Portland’s mix of working waterfront businesses, downtown construction, and older housing stock can create multiple pathways for exposure. In practice, that means the “who, what, and when” can be contested—especially when:
- The exposure involved a subcontractor or a maintenance vendor.
- The incident happened during a renovation, demolition, or cleanup of a commercial property.
- Safety information was stored on-site or in contractor systems that aren’t automatically shared.
- The chemical wasn’t obvious at the time (missing labels, outdated SDS sheets, or unlabeled containers).
Because of that, we work early to secure incident records, product and safety documents, and medical timelines that connect the exposure to your symptoms.
