PRECHECK PRIOR TO SERVICE
[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, [General work
area] to [Ventilated area] shall be completed 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 toxic or flammable atmospheres. Ensure that the leak
detection equipment being used is suitable for use with all applicable 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 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. The ventilation should safely disperse any released refrigerant and preferably expel it
externally into the atmosphere.
