Independent acoustic spectral analysis — 328Hz resonance identified and calibrated before any
remediation. Burnaby permit database researched and searched. NFPA 75/76 fire code
violations identified and documented. Building code violations identified and documented. All
self-directed. All accurate. All before any regulatory body acted.

This investigation was more thorough than the one conducted by BCRTC’s own Occupational
Health department. It was conducted by an injured worker, without institutional resources, while
managing five emergency room visits and a progressively worsening acoustic injury.

The Neurotypical Logic Failure — Why OHS Needs This Perspective

The January 27 dismissal demonstrates a critical gap in BCRTC’s safety culture. The OC health
officer measured dB level with a handheld meter — a broadband amplitude measurement.
Passed. Dismissed.

What was not measured: tonal quality, frequency-specific resonance, continuous vs intermittent
exposure, individual sensory susceptibility, room mode amplification, or glass reflection
geometry. The wrong too! was used to measure the wrong thing and the result was treated as
definitive.

Mark is an undiagnosed autistic worker with hi-fidelity hearing and a 25-year history of careful
hearing protection. His nervous system processes sustained tonal resonance differently than a
neurotypical worker. The 85dB threshold was never designed for this presentation.

An OHS professional with this lived experience and this understanding is able to ask the right
questions when a worker reports a noise concern — not just reach for a dosimeter. That
capability does not exist in BCRTC’s current OHS department. It is the gap that caused this
injury.

Technical Skills

Data analysis. Python. PowerShell. Audacity. FFmpeg. Raspberry Pi. Arduino. Network
analysis. Wireshark. RTSP. Database research. Report writing. Evidence documentation.
Multi-agency complaint filing. Home sleep laboratory design and operation. All developed or
applied directly in the context of this workplace safety investigation.

CozZie Glow — a self-built forensic sleep monitoring system — produced the sleep study
footage submitted to WorkSafeBC. Total project cost: $7. Built from a parts inventory and a
Raspberry Pi. The same investigative instinct that found the broken rail built a sleep laboratory
in a tent to document what the medical system was too slow to investigate.

Safety Culture — The Missing Piece

BCRTC has safety paperwork. What it needs is a safety culture.

CN Rail had a safety culture. Proactive. Trend-based. Solution-oriented. Leadership treated
near misses as seriously as injuries. Workers reported hazards without fear of dismissal. When
train and hi-rail vehicle collisions were increasing, new mandatory radio callout procedures were
introduced — verbal confirmation on both train channel and maintenance channel before
entering track.

The procedure worked. Collisions dropped. But not simply because of the communication. The
callout procedure worked because it forced a mandatory cognitive checkpoint at exactly the
right moment. To make the call, you had to locate yourself precisely on the subdivision, identify
your conflicting movements, recite your authority limits from memory, and confirm your
boundaries out loud before your hi-rail wheels touched the rail. You could not complete the
