The FOl-released source document reveals this data was collected on March 22, 1991 — 35 years before the worker's injury. A 1991 BC Ferry vessel data centre is a restricted, industrial, access-controlled machine room aboard a marine passenger vessel. Personnel enter for maintenance. It has no acoustic, spatial, or contextual relationship to a 2026 classroom where human beings sit within arm's reach of uncased industrial server hardware for 10 hours a day. The thermal, acoustic, and structural profiles of a marine hull and a metropolitan training room are categorically incomparable. The low-frequency structural thrum of a marine diesel vessel is acoustically unrelated to the high-frequency electromagnetic whine of modern server cooling arrays.
