Washington’s Division of Occupational Safety and Health (DOSH) is moving to make changes to its excavation, trenching, and shoring standard, and they want to hear from employers. On February 10-12, 2026, Washington’s State Department of Labor & Industries will hold public hearings on DOSH’s proposal to amend Chapter 296-155-655 WAC, Part N, the Evacuation, Trenching, and Shoring safety standards.
