CONCLUSION

The Arcose noise survey is not a valid clinical assessment of my occupational exposure. It was
conducted under conditions that do not represent the conditions of my injury, without the clinical
documentation that would have changed its scope, using a fraction of the instrument's available
capability, by consultants who were not provided the clinical context necessary to select the
appropriate methodology, and without addressing the specific concerns | raised in writing six
weeks before the survey was conducted.

BCRTC had written, timestamped knowledge of my injury, my symptoms, my technical
concerns, and my requests for escalation from January 22 onward. That knowledge was not
communicated to Arcose. The report Arcose produced reflects the incomplete brief they were
given — not the complete clinical picture of what happened to me at Workstation 3.

| am requesting that the medical advisor reviewing this claim receive this submission alongside
the Arcose report — not the Arcose report in isolation. The evidence is clear. The timeline is
documented from day one. | followed every correct process available to me. This injury is real, it
is documented, and it was preventable.

Sincerely,

Mark Holand
