·      lack of experience and knowledge

prevents them from using the appliance safely without supervision or instruction;

–    children playing with the appliance.

NOTE 1 Attention is drawn to the fact that

–     for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;

–    in many countries, additional requirements are specified by national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities.

NOTE 2 This standard does not apply to

–     appliances intended to be used in the open air;

–     appliances designed exclusively for industrial purposes;

–     appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);

–     appliances incorporating a battery intended as a power supply for the refrigerating function;

–     appliances assembled on site by the installer;

–      appliances with remote motor-compressors;
