Poorly Wired MID

Please see enclosed safety alert regarding a poorly wired MID shared with us by BP.

Unfortunately, poorly wired circuits on site are common, and this is the second most common category
of potential incident reports we receive. We have recorded 370 electrical PIs related to poor electrical
condition, 20 PI’s just this year. In 36 of those PI’s this resulted in the equipment having no earth, and
24 resulted in exposed live parts.

Before working on any equipment always isolate the energy source (LOTO), and test the circuit to
ensure it is dead. However beware that circuits are regularly min-labelled and automatic switching can
mean circuits are switched on without warning, this can result in you inadvertently isolating the wrong
circuit and testing a circuit that is only dead due to the light levels being good. Always test a cable you
think is dead immediately before touching it. If possible, avoid touching any exposed conductor.

If you see any poorly installed electrical equipment, always report it – you may be saving somebodies
life.

If you are in doubt as to which circuit needs to be isolated, contact your line manager so an electrician
can investigate.

We are all a product of learning. Every skill we have; everything we know; everything we believe and everything we do has
been learned throughout the course of our lives. Some of us learn best by studying graphs and charts, some through visual
presentations, and some by reading detailed text books. It is important that we receive information in a format that works for
us as individuals! That’s why at Xmo Strata we use a variety of communication platforms such as bulletins, newsletters,
videos etc. However, if you feel there is a better way for us to share health and safety information, please let us know.
Ultimately, your safety is in your hands – but we will do all we can to keep you well informed!
