FFP1 Class
- protection from atoxic and non-fibrogenic kinds of dust
- inhaling may result in development of health conditions; can also irritate the respiratory system and cause unpleasant odors
- total leakage may amount to a maximum of 25 %
- this kind of mask may be applied under a fourfold OEL transgression at the most
Protection class FFP1 respirator masks are made for working environments in which neither poisonous nor fibrogenic kinds of dust and aerosols are to be expected. They filter at least 80 % of the particles measuring up to 0.6 μm and may be worn as long as the maximum workplace concentration transgression measures no more than the fourfold value. The building or food industry put FFP1 respirator masks to use in many cases.
FFP2 Class
- protection from firm and fluid deleterious kinds of dust, smoke, and aerosols
- particles may be fibrogenic – which means they irritate the respiratory system in the short term and can result in reduction of elasticity of pulmonary tissue in the long run
- total leakage may amount to a maximum of 11%
- OEL transgression to the tenfold value
Protection class FFP2 respirator masks are made for working environments in which deleterious and mutagenic particles can be found in the breathing air. Respirator masks of this class must contain at least 94 % of the particles measuring up to 0.6 μm and may be used in environments transgressing the OEL up to a maximum of the tenfold concentration. The same goes for the TRK value (technical reference concentration). Protection class FFP2 respirator masks are often worn in the metal and mining industry. Workers in these industries are frequently in contact with aerosols, fog and smoke that result in conditions of the respiratory system such as lung cancer in the long term. On top, they harbor the massive risk of secondary diseases and active tuberculosis of the lung. Our uvex filter system with a layer of carbon protects wearers from unpleasant odors on top of the required breathing protection.
FFP3 Class
- protection from poisonous and deleterious kinds of dust, smoke, and aerosols
- when working with oncogenic or radioactive substances or pathogens such as viruses, bacteria and fungal spores FFP3-class respirator masks are recommended
- total leakage may amount to a maximum of 5%
- OEL transgression to the thirtyfold value
Protection class FFP3 respirator masks offer maximum protection from breathing air pollution. The total leakage may amount to a maximum of 5% and they must filter 99% of all particles measuring up to 0.6 μm. This kind of mask also filters poisonous, oncogenic and radioactive particles. Protection class FFP3 masks are used in working environments transgressing the OEL by the thirtyfold industry-specific values. They are often used in the chemistry industry.
