Improper fitting will reduce effectiveness and could result in hearing loss or injury. Remove ear plug slowly with twisting motion to gradually break the seal. Rapid removal may damage ear drum. Keep away from infants and small children. These ear plugs are nontoxic, but may interfere with breathing if caught in windpipe. This is a disposable earplug. We do not recommend that this plug be reused. For noise environments dominated by frequencies below 500Hz the C-weighted environmental noise level should be used. Improper fit 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. Constant or repetitive exposure to impulsive noise may lead to serious injury, temporary or permanent deafness. The noise reduction rating (NRR) calculated from the attenuation data is 30 dB. LEIGHT Plugs must be properly fitted to attenuate noise effectively. Refer to instructions.
