35、 protection:by purifying the ambient air to be breathed using filters able to remove contaminants in the air - filteringdevices orby supplying the wearer with breathable gas from an uncontaminated source - breathing apparatus.EN 133:2001 (E)6In general a respiratory protective device consists of two

36、 main components, a facepiece and filter(s) or a facepieceand a means of providing uncontaminated breathable gas. The facepiece directs this breathable gas to thewearers nose and mouth area.The facepiece can be a mask, filtering facepiece, hood, mouthpiece, helmet etc.The airflow through filter(s) m

37、ay be assisted or unassisted.The means of supplying breathable gas may consist of pressure cylinders, compressed air line system, freshair supply system, or another suitable supply system.Following this, RPDs are classified according to Figure 1.Respiratory protective devicesFiltering devices(depend

40、 gases/vapours (combined filters).Filtering devices do not give protection against oxygen deficiency.Particle filters are divided in the following classes:1 Low efficiency filters;2 Medium efficiency filters;3 High efficiency filters.Gas filters are divided in the following classes:1 Low capacity fi

41、lters;2 Medium capacity filters;EN 133:2001 (E)73 High capacity filters.and further divided in types according to the gases they protect against e.g. filter types A, B, E or K according to theclassification of the appropriate European Standards.Filters can be combined filters or multi type gas filte
