Safety note-as part of the planned maintenance special checks should be made to ensure:
All changes (including removal and addition of parts) and extensions conform to the right code
of practice.
Changes in the vicinity of the installation do not affect the safety of the operation e.g. proximity
of electricity to fuel gases, oils and combustibles near to oxygen, illicit use of a pipeline as an
electrical conductor or as a support for other items.
