Reducing Chemical Risk

Reducing chemical risk continues to be a focus at Weyerhaeuser. We have updated our chemical management standard, setting clear expectations for "no new purchases" of products containing polychlorinated biphenyls, asbestos or lead-based paints and "restricted use only" of products containing chlorinated solvents, mercury compounds or aerosol propellants.

In 2006, we continued our focus on reducing the overall number of chemical products used through improved inventory management and on improving the accuracy of our chemical product inventory by eliminating outdated records. These efforts reduce the risk of chemical exposures and improve employee access to chemical product information through Material Safety Data Sheets.

In our wood products organization, businesswide goals for chemical management have driven a dramatic chemical reduction improvement. That business has reduced the total number of chemicals in our MSDS database by more than 65 percent between 2004 and 2006. Our goal is to reduce the total number of chemicals purchased by using the same set of approved products across multiple sites. In our wood products business, we have improved the number of products used at a single location from 43 percent to less than 20 percent between 2004 and 2006.

Companywide, we continue to focus on reducing chemical risk, including:

• Reducing and eliminating the use of certain high-risk chemicals identified in our chemical management standard
• Continuing our chemical reduction efforts through improved inventory management of all chemical products and better MSDS management
• Seeking less hazardous substitutes for chemicals and using these across the company
