WARNINGS
• Transport of equipment containing flammable refrigerants
See transport regulations
• Marking of equipment using signs
See local regulations
• Disposal of equipment using flammable refrigerants
See national regulations.
• Storage of equipment/appliances
The storage of equipment should be in accordance with the
manufacturer's instructions.
• Storage of packed (unsold) equipment
Storage package protection should be constructed such that
mechanical damage to the equipment inside the package will not
cause a leak of the refrigerant charge.
The maximum number of pieces of equipment permitted to be
stored together will be determined by local regulations.
• Information on servicing
1. Area checks
Prior to beginning work on systems containing flammable refrige-
rants, safety checks are necessary to ensure that the risk of igni-
tion is minimised. For repair to the refrigerating system, the following
precautions shall be complied with prior to conducting work on the
system.

2. Work procedure

Works shall be undertaken under a controlled procedure so as to
minimise the risk of a flammable gas or vapour being present while
the work is being performed.
3. 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. The area around the work space shall be
sectioned off. Ensure that the conditions within the area have been
made safe by control of flammable material.
4. 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. no sparking, adequately sealed or intrinsically safe.
5. Presence of fire extinguisher
If any hot work is to be conducted on the refrigeration equipment or
any associated parts, appropriate fire extinguishing equipment shall
be available on hand. Have a dry power or CO2 fire extinguisher next
to the charging area.
6. No ignition sources
No person carrying out work with a refrigeration system which involves
exposing any pipe work that contains or has contained flammable
refrigerant shall use any sources of ignition in such a manner that
it may lead to 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
flammable 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.
7. Ventilated area
Ensure the work 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.
8. Checks to the refrigeration 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.
