1 Safety Regulations

1.1 Correct Use

G1 Facepieces - hereafter called masks -are full face masks with a positive pressure connection. They are not complete respiratory protective devices by themselves, but serve as facepieces [EN 136 CL3+] for use with compressed air breathing apparatus of the G1 series and respiratory filters.

The mask as part of a respiratory protective device ensures an appropriately tight fit of the user’s face against the ambient atmosphere.

When using a compressed air breathing apparatus, the operating manual for the compressed air breathing apparatus must be read and observed.

If the mask is used as part of a filtering device using the filter adapter, respiratory protective filters equipped with a standardized thread according to EN 148-1 must be used.The type and concentration of contaminants and the oxygen concentration in the ambient air must be known to decide if the use of a filtering device is permissible. The instructions for use of the respiratory filters have to be regarded, including any information regarding the use in potentially explosive atmospheres. When in doubt use a supplied air breathing apparatus. The permitted minimum oxygen concentration of ambient air depends on national regulations.

When used in oxygen or an enriched-oxygen atmosphere, the increased potential hazard of flammability has to be regarded.

WARNING!

According to the European directive 89/656/EC it has to be verified before first use of the mask that a correct size has been chosen (proper tight fit), that the mask can be worn in combination with other protective equipment (for example a protective jacket), that it is a correct choice for the conditions at the particular place of use and that it fulfils the ergonomic requirements.

2 Description

1 2

11a

11b

The inhalation air flows from the component housing of the mask past the inhalation valve to the inside of the lens (thus keeping the lens fog-free) and then through the inlet valves into the nosecup.

The exhalation air passes through the exhalation valve directly to the ambient air.

Fixed Push-to-Connect component housing only: If in a safe atmosphere no demand valve is attached, ambient air can be inhaled directly through an open port to facilitate breathing and speaking with no resistance.

The faceblank is made of a special soft rubber compound and assures a snug, comfortable fit and a tight seal. The mask and the nosecup are available in 3 sizes (small, medium, large).

The mask is available with different head harnesses and different component housings.
