Safety Regulations for Service and Repair
Repairs must only be carried out by authorized service personnel and only using
genuine spare parts.
1. Checks to the Area
Prior to beginning of work on systems containing flammable refrigerants, safety
checks are necessary to ensure that the risk of ignition is minimized. For repair of
the refrigerating system, the following precautions shall be complied with prior to
conducting work on the system.
2. Work procedure
Work shall be undertaken under a controlled procedure so as to minimize the risk of
flammable gas or vapor being present while the work is being performed.
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.
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 detection equipment being used is suitable for use with flammable
refrigerants, i.e. non-sparking, adequately sealed or intrinsically safe.
5. 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 at hand. Have a dry
powder or CO2 fire extinguisher adjacent to the charging area.
6. 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.
