The following schedule shows the recommended minimum
maintenance procedures required in order to ensure that the
equipment is always in functional condition.
At the first signs of wear, impact marks, damage or aging of the
material, the helmet shell or harness must be replaced in order to
ensure the protective ability of the helmet is maintained. This must
be checked on a regular basis.A helmet that shows signs of
damage, e.g. cracks or scratches, that may reduce its protective
ability must be discarded. The helmet must also be discarded if it
has been exposed to stresses during an accident or near
accident, even if there is no visible damage. The helmet should be
used within 5 years after the date of production or within 3 years
of being taken into use, whichever of these dates is the earlier.
