Inhalation: Remove to fresh air, seek medical attention if symptoms persist, provide artificial respiration if breathing has stopped
Skin Contact: Remove contaminated clothing, wash skin thoroughly with soap and water, seek medical help for irritation
Eye Contact: Rinse thoroughly with plenty of water for at least 15 minutes, consult a physician
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention, provide information about substance ingested
Important Symptoms/Effects: Burning sensation, coughing, shortness of breath, irritation to eyes, nose, throat, abdominal pain if ingested
Suitable Extinguishing Media: Use dry sand, dry chemical, carbon dioxide, do not use water or foam
Specific Hazards: Tungsten(VI) Chloride reacts with water and liberates toxic and corrosive hydrogen chloride gas, generates dense white smoke
Protective Equipment: Wear self-contained breathing apparatus, chemical protective clothing
Special Precautions: Remove containers from fire area if it is safe, avoid inhaling gases/fumes/vapors generated, contain runoff to prevent environmental contamination
Personal Precautions: Use personal protective equipment, ventilate area, avoid breathing vapors or dust, prevent contact with skin and eyes, restrict access to affected area
Environmental Precautions: Prevent product from entering drains, surface water or groundwater, contain spillage with sand or vermiculite
Cleanup Methods: Use non-sparking tools, sweep up and shovel material, place in appropriate waste container for disposal, avoid all water contact, ventilate area after cleanup
Disposal: Dispose as hazardous waste according to local, state and national regulations
Handling: Handle only in well-ventilated areas, avoid formation and inhalation of dust and vapors, wear recommended personal protective equipment, keep away from moisture and incompatible substances, do not eat, drink or smoke near material, wash hands thoroughly after use
Storage: Store in tightly sealed containers, keep away from humidity, water, heat, and sources of ignition, store in cool, dry, well-ventilated area, separate from acids and oxidizing agents, clearly label storage containers, store away from food and drink
Exposure Limits: No workplace exposure limits set specifically for this substance; use local and national guidelines for similar respiratory and skin irritants
Engineering Measures: Ensure adequate ventilation, use fume hoods and emergency eyewash/shower stations
Respiratory Protection: Wear approved respirators if potential for exposure to dust or fumes exists

Routes of Exposure: Inhalation, skin and eye contact, ingestion
Symptoms: Irritation to respiratory tract, severe eye and skin burns, abdominal pain if swallowed, potential long-term health effects from chronic exposure, suspected mutagenicity
Acute Toxicity: LD50 (oral, rat): not well established but estimated to be in low hundreds mg/kg
Skin Sensitization: May cause allergic reactions, dermatitis
Carcinogenicity: Not listed by IARC, NTP, or OSHA as carcinogenic, but data is limited
Other Data: May cause damage to lungs, kidneys, and central nervous system over repeated exposure
Aquatic Toxicity: Very toxic to aquatic life, releases hydrochloric acid upon reaction with water which harms fish and invertebrates
Persistence and Degradability: Not readily biodegradable, persistent in environments without water
Bioaccumulation Potential: Not expected to bioaccumulate extensively, but tungsten compounds can persist
Mobility in Soil: Reacts quickly to form tungsten oxides and hydrochloric acid, may bind to soils in presence of moisture
Other Data: Avoid environmental release, hazardous to soil microorganisms and plants due to its corrosive and toxic residues
Methods of Disposal: Handle as hazardous waste, do not release into environment, contact licensed chemical disposal contractor
