In terms of PPE, which item is essential for protecting workers' hearing?

The essential item for protecting workers' hearing is earplugs or earmuffs. These are specifically designed to reduce the impact of loud noises on the ear, which is crucial in environments where noise levels can cause hearing damage or loss. Hearing protection is a vital aspect of personal protective equipment (PPE) since prolonged exposure to high-decibel sounds can lead to irreversible hearing impairment.

While safety goggles protect the eyes, reflective vests enhance visibility, and hard hats safeguard the head from falling objects, they do not address hearing protection directly. Therefore, earplugs or earmuffs are the designated gear to help ensure that workers' hearing remains safe in high-noise environments.
