What is the best way to ensure earplugs or earmuffs are worn correctly?

• A. Perform a fit check before use
• B. Follow the manufacturer’s instructions
• C. All of the above
• D. Ignore discomfort

Answer: (C)

Protection works only when it seals properly. A fit check before use confirms earplugs or earmuffs actually seal and provide the intended noise reduction. At the same time, following the manufacturer’s instructions ensures you use the device as designed—correct insertion or placement, proper adjustment, and maintenance. Together these steps guarantee the protectors are worn correctly and maintain their effectiveness. Don’t ignore discomfort; if anything feels off, re-fit, adjust, or replace the equipment, as a poor fit can defeat the attenuation and leave you exposed.
