5. Information On Servicing
a. Checks to the area
Before working on systems containing ammable refrigerants, it is necessary to
ensure that the risk of ignition is minimized. Comply with the following precautions
before working on or repairing the refrigerating system.
b. Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of a
ammable gas or vapor being present while the work is being performed.

All maintenance staff and other people 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 off. Ensure that the conditions
within the area have been made safe through control of the ammable material.
d. Checking for the presence of refrigerants
The area shall be checked with an appropriate refrigerant detector prior to
and during work to ensure that 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., non-sparking, adequately sealed,
or intrinsically safe.
e. Presence of a re extinguisher
If any hot work is to be conducted on the refrigeration equipment or any associated
parts, appropriate re extinguishing equipment shall be on hand. Be sure to have a
dry powder or CO2 re extinguisher adjacent to the charging area.
f. No ignition sources
No person carrying out work in relation to a refrigeration system which involves
exposing any pipe work that contains or used to contain ammable refrigerant shall
use any sources of ignition in such a manner that may lead to the risk of re or an
