39、? by 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.

40、 Uncontrolled Copy, (c) BSI ? EN 133:2001 (E) 6 In general a respiratory protective device consists of two main 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. ?
41、 The facepiece can be a mask, filtering facepiece, hood, mouthpiece, helmet etc. ? The airflow through filter(s) 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 s

43、respiratory protective devices 3.2 Filtering devices (see Table 1) Filtering devices remove contaminants from the ambient air by filtration and can only protect against limited concentration ranges of known contaminants in the air if a suitable filter and facepiece are chosen. The filters in filteri
44、ng devices can be for protection against particles (particle filters), gases/vapours (gas filters), or for protection against particles and gases/vapours (combined filters). Filtering devices do not give protection against oxygen deficiency. Particle filters are divided in the following classes: ? 1
45、 Low efficiency filters; ? 2 Medium efficiency filters; ? 3 High efficiency filters. Gas filters are divided in the following classes: ? 1 Low capacity filters; ? 2 Medium capacity filters; Licensed Copy: sheffieldun sheffieldun, na, Sun Oct 29 09:22:45 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ?
