What hazard does the 'wear ear protection' sign address?

• A. Prolonged exposure to noise
• B. Chemical burns
• C. Eye injuries
• D. Sharp objects

Answer: (A)

Hearing protection is needed to guard against damage from loud sounds. In environments with machinery or noisy tools, prolonged or intense noise can harm the inner ear and cause permanent hearing loss or tinnitus, so wearing earmuffs or earplugs reduces the noise reaching the ear. That’s why this sign addresses noise hazards specifically. The other options relate to different dangers—chemical burns, eye injuries, or cuts from sharp objects—each requiring different protective equipment, not ear protection.
