- Wash hands and inspect plugs before insertion;
- Wash reusable plugs daily and store in a clean case;
- Replace plugs that are hard or discolored as soon as possible;
- Make sure the plug fits properly inside the ear canal. If done correctly, the wearer’s voice will sound louder to him/her; and
- With headband plugs, do not bend or twist the band.
- Check cushions with each use and wash them as needed; and
- Ensure that there is a tight fit as loose muffs will not reduce the noise.
