China issues combustible dust explosion guidelines
18 September 2015
China has released its first national guidelines on preventing combustible dust explosions in workplaces, Xinhua said on September 11. The guidelines, issued by the State Administration of Work Safety, listed requirements for work sites where combustible dust is present, technical anti-explosion measures and dust removal requirements.
The guidelines stem from investigations into two recent dust explosion incidents which caused multiple casualties and are aimed at preventing similar cases, according to an official within the administration.
A blast on August 2 last year gutted a wheel hub polishing workshop in Kunshan, in eastern China's Jiangsu Province, leaving 146 dead and hundreds injured. The subsequent investigation found that the explosion was caused by the ignition of metal dust in the workshop, which had been allowed to build up to excessive levels.
And on June 27 this year, coloured powder blown from the stage during a party at a water park in Taiwan ignited, causing a fireball to engulf the audience. As of September 2, 12 had died from injuries sustained in the blast and 508 were listed injured, with 199 in a critical condition.
