The storage of equipment should be
in accordance with the manufacturer’s
instructions.
Storage package protection should be
constructed such that mechanical damage
to the equipment inside the package will
not cause a leak of the refrigerant charge.
The maximum number of pieces of
equipment permitted to be stored together
will be determined by local regulations.
1.
Checks to the area. Prior to beginning
work on systems containing ammable
refrigerants, safety checks are
necessary to ensure that the risk of
ignition is minimised. For repair to
the refrigerating system, the following
precautions shall be complied with
prior to conducting work on the
system.
2.
Work procedure. Work shall be
undertaken under a controlled
procedure so as to minimise the
risk of a ammable gas or vapour
being present while the work is being
performed.
3.
General work area. All maintenance
sta and others working in the local
area shall be instructed on the nature
of work being carried out. Work in
conned spaces shall be avoided.
The area around the workspace shall
be sectioned o. Ensure that the
conditions within the area have been
made safe by control of ammable
material.
4.
Checking for presence of refrigerant.
The area shall be checked with an
appropriate refrigerant detector prior
to and during work, to ensure the
technician is aware of potentially
ammable atmospheres. Ensure that
the leak detection equipment being
used is suitable for use with ammable
refrigerants, i.e. nonsparking,
adequately sealed or intrinsically safe.
