INSTRUCTIONS FOR REPAIRING APPLIANCES CONTAINING R290
1 GENERAL INSTRUCTIONS
1.1 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 minimized. For repair to the refrigerating system,
the following precautions shall be complied with prior to con-ducting work on the system.
1.2 Work procedure
Work shall be undertaken under a controlled procedure to minimize the risk of a flammable gas
or vapor being present while the work is being performed.
1.3 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
workspace shall be sectioned off. Ensure that the conditions within the area have been made
safe by control of flammable material.
1.4 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

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
