iSi specializes in composite dust assessments, solvent and chemical vapor monitoring, and aerospace manufacturing hazard evaluations for Boeing suppliers and operations throughout the Puget Sound region. We assess exposure risks specific to composite materials, adhesives, and surface treatments used in aerospace manufacturing, and deliver fixed-price industrial hygiene reports that support procurement and compliance requirements.
How does iSi help with environmental compliance for maritime and port operations in Seattle?
Port operations in Seattle face strict Washington Department of Ecology regulations on water discharge, air emissions, and hazardous material handling. iSi provides water discharge compliance consulting, stormwater management audits, and air permit support tailored to maritime operations. We also assess environmental risks from cargo handling, fuel storage, and vessel maintenance activities.
