Shackle lines
31.—(1) No person may operate a shackle line unless—
(a)poultry suspended from it are kept clear of any object which may cause avoidable pain, distress or suffering, including when their wings are outstretched, until they are stunned;
(b)it is possible to relieve any avoidable pain, distress or suffering which poultry suspended from shackles appear to be suffering or to remove poultry from the shackles; and
(c)the speed at which the shackle line is operated is such that any act or operation intended to be performed in relation to, or on, poultry suspended from it can be performed without undue haste and with proper regard for the welfare of the poultry.
(2) No person may, in connection with the stunning or killing of poultry, use a shackle line, machine or other equipment unless it is used in connection with the stunning or killing of poultry of the type, size and weight for which it was designed, save in an emergency where it is used to relieve suffering.
