in the US we have OSHA, and what is refered to as 'sub part S' , we also have NFPA 70E.
sub-part S can be found in
OSHA's on line page.
NFPA 70E can be had for about $30 here, it is a concise document , one i wish was at least
refered to in my apprenticeship.
In a nutshell, both detail the basics of live work, proper posting, arc-flast zones, PPE, etc. for any electrical worker to
legally' do live work.
I have 2 reservations about this.....
#1- OSHA (last i knew) , did not recongnize 70E. One can assume OSHA training here through the private sector but it is usually something found in the cities at exorbitant rates.
One flyer in my mail asked $650 for a weekend course, and was 4 hrs away. Subseqently the
'little guy' here doesn't receive much safety training because of this.
Nor is anything nearby and/or convieniently had for those well heeled.
#2 After one completes the training live work is expected under what i would consider a grey criterior .
The 'employee'-'employer' card is played against the 'employee' who cannot challenge the job at hand regardless of hazard level .
Given the latter,
and this forums insightful knowledge of our electrical system vs. those elsewhere on the planet, i'm fairly convinced that concerns for corporate liabilty are more a motive than personal safety here.
