IX.Troubleshooting
1. Information on servicing
1) Checks to the area
Prior to beginning work on systems containing flammable 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 flammable gas or vapour being present while the work is being performed.
3) General work area 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.
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
flammable atmospheres. Ensure that the leak detection equipment being used is suitable for
use with flammable refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
5) Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated parts,
appropriate fire extinguishing equipment shall be available to hand. Have a dry powder or
CO2 fire extinguisher adjacent to the charging area.
6) No ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing
any pipe work that contains or has contained flammable refrigerant 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
