• The respirator filters must be earthed via a dissipative mask and via the wearer's earthing with a leakage resistance <108 Ω
• The respirator filters must not be used in areas where high charge generation processes are expected
• The respirator filters must only be worn on the face mask and not on the belt in explosive atmospheres
• Each individually sealed in PE bags and packed in an outer carton

The permissible ambient temperature must not exceed 70 °C, based on a temperature increase of 10 K in normal operation and in the event of a fault (zone 1 or 21) or in normal operation (zone 2 or 22) due to the activated carbon filter on the parts in contact with a potentially explosive atmosphere.
