CSB Extends Deadline for Comments on Combustible Dust

November 26, 2018

The U.S. Chemical Safety and Hazard Investigation Board has extended the deadline for its “Call to Action: Combustible Dust” initiative from Nov. 26 to Dec. 31, allowing the public more time to submit comments on combustible dust-related issues. 

The agency seeks to gather information on safe conduct of work in dust-producing environments that are at risk of dust explosion incidents, including methods of recognizing and measuring “unsafe” levels of dust, how stakeholders communicate about the hazards, and ways to maintain dust collection systems, Powder & Bulk Solids reported in late October. 

CSB officials initiated the effort as part of its investigation into the May 2017 explosion at a Didion Milling facility in Wisconsin.

“While there is a shared understanding of the hazards of dust, our investigations have found that efforts to manage those hazards have often failed to prevent a catastrophic explosion,” Kristen Kulinowski, interim executive of the CSB, said in the initial announcement of the Call to Action. “To uncover why that is, we are initiating this Call to Action to gather insights and feedback from those most directly involved with combustible dust hazards.”

Agency officials have issued four recommendations for the creation of a combustible dust-related general industry standard through the U.S. Department of Labor’s Occupational Safety and Health Administration (OSHA). The issue is listed in the CSB’s Drivers of Critical Chemical Safety Change list. 

Those wishing to take part in the CSB’s effort have until Dec. 31, 2018 to email their comments to [email protected]
