26.3 The volume of the waste compacting chamber shall not exceed 2 cubic feet (0.057 cubic meters).
Exception: The volume of the waste compacting chamber may exceed 2 cubic feet when a removable
waste container is not in place if an interlock is provided to prevent operation of the compactor when the
container is not in place or if the waste compacting space is divided into sections that do not exceed 2
cubic feet of an unobstructed or occupiable space. Consideration will be given to container holding
brackets, shelves, or the like that will effectively reduce the volume.

27 Enclosure and Guards

27.1 A part capable of creating a risk of injury to persons shall be enclosed or guarded.
27.2 With reference to 27.1 a part presenting a risk of injury to persons shall be considered acceptably
guarded if it is within the enclosure or casing of the appliance and cannot be contacted with the probe
illustrated in Figure 7.1.
Exception No. 1: An opening in the integral enclosure of a motor that is not used in a hand-supported
portion of an appliance is acceptable if a moving part cannot be contacted by the probe illustrated in
Figure 7.4.
Exception No. 2: A part or portion of a part that is necessarily exposed to perform the work function need
not be enclosed but, when necessary, guarding shall be provided.
27.3 During the examination of an appliance to determine whether it complies with the requirements in
27.2, a part of the enclosure that may be removed without the use of a tool (to attach an accessory, to
make an operating adjustment, or for other reasons) is to be opened or removed.
Exception: A part need not be opened or removed provided the appliance is marked in accordance with
49.19.
27.4 The material of a part – an enclosure, frame, guard, or the like – the deterioration of which might
result in a risk of injury to persons, shall have such properties as to meet the demand of expected loading
conditions.
