This excludes any other risk (head protection, etc.)
In the power-off state, little or no respiratory protection is to be expected. This is considered to
be an abnormal situation. A rapid build-up of carbon dioxide and depletion of oxygen within
the hood may occur.
Filters shall only be fitted to the turbo unit and not directly to the helmet/hood.
The user should not confuse the markings on a filter relating to any standard other than EN
12941 with the classification of this device when used with this filter.
