Subject: FORMAL NOTICE: Staged Test Environment & Active Suppression of Evidence — Claim
842647461

ATTENTION: WarkSafeBC Case Management and Arcose Consulting Group,

1am variting to formally notify all parties that Report ID: 2044-20260206 (Project No. 2044.20383.2026) is
fundamentally flawed, based on a staged test environment, and reflects a deliberate suppression of forensic
data.

AS a 25-year heavy industry professional with an honors-level technical background {3.73 GPA, NAIT), iam
submitting the following Evidence of Administrative and Regulatory Non-Compliance:

1. ACTIVE SUPPRESSION OF THE JAN 29 FORENSIC BRIEF The attached Acoustic Trauma Brief was filed
on January 29, 2026, as part of my formal WorkSafeBC Unsafe Workplace Report: WorkSafeBC and the
Employer failed to provide this brief to the Arcose investigators. By withholding this forensic data, the Board
ensured the survey would ignore the documented 328Hz narrow-band resonance ("Acoustic Laser"} that
caused my injury.

2. THE REGULATORY "HARD STOP": UNPERMITTED INSTALLATION This is an Industrial-scale Server
deployment in a Classroam/Office envirenment—not a machine shop. A forensic audit of 317 municipal
records confirms this equipment was installed without bermits, violating NFPA 75/76 standards. This site is
currently under active investigation by the City of Bumaby Building Permit Supervisor. Labeling an illegal,
unpermitted fire hazard as "safe" is a breach of professional and regulalory duty.

3. THE CONFIGURATION “CATCH-22" (STAGED ASSEMBLY) My acule acoustic trauma on January 25
occurred because the equipment was Operated in a broken state with a missing side panel, allawing raw
mechanical noise to reflect off the window directly into my left ear. This report is now trapped in a forensic "Caich-
22":

+ SCENARIO A (Tested with panels ON): The employer presented a staged environment. A "sealed"
machine does not represent the unshielded state that injured me.

+ SCENARIO B (Tested with panels OFF): You have professionally certified an unshielded, broken, and
unpermitted machine as "safe" for a classroom environment.

4. MISREPRESENTATION OF CLINICAL TRAUMA The employer and the Board have framed an acute physical
injury as a “subjective distraction." They have withheld the clinical teality: 5 Emergency Room visits, a
documented 10dB asymmetric hearing drop, and clinical Tonic Tensor Tympani Syndrome (FTTS). Relying
on A-weighted averages to "smooth over" a localized trauma is scientifically dishonest,

NOTICE OF LIABILITY: WorkSafeBC is currently using a report based on a staged environment to deny
medical care and wages to an injured worker. Now that all parties have been formaily provided with the actual
operational state (missing panel), the clinical outcome {acute trauma), and the regulatory reality (City of
Burnaby investigation). ! axpect an immediate review of this claim and an expedited specialist referral.
Sincerely,

Mark Holand
