5.2. Acrose Conclusion
e Noise levels are well below the occupational exposure limits of

o 140 dBC peak limit

e Overall risk of noise overexposure is low.

6. Investigation Analysis

After reviewing:

Worker statements in MyHSE

Internal RSS measurements

Acrose Consulting’s professional findings

Training conditions and workstation layout

The investigation concluded:

1. Noise levels in the training room do not pose a hearing health hazard.
2. WorkSafeBC Noise Exposure Limits were not exceeded at any time.

3. Some localized noise from server equipment and communication speakers is present, but
not at harmful levels.

4. The exam environment may have been subjectively distracting for the worker, but objective
measurements do not indicate unsafe conditions.

5. BCRTC acknowledges opportunities to evaluate whether alternative exam spaces or
administrative supports could reduce distractions for trainees during assessment.

7. Corrective Actions Already Taken
e Internal and third-party noise measurements completed.
e Workstation layout and proximity to server racks reviewed.

e Preliminary assessment of exam room scheduling and alternative room assignment.
