An indoor facilities checklist never mentions runoff from a vehicle wash bay that drains toward a storm ditch. What source category is missing?
Select an answer to reveal the explanation.
Short Explanation
If soapy water runs to a ditch, the hazard left the building even if your checklist stayed indoors. Environmental pathways are risk sources too. Follow the drain, not just the mop closet.
Full Explanation
Environmental sources include discharges and pathways that can harm ecosystems, neighbors, or regulatory standing. Wash-bay runoff toward storm systems is a classic environmental identification item. Indoor-only checklists miss pathways that leave the building envelope.
