China on Thursday released the first national guidelines on preventing explosion of combustible dust in work places.
The guidelines, issued by the State Administration of Work Safety, listed requirements on safety management of work sites with combustible dust, technical anti-explosion measures, dust removal technology and other key security requirements on equipment and facilities.
The guidelines resulted from bitter lessons learned from two deadly explosions, and are aimed at preventing similar cases, according to an official with the administration. A factory blast on Aug. 2, 2014 gutted a wheel hub polishing workshop in Kunshan, east China's Jiangsu Province and left 146 dead.
Later investigation found that the explosion followed the ignition of excessive metal dust in the workshop. On June 27 this year, a fire broke out at a water park in Taiwan as the park was staging a party that saw a large amount of theatrical colored powder ejected from a stage.
The powder caught fire before landing on the audience. Nearly 500 people were injured in the blaze. One died in hospital. The guidelines asked businesses to take precautions and improve their rules and regulations on protection against dust explosion.
