Wei Chaihua, 44, is dying from silicosis as a result of making parts for Char-Broil gas stoves. Here, he is given oxygen from a tank next to his bed at the Guangdong Hospital for Treatment and Prevention of Occupational Diseases. Chinese workers also get silicosis while making jewelry, tiles, countertops and tool and dye parts for U.S. export.
