The Wall Street Journal reported that Hon Hai spokesman Louis Woo said that company has made improvements in its workshops to address buildup of aluminum dust in the air vents. This dust is believed to have ignited and caused the explosion.

Woo did not elaborate on what improvements had been made but told the Journal that the plant has reviewed the areas where the dust is created as a by-product and that the new measures “are a direct response to our efforts to ensure that we are applying the highest possible safety practices.”
