FAQ 4251+ Maintenance-free gas and vapour half mask with FFA1P2R D valve 3MK4251+
- What is the meaning of the FFA1P2R D marking on this mask?
- The FFA1P2R D marking indicates protection against organic vapours with a boiling point higher than 65°C, as well as protection against solid and liquid particles. The R signifies that the filter is reusable for multiple shifts depending on saturation, and the D indicates resistance to clogging by dolomite dust.
- How do I determine the right time to replace the 4251+ half mask?
- Replacement is necessary when the filter is saturated, which is indicated by the perception of odours or tastes through the mask. In accordance with occupational health guidelines, it must also be discarded if the mask is physically damaged or if the expiry date indicated on the packaging has been reached.
- Can this mask be used in environments with low oxygen levels?
- No, this mask is a filtration device and does not provide oxygen. It is strictly forbidden to use it in confined spaces or oxygen-deficient atmospheres, where a self-contained or supplied-air breathing apparatus is required.
