a degree of ventilation shall continue during the period that the
work is carried out. T

ventilation
should
safely
disperse
any
released
refrigerant
and
preferably
expel it externally into the
atmosphere.
1.1.9 Checks to the refrigeration equipment. Where electrical
components are being changed, they shall be fit for the
purpose and to the correct specification. At all times the
manufacturer’s maintenance and service guidelines shall be
followed. If in doubt consult the manufacturer’s technical
department for assistance.
The following checks shall be applied to installations using
flammable refrigerants.
The charge size is in accordance with the
room size within which the refrigerant containing
parts
are
installed;
th

ventilation
machinery
and
outlets
are
operating
adequately and are not obstructed; if an indirect refrigerating
circuit is being used, the secondary circuit shall be checked for
the presence of refrigerant; marking to the equipment
continues to be visible and legible.
markings
and
signs
that
are
illegible
shall
be
corrected;
refrigeration
pipe
or
components are
installed in a position where they are unlikely to be exposed to
any substance which may corrode refrigerant containing
components, unless
the components are constructed of
materials which are inherently resistant to being corroded or are
suitably protected against being so corroded.
Checks to electrical devices. R

and
maintenance
to
electrical
components
shall
include
initial
safety
checks and component
inspection procedures. if a fault exists that could compromise
safety, then no electrical supply shall be connected to the circuit
until it is satisfactorily dealt with. if the fault cannot be corrected
immediately but it is necessary to continue operation, an
