I saw news footage on TV last night after I posted the link.
While tragic, this was a very avoidable accident.
It was reported that an unlicensed, uninsured siding contractor without a building permit was doing a siding job on the front of a three story house type building with businesses on the first floor.
The power poles were about 6' from the front and had 3 phase 13.8kv primary on cross arms with bare conductors at the same level as the roof.
A piece of the aluminum about 6? wide came in contact with the primary line and killed one person and injured another. This also started a fire, melted the scaffold legs and trapped two more workers on the roof.
I guess the fault lasted for a couple of minutes.
It was reported that another contractor was siding another part of the building. This contractor contacted the power company and had the secondary service drop covered (with the insulated conductors) with the orange sleeves before he started his project.
The contractor that was doing the front did not call the power company to have the BARE primary covered.
