3M H520A Earmuffs Headband

STANDARD

352-1:2020

3M strongly recommends personal fit testing of hearing protectors. Research suggests that users may receive less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in fit, fitting skill, and motivation of the user. Refer to applicable regulations and guidance on how to adjust attenuation label value(s). In the absence of applicable regulations, it is recommended that the attenuation label value(s) be reduced to better estimate typical protection.

INTRODUCTION

  1. INTENDED USE
    These earmuffs are intended to help provide workers with protection against hazardous noise levels. It is expected that all users read and understand the provided user instructions as well as be familiar with the use of this device.
    3M PSD products are occupational use only.
    In Europe, some 3M PELTOR products may also be appropriate for certain non- work uses.
    Always read and follow the User Instructions.

  2. CARRIER
    The word carrier used in this document refers to head protection, face protection and/or non-protective devices.

SAFETY

IMPORTANT
Please read, understand, and follow all safety information in these instructions prior to use. Retain these instructions for future reference. For additional information or any questions, contact 3M Technical Services (contact information listed on the last page).

WARNING
This hearing protector helps reduce exposure to hazardous noise and other loud sounds. Misuse or failure to wear hearing protection at all times when exposed to hazardous noise may result in hearing loss or injury. For proper use, see supervisor, User Instructions or call 3M Technical Services. 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, leave the noisy environment immediately and consult a medical professional and/or your supervisor.

Failure to follow these instructions may reduce the protection provided by the earmuff and may result in hearing loss:

  • 3M strongly recommends personal fit testing of hearing protectors. Research suggests that users may receive less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in fit, fitting skill, and motivation of the user. Refer to applicable regulations and guidance on how to adjust attenuation label value(s).
    In the absence of applicable regulations, it is recommended that the attenuation label value(s) be reduced to better estimate typical protection.

  • Ensure the hearing protector is properly selected, fit, adjusted, and maintained. Improper fit of this device will reduce its effectiveness in attenuating noise. Consult the enclosed instructions for proper fit.

  • Inspect the hearing protector before each use. If damaged, select an undamaged hearing protector or avoid the noisy environment.

  • When additional personal protective equipment is necessary (e.g. safety glasses, respirators, etc.), select flexible, low profile temples or straps to minimize interference with the earmuff cushion. Remove all other unnecessary articles (e.g. hair, hats, jewelry, headphones, hygiene covers, etc.) that could interfere with the seal of the earmuff cushion and reduce the protection of the earmuff.

  • Do not bend or reshape the headband, neckband or carrier attachment and ensure there is adequate force to hold the earmuffs firmly in place.

  • Earmuffs, and in particular cushions, may deteriorate with use and should be examined at frequent intervals for cracking and leakage, for example. When used regularly, replace the ear cushions and foam liners at least twice a year to maintain consistent protection, hygiene, and comfort.

  • If the requirements above are not adhered to, the protection afforded by the earmuffs will be severely impaired.

352 Safety Statements:

  • The fitting of hygiene covers to the cushions may affect the acoustic performance of the earmuffs.

  • This product may be adversely affected by certain chemical substances. Further information should be sought from the manufacturer.

  • H510F, H520F: These earmuffs are of large size range. Earmuffs complying with EN 352-1 are of “medium size range” or “small size range” or “large size range”.
    “Medium size range” earmuffs will fit the majority of wearers. “Small size range” or “large size range” earmuffs are designed to fit wearers for whom “medium size range” earmuffs are not suitable.

  • H510P3, H520P3, H540P3, H31P3: These earmuffs attached to head protection and/or face protection devices are of ‘large size range’. Earmuffs attached to head protection and/or face protection devices complying with EN 352-3 are of ‘medium size range’, ‘small size range’ or ‘large size range’. ‘Medium size range’ earmuffs will fit the majority of users. ‘Small size range’ or ‘large size range’ earmuffs are designed to fit users for whom ‘medium size range’ earmuffs are not suitable.

NOTE

  • When worn according to these 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. To learn more about hearing protection for impulse noise, visit www.3M.com/hearing.
  • Operating temperature range: -20 °C (-4 °F) to 50 °C (122 °F).
  • Attention – Product imagery is for illustration only.

FITTING INSTRUCTIONS

Inspect the hearing protector before each use. If damaged, select an undamaged hearing protector or avoid the noisy environment.

HEADBAND

(Figure D)
D:1 Adjust the height of the cups by sliding them up or down while holding the headband in place.
D:2 The headband should be positioned across the top of the head as shown and should support the weight of the earmuff.

NECKBAND
(Figure D)

  • D:3 Place the cups in position over the ears.
  • D:4 Keep the cups in position, place the head strap on top of your head and lock it tight in position.
  • D:5 The head strap should be positioned across the top of your head and should support the weight of the headset.

CARRIER ATTACHMENT
(Figure D)

  • D:6 Insert the carrier attachment in the slot on the carrier and snap it into place (D:7).
  • D:8 Work mode: Press the headband wires inwards until you hear a click on both sides. Make sure that the cups and the headband wires do not press on the edge of the carrier when in work mode as this could reduce the noise attenuation of the earmuff.
  • D:9 Ventilation mode: To switch the unit from work mode to ventilation mode, pull outward on the ear cups until you hear a click. Avoid placing the cups against the carrier
  • (D:10) as this prevents ventilation.

PRODUCT LIFETIME

It is recommended that you replace your product within 5 years from date of manufacture. The lifetime of the product will be highly dependent on the environment in which the product is stored, used, serviced, and maintained. The user must regularly inspect the product to determine when it has reached its end of life. Examples that the product may have reached its end of life are:

  • Visible defects such as cracks, deformations, loose or missing parts.
  • Experience of a deterioration in the hearing protector’s attenuation performance.

CLEANING AND MAINTENANCE

Use a cloth wetted with soap and warm water to clean the outer shells, headband and ear cushions.

NOTE: Do NOT immerse the hearing protector in water.
If the hearing protector gets wet from rain or sweat, turn the earmuffs outwards, remove the ear cushions and foam liners, and allow to dry before reassembly. The ear cushions and foam liners may deteriorate with use and should be examined at regular intervals for cracking or other damage. When used regularly, 3M recommends replacing the foam liners and ear cushions at least twice a year to maintain consistent attenuation, hygiene, and comfort. In hot and humid environments more frequent changes may be required to maintain acceptable hygiene. If an ear cushion is damaged, it should be replaced. See Spare Parts section below.

REMOVING AND REPLACING THE EAR CUSHIONS

(Figure D)

  • D:11 To remove the ear cushion, slide your fingers under the inside edge of the ear cushion and firmly pull straight out.
  • D:12 Remove existing liner(s) and insert new foam liner(s). D:13 Fit one side of the ear cushion into the groove of the earcup and then press on the opposite side until ear cushion snaps in place.
