Seattle's workplaces run from downtown and South Lake Union tech towers to Boeing-era aerospace and manufacturing plants, waterfront maritime and port facilities, and offices perched on steep hills. The tech towers, large plants, and pier facilities each demand different egress thinking, and the terrain itself complicates where people can safely gather.
Washington runs its own program: WISHA standards administered by L&I's Division of Occupational Safety and Health (DOSH), often stricter than federal OSHA, require an emergency action plan with marked exit routes and assembly areas. The Seattle Fire Department enforces local fire codes on top of that.
The defining regional risk is the Cascadia subduction zone, which threatens a major earthquake and, for waterfront sites, tsunami inundation. OSHAMap reads your floor plan and lays down exits, routes, and assembly points for you, turning a South Lake Union office or a waterfront facility into a posting-ready diagram in minutes.
