According to the Taipei Veterans General

are engineers, cases were reported almost
every domestic semiconductor factory.
ROC Emergency and Critical Care Medicine yesterday held a
Symposium, Taipei Veterans General Hospital

erosion, cleaning, marking silicon, almost
half of the semiconductor manufacturing

skin is exposed to inhaled or ingested, will
produce severe hypocalcemia and

Even more frightening is that if accidental
contact, early may not have obvious
symptoms, a few hours after will feel pain.
There have been the engineers only half arm
was spilled, but two hours after cardiac

Weifeng remind addition to semiconductor staff, cleaning
companies, window washing workers,
