MOLDEX FOAM EARPLUGS:
1. Use these laboratory derived attenuation data for comparison purposes only. The amount of protection afforded in field use often is
significantly lower depending upon how the protectors are fitted and worn.
2. Failure to follow all instructions could result in hearing loss or injury.
3. Failure to obtain a proper fit will reduce effectiveness of hearing protectors and could result in hearing loss or injury.
4. Over protection can be dangerous. The wearer must be able to hear warning signals.
5. Wearers with hearing loss should exercise extreme caution.
6. It is the employer’s responsibility to ensure that the type of hearing protector and its rating is appropriate for the user in their
7. Failure to follow these warnings could result in serious injury or death.
8. Moldex foam earplugs must only be used as part of a hearing conservation program that complies with applicable local safety and
INSTRUCTIONS FOR USE:
Moldex foam foam earplugs must be fitted and worn correctly to provide effective protection. Consult your supervisor or an
audiologist before wearing. Wash or clean hands before use.
1. ROLL & COMPRESS With clean hands, hold earplug between thumb and forefinger as shown. Roll and progressively compress the
entire tapered end of the earplug to a small wrinkle-free cylinder.
2. INSERT To ensure fitting, reach hand overhead and gently pull ear upward and outward as shown. Insert compressed, tapered end of
earplug well inside ear canal. Hold 30-60 seconds until earplug expands. Release, then push in again for 5 seconds to ensure fit.
3. CORRECT FIT When properly inserted, the bottom edge of earplug is located at the opening of the ear canal.
4. INCORRECT FIT A portion of the earplug not in the ear canal will reduce effectiveness.
5. USER FIT CHECK In a noisy environment with earplugs inserted, cup hands over both ears and release. If the earplugs are inserted
correctly, you should not notice a significant difference in attenuation. If a proper fit has not been obtained, move to a quiet area and
repeat fitting instructions.
6. EARPLUG REMOVAL Remove earplug slowly. Use a gentle twisting motion to gradually break the seal. Rapid removal may damage
EARPLUGS USED FOR IMPULSE NOISES SUCH AS SHOOTING GUNS – WARNING:
No earplug can completely protect the user from exposure to impulse sound and in particular to gunfire or
weapons fire. When properly fitted and worn will reduce exposure to harmful levels of impulse sound but cannot
completely eliminate such exposure either through the ear canal or through bone conduction. Hearing loss may
still occur even with proper fitting and use of any impulse noise earplug.
Properly fitted passive slow recovery foam earplugs either alone or combined with high NRR earmuffs will provide
greater protection from impulse sound to the user than any reusable impulse earplug but also cannot eliminate
such exposure either through the ear canal or through bone conduction.
Accordingly, hearing loss may still occur as a result of sustained or repeated exposure to impulse sound.
However, slow recovery foam earplugs, either alone or with earmuffs, will not allow the user to hear commands,
approaching vehicles or other sounds the user may need to hear.
