Common Mistakes When Using Hearing Protection Stats and Facts

FACTS

  1. Improper insertion of earplugs or loose earmuffs can reduce their effectiveness, exposing users to harmful noise.
  2. Removing hearing protection, even briefly in loud environments, allows cumulative hearing damage to occur.
  3. Using hearing protection with the wrong noise reduction rating (NRR) can either block necessary sounds (e.g., alarms) or fail to prevent hearing loss.
  4. Damaged or old earplugs and earmuff cushions don’t seal properly, diminishing protection.
  5. Reusing dirty or improperly stored hearing protection can cause ear infections or discomfort.
  6. Workers unaware of correct usage techniques may misuse hearing protection, reducing its benefit.
