Inhalation
IF INHALED: If breathing is difficult, remove to fresh air and keep at rest in a position comfortable for
breathing. Call a physician if symptoms occur.
Skin contact
Burns should be treated by a doctor.
Eye contact
IF IN EYES: Rinse cautiously with water for several minutes. Remove contact lenses, if present and
easy to do. Continue rinsing. Burns from radiation, see doctor.

Section 11. TOXICOLOGICAL INFORMATION
11.1 Information on toxicological effects
Conditions to avoid: none in the form supplied
When welding, fumes and gases generated can be dangerous to health.
Acute toxicology
This product does not feature an acute oral, dermal toxicity or toxicity through inhalation
Irritation
Corrosive effects
May cause sensitisation by skin contact
Welding fumes are possibly carcinogenic to humans
Repeated dose toxicity
Finding after intratracheal application of 50mg tungsten dust per week during 3 weeks on guinea pigs
lead to the conclusion that the substance is relatively inert. Still an effect on the pulmonary tissue
could be proved which must not be neglected.
Reproductive toxicity
