7.3 Specialist's Manual
Aptitude requirement for maintenance man(repairs should be
done only be specialists).
1. All the work men who are engaging in the refrigeration
system should bear the valid certification awarded by the
authoritative organization and the qualification for dealing
with the refrigeration system recognized by this industry.
2. It can only be repaired by the method suggested by the
equipment's manufacturer. If it needs other technician to
maintain and repair the appliance, they should be
supervised by the person who bears the qualification for
using the flammable refrigerant.
7.3.1 Safety preparation work before installation
• The safety must be inspected before maintaining the
appliances with the flammable refrigerant for reducing the
flammable hazard to the lowest.
• Work shall be undertaken under a controlled procedure so
as to minimize the risk of a flammable gas or vapour being
present while the work is being performed.
7.3.2 Detection of flammable refrigerants
Under no circumstances shall potential sources of ignition be
used in the searching for or detection of refrigerant leaks. A
halide torch (or any other detector using a naked flame) shall
not be used.
7.3.3 Environment checking
• All maintenance staff and others working in the local area
shall be instructed on the nature of work being carried out.
Work in confined spaces shall be avoided. The area around
the workspace shall be sectioned off. Ensure that the
conditions within the area have been made safe by control
of flammable material.
• The area shall be checked with an appropriate refrigerant
detector prior to and during work, to ensure the technician
is aware of potentially toxic or flammable atmospheres.
Ensure that the leak detection equipment being used is
suitable for use with all applicable refrigerants, i.e. non-
sparking, adequately sealed or intrinsically safe.
• No person carrying out work in relation to a refrigeration
system which involves exposing any pipe work shall use any
sources of ignition in such a manner that it may lead to the
risk of fire or explosion. All possible ignition sources,
including cigarette smoking, should be kept sufficiently far
away from the site of installation, repairing, removing and
