SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the following when servicing an
appliance with R290.
Checks to the area
Before 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 before
conducting work on the system.
Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of
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 the 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 before 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.
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 CO
2
fire extinguisher adjacent to the charging area.
No ignition sources
No person carrying out work in relation to a refrigeration system that involves exposing
any pipework 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 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.
