2.2SAFETY PRECAUTIONS ON SERVICING
Please follow these warnings when to undertake the followings
when servicing an appliance with R32.
2.2.1 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 conducting
work on the system.
2.2.2 Work procedure
Work shall be undertaken under a controlled procedure so as to
minimize the risk of a flammable gas or vapor being present while
the work is being performed.
2.2.3 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 work space
shall be sectioned off. Ensure that the conditions within the area
have been made safe by control of flammable material.
2.2.4 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. no sparking, adequately sealed or intrinsically
safe.
2.2.5 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 to hand. Have a dry powder or CO2 fire
extinguisher adjacent to the charging area.
