Components: Lanthanum chloride heptahydrate, trace impurities include rare earth chlorides, residues from production
Hazardous Components: Main hazards stem from the chlorides and the rare earth metal content; no major hazardous impurities present in analytical grades
Inhalation: Move affected individual into fresh air, monitor for respiratory symptoms, seek immediate medical attention if symptoms worsen or persist
Skin Contact: Remove contaminated clothing and rinse skin thoroughly with plenty of running water for at least 15 minutes, use mild soap, obtain medical advice if irritation continues
Eye Contact: Flush eyes for at least 15 minutes under gently running water while holding eyelids open, remove contact lenses, pursue prompt medical evaluation
Ingestion: Rinse mouth thoroughly, drink water only if not unconscious, never induce vomiting unless directed by medical personnel, get to an emergency facility promptly
Other Notes: Rescue workers need protective equipment; symptomatic treatment should follow standard toxicology best practices
Suitable Extinguishing Media: Use dry powder, carbon dioxide, foam, or sand, avoid water jets which may spread contamination
Specific Hazards: Can decompose under intense heat releasing hydrogen chloride and lanthanum oxides, hazardous gases may be released under combustion
Protective Equipment: Firefighters should use self-contained breathing apparatus and full chemical protective gear
Firefighting Instructions: Isolate hazard area, evacuate non-essential personnel, contain runoff to prevent environmental release, cool containers exposed to flames with water spray
Fire Residue Disposal: Collect residues carefully for regulated disposal, avoid inhalation or contact
Personal Precautions: Evacuate unprotected personnel, ventilate area, avoid dust formation, apply appropriate PPE such as gloves, eye protection, lab coats or full coveralls
Environmental Precautions: Prevent further spillage or leakage into drains, soil, or aquatic systems, use barriers to contain spread
Containment: Collect spilled material by using HEPA-filtered vacuum, spade, or damp cloths, avoid sweeping or dry brushing to limit airborne dust generation
Cleanup Methods: Pick up carefully and deposit in a suitable waste container for transport according to local Hazardous Waste Regulation
Post-Cleanup: Clean spill site with water and mild detergent, discard cleaning materials as chemical waste
Handling Practices: Work in designated chemical fume hoods or well-ventilated areas, avoid creating dust, wear fitting protective gear, wash hands before breaks and at end of workday, avoid eating or drinking near open product
Storage Conditions: Store in tightly closed containers, away from incompatible substances like strong oxidizers or acids, keep in a cool, dry, and well-ventilated area, avoid exposure to high heat or moisture
Incompatibilities: Do not store beside strong acids, oxidizers or moisture-sensitive materials, strictly separate from food and feed
Packaging Advice: Use corrosion-resistant, clearly labeled sealed containers; containers should be checked regularly for leaks or damage
Engineering Controls: Use chemical fume hoods, install local exhaust ventilation, maintain negative pressure in handling rooms
Occupational Exposure Limits: No established standard for lanthanum chloride heptahydrate but minimize exposure as for nuisance particulates, observe ACGIH TLV for inhalable particulates not otherwise classified (10 mg/m3)
Respiratory Protection: Approved respirators or dust masks for operations creating dust or aerosol, use full-face particulate respirators for high concentrations
Skin Protection: Nitrile, neoprene, or rubber gloves, long-sleeved impervious clothing
Eye Protection: Safety glasses with side shields, laboratory splash goggles for higher-risk handling
Hygiene: Remove contaminated clothing at end of shift, shower thoroughly upon significant exposure, do not reuse soiled PPE without washing

Hazardous Polymerization: Does not polymerize
Acute Toxicity: Toxicity level low but can cause irritation to respiratory system, eyes, and skin; ingestion in larger amounts may result in GI distress
Skin/Eye Contact: Redness, watering, possible chemical burns on prolonged contact
Inhalation Effects: Irritation, coughing, or shortness of breath when dust is encountered
Chronic Effects: Data limited, but rare earth compounds have been associated with lung and liver effects after long-term occupational exposure
