Cleaning, Maintenance And Storage - BLS 5150 Gebrauchsanweisung

- Do not use the filtering respirators in oxygen enriched atmospheres
(>25%), because of the probable risk of fire or explosion.
- Do not use for respiratory protection against atmospheric
contaminants which have poor warning properties or are unknown or
immediately dangerous to life and health or against chemicals which
generate high heats of reaction with chemical filters.
- These masks are designed to be compatible with most common
headgears (helmets, ear muffs, etc.) and with the protective clothing
(coveralls); when the full face mask is used contemporaneously, for
example, with helmets for head protection or ear muffs for hearing
protection, it is necessary to keep attention to wear the respiratory
devices over the harness and however it would be better always to
check the tightness of the mask.
- These masks must not be used if the environment and contamination
are unknown. In case of doubt, insulating respirators which function
independently from the atmosphere must be used.
- Leave work area immediately, check integrity of respirators and
replace parts if: a) parts become damaged b) breathing becomes
difficult c) dizziness or other distress occurs d) you taste or smell the
contaminants or an irritation occurs.
- For the use with gas and particle filters do follow the directions and
limitations of use indicated in the relevant manufacturer's instructions.
- Never modify or alter this device.
- Do not use the masks BLS 5150 BLS 5400 BLS 5250 BLS 5500 in
explosive environments
- When a breathing protector is used in explosive atmospheres, please follow
the instructions given for such areas.
- The reference standard EN 136 does not require any chemical
permeation test. In presence of particularly aggressive chemicals it is
not guarantee the non permeability to such pollutants and it is
forbidden the use.
- Only for use by trained and qualified personal.
- Store this device in a sealed container away from contaminated areas
when it is not used.
- Beards, long sideburns or spectacle stems may interfere with
adhesion of the mask to the face and they can cause the escape of the
air. Do not use in such circumstances or the wearer will be responsible
for any damage that could be caused by this improper usage.
4 – INSTRUCTIONS FOR USE
4.1 Checking before use Before every use of the mask, it's necessary
to make a control on it, to check the good functioning. Malfunctioning or
damaged parts have to be substituted before any use.
Check procedure:
0) control the presence of these instructions and then control the mask
for any sign of damages. If this happens please contact immediately
our distributor.
1) Check, when you pull out the mask from its box; examine carefully
the mask, check that there are not damages and tearing or dirtiness
signs; check the face seal condition for deformation and intactness and
check the material that has not to be rigid;
2) Control that the exhalation valve and the inhalation valve have not
deformations, breakings or tearing. Valves have to be cleaned, not
deformed and free to move;
3) control the visor condition and cleanliness;
4) Ensure the head harness condition and elasticity and that all the
straps are fully extended.
4.2 Donning and fit checking After the check before use, don the
mask following this procedure:
1) Elongate the straps of the head harness as much as possible; put the
harness behind the neck and put the chin into the face seal, keeping the
two lower straps opened with the hands. Pull the mask over the head
and adjust it on the face. Be sure that hair does not remain trapped
between seal and forehead;
2) Adjust the side straps, then the upper straps and finally the lower
ones. Do not tight the straps excessively;
3) Negative pressure fit check, whilst wearing the mask, close the filter
holders using the palm of the hands and take a deep breath. The mask
should collapse in towards the face and remain so for as long as you
are inhaling;
4) Positive pressure fit check, place the palm of the hand over the
exhalation valve cover and exhale gently. If the mask bulges gently a
proper fit has been obtained
These checks are necessary to ensure that the face seal is fitted
correctly. If it is not, tighten the straps or adjust the mask over the face.
Then repeat the check until the fit is perfect. If the textile harness is
used (optional fittings, on demand), the procedure is the same. If you
cannot achieve a proper fit do not enter the contaminated area.
4.3 Assembling Choose the filters according to the type of
contaminant check the expiry date and screw them to the connector/s,
ensuring that the seal at the bottom of the holes makes good contact.
For a correct use of filters, see the relative user's information enclosed
to the same filters and keep attention to use filters of the same type
and class. Now, after the tightness test and the filter check, you may
enter the contaminated area. Note on respirator's use: gas filters shall
be replaced when the user begins to sense odour, taste or irritation.
Particle filters must be replaced at the latest when breathing resistance
becomes too high.
4.4 Doffing When you have finished the work, remove the mask by
loosening the lower straps on the headpiece and pulling it off from the
chin upwards. If the textile harness is used (optional fitting, on demand)
the doffing procedure is the same.

5.1 – Cleaning and disinfecting Take particular care of any
contaminants deposited on the mask. All cleaning operations should
take place in safe areas. Do not use abrasive substances to clean the
visor do not use solvents Use exclusively this procedure to clean and
disinfect the masks:
1) After removing the mask and the contaminated filter, clean under
running water to remove most of the contaminants; then clean more
fully by placing in hot water (temperature not upper to 40°C) with a
neutral soap. If disinfection is required, use a solution of a common
disinfectant (based on active chloride in sodium chloride solution for
BLS 5150 BLS 5400 BLS 5250 BLS 5500)
2) Dry the mask with a soft, clean cloth or make it dry naturally.
3) When it will be dry, clean the visor with a clean cotton wool.
5.2 Maintenance for BLS 5150 BLS 5400 BLS 5250 BLS 5500
5.2.1 Monthly and before use check (general visual check)
Examine the mask and check and check that:
1) None of the plastic parts are broken
2) There are no general signs of wear or damage
3) The seals and/or the face piece are not split
4) The membranes and the o-rings are not excessively worn
If the mask has any of these defects, it must not be used before the
faulty parts are replaced.
5.2.2 Replacing the inner mask with relative valves and valve
holders To replace the inner mask N/7 (draw. 11 BLS 5150 BLS 5400;
draw. 15 BLS 5250 BLS 5500), equipped with relative valve holders
MI/25 (draw. 12 BLS 5150 BLS 5400; draw. 11 BLS 5250 BLS 5500)
and inhalation valves NG/26 (draw. 15 BLS 5150 BLS 5400; draw. 23
