All Day - Registration opens 7:30am

Free RSVP at https://www.eventbrite.com/e/preventing-silicosis-tickets-856476021837  The purpose of this conference is to bring together affected workers, employers and manufacturers with researchers, unions, community-based organizations and other stakeholders to develop practical and feasible solutions to prevent silicosis caused by artificial stone.  Key Questions:  
  1. What factors are driving the current epidemic of silicosis among artificial stone workers?  
  1. What are the needs of affected workers, employers, and silicosis patients?  
  1. What research gaps exist?  
  1. What interventions are available to protect workers and prevent new silicosis cases?  
Desired Outcomes: Develop a research agenda and a concrete set of recommendations that could be implemented in the California context and shared with other impacted communities.
