- Washington State Department of Ecology is seeking building industry workers, including construction workers, contractors, building inspectors, installers/finishers, and painters to participate in a Safer Building Materials Focus Group. This group will meet in early 2026 and be compensated with a $200 gift card for each selected participant. To indicate interest please complete this very brief survey. We will engage workers to hear their experiences using common building products such as paints, adhesives, caulks, and insulation. This effort is about learning directly from workers- those who know best about the products they use every day.
- Focus group questions may include:
- What products do you use most often?
- What, if any alternative products have you considered using?
- How do you usually learn about the chemicals in these products?
