We heard news last week that an iPad back-panel supplier had an explosion that injured 61 people in the Shanghai factory. Now the China Labor Watch, and other labor organizations, are investigating factories in China.
The factory explosion from last week is believed to have been caused by the aluminum dust that comes form polishing and carving the back panels of the iPad. Reports (via 9to5Mac) also mention a similar explosion in a Foxconn factory in Chengdu which killed three workers and injured 15.
It’s said that workers were not aware of the potential danger before the accident. However, the report goes onto say the U.S. Occupational Health and Safety Administration says aluminum dust is highly combustible and extra precaution needs to be taken when handling the material.
