V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of tungsten chloride have not been
thoroughly investigated and reported.
Tungsten compoun ds may be irritating to the eyes and respiratory tract. Animal studies suggest that soluble tungsten
com pou nds ha ve the p otential for cau sing adv erse health effects involving the gastrointestinal tract and c entral nerv ous system . These
effects have not been observed in humans. Chronic exposure to tungsten compounds m ay result in permanent lung damage.
Inhalation: SEVERE IRRITAN T AN D CO RROSIV E. Chronic exposure may result in permanent lung damage.
Ingestion: SEV ER E IR RIT AN T A ND CO RROS IVE . Swallow ing w ill lead to a strong corrosiv e effect on mo uth and th roat and to
the danger of perforation of esophagus and stomach.
Skin : SEV ERE IRRIT AN T A ND CO RRO SIVE to skin and m ucou s mem branes.
Eye: SEVERE IRRITANT AND CORROSIVE.
Medical Conditions, if any, Aggravated by the Chemical: No data
Carcino genicity: NTP: No IARC: No OSHA: No
EMERG ENCY AND FIRST AID PROCEDURES
INHALATION: Remove victim to fresh air. Keep warm and quiet. Give oxygen if breathing is difficult and seek medical attention.
INGESTION: Do not induce vomiting. Seek medical attention immediately.
SK IN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water. Seek medical attention.
