4.2.
Areas of use
The fresh air hose devices in the series 6500/6501 comprising the basic unit 6500/6501, a full-face mask, an air feed hose
and for the series 6501, also a blower. The breathing apparatus is only functional and ready for use once the connections
between these components have been tightly sealed.
The device can be used in accordance with the valid conditions in the commercial professional associations in
atmospheres where the air pollutants display concentrations of up to 1,000 times the limit value*. Please ensure that the
suction strainer/blower is mounted and securely fixed in a position where there is unpolluted air. Particular care must be
taken in the case of harmful gas that is heavier than air and therefore concentrated close to the floor. In this case we
recommend mounting the suction end of the hose at a height of at least 1.5 m.
*: Limit values in the sense of this information are the highest permitted concentrations (without breathing protection) of
harmful gases and/or particles in the surrounding atmosphere (MAK / TRK - values).
Fresh air hose devices are isolated units that are the safest type of breathing apparatus. Their use becomes necessary if
one of the following conditions is fulfilled:
- if the oxygen content of the surrounding atmosphere is below 17 % by volume,
- if the type or concentration of the pollutants is unknown,
- If the type, combination or concentration of pollutants rules out the use of filter devices,
- if the conditions of use are not exactly known,
- if the opportunity of a rapid withdrawal from the hazardous area is not given,
- if the intake of even the smallest quantities of the pollutant causes damage to health,
- if the composition of the surrounding atmosphere can deteriorate (e.g. in restricted spaces such as ditches, containers,
ducts etc.).
