WARNING
This hearing protector helps reduce exposure to hazardous
noise and other loud sounds. Misuse or failure to wear
hearing protection at all times when exposed to hazardous
noise may result in hearing loss or injury. For proper use,
see supervisor, User Instructions or call 3M Technical
Services. If your hearing seems dulled or you hear a
ringing or buzzing during or after any noise exposure
(including gunfire), or for any other reason you suspect a
hearing problem, leave the noisy environment immediately
and consult a medical professional and/or your supervisor.
Failure to follow these instructions may result in
serious injury or death:
• To reduce the risks associated with igniting an
explosion, do not use this product in a potentially explosive
atmosphere.
Failure to follow these instructions may reduce the
protection provided by the earmuff and may result in
hearing loss:
a. Research suggests that users may receive less noise
reduction than indicated by the attenuation value(s) on the
packaging, due to variation in fit, fitting skill, and motivation
of the user. Refer to your applicable regulations for
guidance on how to adjust label values and estimate
attenuation. In addition, 3M strongly recommends fit testing
of hearing protectors.
b. Ensure the hearing protector is properly selected, fit,
adjusted, and maintained. Improper fit of this device will
reduce its effectiveness in attenuating noise. Consult the
enclosed instructions for proper fit.
c. Inspect the hearing protector before each use. If
damaged, select an undamaged hearing protector or avoid
the noisy environment.
d. When additional personal protective equipment is
necessary (e.g. safety glasses, respirators, etc.), select
flexible, low profile temples or straps to minimize
interference with the earmuff cushion. Remove all other
unnecessary articles (e.g. hair, hats, jewelry, headphones,
hygiene covers, etc.) that could interfere with the seal of
the earmuff cushion and reduce the protection of the
earmuff.
e. Do not bend or reshape the headband or neckband,
and ensure there is adequate force to hold the earmuffs
firmly in place.
f. Earmuffs, and in particular cushions, may deteriorate
with use and should be examined at frequent intervals for
cracking and leakage, for example. When used regularly,
replace the ear cushions and foam liners at least twice a
year to maintain consistent protection, hygiene, and
comfort.
g. If the requirements above are not adhered to, the
protection afforded by the earmuffs will be severely
impaired.
EN 352 Safety Statements:
• This product may be adversely affected by certain
chemical substances. Further information should be sought
from the manufacturer.
• These earmuffs are of large size range. Earmuffs
complying with EN 352-1 are of “medium size range” or
“small size range” or “large size range”. “Medium size
range” earmuffs will fit the majority of wearers. “Small size
range” or “large size range” earmuffs are designed to fit
wearers for whom “medium size range” earmuffs are not
suitable.
• These helmet mounted earmuffs are of “large size
range”. Helmet mounted earmuffs complying with EN
352-3 are of “medium size range” or “small size range” or
“large size range”. “Medium size range” helmet mounted
earmuffs are designed to fit the majority of wearers. “Small
size range” or “large size range” helmet mounted earmuffs
are designed to fit wearers for whom “medium size range”
helmet mounted earmuffs are not suitable.
NOTE
• When worn according to these User Instructions, this
hearing protector helps reduce exposure to both
continuous noises, such as industrial noises and noises
from vehicles and aircraft, as well as very loud impulse
noises, such as gunfire. It is difficult to predict the required
and/or actual hearing protection obtained during exposure
to impulse noises. For gunfire, the weapon type, number
of rounds fired, proper selection, fit and use of hearing
protection, proper care of hearing protection, and other
