From Eur Ing Keith Plumb | Pulse | LinkedIn Corn Silo Topping - Junkin Media Dust Explosions – Sources of Dispersion and Ignition Not Independent Published on August 18, 2017 Eur Ing Keith Plumb Process and Equipment Consultant In the November 2015 issue of the Chemical Engineer I wrote an article ( https://www.integpharma.com/white-papers ) about the fatal flaws associated Hazardous Area Classification. In this article I wrote the following with respect to equipment selection. “Also, the logic behind this selection is that the event that  causes a dust cloud to form is independent of the event that leads to an ignition source becoming active. This is probably true for electrical equipment, less so for non-electrical equipment and could be completely  wrong for an electrostatic spark where the creation of the dust cloud  could also create the spark.” The video at the link below shows a corn silo at White Farms Inc in Indiana, USA, topplin...

Dust Explosions In The Food Industry Wed, 03/21/2012 - 1:43pm Vahid Ebadat, Ph.D., CEO, Chilworth North America  From Manufacturing.net, an article by Dr. Vahid Ebadat, CEO Chilworth. This feature originally ran in the  March 2012 issue  of  Food Manufacturing , a Manufacturing.net sister publication . A food processor's guide to understanding how dust explosions happen and what can be done to prevent them. The vast majority of powders in the food industry can form explosible dust clouds if the particle size is small and moisture content is low. Although explosible dust cloud concentrations are not normally expected to be present within processing buildings, explosible dust clouds are regularly formed inside material handling or processing equipment when bins are being filled, powders are being transferred or dust is being collected in a dust collector. The particle size of the dust is a property which influences the explosi...

Five explosions preceded deadly incidents in Burns Lake, Prince George

One B.C. pellet mill blast went unreported From The Vancouver Sun: Five explosions preceded deadly incidents in Burns Lake, Prince George Read more: http://www.vancouversun.com/news/sawmill+blast+went+unreported/6550344/story.html#ixzz1uNfhMnMq A wood dust explosion 16 months ago that blew apart a small control room and started a fire at a Williams Lake sawmill went unreported to WorkSafeBC, the chief workplace safety agency in the province. The incident was among five explosions news reports linked to wood dust in north and central B.C. between 2009 and 2011 that took place before two fatal sawmill explosions this year at Babine Forest Products in Burns Lake and Lakeland Mills in Prince George. WorkSafeBC also said it has no record of an explosion in 2011 at a Pinnacle Pellet plant in Armstrong. WorkSafe inspectors and industry representatives have not directly linked the two fatal sawmill explosions, which killed four workers and injured dozens more, to w...

International combustible dust expert talks minimising the risk of dust explosions « Informa Australia

International combustible dust expert talks minimising the risk of dust explosions « Informa Australia Our friend John Astad of the Combustible Dust Policy Institute is a featured speaker at Informa Australia Dust Explosions 2012 Conference:  Dust Explosions 2012 - The Dust Explosions Conference will examine the means to control dust and the latest technology to ensure the maximum safety of your organization.    Informa Australia is pleased to welcome international combustible dust expert Mr John Astad  to the speaking faculty of Dust Explosions 2012 . Based in the USA, Mr Astad is the Director and Research Analyst for the Combustible Dust Policy Institute which aims to minimise the severity and reduce the occurrence of combustible dust related fires and explosions in the workplace through ongoing research of combustible dust related incidents.   We had the opportunity to talk to John before he heads our way next month. The risk of complac...
