There are industries and situations [...] where shutting down sections are "forbidden", yet when they go off [...] the world does not end.
(paraphrasing)The point i am making is these reasons are monetary, and if you agree to work live, then this risk is taken to benefit someone else, financially.
I think these two points are worth remembering.
EAWR (a reminder)
Regulation 14 Work on or near live conductors
No person shall be engaged in any work activity on or so near any live conductor
(other than one suitably covered with insulating material so as to prevent danger)
that danger may arise unless –
(a) it is unreasonable in all the circumstances for it to be dead; and
(b) it is reasonable in all the circumstances for him to be at work on or near
it while it is live; and
(c) suitable precautions (including where necessary the provision of suitable
protective equipment) are taken to prevent injury
Regulation 29 Defence
In any proceedings for an offence consisting of a contravention of [regulations 4(4),
5, 8, 9, 10, 11, 12, 13, 14, 15 or 16,]* it shall be a defence for any person to prove
that he took all reasonable steps and exercised all due diligence to avoid the
commission of that offence.
Are you confident you could prove you took all reasonable steps?
