This Published Document provides guidance on the safe use of machinery supplied prior to the Supply of
Machinery (Safety) Regulations 1992 [3] (normally machines supplied before 1995).
It also provides guidance for users on:
— machinery designed to and manufactured in accordance with harmonized European machinery safety
standards insofar as it is necessary, when following the instructions supplied for use; and
— basic principles of safeguarding, with reference to current harmonized European machinery safety
standards.
It is intended that this guidance can be applied to any particular machinery during its modification,
refurbishment, upgrading or change of use in order to satisfy the Provision and Use of Work Equipment
Regulations 1998 [2]. See also the approved code of practice Safe use of work equipment [4].
However significant modification, refurbishment, upgrading or change of use to existing machinery that
results in, for example changes of the measures used to control a hazard(s) or the introduction of a new
hazard(s), can make it necessary to satisfy relevant requirements from the Supply of Machinery (Safety)
Regulations 1992 [3] in particular Schedule 3.
NOTE 1 PD 5304 is not intended to be used as an alternative to the current harmonized European machinery safety standards for
machinery supplied in accordance with the Supply of Machinery (Safety) Regulations 1992 [3].
NOTE 2 Attention is drawn to the Supply of Machinery (Safety) Regulations 1992 [3] for machinery which has been subject to
