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;
• illegible markings and signs must be corrected;
• the pipe or refrigeration components must be installed in a position where
it is improbable that they are exposed to substances that could corrode
the components containing the refrigerant, unless the components
