BANDED EAR PLUGS
INSTRUCTIONS FOR USE
Read all safety warnings, instructions, illustrations, and specifications
provided. Save all warnings and instructions for future reference.
Failure to follow these instructions can result in hearing loss or injury.
These earplugs can help reduce exposure to hazardous noise and loud sounds.
Misuse, improper fit, or failure to wear hearing protectors during all
exposure may result in hearing loss or injury.
If you experience ringing or buzzing in your ears, or your hearing seems
dulled, your hearing may be at risk. Consult a physician if you suspect
hearing loss. Consult with a physician before wearing hearing protection if
you have drainage from your ears or an ear infection.
Only use these earplugs if a good fit can be obtained. If not, use another
type of hearing protection.
CHOKING HAZARD-Small parts. Keep away from infants and small children. **
This hearing protection must be worn properly, with
ear tips attached to the band, to help provide effective protection. Do not
wear ear tips or band alone. The band may be worn in several positions,
including under the chin, overhead, and behind the neck.
Wash hands before use. Ear tips should be clean before fitting**
-
Position band in the desired wearing position.
-
While pulling the ear outward and upward with the opposite hand, hold the end of the band and insert the ear tip into the ear canal. Adjust for best noise reduction.
-
Check fit: When this device is well-fitted, your voice should sound louder, deeper, and hollow when you talk.
CAUTION: For greater control and safety, remove the ear tip slowly with a twisting motion to gradually break the seal.
-
Wash ear tips with mild soap and warm water as needed. Look for tears or cracks under any of the three flanges.
-
Replace if the band is damaged or no longer holds ear tips firmly in place when worn, if ear tips are damaged or if ear tips are not soft and pliable. Push and twist new ear tips onto the band until ear tips snap into place.
If you cannot obtain a good fit, try a different type of hearing protection.
WARNING! Rapid removal may damage the eardrum.
The level of noise entering a person’s ear, when a hearing protector is worn
as directed, is closely approximated by the difference between the A-weighted
environmental noise level and the NRR.
Example:
- The environmental noise level as measured at the ear is 92 dBA.
- The NRR is 25 decibels (dB).
- The level of noise entering the ear is approximately equal to 67 dBA.
For noise environments dominated by frequencies below 500 Hz, the C-weighted
environmental noise level should be used.
Improper fit or inconsistent use of this device will reduce its effectiveness
in attenuating noise. Consult the enclosed instructions for proper fit.
Although hearing protectors can be recommended for protection against the
harmful effects of impulsive noise, the noise reduction rating (NRR) is based
on the attenuation of continuous noise and may not be an accurate indicator of
the protection attainable against impulsive noise such as gunfire.
For example, gunfire exposure depends on the weapon type, the number of rounds
fired, proper selection, fit and use of earplugs, proper care of hearing
protection, etc.
The US EPA specifies the NRR as the measure of hearing protector noise
reduction. However, MILWAUKEE makes no warranties as to the suitability of the
NRR for this purpose. Research suggests that many users will receive less
noise reduction than indicated by the NRR due to variation in earplug fit,
earplug fitting skill, and motivation of the user. It is recommended that the
NRR be reduced by 50% to better estimate typical workplace protection
