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. The filter system with a layer of carbon protects wearers from unpleasant odors on top of the required breathing protection.
