WARNING!
In order to avoid damage to or the deformation of the masks keep no additional loose objects in the
mask container.
For the safekeeping of the mask the mask container should be used. This also applies to masks with
installed filters, except CO and NO filters.
MSA rubber products are protected by an anti-aging agent that can become visible as a light coating.
This coating is harmless and can be removed during cleaning.
To ensure a long life for rubber components, keep them in a cool, dry place that is protected from ultra-
violet radiation, according to ISO 2230:2002, Rubber Products – Guidelines for Storage.
