What is a potential disadvantage of earplugs?

• A. They are more expensive
• B. They cause immediate fatigue
• C. They provide better protection
• D. Hand to ear contamination

Answer: (D)

Handling earplugs involves touching them, so there’s a real risk of transferring germs from the hands into the ear canal. If hands aren’t clean or earplugs are shared, bacteria or fungi can be introduced, increasing the chance of infection or irritation in the ear or surrounding skin. That hygiene issue is the main drawback of using earplugs. To reduce the risk, wash hands before inserting, avoid sharing earplugs, and clean or replace them according to manufacturer instructions.
