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 are manufactured with intrinsically
corrosion resistant materials or are appropriately protected from corrosive agents.
i. Check the electric devices
The repair and maintenance interventions of electric components must envision initial
safety checks and component inspection procedures.
In the case of a fault which may compromise safety, no electric power supply must
be connected to the circuit until it has been suitably repaired.
If the fault cannot be repaired immediately, but the operation must be continued, use
a suitable temporary solution.
