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
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.
components containing the refrigerant are installed;
secondary circuit; the marking on the systems must be visible and legible;
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.
This solution must be communicated to the owner of the plant so that all parties can
be informed.
The initial safety controls envision:
possible formation of sparks;
