Helmet Shell replacement
Helmets/ entire PAPR shall be stored out of direct sunlight and shells can only be replaced by returning the
units to an authorized service center. Shells shall be replaced at least every ten years.
If the helmet shell is damaged, heavily scratched, or has been subject to significant impact, the shell shall
be replaced.
The Hi-Visibility color property of Hi-Visibility helmet shells may be compromised (become dull) as
scratches, scuffs, and similar wear and tear damages accumulate. Where Hi-Visibility colors are needed or
required, consideration should be given to replacing these helmet shells on an as needed basis, regardless
of the age of the shell. Aggressive or abrasive cleaning or cleaners may hasten the degradation (dulling) of
the hi-visibility color property.
