e Highest reading in the training simulation room: 65.7 dBA
e Peak level recorded: 89.3 dBC
Data-logged measurement (7:34 AM - 4:12 PM; 8h 38m):
e Projected 10-hour TWA: 57.6 dBA
e Maximum recorded peak: 86.7 dBC
5.2. Acrose Conclusion
e Noise levels are well below the occupational exposure limits of

o 85 dBA (Lex, 8-hour TWA)
o 140 dBC peak limit

e Overall risk of noise overexposure is low.

Investigation Analysis

After reviewing:

e Worker statements
e Internal RSS measurements
e Acrose Consulting’s professional findings

e 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.
