ATTENTION! An Upgraded Version of the Site to Launch in January 2026 – Act now to download any saved plans.

CPWR launched this site in 2012, and we are pleased to report it continues to be used regularly to protect workers from silica exposure. To ensure the site continues working long-term, we are in the process of upgrading the underlying technology. If you are a registered user, there is a chance that saved plans in your account may be lost during the transition. If there are plans you want to keep, please save them to your computer by selecting the “Print” option and then printing or saving the documents as PDF files (the “Download” function is currently unavailable) by December 31, 2025.

We apologize for the inconvenience but appreciate your support during this upgrade.

Regulations & Requirements

OSHA Construction Standard

On March 24, 2016, OSHA issued a final silica standard for the construction industry. The new standard went into effect on June 23, 2016, and OSHA began enforcement on September 23, 2017. 

Challenges to the standard were dismissed by the United States Court of Appeals for the District of Columbia Circuit in December 2017.

To learn more about the new construction standard, view the on-demand webinar "Understanding & Implementing the New Construction Silica Standard" presented by: David O’Connor, OSHA's Directorate of Standards & Guidance, Chris Trahan, CPWR Deputy Director, and Eileen Betit, CPWR r2p Director. This webinar reviewed the key provisions in the new standard and how CPWR's free planning tool can help contractors comply.
