health hazards acute and chronic: light from arc can cause eye damage,
inflamation, skin damage.Tungsten dust may cause skin irritation
and permanent lung damage. Thorium oxide deposites in lungs and can
cause pulmonary fibrisis & pne umocirrhosis. Electrical shock can
kill.Exposure to dust above the nrc limits may increase the risk of
lung cancer.
explanation of carcinogenicity: thorium oxide is listed as a human
carcinogen by ntp.
effects of overexposure: dizziness, nausea,irritation of nose, throat;
medical cond aggravated by exposure: chronic respiratory diseases and
asthma may be aggravated by exposure to dusts, fume or mists.
First aid: eyes: wash with plenty of water for at least 15 minutes.See
doctor. Skin: wash with soap and water.If irritation persists,see
doctor. Inhalation: remove to fresh air.Give oxygen/cpr if
needed.See doctor. Ingestion: see doctor. Other: wounds contaminated

reports of carcinogenicity: ntp: no iarc: no osha: no
health hazards acute and chronic: short term overexposure to welding
fumes may result in discomfort such as dizziness, nausea or
irritation of nose, throat or eyes. Industrially tungsten thoria
alloy does not constitute an important h ealth hazard. Exposure is
related chiefly to the dust arising out of grinding and machining
operations. Chronic inhalation of the dust may cause damage in
humans.
explanation of carcinogenicity: thorium oxide compounds are required by
osha to be considered carcinogenic.
effects of overexposure: headache, dizziness, nausea, irritation of
eyes, nose and throat and burns if protective measures are not
observed.
medical cond aggravated by exposure: none specifically known.
First aid: eye contact-if irritation occurs, flush with large amounts of
water for 15 min, if irritation persists, seek medical attention.
skin contact-wash with soap & water, isolate from exposure if rash
occur s. Seek medical attention if rash persists. Inhalation-if
large amounts of dusts are inhaled, move exposed person to fresh
air. If necessary perform artificial respiration & seek medical
attention. In gestion-seek medical attention. Give large quantities
of water & induce vomiting. Do not make an unconscious person
vomit. Other-wounds should be cleaned thoroughly asap.
