the area around the work area must be isolated.
Guarantee that the conditions inside the area are safe by verifying the inflammable
material.
d. Check the presence of refrigerant
The area must be controlled with a specific refrigerant detector before and during
the performance of the job, in a way to guarantee that the technician is informed
regarding the presence of potentially inflammable atmospheres.
Check the leak detector equipment used is suitable for use with inflammable refrigerants,
i.e. does not cause sparks, is suitably sealed or intrinsically safe.
e. Presence of extinguishers
Whenever work must be performed on the refrigeration system at high temperatures
or on relative components, a suitable fire-prevention system must be prepared.
Position Co2 or dry powder extinguishers in proximity of the loading area.
f. No source of ignition
no-one working in the refrigeration systems and exposed to contact with the piping
that contains or contained inflammable refrigerant, must use sources of ignition in
order to prevent the risk of fire or explosion.
every possible source of ignition, among which cigarette smoke, must be kept at a
due distance from the place of installation, repair, removal or disposal, where there
is a risk of the refrigerant liquid leaking into the surrounding space.
Before performing the job, the area surrounding the appliance must be controlled
in order to ascertain that there are no inflammable substances or risks of ignition
present.
no SmoKinG signs must be displayed.
g. Ventilated area
make sure that the area is open or suitably ventilated before interacting with the
system or performing any operation at high temperatures.
ensure constant ventilation during the operations period.
Ventilation must safely disperse all refrigerant released and, if possible, expel it outside
into the atmosphere.
h. Refrigeration system checks
If modified, the electric components must be suitable for the purpose and compliant
with the correct specifications.
always follow the manufacturer's guide lines relative to maintenance and technical
after-sales assistance. if in doubt, consult the manufacturer's technical after-sales
service.
The plants that use inflammable refrigerants must be subjected to the following
verifications:
• the dimension of the load must be compliant with the chamber in which the
components containing the refrigerant are installed;
• the plants and ventilation outlets must operate adequately and not be obstructed;
• if an indirect refrigeration circuit is in use, check the presence of refrigerant in the
secondary circuit; the marking on the systems must be visible and legible;
