Slick new technology cleaning up oil work

Thanks to improved conditions and tidier workplaces, the phrase "getting one's hands dirty" is becoming a relic of the past for more and more laborers in China.

Li Sijiu, a worker at a petrochemical facility in the Xinjiang Uygur autonomous region, is one such beneficiary of recently installed eco-friendly equipment and technologies.

"Our uniforms used to be stained with crude oil and wax after a day's work, and sometimes they could even stand up by themselves after being taken off due to their filthy stiffened conditions," Li said, adding that things are much better now.
