Transportation, marking and storage 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 generally are 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.
Disposal of equipment using flammable refrigerants
See national regulations.
Storage of equipment/appliances
The storage of equipment should be in accordance with the manufacturer’s instructions. Storage
of packed (unsold) equipment Storage package protection should be constructed such that
mechanical damage to the equipment inside the package will not cause a leak of the refrigerant
charge. The maximum number of pieces of equipment permitted to be stored together will be
determined by local regulations.
