Maintenance & Information
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 conducting work on the system. prolonged period of no
usage.
WORK PROCEDURE
Work shall be undertaken under a controlled procedure to minimise the risk of a flammable gas or
vapour being present while the work is being performed.
TRANSPORTATION
When storing or moving the heat pump, the heat
pump should be at the upright position.
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 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 refrigeration 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.
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 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.
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.
