37、y purifying the ambient air to be breathed using filters able to remove contaminants in the air - filtering devices or - by supplying the wearer with breathable gas from an uncontaminated source - breathing apparatus. 5 EN 133:2001 (E) In general a respiratory protective device consists of two main
38、components, a facepiece and filter(s) or a facepiece and a means of providing uncontaminated breathable gas. The facepiece directs this breathable gas to the wearers nose and mouth area. - The facepiece can be a mask, filtering facepiece, hood, mouthpiece, helmet etc. - The airflow through filter(s)
39、 may be assisted or unassisted. - The means of supplying breathable gas may consist of pressure cylinders, compressed air line system, fresh air supply system, or another suitable supply system. - Following this, RPDs are classified according to Figure I.

41、 can only protect against limited concentration ranges of known contaminants in the air if a suitable filter and facepiece are chosen. The filters in filtering devices can be for protection against particles (particle filters), gases/vapours (gas filters), or for protection against particles and gas
42、es/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
43、capacity filters; - 2 Medium capacity filters; 6 EN 133:2001 (E) Gas filters and combined filters - 3 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 the classification of the appropriate European Standards.
44、Filters can be combined filters or multi type gas filters (see EN 132).
