WARNING!
If the insert is pinched between the cushion and the cup of the hearing protector, the acoustic performance can be
affected.
Failure to follow this warning can result in serious injury including but not limited to permanent hearing loss.
LIFE CYCLE AND EXPIRATION DATES
Life cycles of the ear-muffs vary according to environment and type of work where it is used, as well as correct wear by the
user. Environmental climatic conditions and exposure to weather also influence durability of the protector, e.g. prolonged
exposure to sunlight or contaminants present in the environment.
The replacement of the ear-muffs as well as cushions and inserts should be made whenever they are deformed, broken,
torn, hardened or with change in their original shape, size, color or softness. The ear-muffs or hygiene kits replacement
periodicity must be defined by the employer through analysis considering kind of activity, processes, work environment,
application of use and conservation.
Product expiration date: 05 years (from manufacturing date, if kept in the package in a clean and dry place)
Life cycle of ear-muffs after opening the package: Variable depending on the application.
MSA recommends to replace the ear-muffs in a maximum period of 3 (three) years, considering the continuous use in an
average working day of 8 hours.
COMPATIBILITY FOR HELMET MOUNTED EAR-MUFFS (Table 2)
These helmet mounted ear-muffs are of 'small size range' or 'large size range' (depending on the case). EN 352-3:2002
states the following "Helmet mounted ear-muffs complying with EN 352-3:2002 are of 'medium size range' or 'small size
range' or 'large size range'. 'Medium size range' helmet mounted ear-muffs will fit the majority of wearers. 'Small size range'
or 'large size range' helmet mounted ear-muffs are designed to fit wearers for whom 'medium size range' helmet mounted
ear-muffs are not suitable".
For compatibility reason between the helmet and the ear-muff, the helmet adapter may have to be changed on the ear-muff
according to picture I.
These ear-muffs must be fitted to, and used only with, the industrial safety helmets listed in Table 2, which also shows the
applicable size range and correct adapter type. Additional helmets may have been approved following publication of these
instructions for use. For further information, contact your distributor.

WARNING!
• Ensure that the ear-muffs or the ear-muff/safety helmet combination:
- Are fitted properly and maintained in accordance with these instructions for use,
- Are worn at all times in noisy surroundings,
- Are inspected before each use for flexibility of the cushions, serviceability and for achieving a tight seal against the
head all around the ears,
- Are inspected before each use for damage including cracks, tears within the sealing ring.
• Ear muffs with any damage must be removed from service"
• Exposure to low temperatures while in storage or otherwise not in use may affect the acoustic performance of the
ear muffs if the foam is not allowed to warm before use. Before entering noisy surroundings, allow sufficient time with
the ear muffs on the head or in a room temperature environment for the cushions to warm, regain their flexibility and
achieve a tight seal against the head all around the ears.
• Interference with the seal between the ear-muffs and head by an object such as, but not limited to, respirator straps or
spectacle arms, can reduce the noise attenuation of the ear-muffs.
• The fitting of hygiene covers to the cushions may affect the acoustic performance of the ear-muffs.
• Not intended for high temperature applications.
• The ear-muffs are made for the intended use only.
• In the event that the ear-muffs need to be removed, exit the danger zone first and then remove the ear-muffs.
• If the recommendations given are not adhered to, the protection afforded by the ear-muffs can be severely impaired.
