2-6. Presence of
fi
re extinguisher
•
If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate
fi
re extinguishing
equipment shall be available at hand.
•
Have a dry powder or CO
2
fi
re extinguisher adjacent to the charging area.
2-7. No ignition sources
•
No person carrying out work in relation to a refrigerating system which involves exposing any pipe work that contains
or has contained
fl
ammable refrigerant shall use any sources of ignition in such a manner that it may lead to the risk
of
fi
re or explosion. He/She must not be smoking when carrying out such work.
•
All possible ignition sources, including cigarette smoking, should be kept suf
fi
ciently far away from the site of installation,
repairing, removing and disposal, during which
fl
ammable refrigerant can possibly be released to the surrounding space.
•
Prior to work taking place, the area around the equipment is to be surveyed to make sure that there are no
fl
ammable
hazards or ignition risks.
•
“No Smoking” signs shall be displayed.
2-8. Ventilated area
•
Ensure that the area is in the open or that it is adequately ventilated before breaking into the system or conducting
any hot work.
•
A degree of ventilation shall continue during the period that the work is carried out.
•
The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
2-9. Checks to the refrigerating equipment
•
Where electrical components are being changed, they shall be
fi
t for the purpose and to the correct speci
fi
cation.
•
At all times the manufacturer’s maintenance and service guidelines shall be followed.
•
If in doubt consult the manufacturer’s technical department for assistance.
•
The following checks shall be applied to installations using fl
ammable refrigerants.
- The actual refrigerant charge is in accordance with the room size within which the refrigerant containing parts are installed.
- The ventilation machinery and outlets are operating adequately and are not obstructed.
- If an indirect refrigerating circuit is being used, the secondary circuit shall be checked for the presence of refrigerant.
- Marking to the equipment continues to be visible and legible. Markings and signs that are illegible shall be corrected.
- Refrigerating pipe or components are installed in a position where they are unlikely to be exposed to any substance
which may corrode refrigerant containing components, unless the components are constructed of materials which
are inherently resistant to being corroded or are properly protected against being so corroded.
2-10. Checks to electrical devices
•
Repair and maintenance to electrical components shall include initial safety checks and component inspection
procedures.
•
Initial safety checks shall include but not limit to:-
- That capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking.
- That there is no live electrical components and wiring are exposed while charging, recovering or purging the system.
- That there is continuity of earth bonding.
•
At all times the manufacturer’s maintenance and service guidelines shall be followed.
•
If in doubt consult the manufacturer’s technical department for assistance.
•
If a fault exists that could compromise safety, then no electrical supply shall be connected to the circuit until it is
satisfactorily dealt with.
•
If the fault cannot be corrected immediately but it is necessary to continue operation, an adequate temporary solution
shall be used.
•
The owner of the equipment must be informed or reported so all parties are advised thereinafter.
