Feds issues video on dust danger
Volume 24, No. 5
The U.S. Chemical Safety Board (CSB) released a new safety video in July depicting how accumulations of combustible dust at worksites can provide the fuel for devastating explosions that kill and maim workers, shut down plants and harm local economies.
Entitled "Combustible Dust: An Insidious Hazard," the new video is available online at www.CSB.gov and on YouTube. It can also be ordered free of charge on a new two-DVD set of all CSB safety videos by filling out the CSB's online request form.
"Combustible Dust" features all-new CSB computer animations which illustrate three major dust explosion accidents the CSB has investigated in Kinston, NC; Corbin, KY; and Huntington, IN.
For each accident, the animations show how explosive dust accumulated over years on plant equipment, pipes, floors, ducts, dust collectors and other areas. The video shows how conditions develop needing only an ignition source to set off a primary explosion, which lofts the accumulated dust, leading to secondary explosions.
News footage and still photographs depict actual damage caused by these explosions, as well as other accidents including last year's tragedy which killed 14 workers at a sugar refinery in Port Wentworth, GA.
Laboratory footage in the video depicts how easily combustible dust ignites, as a small dust sample gathered by investigators in the rubble of a dust explosion site is lofted over a flame and creates an instant fireball
