I'm going by the names of the Engineer and technicians involved with this accident. It could well be a case of the latest trend in many Middle East countries, to employ Nationals rather than overseas qualified personnel.
From my personal experience of extensive working in the Middle East, is that the standard of most locally obtained qualifications are just not up to the recognised standards and the obvious lack of on the job experience. Another problem, is that they rarely see danger and will work in areas they have little to no working knowledge of. A so-called engineer, with his hands in a live and in service 11KV RMU is a typical example of what i'm talking about, probably thinking and relying on a pair of protective gloves that are rated at 33KV as being safe!!!
One of the biggest problems with local electricians and junior engineers in the Middle East, was stopping them from unnecessarily working live, especially where the means of isolation was distant from where they were working!!
These guys wouldn't think twice about working on MV switchboards to which they had no knowledge of at all.
I'm not saying this is the case here, but it wouldn't surprise me in the slightest if it was the case. i doubt if we'll ever get to know what really happened... lol!!!!
