Daily exposure to hexyl hydrid can cause long-term and possibly irreversible nerve damage, said Lam Ching-wan, a chemical pathologist at the University of Hong Kong. According to U.S. National Library of Medicine, there have been dozens of documented cases where workers suffered nerve and eye damage from exposure to n-hexane.
Workers said they wore protective gear, including masks and goggles, but worked in an enclosed, poorly ventilated space. In its report, Apple said that Wintek had switched to the chemical from alcohol without changing the ventilation system.
Jia, the technician, said that after working for a year on the production for Apple touch screens, he felt there was something wrong, but ignored the problems, blaming them on work stress or moodiness.
Soon he heard other workers were hospitalised and suspected it had something to do with the chemical hexyl hydride, which managers had said could be safely used.
Jia went to a hospital in Suzhou in August 2009, when doctors told him he had nerve damage. Doctors soon found many of his workmates had similar problems and were advised to be hospitalised.
