  1. Reach over your head with a free hand, pull your ear up and back, and insert the earplug well inside your ear canal. 
  2. Stop pushing earplug when your finger touches your ear. 
  3. If properly fitted, the end of the earplugs should not be visible to someone looking at you from the front. 
  4. Proper Fit – If either or both earplugs do not seem to be fitted properly, remove the earplug and reinsert. 
  5. Removal – Gently twist earplug while slowly pulling in an outward motion for removal. 
  6. Acoustical Check – In a noisy environment, with earplugs inserted, cup your hands over your ears and release. Earplugs should block enough noise so that covering your ears with your hands should not result in a significant noise difference.



  • INSPECT – Inspect prior to fitting, examine your earplugs for dirt, damage or extreme hardness—discard immediately if compromised.
  • DISCARD – For proper hygiene, discard Single-Use earplugs after use.
  • HYGIENE  – To maintain hygiene standards, Single-Use earplugs should be discarded at the end of every shift.
