PROTECTION AGAINST RISK OF INJURY TO PERSONS

23.1 This section gives the requirements for construction and performance for an appliance the operation

of which may involve a risk of injury to persons.

23.2 During the examination of an appliance with respect to a risk of injury to persons, the general

requirements for such features as materials, enclosures, guards, and the like, will be applied along with

appropriate requirements for tests, construction, markings, guards, and the like, that may apply to an

appliance. The requirements speciﬁed in this standard apply to appliances of common construction.

Speciﬁc features that are not contemplated will be given appropriate consideration. A speciﬁc requirement

pertaining to one type of appliance takes precedence over the requirements speciﬁed in General, Section

24.

24.1 If the operation and maintenance of an appliance by the user involves a risk of injury to persons,

protection shall be provided to reduce the likelihood of such a risk.

24.2 With reference to the requirement in 24.1, consideration shall be given to reasonably foreseeable

misuse of the appliance.

25.1 An enclosure, a frame, a guard, a handle, or the like shall not be sufficiently sharp to cause a risk

of injury to persons in normal maintenance or use.

25.2 Whenever referee measurements are necessary to determine that a part as mentioned in 25.1 is not

sufficiently sharp to constitute a risk of injury to persons, the method described in the requirements for

determination of sharpness of edges on equipment, UL 1439, is to be employed.

26.1 The compacting action shall be totally enclosed within the appliance. A door, drawer, or other

opening providing access to the compacting compartment shall be interlocked so as to stop completely all

moving parts that may cause injury to persons within 5 seconds if the moving part can be contacted after

the door has been opened 2 inches (50.8 mm) or less. See 26.2.

26.2 With reference to 26.1, for an opening having a minor dimension less than 1 inch (25.4 mm), contact

with a moving part that may cause injury to persons is to be determined by using the probe illustrated in

Figure 7.1. For a 1 to 2 inch (25.4 to 50.8 mm) opening, the distance from the plane of the opening to a

moving part shall be in accordance with Table 26.1. For an opening having a minor dimension between

two values in Table 26.1, the distance from an opening to a moving part shall not be less than that

determined by appropriate interpolation between corresponding values in the right-hand column of the

table. The minor dimension of the opening is considered to be the diameter of the largest cylindrical probe

having a hemispherical tip that can be inserted through the opening with a force of 5 pounds (22.24 N).
