Article 13

     1. All dangerous parts of machinery shall be effectively guarded,
unless they are in such a position or of such a construction as to  be
as safe as they would be if effectively guarded.
     2. Effective measures shall be provided for promptly cutting  off
the  power to any machinery in respect of which this is necessary,  in
an emergency.
     3. When  any  cleaning,  maintenance  or  repair  work that would
expose any person to danger has to be  undertaken  on  machinery,  the
machinery  shall  be  stopped  before  this work is begun and adequate
measures shall be  taken  to  ensure  that  the  machinery  cannot  be
restarted   until  the  work  has  been  completed:  Provided  that  a
responsible person may restart the machinery for the  purpose  of  any
testing  or adjustment which cannot be carried out while the machinery
is at rest.
     4. Only an authorised person shall be permitted to -
     (a) remove any guard where this is necessary for the  purpose  of
the work being carried out;
     (b) remove a safety device or make it inoperative for the purpose
of cleaning, adjustment or repair.
     5. If any guard is removed,  adequate precautions shall be taken,
and the guard shall be replaced as soon as practicable.
     6. If any safety device  is  removed  or  made  inoperative,  the
device  shall  be  replaced  or  its  operation  restored  as  soon as
practicable and measures shall be taken to ensure  that  the  relevant
equipment  cannot  be  used  or inadvertently started until the safety
device has been replaced or its operation restored.
     7. For the purpose of this Article, the term "machinery" includes
any  lifting  appliance,  mechanised  hatch  cover   or   power-driven
equipment.
