Airborne Noise Emission
The A-weighted sound pressure emitted by
this product is below 70 dB.
** The noise level can vary depending on the
site.
The figures quoted are emission level and are
not necessarily safe working levels.
Whilst there is a correlation between the
emission and exposure levels, this cannot be
used reliably to determine whether or not
further precautions are required.
Factor that influence the actual level of
exposure of the workforce include the
characteristics of the work room and the other
sources of noise, i.e. the number of
equipment and other adjacent processes and
the length of time for which an operator
exposed to the noise. Also, the permissible
exposure level can vary from country to
country.
This information, however, will enable the
user of the equipment to make a better
evaluation of the hazard and risk.
Limiting concentration
Limiting concentration is the limit of Freon gas
concentration where immediate measures can
be taken without hurting human body when
refrigerant leaks in the air. The limiting
concentration shall be described in the unit of
3
kg/m
(Freon gas weight per unit air volume)
for facilitating calculation.
Limiting concentration: 0.44 kg/m
