Fitting Instructions for Disposable Earplugs
Before fitting any earplugs, make sure your hands are clean.
1. Hold the earplug between your thumb and
forefinger. Roll and compress the entire earplug to a small, crease-free cylinder. While still
rolling, use your other hand to reach over your
head and pull up and back on your outer ear.
This straightens the ear canal, making way for
a snug fit.
2. Insert the earplug and hold for 20 to 30 seconds. This allows the earplug to expand and
fill your ear canal.
3. Test the fit. In a noisy environment, and with
earplugs inserted, cup both hands over your
ears and release. You should not notice a significant difference in the noise level. If the
noise seems to lessen when your hands are
cupped over your ears, your earplugs are probably not fitted properly. Remove and refit fol4. Always remove earplugs slowly, twisting them
to break the seal. If you remove them too
quickly, you could damage your ear drum.
Foam earplugs are disposable and not intended for re-use.
