Fitting Instructions: Improper fit of this device will reduce its effectiveness. Fit your earplugs before entering a hazardous noise area. Hands and earplugs should be clean before fitting. 1. Roll plug slowly with thumb and fingers (Figure A). Gradually increase pressure to compress plug to a very thin crease-free cylinder. 2. Insert compressed plug well into ear canal while pulling ear outward & upward with opposite hand (Figure B). 3. Check fit after plug expands in ear: Touch plug. You should feel only the end of plug (Figure C). If you feel most of the plug outside the ear canal (Figure D) remove plug & repeat fitting. Listen to steady loud noise with plugs in both ears. Cover ears with tightly cupped hands. Noise should sound about the same whether or not ears are covered. Safety Information: Please read, understand, and follow all safety information contained in these instructions prior to the use of this hearing protection product. Retain these instructions for future reference. Intended Use: This hearing protection product is intended to provide limited protection from harmful noise. This hearing protection product is used in loud noise environments. Use in any other application has not been evaluated by 3M and may lead to an unsafe condition.
DescriptionSLC80 23dB. Class 4. 29dB NRR. Expands slowly to fit most ear canals. Comfortable to wear over extended time. Noise reduction rating. 29 Decibels (when used as directed). The range of noise reduction ratings for existing hearing protectors is approximately o to 30 (Higher numbers denote greater effectiveness). 3M Company, St. Paul, MN. Model Classic. Federal law prohibits removal of this label prior to purchase. EPA. Label required by U.S. E.P.A. regulation 40 cfr part 211 subpart B. The EPA references to Federal relate to US Federal laws. Noise reduction rating (NRR): The U.S. Environmental Protection Agency (EPA) has selected the Noise Reduction Rating (NRR) as the measure of a hearing protector's noise-reducing capabilities. 3M makes no warranties as to the suitability of the NRR as a measure of actual protection from any noise level since such protection depends on the sound level (loudness), how long you listen to the loud sound and how well you fit the hearing protector. Although hearing protectors can be recommended for protection against harmful effects of impulse noise, the NRR is based on the attenuation of continuous noise and may not be an accurate indicator of the protection attainable against impulse noise such as gunfire. When worn according to the 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 variables will impact performance. 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, your hearing may be at risk. The NRR may overestimate the hearing protection provided during typical use due to variation in fit, fitting skill and motivation of the user.3M recommends the NRR be reduced by 50% or in accordance with applicable regulations,for estimating the amount of noise reduction provided. The NRR for the 3M Disposable Earplug is 29 dB(A). Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit. Attenuation data (ansi S3.19-1974): Test frequency (Hz): 125, 250, 500, 1000, 2000, 3150, 4000, 6300, 8000, NRR, CSA Class. Mean attenuation (dB): 37.4, 40.9, 44.8, 43.8, 36.3, 41.9, 42.6, 46.1, 47.3, 29, AL. Standard deviation: 5.7, 5.0, 3.3, 3.6, 4.9, 3.0, 3.1, 3.5, 2.7, 29, AL. 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: (1) The environmental noise level as measured at the ear is 92 dBA; (2) The NRR is 29 decibels (dB); (3) The level of noise entering the ear is approximately equal to 63 dB(A). AS/NZS 1270:2002: Test frequency (Hz): 125, 250, 500, 1000, 2000, 4000, 8000. Mean attenuation (dB): 21.7, 22.9, 25.2, 25.2, 31.9, 40.6, 39.4. Standard deviation: 7.8, 7.3, 7.8, 6.5, 4.8, 5.5, 8.9.
