HEARING PROTECTION
Clean your earplugs after every use. When needed, wipe clean
with a damp cloth. Only wash earplugs after you have removed
filters. Do not clean with harsh chemicals. Alcohol is not
recommended.
Store your earplugs in their protective case after every use. Do not
store anything else in your earplug case.
TIPS & WARNINGS
• Your earplugs comply with EN-352-2 and ANSI S 3.19
standards of measurement.
• To achieve the ideal hearing protection and attenua-
tion, your earplug must be properly fitted, adjusted,
and maintained. It must seal the ear completely. If
unsure of size, start with the larger earplug.
• When exposed to potentially dangerous noise levels,
use your earplugs continuously.
• Make sure your earplugs provide adequate protection
for the noise level in your environment.
• To assure ongoing serviceability, regularly inspect your
earplugs.
• Never remove filter while using your earplugs.

chemical substances. Do not clean with harsh chemicals
