C8: NIOSH Special Topics Part 2 - Updates on Engineered Stone-Related Silicosis: Toxicology, Exposure Assessment, and Exposure Control

Ernest N. Morial New Orleans Convention Center 

Room: 291 

CM Credit Hours: 1 

Silicosis outbreaks among stone countertop workers have raised serious concerns worldwide, especially with the growing use of engineered stone that contains high levels of crystalline silica. This session will present recent NIOSH research on engineered stone-related silicosis. NIOSH biologists will discuss the pathophysiology of silicosis, detailing the unique physicochemical factors that make exposure to engineered stone exceptionally hazardous. This includes recent toxicological findings on the heightened reactivity of freshly fractured dust and how the complex matrix of silica, resins, and trace metals drives persistent pulmonary and systemic inflammation. NIOSH researchers will share how they identified and located stone countertop fabrication companies to help prevent respirable crystalline silica exposure among countertop fabrication workers. NIOSH engineers will share insights from field studies, address common misconceptions about engineering controls, and provide practical strategies to protect workers in the stone countertop industry.

Join us to learn the latest NIOSH research on understanding and reducing engineered stone-related silicosis in stone countertop fabrication and installation.

Upon completion, the participant will be able to:
• Discuss the physicochemical reasons that make engineered stone dust hazardous.
• Describe how researchers identify and locate stone countertop fabrication companies to prevent respirable crystalline silica exposure among countertop fabrication workers.
• Identify major factors contributing to respirable crystalline silica exposure in stone countertop fabrication and installation.
• Outline specific measures to reduce silica exposure using the hierarchy of controls.
