BEIJING - By the end of this year all vehicles carrying dangerous chemicals, fireworks or explosives for civil uses will be required to install satellite-positioning devices that can record their whereabouts, the State Administration of Work Safety (SAWS) has announced.

This was part of China's increased efforts in 2011 to use advanced safety technologies to reduce fatalities and injuries caused by workplace accidents, Luo Lin, head of SAWS, said on Thursday at its annual conference.

The new rule for vehicles will also be applied to all tourist charter buses and cross-county long-distance bus services.
