d. Check the presence of refrigerant
 Theareamustbecontrolledwithaspecic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inammableatmospheres.
 Checktheleakdetectorequipmentusedissuitableforusewithinammable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re-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inammablerefrigerant,mustusesourcesofignitionin
ordertopreventtheriskofre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inammable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modied,theelectriccomponentsmustbesuitableforthepurposeandcompliant
withthecorrectspecications.
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 inammable refrigerants must be subjected to the following
verications:
• 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.
