IMPORTANT SAFEGUARDS (4/6)
Warning: Any person who is involved with working on or breaking
into a refrigerant circuit should hold a current valid certificate from
an industry-accredited assessment authority, which authorizes their
competence to handle refrigerants safely in accordance with an
industry, recognized assessment specification.
Warning: Servicing shall only be performed as recommended by
the equipment manufacturer. Maintenance and repair requiring
the assistance of other skilled personnel shall be carried out under
the supervision of the person competent in the use of flammable
refrigerants.
43. 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.
44. 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.
45. 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.
46. 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.
47. 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.
