Which precaution should an instructor follow to protect students from training ground noise?

Using earmuffs or earplugs in environments with noise levels exceeding 90 decibels is a fundamental safety measure for protecting students from potential hearing damage during training. In high-noise environments, such as those commonly found in fire rescue training scenarios, prolonged exposure to loud sounds can lead to various levels of hearing loss. By providing hearing protection like earmuffs or earplugs, the instructor helps to ensure that students can focus on the training exercises without being distracted or put at risk by the surrounding noise. This practice not only aligns with safety standards related to occupational noise exposure but also promotes a conducive learning environment where students can hear instructions clearly and participate without the risk of auditory harm.
