Caution
Inserting or removing earplugs too quickly might result in air pressure
or suction against the eardrum, causing temporary pain. Earplugs
should be inserted or removed slowly with a twisting motion to prevent
excess pressure buildup. Gently moving the earplug while opening the
jaw fully might remove excess pressure buildup.
Prolonged use of earplugs (exceeding several hours) might result
in temporary soreness near the ear canal. Use of earplugs might
reduce the risk of this irritation when compared to expandable foam
type plugs. The use of ear plugs might require a "break-in" period to
accustom the ear canal to the presence of the earplug.
In order to ensure maximum performance, the ear canal should be
clean and free of excess ear wax and debris before inserting earplugs.
Long term usage of earplugs could result in the buildup of ear wax
within the ear. In the event that ear wax or debris becomes impacted in
the ear canal, seek medical consultation.
When not in use, store earplugs in original container. Surfaces that
have been dyed should be avoided to prevent the possibility of having
the dye transfer onto the earplugs. Plug surfaces should remain clean
and free of other contaminates that could cause irritation of the ear
canal such as sand and grit.
Earplugs should be cleaned periodically in warm, soapy water to
prevent buildup of dirt and bacteria. Ear inflammation, otitis externa, or
other infection could result from the use of dirty ear plugs. In the event
of pain or discharge from the ear canal, seek medical consultation.
Earplugs are made from an immunologically inert material and allergic
reactions are rare. In the event an allergic reaction is suspected,
discontinue use and seek medical consultation.
