RSG 400 Series Full Face Mask Instruction Manual

RSG 400 Series Full Face Mask

The RSG 400 Series Full Face Mask is a CE-marked full face mask (class 2) designed to protect the user’s eyes and respiratory organs against harmful aerosols, fumes, and gases. The mask is tested and approved in accordance with EN 136:1998 CL2 and has a standard thread connection in accordance with EN 148-1. The full face mask is produced in two material types, Neoprene Rubber (40 02 01) and Silicone (40 01 01), both of which are kind to the skin and provide a comfortable fit. The mask has a large visor that is resistant to impact and ensures an extensive field of vision to all sides.

GENERAL

• The mask is a CE-marked full face mask (class 2), tested and approved in accordance with EN 136:1998 CL2, and standard thread connection in accordance with EN 148-1. The RSG 400 Series full face mask in combination with the T-Air PAPR is approved according to EN 12942: 2009, class TM3P.

• The mask covers the eyes, nose, mouth and chin. The full face mask protects the user’s eyes and respiratory organs against harmful aerosols, fumes and gases. The mask is produced in 2 material types

• Neoprene Rubber is a soft material which is kind to the skin and is suitable for the majority of working situations in which a half mask is required.
  Silicone is kind to the skin, and is a very soft and comfortable material which is only affected by ageing to an extremely limited degree. Perfect for tasks where there is, for instance, a risk of adhesion of dyes.

• The mask body, which consists of kind-to-the-skin neoprene rubber / silicone, is constructed with a double sealing border which thus provides an extra safety zone.

• The mask is constructed with an inner mask of soft neoprene rubber / silicone, which is kind to the skin. Two large valves ensure that the inhalation resistance is very small.

• The mask is equipped with adjustable straps (“quick release”) made from kind-to-the-skin neoprene rubber / silicone which ensure a rapid, perfect and comfortable fit.

• The mask has a large visor which is resistant to impact and ensures an extensive field of vision to all sides.

• The mask is designed so that the incoming air passes over the visor and prevents it from misting up. However, in the event of a large temperature difference between the visor’s inner and outer side, it is recommended that an anti-misting agent be used (e.g., “Klar-Pilot Fluid Super”).

• The mask is equipped with a very effective speech membrane made of synthetic film.

APPLICATION/LIMITATION

The RSG full face mask can be used in two different configurations:

• Together with filters from. the RSG filter program.
• Together with RSG T-Air PAPR.

When the mask is used with the T-Air, the manual for the relevant equipment must be observed .
If the polluted air’s oxygen content is 17-21% (volume), the mask can be used with a gas, particle or combined filter. Use an oxygen meter to ascertain the oxygen content of the air. Follow the filter’s instructions for use carefully. The filter must be equipped with a standard thread connection approved in accordance with EN 148-1 . If the oxygen content of the air is less than 17% (volume), or if the gas concentration exceeds the maximum allowable gas concentrations in relation to the gas filter class used, as shown in table 4 (see page 10), an air-supplied respirator which is independent of the surrounding air must be used. This equipment must be equipped with a standard thread connection approved . in accordance with EN 148-1. Follow the instructions for use for the equipment carefully.
If the user has certain physical features (such as a beard or thick sideboards), then the mask might not give a satisfactorily tight fit to the face. This will also apply if spectacle frames obstruct the facial seal. In such cases, the user carries the risk of damage to his health.1
In areas where the use of respiratory equipment is necessary, there is often a danger of explosion. If this is the case, then the relevant precautions must be observed.1
Leave the area immediately, check the mask and replace parts if:

1. The mask, parts thereof, or filters are damaged.
2. Breathing difficulties occur.
3. Dizziness or indisposition occurs.
4. Pollution can be tasted or smelt, or other irritation occurs.

The mask must never be modified or altered.

PUTTING ON – ADJUSTING – REMOVING

PUTTING ON THE MASK

1. Put the carrying strap around the neck. Loosen all the straps on the mask and spread them out completely. Put on the mask with the chin section first.
2. The mask should be pulled in towards the face, and the straps pulled over the head and down towards the back of the head until the headband is flat.

ADJUSTMENT

Adjust the mask until it sits correctly:

• A. Both neck straps should be tightened (pulled backwards) simultaneously.
• B. Both temple straps should be tightened (pulled backwards) simultaneously.
• C. If the forehead strap is not flat and tight (for example, if the head is smaller than average), the forehead strap should be tightened by pulling it backwards.

REMOVAL
The neck straps’ quick release buckles should be loosened, the mask pulled down away from the face and then up over the head (the temple straps can be loosened in the same manner).

CHECK – SUB-COMPONENT NUMBERS – CLEANING

CHECK BEFORE USE

• THE MASK
  The mask must always be cleaned after use and checked for leakage and function with a suitable leakage analyser (refer to intervals between function and leakage tests in table 2, page 9). The mask must always be checked before use in order to ensure that the full face mask is not damaged and is clean. It is extremely important that a mask leakage test (see below) is always carried out before

• MASK LEAKAGE TEST
  The mask’s screw thread opening should be covered by the hand so that air cannot enter the mask from outside, whilst at the same time inhaling and holding the breath for approx. 10 seconds. Repeat the test 2-3 times. If outside air enters the mask, tighten the straps further (see “Adjustment”, page 4). If the air cannot be prevented from entering the mask by tightening the straps, a detailed examination of the mask’s individual components is necessary.

SUB-COMPONENT NUMBERS

Sub-components which have a particular significance for safety are marked so that they can be identified – refer to table 5, page 10.

CLEANING
After removing the filter or air supply pipe, the mask should always be cleaned after use in lukewarm water to which a mild detergent has been added (e.g., washing-up liquid or a liquid washing machine detergent) which does not contain perborate. If the mask is very dirty, a brush can be used to clean it. Do not use solvents (e.g., benzine or spirit) or very warm water (max. 60°C). The mask should be rinsed thoroughly in lukewarm running water (refer to cleaning intervals in table 2, page 9).

DISINFECTION – DRYING – STORAGE

• DISINFECTION
  Disinfect the mask components in a suitable solution after use. Use a disinfectant such as “MULTIDOR”. Follow the instructions carefully (refer to disinfection intervals in table 2, page 9).

• DRYING
  The mask should be air-dried or dried in a drying cabinet at a temperature not exceeding 60°C. Avoid direct sunlight.

• STORAGE
  Loosen the mask straps as much as possible. Avoid deformation. Remember to use the storage brace in the full face mask during storage. Store the mask in airtight and light-proof packaging in a cool and dry place.

  • Storage and operating temperature: -10oC – +50oC.
  • Relative humidity <95% .

NOTE
Silicone has a tendency to absorb detergents and disinfectants. Irritation of the skin can occur as a result. Therefore:

1. Reduce the time the substances are in contact with the mask, which is stated in the instructions, to a minimum.
2. Rinse thoroughly in running water for 10 minutes, after cleaning and disinfection of the mask 40 01 01.

MAINTENANCE

1. REPLACING THE VISOR
   If the visor is damaged or the field of vision reduced, it must be replaced. The two screws in the visor frame can be loosened with a screwdriver. The visor frame and the visor can then be removed. The new original visor should be secured in the silikone frame so that the two centre markings on the visor are located exactly opposite the centre markings on the silicone frame. The two-piece visor frame should then be positioned correctly and screwed firmly in place. After replacement of the visor, a leakage test must be carried out using a suitable leakage analyser.

2. REPLACING THE EXHALATION VALVE MEMBRANE
   The exhalation valve cover can be removed by gently pulling it out. If the membrane is deformed, split or otherwise damaged, it must be replaced. Remove the membrane by taking hold of the edge and pulling outwards. Fit a new original membrane by pressing it down fully onto the valve seat’s connection piece. Check that the valve seat is clean and undamaged. If the valve seat is damaged, the entire valve housing must be replaced. After replacing the exhalation valve membrane, a leakage test must be carried out using a suitable leakage analyser.

3. REPLACING THE INHALATION VALVE MEMBRANE AND VALVE SEAT
   If the inhalation valve membrane is deformed, split or otherwise damaged, it must be replaced. The membrane can be replaced by removing the rubber valve seat, which also acts as a packing. A new original membrane should then be fitted onto the inlet valve pin, and the valve seat pressed, with the inhalation valve membrane first, through the valve housing’s opening. The valve seat is pressed through until it falls into place. Make sure that the membrane is not restricted in its movement. After replacing the inhalation valve membrane and valve seat, a leakage test must be carried out using a suitable leakage analyser.

4. REPLACING THE CONTROL VALVE MEMBRANE
   If the control valve membrane is deformed, split or otherwise damaged, it must be replaced. The membranes can be removed by taking hold of the edges and carefully pulling them out of the valve seat. New original membranes can be fitted by locating their rubber connection piece in the hole at the centre of the valve seat, and then, on the outside of the inner mask, carefully pulling the connection piece until the membrane sits tight and flat against the valve seat.

5. REPLACING THE SPEECH MEMBRANE
   The mask’s inner mask can be removed by pulling gently. The screw ring can be screwed out and the speech membrane’s cover removed. Then take out the membrane and the O-ring. A new O-ring and membrane can then be fitted. The cover and screw ring are mounted once again and the inner mask refitted. After replacement of the speech membrane, a leakage test must be carried out using a suitable leakage analyser.

6. REPLACING THE VALVE HOUSING (COMPLETE)
   The mask’s inner mask can be removed by pulling it gently. The closing band can be loosened with a screwdriver and removed. “Support for valve housing” can be removed from the visor frame and the complete valve housing can be pulled out of the body of the mask. A new original valve housing can be put in place, “support for valve housing” fitted onto the visor frame, and finally the closing band can be refitted and tightened properly. After replacement of the complete valve housing, a leakage test must be carried out using a suitable leakage analyser
