Safety and Environmental Guidelines
• Patient Vicinity UL60601-1 (USA)
WARNING WARNING
Environmental Dangers
All devices meeting IEC60950 must be kept outside the patient environment as defined
in IEC60601-1-1, unless the devices, according to IEC60601-1-1, are equipped with the
following:
A) Additional Earth Protection
or:
B) An Extra Isolating Transformer
WARNING WARNING
Commercial devices such as laser cameras, printers, VCRs and external monitors,
usually exceed allowable leakage current limits and, when plugged into separate AC
outlets, are in violation of patient safety standards. Suitable electrical isolation of such
external AC outlets, or the provision of extra protective earth for the device, is required
in order to meet UL60601-1 and IEC60601-1-1 standards for electrical leakage.
2.12.20DV (UL60601-1:2003)
In area in which patients are normally cared for, the patient vicinity is the space with surfaces
likely to be contacted by the patient or attendant who can touch the patient. This encloses a
space within the room 1.83 m (6 ft.) beyond the perimeter of the bed (examination table, dental
chair, treatment booth, and the like) in its intended location, and extending vertically 2.29 m
(7.5 ft.) above the floor.
