In training environments where noise exceeds maximum levels, at what decibel level should hearing protection be provided?

Hearing protection should be provided when noise levels reach 90 decibels in the U.S. and 85 decibels in Canada. This standard is established based on research that indicates prolonged exposure to sound levels at or above these thresholds can lead to hearing damage.

In training environments, including fire rescue training, the likelihood of exposure to high noise levels is significant, especially when operating equipment or simulating emergency scenarios. Therefore, it is essential to implement safety measures, such as the use of hearing protection, to prevent long-term auditory issues.

The other options present lower decibel levels that do not align with established occupational safety standards for hearing protection, which prioritize maintaining a safe auditory environment for those who may be exposed to hazardous noise levels.
