Keep away from infants and small children. These earplugs are non-toxic, but may interfere with breathing if caught in windpipe, which could lead to serious injury or death.
For noise environments dominated by frequencies below 500 HZ, the C-weighted environmental noise level should be used. Improper fit of this device will reduce the effectiveness in attenuating noise. 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. Refer to directions for proper fit.
