7IMPORTANT SAFETY INSTRUCTIONS
ENGLISH
Prior to beginning work on systems containing flammable refrigerants, safety checks are necessary to
ensure that the risk of ignition is minimized. For repair to the refrigerating system, the following
precautions shall be complied with prior to conducting work on the system.
• Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of a flammable gas or
vapour being present while the work is being performed.
• General work area
All maintenance staff and others working in the local area shall be instructed on the nature of work
being carried out. Work in confined spaces shall be avoided.
• Checking for presence of refrigerant
The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure
the technician is aware of potentially flammable atmospheres. Ensure that the leak detection equipment
being used is suitable for use with flammable refrigerants,i.e. non-sparking, adequately sealed or
intrinsically safe.
• Presence of fire extinguisher
If any hot work is to be conducted on the refrigerating equipment or any associated parts, appropriate
fire extinguishing equipment shall be available to hand. Have a dry powder or CO2 fire extinguisher
adjacent to the charging area.
• No ignition sources
No person carrying out work in relation to a refrigerating system which involves exposing any pipe work
shall use any sources of ignition in such a manner that it may lead to the risk of fire or explosion.
All possible ignition sources,including cigarette smoking, should be kept sufficiently far away from the
site of installation, repairing, removing and disposal, during which 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 flammable hazards or ignition risks. “No Smoking” signs shall be displayed.
• Checks to the refrigerating equipment
Where electrical components are being changed, they shall be fit for the purpose and to the correct
specification.
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 flammable 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 suitably protected
against being so corroded.
• Checks to electrical devices
Repair and maintenance to electrical components shall include initial safety checks and component
inspection procedures. 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. This shall be
reported to the owner of the equipment so all parties are advised.
Initial safety checks shall include:
- Capacitors are discharged: this shall be done in a safe manner to avoid possibility of sparking.
