Important safety instructions for repairing a unit with refrigerant R290:
1.
check the environment
Before starting work on systems containing flammable refrigerants, safety checks are required
to ensure that the risk of ignition is minimised. When repairing the refrigerant system, the
following safety precautions must be observed and adhered to before any work is carried out on
the system.
Procedure
Work must be carried out under a controlled procedure to minimise the risk of flammable gases
or vapours being present during the execution of the work.
2. general work area
All maintenance personnel and other persons in the vicinity must be instructed on the type of
work to be carried out. Work in confined spaces must be avoided. The area around the work
area must be partitioned off. Make sure that the conditions in the work area have been made
safe by controlling the flammable material.
3. check for the presence of refrigerants
The area must be checked with a suitable refrigerant detector before and during work to ensure
that the technician is aware of possible flammable atmospheres. Ensure that the refrigerant
detector used is suitable for working with flammable refrigerants, e.g. non-sparking, adequately
sealed and intrinsically safe.
4. presence of a fire extinguisher
If hot work is to be carried out on the refrigerant equipment or associated parts, suitable fire
extinguishing equipment must be readily available. Make sure that a dry powder fire
extinguisher or a CO2 fire extinguisher is nearby.
