LOTO Incidents

In March, Xmo teams were undertaking reimaging work on a filling station that was
being developed. Prior to our team attending, as part of the overall site scope a
nominated electrical contractor had attended to isolate the electrical feeds prior to our
team undertaking the work.

Prior to commencing work on the fascia, our lead engineer, Andy Wyer carried out a
visual check at the main board to satisfy himself that the isolation procedure had been
carried out correctly and was satisfied that the work had been carried out by a specialist
electrical contractor with suitable and sufficient knowledge, experience, practical ability
and training; the company employed had an excellent reputation and Andy felt satisfied
and proceeded to access the canopy fascia.

Prior to actually starting the work, he followed our formal procedure and tested the feed
to satisfy himself that it was still safe to proceed; alarmingly, the feed to the fascia was
still live, despite apparently being disconnected at the board. The job was stopped
immediately, the principal contractor was advised and further investigation revealed that
the circuit breakers at the board were incorrectly labelled and the canopy fascia circuit
breaker was labelled as "security floods" so had not been disconnected.
