Foxconn has taken further action to ensure the safety of its workers after a blast killed three employees and injured many more last week.
The Wall Street Journal reports that the company, which is known officially as Hon Hai Precision Industry, has closed all of its workshops that handle polishing for electronic parts and products pending further inspections.
The plant where the blast occurred, in Chengdu, China, is relatively new and is one of several that the company owns across the country.
The Chengdu plant reportedly manufactured the iPad and iPad 2, though neither Apple or Foxconn have confirmed this. There are conflicting reports as to whether iPad supplies will be affected by the blast and subsequent stoppage.
Foxconn also makes parts for HP and Motorola, and a recent report criticising working conditions in the Chengdu plant has come to light since the explosion.
The report, from the watchdog group Students & Scholars Against Corporate Misbehavior (SACOM) said: "In the milling machine department in Chengdu, some workers state they always breathe in the aluminum dust. Workers in the polishing department also complain that the department is full of aluminum dust. Some workers comment that ventilation on shop floor should be improved."
Another Foxconn plant in Shenzhen came under scrutiny last year after a spate of worker suicides.
