−
sparking;
that no live electrical components and wiring are exposed while charging, recovering or
−
purging the system;
that there is continuity of earth bonding.

Repairs to Sealed Components
Sealed electrical components shall be replaced.
Repair to Intrinsically Safe Components
Intrinsically safe components must be replaced.
Cabling
Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp
edges or any other adverse environmental effects. The check shall also take into account the

Transportation, marking and storage for units that employ flammable refrigerants
General
The following information is provided for units that employ FLAMMABLE REFRIGERANTS.
Transport of equipment containing flammable refrigerants
Attention is drawn to the fact that additional transportation regulations may exist with respect to
equipment containing flammable gas. The maximum number of pieces of equipment or the
configuration of the equipment permitted to be transported together will be determined by the
applicable transport regulations.
Marking of equipment using signs
Signs for similar appliances used in a work area are generally addressed by local regulations
and give the minimum requirements for the provision of safety and/or health signs for a work
location.
All required signs are to be maintained and employers should ensure that employees receive
suitable and sufficient instruction and training on the meaning of appropriate safety signs and
the actions that need to be taken in connection with these signs.
The effectiveness of signs should not be diminished by too many signs being placed together.
Any pictograms used should be as simple as possible and contain only essential details.
