during work to ensure that the technician is warned of potentially flammable
atmospheres. Ensure that the leak-detection equipment used is suitable for use with
flammable refrigerants, i.e., non-sparking, adequately sealed, or intrinsically safe.
1.5. Presence of fire extinguishers
If any high-temperature work is to be carried out on the refrigeration equipment or
any associated parts, suitable extinguishing equipment must be available. Always
have a dry-powder or CO2 fire extinguisher nearby the load area.
1.6. Absence of ignition sources
No person carrying out work related to a refrigeration system involving the exposure
of piping containing or having contained flammable refrigerant should use any
source of ignition in such a manner as to create a risk of fire or explosion. All possible
sources of ignition, including cigarette smoking, should be kept far enough away
from the installation, repair, pick-up, and disposal site, where flammable refrigerant
can be released into the surrounding space. Before work starts, the area around the
equipment must be thoroughly examined to ensure that no danger or risk of ignition
is present. "No Smoking" signs must be displayed.
1.7. Ventilation
Ensure that the area is outdoors or adequately ventilated before intervening in the
system or carrying out any work at high temperature. Proper ventilation must be kept
at all times during work. Ventilation should safely disperse any refrigerant released
and preferably expel it externally to the atmosphere.
1.8. Verification of refrigeration equipment
When electrical components are replaced, they must be fit for purpose and to the
correct specification. The manufacturer's maintenance and service guidelines
must be followed at all times. In case of doubt, refer to the manufacturer's technical
department for assistance. The following checks must be applied to installations
using flammable refrigerants:
The charge size is in accordance with the size of the room within which the refrigerant
containing parts are installed.
Ventilation machinery and outlets are properly operated and unobstructed.
If an indirect cooling circuit is used, the secondary circuit must be checked for the
