The Apple manufacturing plant that exploded killing three people and seriously injuring at least 15 is back in business today, according to reports coming out of China.

The Wall Street Journal reports that Foxconn's parent company Hon Hai Precision has announced that its polishing workshops, which were the scene of the deadly explosion, resumed working this week, presumably after a bit of a clean-up.

Although neither Hon Hai nor Apple have offered details of how the explosion occurred, most have assumed that clouds of friable dust were somehow ignited causing the blast.

Considering that most electronics assembly plants have practically sterile conditions, we have to admit that we find that theory less than credible.

Fears that the production of Apple's recently-released iPad 2 would be delayed by the tragedy were allayed when production was shipped to one of the giant company's alternative plants.

Despite Apple being the only company ever mentioned whenever anything horrible happens at one of Foxconn's labour-intensive facilities, the company also makes products for Acer, Amazon, Asus, Intel, Cisco, HP, Del Nintendo, Nokia, Microsoft, Sony and Vizio.

The company has been plagued by accusations of running a sweatshop and has seen several workers commit suicide by flinging themselves from high windows in the recent past.
