When can earmuffs be worn?

Earmuffs are designed to provide hearing protection and are appropriate for use in various environments where noise may pose a risk to hearing health. They are typically worn over the ears to minimize exposure to loud sounds. The correct response indicates that earmuffs can be worn only in conjunction with outer garments.

This guideline is likely rooted in safety protocols that require personal protective equipment (PPE) to be worn in specific settings, ensuring that individuals are adequately protected from noise and other environmental hazards. Wearing earmuffs with an outer garment emphasizes the importance of complete PPE usage, promoting both safety and compliance with workplace regulations.

While other options imply limitations or specific conditions for wearing earmuffs, the correct choice aligns with the overarching principle of maintaining safety standards in environments where noise levels may exceed permissible limits and where additional protective clothing may enhance overall safety and regulation adherence.
