2.2 Components marking All the components that are able to affect safety by
means of ageing are marked to be easily identifiable. In particular, in the following
table are listed the components that are marked with their code and/or with the
year of manufacture, when suggested by the EN 136.1998 standard (Prospect
A.1, App. A). See Table 3
3 – WARNING AND LIMITATIONS FOR THE USE
- The BLS 5150, BLS 5400, 3150 3150V, 3400 full face masks are equipped with
one EN 148-1 connection filter holders, and therefore they must be exclusively
used with filters with the special EN 148-1 connection.
- The BLS 5250 BLS 5500 full face masks are equipped with two lateral special
connection filter holders, and therefore they must be exclusively used with filters
of the BLS series with the special threaded connection.
- The BLS 5600, BLS 5700 full face masks are equipped with two lateral bayonet
special connection filter holders, and therefore they must be exclusively used with
filters of the BLS series with the special bayonet connection.
- These full face masks are PPE which don't supply Oxygen. They can be used
together with filters only in areas where the Oxygen concentration is > 17% in
volume. (This limit may vary according to national regulations).
- The filtering device must not be used in restricted spaces (e.g. cisterns, tunnels)
because of oxygen deficiency or presence of heavy oxygen-displacing gases (e.g.
carbon dioxide).
- 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
