Just as Wintek has scored the contract to make touchscreens for the white iPhone 5, Chinese workers at the Taiwanese company’s Suzhou plant have urged Apple to look into the slate of chemical poisonings at the plant which they said could still hurt their health.
The issue is hexyl hydride, a chemical used by Wintek between May 2008 and August 2009 instead of alcohol to speed up production of Apple touchscreens. In an open letter published in a local Chinese newspaper, workers referred to hexyl hydride as “a killer that strikes invisibly.”
Symptoms of hexyl hydride poisoning include sudden numbness in hands, swelling and pain in the feet, tiredness and faintness. Long-term exposure can lead to permanent nerve and eye damage. 137 Wintek workers had been hospitalized because of the poisonings.
