RESPIRATORY PROTECTION RESPIRATORY PROTECTION RESPIRATORY PROTECTION PROTECT YOURSELF - SEEK TO UNDERSTAND An unsuitable respiratory protective device can be dangerous. The protection of respiratory airways is ensured by the following: Protection from particulates, dust and aerosols: It is often recommended to combine both functions, particularly in the presence of vapours, at ambient temperature, which can, through condensation, lead to fine droplets. • Class 1 (P1 or FFP1) for protection against course solid particles without specific toxicity (calcium carbonate) • Class 2 (P2 or FFP2) against solid and/or liquid aerosols and/or liquids indicated as dangerous or irritating (silicon dioxide – sodium carbonate) • Class 3 (P3 or FFP3) against toxic solid and/or liquids (beryllium – calcium carbonate – exotic woods) Filter use categories: Choosing a filter: Gas /Vapour protection: • Class 1 for a gas content below 0.1% in volume (filters) • Class 2 for a gas content between 0.1% and 0.5% in volume (cartridges) • Class 3 for a gas content between 0.5% and 1% in volume (large capacity canisters worn on the belt) A filtering cartridge is selected according to the following: • The toxic substances from which protection is sought • The mode of operation and length of action • The work to be performed • The devices at hand • A gas filter when the hazard involved is in gaseous form • An aerosol filter when the hazard concerns solid or liquid particulates Applications and Markings Colour mark Type Application A Organic gases and vapours (boiling point >65˚C) B Class Max. allowed gas concentration Standard 1 2 3 1000 ml/m 3 (0.1 Vol.-%) 5000 ml/m 3 (0.5 Vol.-%) 8000 ml/m 3 (0.8 Vol.-%) EN 14387 Inorganic gases and vapours (not CO), e.g. chlorine, H 2 S, HCN ... 1 2 3 1000 ml/m 3 (0.1 Vol.-%) 5000 ml/m 3 (0.5 Vol.-%) 10000 ml/m 3 (1.0 Vol.-%) EN 14387 E Sulfur dioxide and acidic gases and vapours 1 2 3 1000 ml/m 3 (0.1 Vol.-%) 5000 ml/m 3 (0.5 Vol.-%) 10000 ml/m 3 (1.0 Vol.-%) EN 14387 K Ammonia and organic ammonia derivatives 1 2 3 1000 ml/m 3 (0.1 Vol.-%) 5000 ml/m 3 (0.5 Vol.-%) 10000 ml/m 3 (1.0 Vol.-%) EN 14387 AX Organic gases and vapours (boiling point <65˚C) of low boiling substance groups 1 and 2 – Gr. 1 (100 ml/m 3 max. 40 min.)
