ACT I: THE PHYSICAL HAZARD AND BIOLOGICAL REALITY The Environment — An Engineering Failure Inside a Classroom On January 12, 2026, the worker was assigned to Workstation 3 inside the OMC1 Training Room at BCRTC—a classroom designed for human learning and Control Operator simulation training. What was not designed for human occupancy, and what the employer had installed without building permits, were two refrigerator-sized industrial server racks positioned less than two feet directly behind the worker's head. This distinction matters more than any other single fact in this file. A data centre is a restricted industrial environment. Personnel enter in controlled conditions for defined maintenance tasks. The OMC1 Training Room was an occupied classroom, attended daily for ten-hour shifts, where unprotected trainees sat within arm's reach of unenclosed industrial hardware. The acoustic side panel on the active rack enclosure was missing—a structural containment failure that transformed the server from a background noise source into an unshielded acoustic projector aimed directly at the occupied workspace. On January 22, 2026, the worker filed MyHSE Safety Concern #75625 identifying the hazard explicitly and requesting remediation. He disclosed his personal vulnerability to excessive noise at that time—before his worst symptoms began. The employer did not replace the panel. They told him the sound levels were below 85 dB, as if the threshold for bureaucratic compliance were the same as the threshold for biological harm in a specific individual with a specific nervous system. The server rack remained uncorrected. The exposure continued. The Physics — 328 Hz and the Glass Reflection On January 29, the worker conducted his own on-site acoustic investigation. Using a calibrated USB condenser microphone, Audacity, and reference tones at 440 Hz and 1000 Hz to verify measurement integrity, he captured the frequency profile of the OMC1 environment from three spatial positions: left ear (glass reflection path), right ear (direct rack exposure), and behind head (shielded). The data revealed a dominant mechanical resonance spike at 328 Hz—a frequency in the range known to stimulate tensor tympani muscle activation. More critically, a glass partition wall to the worker's left was acting as an acoustic mirror, reflecting the server's output back toward his left ear canal. The spatial differential between the three measurement positions was quantifiable and reproducible. This was not subjective noise sensitivity. This was documented, directional, reflected acoustic energy focused onto a specific location: the left ear of the person at Workstation 3. The 70 dB drop measured in the shielded position confirmed that the worker's skull was physically absorbing energy—the mechanical basis of the chronic bilateral headaches that preceded the ear pain by a full week. The data was submitted to WorkSafeBC in the Acoustic Trauma Brief on February 6, 2026. It was not referenced in the subsequent Clinical Opinion.
