2. PRECONDITIONS FOR USE
FreshAir Flow Control respiratory system can be used for protection against
solid and liquid particles in breathing air in welding and similar processes.
Do not use it against toxic gases and vapours.
Before you can use the system correctly and safely, you must fully
understand all of the following precautions.
• Oxygen concentration in the surrounding area must not drop under
17%.
• Type and concentration of the contaminants in the working place
must be known to the user.
• The FreshAir respiratory system must not be used in unventilated
areas such as tanks, pipes, channels etc.
• The FreshAir respiratory system must not be used in areas with danger
of explosion.
• The respiratory system must only be used with the blower unit
switched on.
• The air flow must be checked before use.
• If the blower unit stops working for any reason, the user must leave
the contaminated area immediately.
• If the blower unit is switched off, the respiratory system gives little or
no respiratory protection. There is also a risk of high concentration of
carbon dioxide (CO₂) and of oxygen reduction inside the headpiece.
NOTE! During a period of really hard work when user’s breathing
becomes very intense, pressure may decrease inside the hood and thus
the protective effect can decrease.
• The headpiece must fit the user´s face perfectly, only then the
efficiency of the system is sufficient. The protective effect of the
complete system is reduced, if the seal of the headpiece is not fitted
properly, for example, due to beards or long hair breaking the seal.
• It must be ensured that the air hose does not make a loop and does
not get caught or trapped in the surroundings.
• Respiratory system FreshAir Flow Control is restricted for protection
against solid and liquid particles only. Do not use it against toxic gases
and vapours.
• It is essential to choose the correct type of filter according to the type
of contamination.
• A particle filter must not be used for protection against gases.
• A gas filter must not be used for protection against particles.
