INSTRUCTIONS FOR REPAIRING APPLIANCES CONTAINING R290
GENERAL INSTRUCTIONS
CHECKS TO THE AREA
· Prior to beginning work on systems containing flammable refrigerants, safety checks are
necessary to ensure that the risk of ignition is minimised. For repair to the refrigerating system,
the following precautions shall be complied with prior to con-ducting work on the system.
WORK PROCEDURE
· Work 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.
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 workspace
shall be sectioned off. Ensure that the conditions within the area have been made safe by control
of flammable material.
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
tection equipment being used is suitable for use with flammable refrigerants, i.e. nonsparking,
adequately sealed or intrinsically safe.
PRESENCE OF FIRE EXTINGUISHER
· If any hot work is to be conducted on the refrigeration equipment or any associated parts,
propriate fire extinguishing equipment shall be available to hand. Have a dry powder or CO fire
2
extinguisher adjacent to the charging area.
NO IGNITION SOURCES
· No person carrying out work in relation to 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 the risk of fire or explosion. All possible ignition sources,
including igarette 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.
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.
CHECKS TO THE REFRIGERATION EQUIPMENT
· Where electrical components are being changed, they shall be fit for the purpose and to the
