Ld50 lc50 mixture: acgih recommended limit 5 mg/m3
routes of entry: inhalation: yes skin: no ingestion: no
reports of carcinogenicity: ntp: no iarc: no osha: no
health hazards acute and chronic: although the inhalation of tungsten
has the potential for causing transient or permanent lung damage,
it is generally considered to exhibit a low degree of toxicity.
considerable experience in refinin g and use of thorium has not has
not revealed any adverse effects from industrial exposure.
effects of overexposure: short-term (acute) overexposure to welding
fumes may result in discomfort such as dizziness, nausea, or
dryness or irritation of the nose, throat, or eyes. long-term
(chronic) overexposure to welding fumes can lead to siderosis
(iron in lungs) and affect pulmonary function.
medical cond aggravated by exposure: allergic reaction is possible in
sensitive individuals; however, such reaction cannot be predicted
due to variation in composition and quantity of the decomposed
products.
First aid: call for medical aid. Employ first aid techniques recommended
by the american red cross. If breathing is difficult, give oxygen.
call a physician. In case of electrical shock disconnect and turn
off p ower. If not breathing, begin artificial respiration,
preferably mouth-to-mouth. If no detectable pulse, begin external
heart massage, immediately call a physician. For arc burn, call a
physician.
